The Gulf Coast will be inundated with heavy tropical rains through Tuesday, leaving millions of Americans at risk of flooding in the wake of the deadly deluges in Texas earlier this month.

The potential tropical storm — officially dubbed Invest 93L by the National Hurricane Center — has drenched parts of Florida and Louisiana for several days and is now moving westward, according to Fox Weather.

Millions across the Gulf states are now bracing for the storm, which experts believe has a small window to develop into an all out tropical storm prior to passing over the Mississippi Valley, the Weather Channel reported.

Flooding from heavy rainfall is expected throughout the storm’s path — particularly in Louisiana where flood advisories have been issued through Saturday in several cities including Baton Rouge and Lafayette.

Computer forecast models show rainfall picking up Friday and lasting through the weekend across the region — with at least 1-3 inches of rainfall from the Houston, Texas, area to Panama City, Florida, and as many as 8 inches of rain in the area around Lafayette, Louisiana, Fox Weather stated.

Parts of both Alabama and Mississippi are also expected to experience episodes of flooding downpours, according to Accuweather.

The storm is expected to expand northward and wind down as it reaches the Arkansas border towards the end of the week, that weather authority reported.

Just six inches of moving water is considered enough to knock an adult off their feet and cars will stall out and float in just one foot of water, according to experts.

The Sunshine State has already suffered serious flooding problems from the influx of tropical moisture associated with Invest 93L.

On Saturday, Plant City experienced nearly one-foot of rainfall within just a few hours on Monday, flooding streets and homes, Fox Weather reported.

No injuries were associated with that flood — but across the state in St. Augustine three people were struck by lightning with one person suffering critical injuries, the outlet reported.

Earlier this week, volunteers combing through the wreckage of the deadly July 4 flooding in Kerr County, Texas, were evacuated due to the possibility of yet another flood.

The death toll of that flooding reached 129 people, including dozens of children who were staying at camps along the Guadalupe River — which surged 20 feet in just 90 minutes in the early hours of July 4.
