<h3>KEY MESSAGES:</h3><ul><li>Catastrophic and life-threatening flash flooding with numerous landslides for Jamaica, Haiti, the Dominican Republic, and Cuba</li><li>Devastating winds for Jamaica</li><li>Life-threatening storm surge and damaging waves for Jamaica and Cuba</li><li>Watching for the Bahamas and Turks and Caicos Tue-Wed</li></ul>All eyes are on the Caribbean as we are now tracking the 13th named storm of the 2025 season - Melissa. In fact, we've been tracking Melissa and its origins as a tropical wave for more than a week now, and we could be watching it for another week still! Melissa has rapidly intensified into a Category 5 hurricane, with sustained winds of 160 mph, a pressure of 913 mb, and is&nbsp;slowly moving west at 3 mph.Melissa will hardly move, bringing catastrophic and life-threatening rainfall and mudslides to Jamaica, Hispaniola, and Cuba. Over a couple of feet of rain is possible for Hispaniola (Haiti &amp; the DR) and Jamaica.<img src="https://media.weathernationtv.com/app/uploads/2025/10/Web2-1761557474776.png">Melissa's lack of movement is due to its position between two ridges of high pressure in the mid-levels, while in the upper-levels is keeping Melissa in the Caribbean for now before picking up some steam next week. The National Hurricane Center has relayed some intense key messages for Hurricane Melissa, warning of life-threatening and catastrophic flash flooding and landslides in Jamaica and southern Hispaniola through mid-week.<div class="twitter-tweet" style="display: flex; justify-content: center" data-twitt-post-id="1982557802800574545" src="https://x.com/NHC_Atlantic/status/1982557802800574545"></div>The latest forecast cone from the National Hurricane Center shows little forward movement over the next few days. Slow westward motion is expected through Monday morning, before turning north and northeast on Monday and Tuesday. Melissa is expected to move near or over Jamaica on Tuesday, across southeastern Cuba Tuesday night, and across the southeastern Bahamas on Wednesday, according to the NHC.<img src="https://media.weathernationtv.com/app/uploads/2025/10/Web3-1761557529544.png">Hurricane warnings (in red) have been issued for Cuba, Jamaica, with a few tropical storm warnings also in effect for portions of Haiti and Cuba. A warning is typically issued 36 hours before the anticipated first occurrence of these conditions.<img src="https://media.weathernationtv.com/app/uploads/2025/10/Web5-1761557563856.png">Sea surface temperatures remain warm across the Caribbean, providing ample fuel if the wave can find a pocket of lower shear and increased moisture.<img src="https://media.weathernationtv.com/app/uploads/2025/10/Screenshot 2025-10-23 060209-1761220940859.png">As many of our recently back-loaded tropical seasons have reminded us, October is not the month to let your guard down.<img src="https://media.weathernationtv.com/app/uploads/2025/10/Screenshot 2025-10-15 103336-1760546429287.png">Tune into WeatherNation for the top weather headlines for more on the tropics.

GAUTIER, MS - Earlier Sunday morning, tornado warnings swept through the Gulf Coast, and this person was caught in the debris of the tornado in Mississippi. The severe threat continues through tonight across the Gulf Coast as this frontal boundary keeps moving through.<div class="twitter-tweet" style="display: flex; justify-content: center" data-twitt-post-id="1982498399602786785" src="https://x.com/WeatherNation/status/1982498399602786785"></div>According to the National Weather Service in New Orleans, a survey team will be heading out on Monday morning to survey the damage that Sunday morning's storms brought. The NWS has also encouraged anyone in the region to send over their reports to help with their surveys as well.<div class="twitter-tweet" style="display: flex; justify-content: center" data-twitt-post-id="1982508518684209425" src="https://x.com/NWSNewOrleans/status/1982508518684209425"></div><img src="https://media.weathernationtv.com/app/uploads/2025/10/Screenshot 2025-10-26 163627-1761518716166.png">Most of the storms from Sunday sat along a warm front and remained as supercells. Through the overnight hours, storms are expected to cluster together, lessening the tornado threat but maintaining the wind, hail, and heavy rain threat into Florida.<video src="https://media.weathernationtv.com/app/uploads/2025/10/10-26 east-1761531893312.mp4" controls="true" width="100%"></video>Heavy rain is also going to be a concern along the system, and with another batch of rain moving in by late Tuesday, the flood threat will continue into the work week as well.<img src="https://media.weathernationtv.com/app/uploads/2025/10/Screenshot 2025-10-26 202400-1761531846617.png">For more details on how this rain may influence your forecast temperatures, be sure to join us at :10 past the hour, where we detail your east regional forecast.

WEST - A series of atmospheric rivers has been responsible for wet, windy, and snowy weather in the northwestern U.S. This moisture continues to push inland through Monday. Another front is likely to move onshore as we head into Monday and Tuesday, but will mostly be focused on the state of Washington.<video src="https://media.weathernationtv.com/app/uploads/2025/10/2025-10-27 04-58-13-1761562723943.mp4" controls="true" width="100%"></video>Winter weather alerts remain in place for the snowfall in the mountains we're expecting from this. Between 4-8" of snowfall is likely through Monday.<img src="https://media.weathernationtv.com/app/uploads/2025/10/Web4-1761562533948.png">Another possible dump of snow could come in with the next front, which could lead to snow totals measured by feet in the mountains through mid-week.<img src="https://media.weathernationtv.com/app/uploads/2025/10/Web1-1761562637012.png">Be sure to join us at:50 past the hour for more details during your west regional forecast.

