The National Weather Service office in Slidell issued the flash flood watch to run from 4 a.m. Friday into 7 a.m. Saturday for the Baton Rouge area. In southwest Louisiana, including Lafayette, the rain has already started prompting a flash flood watch to start immediately and run until 7 a.m. Saturday morning.

A flash flood watch means conditions are right for flooding to occur while a warning means the flooding is occurring or will happen soon.

Rainfall totals for the next couple days could be 2-4 inches of rain, but there is potential for some areas to see much higher amounts in excess of 6 inches.

Although the initial flash flood watch is for the area west of I-55, it’s likely the watches will be expanded eastward at some point, according to the National Weather Service.

The front moving through the area should settle over the northern Gulf of Mexico sometime Monday which will help direct a potential weather system in the southern Gulf to the northeast. The National Hurricane Center is currently monitoring this potential weather system in the southern Gulf of Mexico and as of Thursday afternoon gave it a 40 percent chance of developing into a tropical system in the next five days.
