A slight risk of flash flooding hangs over southeast Louisiana and south Mississippi through Thursday morning.
"The threat for very heavy rainfall will remain across much of south Mississippi and southeast Louisiana through the end of the workweek, as a very moist airmass remains across the area," said the local National Weather Service office Wednesday. "Showers and thunderstorms, mainly during the daytime hours, will produce a few spots of very heavy rainfall. With rain falling at the rate of 2 to 3 inches in an hour or more, even 30 to 45 minutes of very heavy rain in one location has the potential to briefly overwhelm drainage system."
The NWS said the greatest threat of flash flooding is today, but will extend into Thursday.
"People travelling over the next few days should be prepared for the potential of brief flooding of streets and low lying areas," the NWS added.
In the tropical Atlantic, there remains a low chance of development for a tropical wave west-southwest of the Cabo Verde Islands.
"Some gradual development of this system is still possible over the next few days. However, environmental conditions are forecast to become less favorable by this weekend," said the National Hurricane Center.
