A FLASH FLOOD WATCH is posted for the entire viewing area, through Thursday morning. Additional rainfall of 1 to 3 inches with locally higher amounts will be possible. The most likely areas for heavy rainfall will be along and south of the I-10/12 corridor in Southeast Louisiana including portions of metro Baton Rouge and metro New Orleans. These heavier rainfall amounts could cause localized flash flooding issues. High rainfall rates could overwhelm drainage capacity. Ponding of water in low-lying and poorly drained areas will be possible, and flash flooding could occur where the heaviest rain occurs.

***FLASH FLOOD WATCH*** for the shaded area. We'll have updated forecasts and post warnings, if issued. #lawx #mswx pic.twitter.com/P0AqWBI5oI

Showers will be on and off for the rest of the day and everyone should expect to see a shower. It will be possible to pick up another 1-2 inches of rain. Areas that were hit hard earlier in the week will be most susceptible to flooding. Look out for high water if there is a heavy downpour in your area. Temperatures will be near 80 degrees this afternoon. Overnight we will get some dry time and temperatures in the upper 60s.
