A tropical disturbance in the eastern Atlantic has an 80% chance of becoming a tropical depression within the next seven days. The area of disorganized showers and thunderstorms southwest of the Cabo Verde islands is drawing more attention, as conditions become increasingly favorable for storm development. The National Hurricane Center (NHC) assigned the tropical wave, as Invest 91L, on Thursday. According to the NHC, this broad area of low pressure is moving slowly west-northwest at a speed of around 5-10 mph.<img src="https://media.weathernationtv.com/app/uploads/2025/09/Screenshot 2025-09-04 053322-1756985610501.png">If development continues, Invest-91L would be classified as&nbsp;Tropical Depression Seven&nbsp;and could be named&nbsp;Tropical Storm Gabrielle by this weekend or early next week. Models are giving a strong indication that the system could gradually strengthen as it moves across warm waters in the central Atlantic.<video src="https://media.weathernationtv.com/app/uploads/2025/09/2025-09-04 10-16-10-1757002681627.mp4" controls="true" width="100%"></video>However, as of now, it is still relatively far out to see where it could be headed. Different models have vastly different paths at this time. One model shows the storm remaining weak and drifting westward toward the Caribbean. Others depict it strengthening more rapidly and curving northward, influenced by a strong dip in the jet stream expected over the eastern United States later this week. The outcome will largely depend on how organized the system becomes in the coming days. Weaker storms are typically less responsive to steering currents, while more developed systems can be more accurately predicted.<video src="https://media.weathernationtv.com/app/uploads/2025/09/2025-09-04 05-33-43-1756985721420.mp4" controls="true" width="100%"></video>Do not let your guard down. September is historically the peak of hurricane season, and ocean conditions remain favorable for additional development. However, the NHC urges residents along the Atlantic basin to monitor updates closely.<img src="https://media.weathernationtv.com/app/uploads/2025/09/Screenshot 2025-09-04 053605-1756985781092.png">As always, preparedness is key. Whether or not this particular system develops into a named storm, it serves as a reminder that the Atlantic remains active and that the window for tropical threats is far from closed.

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.

We're always keeping a close eye on all things tropical here at WeatherNation! <a target="_blank" rel="noopener noreferrer nofollow" href="https://www.weathernationtv.com/news/tropical-depression-could-develop-in-atlantic-late-week">The Atlantic has a tropical wave moving through the MDR</a>, while things are active with two named storms in the Eastern Pacific. <h1>EASTERN PACIFIC</h1>Hurricane Kiko continues to churn to the West after strengthening quickly to a strong category 4 hurricane. It's expected to gradually weaken through early next week as it approaches the Hawaiian Islands.<img src="https://media.weathernationtv.com/app/uploads/2025/09/Screenshot 2025-09-04 045821-1756983818640.png">The mid-range forecast brings Kiko close to the Hawaiian islands. Residents should monitor this forecast closely over the next day or two, making preparations as necessary over the next several days. Gather non-perishable food items, water for each person in your home that will last for several days (1 gallon per person per day), and check your hurricane preparedness plan. Additional preparation may be necessary this weekend. <img src="https://media.weathernationtv.com/app/uploads/2025/09/Screenshot 2025-09-04 045831-1756983824384.png">Hurricane Lorena continues to churn offshore of the Baja Peninsula where it's expected to slow down and slowly weaken as it moves inland this weekend. <img src="https://media.weathernationtv.com/app/uploads/2025/09/Screenshot 2025-09-03 205838-1756954724753.png">Most of Lorena's impacts will be in Mexico, but some of that the moisture gets siphoned off and ends up around the 4-Corners <a target="_blank" rel="noopener noreferrer nofollow" href="https://www.weathernationtv.com/news/moisture-from-hurricane-lorena-hits-the-southwest-this-weekend">where it creates flood potential</a> into the weekend.<img src="https://media.weathernationtv.com/app/uploads/2025/09/Screenshot 2025-09-04 052155-1756984934407.png">

