Emergency Managers in southeast Louisiana and south Mississippi:
A potent storm system will impact southeast Louisiana and south Mississippi over the weekend. The main time of concern for any strong to severe thunderstorms and very heavy rainfall will be Saturday night and early Sunday morning. Here is a summary of the expected impacts:
-Isolated strong to marginally severe thunderstorms with marginally severe hail of dime to quarter size, wind gusts of 40 to 60 mph, and possibly an isolated tornado or two.
-A general area of 1 to 3 inches of rainfall. Some areas could receive 2 to 3 inches of rain in a short period of time resulting in localized ponding of water in low lying and poorly drained areas.
Timing: Isolated showers and a few thunderstorms are possible Saturday afternoon, then the threat of scattered thunderstorms will rise after 7 pm Saturday evening. Later in the evening, a squall line of numerous to widespread thunderstorms is expected to move through after 10 pm through about 8 am Sunday morning, starting in western areas near Baton Rouge, the Atchafalaya River, and southwest corner of Mississippi, and moving across east and southeast coastal areas near daybreak to early morning on Sunday. Most of the heavier rainfall and stronger thunderstorms are expected along and near the squall line
