WHAT: MARGINAL RISK of Excessive Rainfall today and Tuesday

SLIGHT RISK of Excessive Rainfall Wednesday

WHEN: The heavy rainfall threat may extend through the rest of this week.

WHERE: All of SE LA and S MS, with the greatest threat in areas south of the I-10/12 corridor.

CONFIDENCE: We have above average confidence in the heavy rain threat through at least mid week with typical uncertainty pertaining to who will get exactly how much rainfall.


For the heavy rainfall potential:

  • Rainfall rates in excess of 1-3 inches per hour are possible
  • High rainfall rates can quickly lead to ponding of water in low lying and poor drainage areas
  • Flash flooding will be possible in some places, especially urban areas, where high rainfall rates exceed drainage capacity