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!

GREAT LAKES - A large trough has been moving over the northern U.S. since early this week, bringing along with it gusty winds, scattered showers, and cooler temperatures.As the upper-level trough and surface front move over the Great Lakes, they'll continue to usher in cooler air above warmer sea surface temperatures. The contrast between the two can enhance lake-effect showers. It's not quite cold enough for lake-effect snow with this system. These off-and-on showers, which have been dragging over the Great Lakes, will begin to wind down as we head into the weekend.With cold temperatures also being ushered in, temperatures tonight will drop into the 30s and 40s from the Great Lakes down to the Carolinas.<img src="https://media.weathernationtv.com/app/uploads/2025/10/Screenshot 2025-10-24 141852-1761337221612.png"><img src="https://media.weathernationtv.com/app/uploads/2025/10/Screenshot 2025-10-24 142002-1761337234549.png">As a result, Frost Advisories and Freeze Warnings have been issued again for Saturday morning.<img src="https://media.weathernationtv.com/app/uploads/2025/10/Screenshot 2025-10-24 141435-1761337300431.png">For more details on what the forecast looks like once this low moves out, be sure to join us LIVE on WeatherNation, which streams 24/7.

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.

Ready for another La Niña winter? NOAA quietly released it's outlook for the upcoming winter season on Thursday, sans press conference since the government shutdown continues. The press conference has been rescheduled to November but the outlook is still ready for us to digest. As a reminder, these outlooks are for the overall three month pattern and do not serve to predict seasonal snowfall totals or bursts of cold/warmth that are likely to impact areas highlighted with the seemingly opposite outlook. The National Weather Service released the following video showcasing the newly released outlooks for temperature, precipitation, and drought from December through February.<div class="twitter-tweet" style="display: flex; justify-content: center" data-twitt-post-id="1978839667907744157" src="https://x.com/NWS/status/1978839667907744157"></div><h1>Temperature</h1>Above average temperatures are favored across the southern tier of the United States, while below average temperatures are favored across the Upper-Midwest and Northwest. <img src="https://media.weathernationtv.com/app/uploads/2025/10/Screenshot 2025-10-17 065848-1760706897085.png"><h1>Precipitation</h1> As the jetstream is likely to remain more active across the northern tier of the country, allowing for cooler air, it should also allow for more storms to track through these areas. As such, above average precipitation is favored from the Northwest through the Great Lakes, while drier than average conditions are expected from Southern California through Florida and the Carolinas. <img src="https://media.weathernationtv.com/app/uploads/2025/10/Screenshot 2025-10-17 065852-1760706026499.png"><h1>Influences</h1>In case you missed it, <a target="_blank" rel="noopener noreferrer nofollow" href="https://www.weathernationtv.com/news/la-nina-advisory-issued-how-this-could-affect-the-winter-season">a La Niña Advisory was issued last week</a> as these conditions were observed in the equatorial Pacific west of South America. La Niña is expected to persist through winter, which is one of the primary reasons the winter outlook favors the areas it does. La Niña patterns vary greatly from year to year, depending on the strength of La Niña and the phase of the PDO (Pacific Decadal Oscillation). The graphic below shows the typical pattern of the Pacific and Polar jets during a La Niña winter, which usher in cooler and wet air masses. <img src="https://media.weathernationtv.com/app/uploads/2025/10/Screenshot 2025-10-17 065856-1760707324994.png">There is lower confidence that La Niña continues through the late winter and early spring (graphic below), which could throw a wrench in the seasonal forecast. <img src="https://media.weathernationtv.com/app/uploads/2025/10/Screenshot 2025-10-17 073303-1760707994646.png">ENSO (El Niño &amp; southern Osciallation) neutral conditions have a less obvious pattern influence, but wetter conditions can develop farther south than during La Niña. What's the takeaway? Be prepared for anything this winter! We'll always keep you up to date on air and online.<img src="https://media.weathernationtv.com/app/uploads/2025/10/Screenshot 2025-10-17 073307-1760708002217.png">

NOAA's <a href="https://www.cpc.ncep.noaa.gov/">Climate Prediction Center</a> issued their <a href="https://www.cpc.ncep.noaa.gov/products/predictions/long_range/lead14/" target="_blank" rel="noopener">outlook for March</a> late last week, with a colder month expected ahead for many areas of the nation. Below average temperatures are forecast from the Northeast southward through the Tennessee Valley and Southern Plains to the Gulf of Mexico. Warmer than normal temperatures are favored in the Southwest.

It may be a quieter end to the snow season in the Great Lakes, Central Plains and along the West Coast. That's where drier than normal weather is in the forecast. A wetter than average month is expected along the Gulf of Mexico and Florida.
