Are you thinking about heading to the beach in Florida? You may want to reconsider. The "Sunshine State" and the Southeast are experiencing heavy rainfall, with a stalled front causing rain for the next few days. Rain showers will continue not only in Florida but throughout the Southeast. A frontal boundary stretched across the Gulf Coast of Louisiana, Mississippi, and Alabama will stick around for several days. This front will bring in additional rainfall before the influence of PTC Six (<a target="_blank" rel="noopener noreferrer nofollow" class="editor-rtfLink" href="https://www.weathernationtv.com/news/tropical-system-expected-to-develop-this-week">related article here</a>) brings heavy rain to Louisiana by Wednesday. &nbsp;<img src="https://media.weathernationtv.com/app/uploads/2024/09/Screenshot 2024-09-09 060848-1725883866809.png">Portions of Mississippi, Alabama, Georgia, and the Carolinas could see flooding due to the heavy nature of the rain. Fortunately, there's not a high risk of flooding, but at least some ponding of water will be possible, along with minor flooding in isolated spots.<img src="https://media.weathernationtv.com/app/uploads/2024/09/Screenshot 2024-09-09 060912-1725883827918.png">Expect heavy rain near the front, with the strongest storms and highest rainfall rates from the late morning through the afternoon, when flood potential will be peaking.<video src="https://media.weathernationtv.com/app/uploads/2024/09/2024-09-09 06-09-41-1725883839233.mp4" controls="true" width="100%"></video>The second west low that lingers in the Gulf will move back to the north next week, bringing flood chances back to Texas and Louisiana.

As we approach the climatological peak of the tropical season in the Atlantic basin, it's starting to look like it! The most pressing threat to land at this time will be what develops in the Western Gulf in the next few days, read more about it here:<a target="_blank" rel="noopener noreferrer nofollow" href="https://www.weathernationtv.com/news/tropical-system-expected-to-develop-this-week">PTC 6 Swirling in the Gulf</a>There are a few other areas in the Atlantic to monitor, one with a high chance and the other with a medium chance to develop. One has been dubbed 92L by the National Hurricane Center, meaning they can run models for the system.<img src="https://media.weathernationtv.com/app/uploads/2024/09/92 Spaghettis-1725884410715.png">This system is expected to stay north of the Leeward Islands, but could still bring impacts like some rain and high surf to the area.<img src="https://media.weathernationtv.com/app/uploads/2024/09/second wave-1725884415996.png">The other system behind 92L has a slightly lower chance of development.

Hot and dry weather has been a theme of the Summer for many out West. As temperatures soared into the 110-115 range this past weekend, more wildfires broke out thanks to the dry vegetation. Related article: <a target="_blank" rel="noopener noreferrer nofollow" href="https://www.weathernationtv.com/news/building-heat-for-the-southwest-this-week">West Coast Scorcher</a>. With hot temperatures lingering and winds kicking up in the afternoon, more Red Flag Warnings greet those in Wyoming, Montana, Nevada, and Oregon. <img src="https://media.weathernationtv.com/app/uploads/2024/09/Red Flag Warnings-1725885427581.png">The northwest has been plagued by wildfire smoke already, with multiple fires ongoing coming into the weekend. Since then, places like California and Nevada have had plenty of fires spring up. <h2>Rail Ridge Fire</h2>A wildfire in Oregon, which was started by lightning back on September 2, has grown to over 135,000 acres. Close to 150 homes are being threatened by this blaze<img src="https://media.weathernationtv.com/app/uploads/2024/09/Rail Ridge Fire-1725885456612.png"><h2>Line Fire</h2>The Line Fire has prompted evacuations in San Bernardino County as flames burned over 20,000 acres over the weekend. <div class="twitter-tweet" style="display: flex; justify-content: center" data-twitt-post-id="1833120673797193838" src="https://x.com/WeatherNation/status/1833120673797193838"></div><h2>Davis Fire</h2>Near Reno, the Davis Fire has brought smoky skies to the Lake Tahoe area, with zero containment so far. <img src="https://media.weathernationtv.com/app/uploads/2024/09/Davis Fire-1725885547837.png">We will have to wait until the middle of the week before some relief comes to those out west. A strong trough will swing through, which will drop the temperatures, bring rain chances, and hopefully sweep the smoke away. <video src="https://media.weathernationtv.com/app/uploads/2024/09/2024-09-09 06-39-34-1725885594453.mp4" controls="true" width="100%"></video> For more details on the cooldown, catch your West Regional Forecast at :50 past every hour!

