Here is an update concerning the heavy rain threat on Friday and Saturday:
WHAT: Slight risk of Heavy Rain that could lead to flash flooding today and a Marginal Risk on Saturday. Also, a Flood Watch remains in effect for portions of southern Louisiana until 1 a.m. on Saturday
WHEN: Mainly during the morning and early afternoon today, and the afternoon and evening tomorrow
WHERE: Across SE LA and coastal MS, but especially along the SE LA coast
CONFIDENCE: We are confident there will be thunderstorms across the area. We have less confidence that any of them will result in flash flooding or where the heaviest rain will be.
Impacts:
- Rainfall of 0.5 to 2 inches is currently forecast. Local amounts of 3-4 inches or more are likely.
- Localized flash flooding will continue to be a threat as some storms will be capable of producing high rainfall rates in excess of 2″ per hour.
- Ponding of water in low lying and poor drainage areas is likely, with some road closures still possible. Urban areas will be particularly vulnerable as high rainfall rates can easily overwhelm local drainage capacity.
