<p>On Tuesday afternoon, Tropical Depression 9 formed off the Mexico coast in the southern Gulf. We expect this storm to continue to organize and strengthen as it makes its way north. By Thursday, it should reach hurricane status, making it the first one in the Atlantic this year; shattering previous satellite-era records for latest hurricane to form. As it moves north, the National Hurricane Center has its initial landfall forecast between New Orleans and Panama City Beach as a category two. Reminder, category two storms have winds between 96-110 mph. Heavy rain and flooding will be possible along the Gulf Coast states, regardless of the system's strength. For now, that is the biggest impact we're expecting.</p><p><img src="https://media.weathernationtv.com/app/uploads/2026/10/Screenshot 2026-10-06 144652-1791319622624.png"></p><p>If you're living along the Gulf Coast, now is definitely the time to really start paying attention to the forecast. There is still some uncertainty in the forecast as there is shear and dry air standing in its way as it moves north. That's why the ensemble forecasts below still don't perfectly line up. Anyone form the Louisiana coast to the Big Bend of Florida should be on alert for changes in the forecast.</p><p><img src="https://media.weathernationtv.com/app/uploads/2026/10/Screenshot 2026-10-06 145024-1791319834804.png"><img src="https://media.weathernationtv.com/app/uploads/2026/10/Screenshot 2026-10-06 043745-1791283113704.png"> <img src="https://media.weathernationtv.com/app/uploads/2026/10/Screenshot 2026-10-06 043921-1791283176257.png"></p><p>Our in-house BARON model shows nonstop heavy rain associated with a different system we've been tracking this week.

<p>Deep tropical moisture streaming north from the Gulf is combining with a slow-moving front, setting the stage for widespread showers and thunderstorms along the Gulf Coast.  Apalachicola, Florida, saw 7.49 inches of rain on Monday; this was the wettest October day on record! More heavy rainfall and flash flooding remain in place over the next couple of days.</p><h1>Timing</h1><p>After all the heavy rain throughout the Southeast over the weekend, more heavy rain will continue as a frontal boundary lingers. As this front moves south, heavy rain will shift south as well.</p><video src="https://media.weathernationtv.com/app/uploads/2026/10/JFJFJFJFSSSSS-1791336230013.mp4" controls="true" width="100%"></video><p>Some localized totals of 5-6 inches of rain will be possible.

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!
