Here is an update from the National Weather Service in New Orleans concerning the risk for flash flooding across portions of the area mid to late-week.
Changes since Previous Update:
No major changes pertaining to the heavy rain/flooding risk and thoughts this week going into early this weekend.
Will be issuing with a marine dense fog advisory for coastal areas this evening into Wednesday morning.
Will be issuing a Coastal Flood Advisory for east-facing shorelines/coastal MS for high-tide cycle tonight.
Overview of Impacts:
Scattered to isolated showers / few storms this evening/tonight.
The main concern for our area will begin early Wednesday thru Friday, as storms become more widespread by entering from the west and may slow down/train over the same areas leading to the risk of flash flooding.
Main concern and highest confidence for flash flooding will be generally from near Baton Rouge, LA to McComb, MS on north, but flash flooding will be possible across the entire area.
A few storms may be locally strong to severe on Wednesday, with damaging winds and isolated tornadoes possible.
Multiple waves of heavy t-storms will persist at times into Friday, before the last round pushes through on Saturday, exiting to the east thereafter.
Rises on area rivers/streams can be expected. Smaller tributaries could reach minor to moderate flood stages.