Hurricane Kiko Tracking Toward Hawaii, Lorena Near Baja Creating SW Storms

Moisture from Hurricane Lorena will be pulled to the northeast across the lower Four Corners and portions of Texas through the weekend. Flash flooding is the primary concern, though a few strong thunderstorms are possible along with gusty winds that could create blowing dust.<img src="https://media.weathernationtv.com/app/uploads/2025/09/Screenshot 2025-09-04 050407-1756987782706.png">Lorena is expected to weaken gradually to a remnant low this weekend as it slows down, and nearly stalls, over the central Baja Peninsula. This means the SW U.S. shouldn't expect wind impacts from Lorena, just the potential for heavy rain.<img src="https://media.weathernationtv.com/app/uploads/2025/09/Screenshot 2025-09-04 061408-1756988059024.png">Flood watches have been issued from Thursday to Saturday for portions of California and Arizona. Flood potential is expected to gradually shift east to Texas into the weekend.<h1>Forecast</h1>Heavy downpours are expected to quickly form and fall into the afternoon hours on Thursday, with additional storms in the afternoon on Friday. By Saturday, moisture gets pulled far enough to the south and east that flood chances should taper off farther west and north, such as the Sierra or the deserts of California.<video src="https://media.weathernationtv.com/app/uploads/2025/09/2025-09-04 06-17-43-1756988293229.mp4" controls="true" width="100%"></video>Pockets of 3-4 inches of rain are possible, especially around the Four Corners. Flood potential will stretch from the Sierra through the Rockies.<img src="https://media.weathernationtv.com/app/uploads/2025/09/Screenshot 2025-09-04 061528-1756988135386.png">Stay with WeatherNation for the latest.

A hot dome of high pressure continues to bake parts of California and the Pacific Northwest with record heat. On Wednesday, Ellensburg, WA, tied a record high.<img src="https://media.weathernationtv.com/app/uploads/2025/09/Screenshot 2025-09-03 211616-1756955813176.png"><h2>Heat Alerts</h2>Heat advisories remain in place for the western U.S. For the northwest, heat advisories last through Thursday. Hot temperatures will increase the risk of heat-related illnesses, so be sure to keep cool and hydrated. Extreme heat warnings also remain in place for Oregon and interior Washington.<img src="https://media.weathernationtv.com/app/uploads/2025/09/Screenshot 2025-09-04 095142-1757001113784.png"><h2>Temperatures</h2>Temperatures will be pushing 15° above average across western Oregon, including the Willamette Valley. Even more anomalous, temperatures in the Inland NW will rise up 20° above average, as locales such as Spokane, WA, will be feeling triple-digit heat.<img src="https://media.weathernationtv.com/app/uploads/2025/09/Screenshot 2025-09-04 095208-1757001139303.png">Here are some good tips if you're unfortunately dealing with the heat without the benefits of air conditioning.<img src="https://media.weathernationtv.com/app/uploads/2025/08/Screenshot 2025-08-29 174031-1756511416611.png">

Late Summer Heatwave Out West

NORTHERN PLAINS - A series of cold fronts will move through the Midwest to the northeast over the next several days. First, a cold front that moved down from Canada on Tuesday will continue to bring strong storms, gusty winds, and cooler temperatures across the Northern tier of the country through the end of the week. Then, this weekend, a second cold front arrives from Canada to reinforce the cooler air.<video src="https://media.weathernationtv.com/app/uploads/2025/09/09-03 RNC STORMS-1756955636998.mp4" controls="true" width="100%"></video><h2>Temperatures</h2>Behind the front, temperatures will drop significantly as winds shift to the north.<img src="https://media.weathernationtv.com/app/uploads/2025/09/Screenshot 2025-09-02 160633-1756850797164.png">For many areas, this will be the coolest air since spring, even cooler than the most recent bout of chilly temperatures. Morning lows are expected to dip into the 40s on Thursday, Friday, and Saturday, with Friday likely to be the coldest morning across the Northern Plains.<img src="https://media.weathernationtv.com/app/uploads/2025/09/Screenshot 2025-09-02 121321-1756836809221.png">Long-range trends keep the eastern U.S. with high confidence in temperatures being below average. Fall is here! If you're curious when the Autumnal Equinox arrives, also known as astronomical fall, this year it is on September 22nd.<img src="https://media.weathernationtv.com/app/uploads/2025/09/Screenshot 2025-09-02 160654-1756850818685.png">

