Louisiana could get up to 20 inches of rain from potential tropical storm this weekend
It's going to be a wet weekend.
Parts of Louisiana can expect up to 20 inches of rain over the weekend due to a potential tropical depression brewing in the Gulf of Mexico, AccuWeather senior meteorologist Rob Miller said.
The storm is forecast to bring the heaviest rainfall to southern and eastern Louisiana and other parts of the Gulf Coast including southern Mississippi, southwestern Alabama and the western Florida Panhandle, Miller said. Eight to 12 inches of rain over a day or two are likely, as well as 20 inches in three days.
Two to 8 inches of rain could reach as far north as southern Tennessee, as far west as the Texas-Louisiana border and as far east as the eastern Florida Panhandle, meteorologists said.
Furthermore, the storm, regardless of strength, could dump 1-2 inches of rain an hour over several hours along the Gulf Coast, Miller said.

The Gulf storm, which has a 90% chance of developing into a tropical or subtropical depression as early as Thursday night, is forecast to make landfall along the Louisiana coastline, according to AccuWeather meteorologists. Landfall, however, can occur anywhere from the Texas-Louisiana border to the Florida Panhandle.
Should the storm develop further, it would be Tropical Storm Claudette, the third named store of the 2021 Atlantic hurricane season.
Invest 92L is currently bringing disorganized cloudiness, showers and thunderstorms to the southwestern Gulf of Mexico. The storm is expected to start moving northward Thursday, according to the latest National Hurricane Center forecast.
The disorganization of the storm — or what meteorologist Tim Destri calls "messy" and "lopsided" — is what determines where the heaviest rain will fall.
The heaviest rainfall is expected to be "pretty lopsided on the east side, and in some cases, even as much as over 100 miles or 150 miles or more east of the center," the National Weather Service - Baton Rouge/New Orleans meteorologist told the USA TODAY Network on Tuesday.
Miller's forecast predicts the same widespread impact.
"Since southwesterly wind shear is already affecting the feature ... much of and perhaps all of the downpours will occur on the eastern side of the storm center and may extend across hundreds of miles," he said.
