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.

Threats/Impacts:

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