PHILADELPHIA - As the Philadelphia Eagles celebrate their championship on Thursday, Mother Nature will try to provide the fireworks. A powerful cold front is bringing record cold temperatures to those in the Midwest and Great Lakes will pivot eastward on Thursday. That could mean trouble for some outdoor activities. According to some local reports, the Eagles won't even be on the field for the ceremony. But with plenty of fans in the stands, we thought we'd take a look at the forecast for the afternoon.<h1><img src="https://media.weathernationtv.com/app/uploads/2025/09/Screenshot 2025-09-03 111753-1756919960734.png">LIGHT THE FUSE</h1>As our cold front drops in, it will fire up a line of storms, that will be capable of producing gusty winds along the leading edge. Unfortunately for any ceremony-goers, it looks like the 5-8 PM ET window might be the easiest one for the storms to fit into. It doesn't have a ton of juice to work with, but there will be just enough combined with the strength of the front to keep the severe potential on the table.<img src="https://media.weathernationtv.com/app/uploads/2025/09/Screenshot 2025-09-03 111657-1756920009454.png">The Storm Prediction Center is already monitoring the area for the threat of severe storms, with a wide area capable of picking up damaging winds. With plenty of lightweight objects to toss around, from the celebration to tailgating, higher winds would be unwelcome. <h1>Timing</h1>Storms will lean toward the evening hours, making a close call with the ceremonies. <video src="https://media.weathernationtv.com/app/uploads/2025/09/2025-09-03 11-52-00-1756922059738.mp4" controls="true" width="100%"></video><h1>FINE THEN LET'S TRY BRAZIL</h1>Since the weather doesn't want to cooperate stateside, we get to try again Friday night with the runner-ups down in Sao Paulo. Couldn't have drawn it up any better. Chef's kiss, pun intended. <img src="https://media.weathernationtv.com/app/uploads/2025/09/Screenshot 2025-09-03 115619-1756922452985.png">

Until the past week, has anyone been impressed by the monsoon season this year?Compared to normal, many locations that see most of their rain this time of the year have been left high and dry. All of that dry time has played a pivotal role in the wildfire threat that is seemingly never-ending. This has been the second driest start to a calendar year in the city of Tucson!<img src="https://media.weathernationtv.com/app/uploads/2025/09/Screenshot 2025-09-01 104436-1756745109335.png">While some headline-hooking haboobs have brought desert storms to the forefront, many are still pretty far behind, rainfall-wise. However, this week the same high pressure that is baking the Pacific Northwest will also open the door to fling a little moisture westward. Some of this Monsoon moisture will curl around an area of high pressure and move through Southern California.<img src="https://media.weathernationtv.com/app/uploads/2025/09/Screenshot 2025-09-01 104956-1756745422822.png">This moisture leaves the southwest under an excessive rainfall outlook for the next 5 days!<img src="https://media.weathernationtv.com/app/uploads/2025/09/Web 9-1756811779052.png">Related articles: <a target="_blank" rel="noopener noreferrer nofollow" href="https://www.weathernationtv.com/news/haboob-blows-through-phoenix-monday-afternoon">Haboob Blows Through Phoenix</a> <a target="_blank" rel="noopener noreferrer nofollow" href="https://www.weathernationtv.com/news/heatwave-looming-for-the-northwest">Late Summer Heatwave</a>That added moisture will help bolster rain chances as far southwest as southern California!

A Flash Flood Emergency was in effect for Ellicott City, Maryland, Sunday evening after extreme flooding was seen throughout the city.

The extreme flooding prompted multiple water rescues Sunday evening and there was a report of one person missing within the flooding early Monday morning.

https://www.facebook.com/WeatherNation/videos/10156534196104874/

&nbsp;

Rushing floodwaters collapsed building within the city, according to reports.

Officials urged all citizens nearby to seek higher ground immediately as another round of flood waters were imminent.

https://www.facebook.com/WeatherNation/videos/10156533379604874/

The downtown area is experiencing rushing flood water taking everything in it's path down Main Street. Officials are now reporting the flood water reaching the second story of some of the downtown buildings.  Many are saying this is already worse than the "1,000 year flood" that occurred in July of 2016.

On Sunday evening, the National Weather Service office in Baltimore said that the Hudson gauge situated on the Hudson Branch is  currently 3 feet over flood stage and the worst is yet to come.

<img class="alignnone wp-image-91891 " src="https://media.weathernationtv.com/app/uploads/2018/05/ezgif.com-video-to-gif-24.gif" alt="" width="792" height="446" />

The flooding occurred due to a stationary front that remained draped across the area. Slow moving showers and storms continued to train over that area.
