Changes from previous update:
WHAT: MARGINAL RISK of Excessive Rainfall Today
SLIGHT RISK of Excessive Rainfall Wednesday through Saturday
WHEN: Most days will have the highest rainfall potential during the daylight hours each day through Saturday.
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. Increasing concern for flash flooding starting Wednesday along as well as south and east of a line from Pierre Part LA to Poplarville MS.
For the heavy rainfall potential:
Rainfall rates in excess of 2-4 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
