Here is an update concerning the heavy rain threat Thursday through this weekend:
WHAT: MARGINAL RISK of Heavy Rain that could lead to flash flooding
WHEN: Thursday through Sunday, mainly in the late morning to early evening each day.
WHERE: All of southeast Louisiana and southern/coastal Mississippi
CONFIDENCE: We are confident that there will be thunderstorms across the area over the next few days and that a few will likely produce heavy rainfall. We are less confident in exactly where the greatest threat will be.
IMPACTS:
- Rainfall of 1 to 3 inches is currently forecast tomorrow through Sunday. Areas that receive multiple rounds and training of storms could see locally 3-5 inches of rainfall through Sunday.
- High rainfall rates will quickly lead to runoff with ponding of water in low lying areas and localized flash flooding.