SOUTHWEST - Numerous records broke this weekend in California and Arizona after a dangerous heat left millions under heat alerts. On Sunday, new records broke all across the Los Angeles area where temperatures soared into the triple digits. Here are some locations that tied previous records for September 8th.<img src="https://media.weathernationtv.com/app/uploads/2024/09/Screenshot 2024-09-08 211816-1725852012783.jpg">Excessive Heat Alerts remain in effect now through Tuesday across California and Arizona. Temperatures above 115° will be possible during this time.<img src="https://media.weathernationtv.com/app/uploads/2024/09/Screenshot 2024-09-08 212109-1725852077236.jpg">Many spots will be at least 10° above average through Monday. Make sure you are staying hydrated and planning for the heat! The coast will also be relatively warm, but cooler than areas further inland. For example, Downtown Los Angeles is expected to hit the triple digits again Monday, but the coast of LA, near Santa Monica, will sit 10° cooler.<img src="https://media.weathernationtv.com/app/uploads/2024/09/mon - wed highs so cal-1725884693774.png">Confidence in warmer than normal temperatures sticking around in the long-range forecast for most of the Intermountain West is quite strong, however, the western states look to drop to more seasonal levels if not a little below average. This will be a nice break from the extreme heat. Many people in the Pacific Northwest do not have air-conditioning so these rounds of extreme heat can be extra dangerous. The Climate Prediction Center gives Seattle and Portland odds to be below average into the middle of September.<img src="https://media.weathernationtv.com/app/uploads/2024/09/Screenshot 2024-09-08 143737-1725827863430.png"> More on your Western Regional Forecast can always be found :50 past the hour on WeatherNation.

Pumpkin spice lattes are back at coffee shops, and the Halloween décor has popped into retail locations, which means fall is on the horizon. As the summer season wraps up meteorologically on August 31st and astronomically on September 22nd, Mother Nature heralds in the tell-tale signs that Autumn has arrived with the changing colors of the leaves.&nbsp;&nbsp;But forecasting the changing leaves is a difficult task with variables that can sometimes be difficult to track. &nbsp;Weather plays an important role in the timing of when leaves will change, and while some locations have seasonal averages for peak foliage, nature has the final say on when the brilliant colors will arrive.&nbsp;WHY LEAVES CHANGE COLOR:&nbsp;The change in season sparks the transformation within deciduous trees. Deciduous trees typically have large, broad leaves and use flowers to reproduce; think your oak and maple types. These trees get the deciduous classification from the Latin word “dēciduus” which means “to fall” because of their tendency to drop their leaves once they reach maturity. &nbsp;Coniferous trees are your evergreen trees. These trees tend to have needles or scales and reproduce using cones. Coniferous trees typically hold their needles year-round as they help with water conservation for the tree to continue producing food for itself during the long winter and summer months.&nbsp;Because of the deciduous tree's leaf shape, they are the ones that transform into brilliant plumes of color as the days get shorter. &nbsp;So, what’s sparking the change?&nbsp;According to the Smithsonian, in fall, the days start getting shorter, meaning less sunlight, and in turn, cooler temperatures. This signals the trees to end their food making process. The chlorophyll within the leaves that helps conduct photosynthesis begins to fade allowing other chemicals within the leaves to shine. &nbsp;<img src="https://media.weathernationtv.com/app/uploads/2024/08/Screenshot 2024-08-28 135520-1724874946511.png">WHAT DO FORECASTS LOOK FOR:&nbsp;“The ideal weather we’re looking for is sunny, warm afternoons, and clear, cold nights,” said Evan Fisher, the founder of <a target="_blank" rel="noopener noreferrer nofollow" href="http://ExploreFall.com">ExploreFall.com</a>. Too much drought or rain can vastly impact the colors produced by the trees. &nbsp;&nbsp;Heat can induce stress on the trees and allow them to show color early. Fisher said maples are susceptible to stress, such as a warm summer, like many along the Eastern Seaboard have seen in the 2024 summer season. &nbsp;“The hardest part of predicting fall color is accounting for the extremes.” Fisher elaborated. “[Drought] that can do crazy things to the fall color. If you have a little bit of drought it may delay the color. If you have a lot of drought, it may accelerate it. But we don’t really know exactly where that line is exactly in between. And sometimes the same goes for really moist conditions.” &nbsp;Another important factor for forecasting foliage is the amount of daylight too. “I like to say that daylight opens the door for fall colors. Once the days get short enough and the temperatures are cool enough, we start to see the colors progress,” Fisher said.&nbsp;You can learn more about forecasting fall colors below:&nbsp;<div data-youtube-video=""><iframe width="640" height="480" allowfullscreen="false" src="https://www.youtube.com/embed/GyZbO8Rh3Ug" start="0"></iframe></div>WHY ARE THEY DIFFERENT COLORS: &nbsp;The color each tree presents depends on what’s present in the leaves. According to the State University of New York’s College of Environmental Science and Forestry, xanthophyll and carotenes are already present in leaves as the green chlorophyll fades away. These pigments give leaves yellow and orange coloring, similar to how they color other plants such as carrots.&nbsp;Other chemical reactions can happen at the same time as the fading green color which produces anthocyanin pigments, which give leaves a reddish and purplish color. The Forestry Services of Scotland says if temperatures stay above freezing, more of these anthocyanin pigments are produced. If autumn remains sunny and dry, even more trees will begin to produce pigments to give even more red color. The process is slow though, which is why you sometimes see trees with a mix of greens, yellows, and reds all at once.&nbsp;WHY DO LEAVES DROP:&nbsp;In the spring, trees create little tubules between the leaves and the branches to transport nutrients back and forth between the leaves. As the fall creeps in, the tree begins producing a hormone that builds up a waxy layer between the leaf and the branch that reduces nutrient transportation. Eventually the leaf will be weak enough to be carried away by the wind, rain, or snow, said Michael Davidson on his Molecular Expressions website via Florida State University. &nbsp;By dropping their leaves, deciduous trees will spend less energy through the winter and converse moisture throughout their systems. The dropping of their leaves also prevents external stress that can occur when heavy snow weighs down a tree’s branches. &nbsp;

