Major rain headed for Panama City and Bay County into the weekend. Here's what we know.

Panama City can see some very heavy rainfall later this week.

The Florida Department of Emergency Management said 6 to 10 inches of rain are possible across the coastal Panhandle and west Big Bend area into the weekend. Some areas could see more than 12 inches.

A system that brought storms that drenched Texas over Labor Day weekend is expected to bring that same rain to the Florida Panhandle. While it disappeared off the NHC map after the weekend, storms associated with it continued to drift east. Now, forecasters are warning Gulf Coast residents to be prepared for heavy rain associated with the system.

"Impacts are expected from Southern Alabama, Florida's Panhandle and stretching to Jacksonville and into Georgia, with 4-8" of rain is expected between Friday and Saturday," said AccuWeather Lead Hurricane Forecaster Alex DaSilva. "The rain won't be limited to North Florida. Most of the peninsula can expect rainfall, which decreases the farther south you go. Tampa and Daytona Beach could see 2-4", with Saturday being the heaviest. Farther south in Florida, expect rainfall amounts ranging from 1 to 3 inches."

While the trough of low pressure has a low chance of becoming a named tropical storm, that doesn't mean it won't bring dangerous conditions to Gulf Coast states from Texas to Florida and as far north as North Carolina. Of special concern to AccuWeather forecasters is southern Louisiana, which could see 6 to 12 inches of rain. Some areas could see up to 18 inches, said AccuWeather Lead Hurricane Forecaster Alex DaSilva.

"The system should move into into the Atlantic. There's the possibility of development in the Atlantic, although water temperatures aren't as warm as they are in the Gulf, but are still in the mid 80s," said DaSilva. "That's warm enough to support tropical development but there is more wind shear there so the environment is not extremely favorable for development. Even if there is development, there's no threat to the U.S. It would be pushed out to sea."

Upper-level winds are expected to become less conducive for development by Friday and Saturday as a frontal boundary approaches the system.

Although development is unlikely, heavy rainfall is expected across portions of the northern Gulf Coast during the next day or so.

• Formation chance through 48 hours: low, 10 percent.
• Formation chance through 7 days: low, 10 percent.

Is there a hurricane coming to Florida?

No. The system of low pressure in the Gulf of Mexico currently has a low chance of development , according to the latest advisory from the National Hurricane Center.

"We've never seen the Gulf as warm as it is right now. Temperatures are mostly in the mid to upper 80s when averaged out. Tropical systems need 80 degrees to develop," DaSilva said.

"There's a low chance it can get its act together. Because of the warm water, it can try to spin up and it's not out of the realm of possibility it could get a name."

The next name of the 2024 Atlantic hurricane season is Francine.

Radar shows 'big blowup of thunderstorms' in Gulf of Mexico

"Looking at the radar (shortly before 10 a.m. Thursday), there's been a big blowup of thunderstorms in the northwestern Gulf. It may be trying to get better organized, but there's a low chance of it getting a name. But that also means there could be more rainfall for Louisiana," DaSilva said.

"Its a very slow mover, which is contributing to heavy rain. If it gets its act together and tries to consolidate, there could be even more rain. We'll have to watch it very closely over the next couple of days."
