A flood watch will go into effect for much of south Louisiana later this week as a slow-moving low-pressure system heads toward the Gulf of Mexico, bringing with it the potential for downpours and flash flooding along the Gulf Coast.

So far in 2025, National Weather Service offices have issued more flood warnings than any other year on record dating back to 1986.

There’s growing concern a potential tropical system could bring significant flooding to the Gulf Coast, but questions remain in the forecast.

A tropical storm may form this week, bringing risks of flash flooding and strong thunderstorms from Florida to Louisiana.

Regardless of development, heavy rainfall is expected over portions of Florida, which could bring localized flash flooding through mid-week.

Here's a parish-by-parish breakdown of possible rain totals expected. This can, and likely will, change over the next 24 hours as we continue to monitor this system.

A disturbance called Invest 93L by the National Hurricane Center could turn into a tropical depression or the next named storm of hurricane season.

The Gulf Coast is bracing for a potential tropical storm as Invest 93L shows increasing signs of developing into Dexter, with landfall possible as early as this week, the FOX Forecast Center warns.
