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:

• Moderate Risk of Excessive Rainfall extended further into our area for today.
• There is now a Slight Risk of Severe Weather today.

• Flash Flood Watch was extended to include all of our area, from 6AM today through 6PM Thursday.

Overview of Impacts:

• Storms become more widespread today, 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 mainly along and northwest of a line from Houma to Poplaville.

• A few storms may be locally strong to severe on Wednesday and Thursday, 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. 

• Dense fog persists this morning in some areas, especially coastal Mississippi. This should start to clear out later this morning.