Our weather seasons are broken up a little bit differently than the astronomical seasons. In astronomy, we look to Sunday, September 22, 2024 as the official start of fall. The Autumnal Equinox will happen around 8 a.m. ET that Sunday, when the sun's rays move directly over the Equator. It's a moment in time when Earth gets equal day and night, 12 hours of each.<img src="https://media.weathernationtv.com/app/uploads/2024/08/Screenshot 2024-08-31 121559-1725128816380.png">The first day of Meteorological Fall was September 1, and continues through November 30 when Meteorological Fall ends. Our weather seasons are split into even three-month periods for easier record keeping.<img src="https://media.weathernationtv.com/app/uploads/2024/09/Screenshot 2024-09-02 203921-1725331171022.jpg">So, welcome to Fall! The weather outlook from the Climate Prediction Center shows much of the Lower 48 having higher chances of remaining warmer-than-average during September, October, and November.<img src="https://media.weathernationtv.com/app/uploads/2024/09/Screenshot 2024-09-02 204030-1725331248812.jpg">This does not mean it won't get chilly or cool. Short-term cold weather patterns will still be possible. But when the three-month period is summed up, it will likely be warmer-than-average.<img src="https://media.weathernationtv.com/app/uploads/2024/09/Screenshot 2024-09-02 204038-1725331302461.jpg">The outlook for September, October, and November calls for drier-than-average weather for parts of the Desert Southwest, Four Corners, Southern/Central Plains, and lower Pacific Coast. The Northwest coast and East Coasts will be wetter-than-average.

It's Meteorological Fall! Here's the Outlook

A fresh couple of inches of snow fell across the high terrain of the Colorado Rockies late Wednesday night and early Thursday morning from September 4-5, 2024. It resulted in outstanding pictures of the Rockies, now white with snow above 10,000 feet!<img src="https://media.weathernationtv.com/app/uploads/2024/09/copper pic 2 09-05-24-1725575707640.png">Copper Mountain, about an hour and a half west of Denver, had a dusting of snow at the top of its ski lifts early Thursday.

While the low elevations, such as Denver, drop into the 50's at night, the high country drops to the 30's and 20's during the overnights. A cold front moving through Colorado brought enough moisture to provide this light snow above 10,000 feet.<img src="https://media.weathernationtv.com/app/uploads/2024/09/1-1725591460700.png">Heavy snowfall rates were reported at Berthoud Pass, CO (about 12,000 feet) late Wednesday. The total snowfall was not heavy, but the rate was briefly intense. The average first snowfall occurs in September in the Rocky Mountain region of the West.<img src="https://media.weathernationtv.com/app/uploads/2024/09/Screenshot 2024-09-05 164020-1725576027495.png"> September can provide some light snow accumulation atop New England at Mount Washington and the nearby White Mountains. As we get into October, the first snow becomes more likely in some of the lower elevations farther north.No additional snow is expected in Colorado in the near-term, but this gets some of us excited for the upcoming ski and snowboard season!

