<a target="_blank" rel="noopener noreferrer nofollow" href="https://www.weathernationtv.com/news/pacific-tropics-active">Hurricane Polo is moving north</a>, set to make landfall in the Baja California of Mexico Today. As it pushes inland into Tuesday, its moisture will funnel into the United States. As a trough of low pressure digs across the West and interacts with that moisture, the south central U.S. will see a multi-day flood threat develop. While they need the rain, drought conditions and dry ground will initially exacerbate the flood threat.<img src="https://media.weathernationtv.com/app/uploads/2026/09/Screenshot 2026-09-28 085902-1790607553539.png">RELATED ARTICLE: <a target="_blank" rel="noopener noreferrer nofollow" href="https://www.weathernationtv.com/news/another-round-of-flooding-possible-for-the-southwest-next-week">Polo Prompts Extreme Flood Threat for the Southwest</a><h1>TIMING</h1>Onshore flow from the Gulf will all for a handful of scattered storms to pop up Monday and Tuesday. Late Tuesday into Wednesday, storms from the southwest will begin moving into the region and bring heavy rain. The upper level trough will help enhance lift and drag a slow moving boundary through Texas through Thursday. As Pacific and Gulf Moisture feed the system, rainfall becomes more plentiful and efficient both days. Storms will linger on Friday, before the system slowly moves east.<video src="https://media.weathernationtv.com/app/uploads/2026/09/txbams-1790607686464.mp4" controls="true" width="100%"></video>Not surprising, with such a dynamic system, we could see a threat for severe storms on Wednesday. The Storm Prediction Center has already issued a slight risk for damaging wind and hail potential.<img src="https://media.weathernationtv.com/app/uploads/2026/09/Screenshot 2026-09-28 090451-1790607924932.png"><h1>RAIN &amp; FLOOD THREAT</h1>Rainfall totals through Friday will easily hit the 3-5" range for much of Central Texas and Oklahoma. Isolated totals could reach 6-8". We expect Flash Flood Watches to be issued in the region very soon.<img src="https://media.weathernationtv.com/app/uploads/2026/09/Screenshot 2026-09-28 084930-1790608243245.png">Monday and Tuesday, the greatest chance for dangerous flash flooding will be from the Desert Southwest into the Panhandle region. As the front marches east, so does the Moderate Risk from the Weather Prediction Center. Interests up and down the I-35 corridor should pay close attention to the forecast and current conditions through midweek. That's where the threat settles for Wednesday, Thursday and Friday.<video src="https://media.weathernationtv.com/app/uploads/2026/09/txwpc-1790608081143.mp4" controls="true" width="100%"></video><h1>DROUGHT</h1>Extreme summer heat and lack of precipitation has pushed parts of the south central U.S. into Exceptional Drought (level 4 out of 4).

These conditions are important, because they will impact the way the ground handles the incoming rainfall. Think of it like a dry sponge. When you turn on the faucet, the water initially runs off. It takes a bit for it to start to absorb. If the rain runs off of the hard ground, it goes into homes and businesses before being absorbed.<img src="https://media.weathernationtv.com/app/uploads/2026/09/Screenshot 2026-09-28 091809-1790608707679.png">

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!

A Nor'easter...in September? While most people think of winter when it comes to these intense coastal storms, they can happen in the fall. The impacts will only be a little different, mainly with heavy rain instead of snow, but coastal flooding, huge surf, and strong winds will continue to create significant hazards.<div class="twitter-tweet" style="display: flex; justify-content: center" data-twitt-post-id="2104308771745083644" src="https://x.com/WeatherNation/status/2104308771745083644"></div>Winds across the northeast have reached over 60 mph in some areas.<img src="https://media.weathernationtv.com/app/uploads/2026/09/Screenshot 2026-09-27 145019-1790542232428.png">Some of the greatest concerns were along the Mid-Atlantic coastline, where repeated high-tide cycles sent water into neighborhoods and businesses and washed out roadways. Communities that frequently experience tidal flooding like Bethany Beach saw conditions worsen as the storm churned offshore.&nbsp;<div class="twitter-tweet" style="display: flex; justify-content: center" data-twitt-post-id="2103462018682703967" src="https://x.com/WeatherNation/status/2103462018682703967"></div>The impacts of this nor'easter will be winding down today but Coastal Flood Warnings and Advisories do remain in effect through the day, some through early Tuesday.<img src="https://media.weathernationtv.com/app/uploads/2026/09/through mondayyaaaaaa-1790557953543.png">The immediate coastal flooding was quickly made worse as heavy rain dumped along the Northeast coast by the weekend. <img src="https://media.weathernationtv.com/app/uploads/2026/09/WEB 1-1790601969107.png"><img src="https://media.weathernationtv.com/app/uploads/2026/09/Screenshot 2026-09-27 145215-1790542342746.png">Rounds of heavy rain and strong winds will continue off and on as the low pushes north. As the low weakens and stalls, the rain should break up and become less heavy into Monday. Lingering gusty winds, light rain, and strong surf are expected to last into early Tuesday as the low moves out of New England.<video src="https://media.weathernationtv.com/app/uploads/2026/09/overnissss-1790558041345.mp4" controls="true" width="100%"></video>Conditions should gradually improve as the storm weakens and moves away from the coast Monday, and more so Tuesday. However, dangerous surf and lingering coastal flooding could remain concerns even after the heaviest rainfall and strongest winds subside.&nbsp;Residents and travelers along the East Coast are encouraged to monitor local weather alerts, avoid flooded roadways, and use caution near beaches and other coastal areas as the storm continues to impact the region.&nbsp; Tune into WeatherNation TV for the latest.

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.

<h2>WHAT TO EXPECT</h2>Record rainfall fell this weekend across the Ohio River Valley and the Mid-Atlantic. On Monday, Ohio tacked on almost 4 more inches in spots. More rainfall is on the way, continuing the risk of flooding. Because of this risk, flood watches remain in place over the next few days across OH, PA, and WV for additional rainfall.<h2><img src="https://media.weathernationtv.com/app/uploads/2026/09/Screenshot 2026-09-22 075632-1790085405907.png">Storms &amp; Timing</h2>A frontal boundary will continue to linger, bringing more rain, with heavy rain embedded in some of the storms that develop. Rounds of rain will continue to develop through Wednesday.<video src="https://media.weathernationtv.com/app/uploads/2026/09/2026-09-22 07-58-32-1790085533334.mp4" controls="true" width="100%"></video><h2>RAINFALL TOTALS</h2>While heavy rain will be possible in some spots the next few days, at least the bulls eye is moving.