An active pattern is set to return to parts of the northwest over the next few days. High pressure will bring the heat, but an incoming trough will kick up rain chances AND fire concerns. Fire and rain? How is that possible? <img src="https://media.weathernationtv.com/app/uploads/2024/09/West Red Flag-1725375696960.png">DRY THUNDERSTORMS! Some of these high-based storms that develop bring rain to the area, however, the rain doesn't always make it to the surface if there is a dry airmass at the surface. So, the storm can bring the lightning and wind but not the rain, which causes the fire concern. If the surface fuels are dry, and lightning strikes the wind can spread that blaze very quickly.Air quality alerts are also in place for the region from fires currently across the Northwest. This means particulate matter may cause issues for sensitive groups. These groups which include, those with respiratory or heart disease, the elderly, and children should limit prolonged exertion. <img src="https://media.weathernationtv.com/app/uploads/2024/09/Fire and Smoke -1725376027015.png">As our next system moves onshore, some more rain chances will accompany it.

Taban Sharifi grew up in Southern California between Los Angeles and San Diego. She is a Certified Broadcast Meteorologist (CBM) with the American Meteorological Society (AMS). She has a B.S. in Atmospheric, Oceanic, and Environmental Sciences with a minor in Environmental Systems and Society from the University of California, Los Angeles (UCLA). Go Bruins! While in school, Taban was a meteorology intern with NBC LA. There she helped forecast daily weather for the greater Los Angeles region and created a playbook to deploy weather sensors for NBC owned-and-operated stations across the country. Her first on-air job took her to San Angelo, Texas, where she was a morning meteorologist and co-anchor. Working in West Texas gave her knowledge and experience covering severe storms. From there, she moved to Palm Springs, California. People think forecasting in California is sunshine all the time, but with temperatures in the 120’s, wildfires, damaging winds, floodings, and earthquakes, the forecasting kept her very busy! She also worked there as a general assignment reporter and told community stories. Taban is excited for the challenge and opportunity to forecast nationally with WeatherNation. She also looks forward to exploring all that Colorado has to offer!

Rob grew up in South Florida, where daily afternoon storms and hurricanes piqued his interest in meteorology early on. That interest was fostered by his teachers and his father, who one time brought him onto the roof of their home to watch a funnel cloud move through the Everglades several miles away. Years of filmmaking and tv production in high school gradually pushed him toward broadcast meteorology at Florida State University, where he joined and eventually led the student run daily weather show. After graduating with a Bachelors of Science in Meteorology, he began his career at KESQ in Palm Springs, California before heading to KFSN in Fresno and WLOS in Asheville, North Carolina. He has covered a diverse array of extreme weather events, including haboobs and flash flooding in the desert, extreme snow in the Sierra, hurricanes, and Appalachian ice storms. He also enjoys telling stories and reporting about weather issues.

Severe Storm Threat Continues in the Midwest

August 29th is the anniversary of the most notorious and costliest hurricane in U.S. history, Katrina. Sixteen years to the day, Hurricane Ida hit Louisiana in 2021. Both made landfall along the Gulf Coast, devastating communities in Louisiana and Mississippi with storm surge and flooding.&nbsp;&nbsp;<h2>Katrina&nbsp;</h2>On Wednesday August 24, 2005 tropical depression 12 strengthened into tropical storm Katrina and hit the Florida Keys as a CAT 1 Hurricane on Thursday. During its 6 hours in the sunshine state, Katrina left $600M in damage and was responsible for 14 deaths.&nbsp;&nbsp;Katrina then reemerged into the Gulf, weakened from time over land as a tropical storm. But that didn’t last long, by Saturday Katrina was a MAJOR hurricane, a powerful CAT 3 and then rapidly intensified into a CAT 5 with winds of 175 mph.&nbsp;&nbsp;Just before landfall Katrina weakened to a CAT 3 with sustained winds of 125 mph. The rapid weakening was likely due to an eyewall replacement cycle just ahead of landfall. The first landfall was in SE Louisiana before a second landfall along the Mississippi Gulf Coast.&nbsp;&nbsp;Despite weakening, Katrina’s shear size created huge waves and wide reaching impacts. Just offshore from southern Alabama a wave of 55’ was measured as Katrina came ashore.&nbsp;The storm surge from where Katrina made landfall was nearly impossible to determine due to the damage, but it is estimated to have been 24 to 28 ft along the Mississippi coast across a swath about 20 miles wide, centered around Bay St. Louis.&nbsp;&nbsp;The city of New Orleans was evacuated the day before Katrina hit and many people could not get out in time, and the “Superdome” became a shelter for nearly 20,000 people. Officials weren’t ready for the influx of people – they only brought supplies for 15k people for 3 days.&nbsp;&nbsp;The levees in the city of New Orleans were breached by a surge of 15-19 feet, leaving 80% of the city underwater. Over 10 feet of water covered St. Bernard Parish, covering rooftops. In the lower ninth ward 6 to 8 feet of water stranded people in their homes. Winds gusted up to 100 mph in the city.&nbsp;&nbsp;Sadly, over 2,000 people lost their lives during Hurricane Katrina and its aftermath. Katrina is the third deadliest hurricane in U.S. History, after the 1900 Galveston Hurricane and 1928 Lake Okeechobee Hurricane. It remains the costliest natural disaster in U.S. History – producing $193.8B in damages (2023 cost adjusted).&nbsp;&nbsp;<div data-youtube-video=""><iframe width="640" height="480" allowfullscreen="false" src="https://www.youtube.com/embed/5MVrL7z5hoI" start="0"></iframe></div><h2>Ida&nbsp;</h2>The first landfall of Ida was in Port Fourchon, Louisiana at 11:55 AM CDT on August 29th. Winds were sustained at 150 mph and pressure was down to 930 mb. Ida tied Hurricane Laura from the previous year for the strongest storm on record to hit the state.&nbsp;&nbsp;The second landfall occurred at 2:00 PM CST near Galliano, Louisiana as a category 4 storm with sustained winds of 145 mph and pressure of 934 mb.&nbsp;24 tornadoes touched down in Gulf Coast states and into the South as Ida was under tropical characterization. 34 people in Gulf Coast states lost their lives because of Ida, most in post-storm fatalities of heat exhaustion and CO2 poisoning from generators.&nbsp;&nbsp;After devastating the gulf coast, Ida then traveled north through the Appalachians, eventually becoming post tropical over West Virginia on September 1st. Despite the downgrade in status, Ida brought deadly flash flooding and damaging tornadoes along the I-95 corridor from Maryland to New England.&nbsp;&nbsp;An EF-2 tornado touched down near Annapolis and there were 7 confirmed tornadoes in Eastern Pennsylvania &amp; New Jersey. An EF-3 was on the ground for more than 12 miles in Mullica Hill, NJ, the strongest in the state in 31 years.&nbsp;&nbsp;More widespread than the tornadoes was the flooding – made worse by previous tropical systems Henri and Fred which saturated the soils in the Northeast.&nbsp;&nbsp;Flash flooding on the night of September 1st turned streets around the NYC metro into rivers – 4 separate flash flood emergencies were issued by the NWS as basement apartments flooded and subway systems. Sadly, 49 people lost their lives in the Northeast as a result of Ida, 48 as a result of flooding.&nbsp;Ida was the costliest disaster of 2021, with over $60B in damages.&nbsp;&nbsp;<div data-youtube-video=""><iframe width="640" height="480" allowfullscreen="false" src="https://www.youtube.com/embed/SoIIU-YngnM" start="0"></iframe></div>

<h2>Pacific</h2>As Hone continues to weaken and push away from Hawaii, we look back to the East where two more storms are still churning in the Eastern Pacific. (Once) Hurricane Gilma has decreased in strength to a tropical storm and will continue weakening.The latest forecast cone from the National Hurricane Center has Hurricane Gilma approaching Hawaii as a tropical depression after some weakening over the next day as it runs into drier air, and should dissipate to a remnant low as it approaches Hawaii. <img src="https://media.weathernationtv.com/app/uploads/2024/08/8-29 Gilma-1724937741873.png">As for Hector, we say goodbye. This system has decreased to a remnant low, out in the Pacific as the fish storm it was! Hector will not be impacting Hawaii. <img src="https://media.weathernationtv.com/app/uploads/2024/08/Hector-1724938623108.png"><h2>Atlantic</h2>The Atlantic is starting to slowly ramp back up as it seems to have forgotten that we're nearing the peak of hurricane season. While nothing is even close to concrete, the National Hurricane Center highlighted an area in the central Atlantic with a 40% chance of development in the next 7 days. <img src="https://media.weathernationtv.com/app/uploads/2024/08/Tropical Outlook-1724938291566.png">
