The National Weather Service in Slidell, LA has issued a Flash Flood Watch in effect for all of southeast Louisiana and south Mississippi through noon Monday. A rainy pattern will develop late on Sunday and last through the overnight hours into Monday morning.
Overall, we should see rain totals in the 2 to 4 inch range, however there could be some localized areas of higher amounts. Be sure your storm drains are cleared of debris to allow for proper drainage.
There’s high confidence in computer guidance that a “training effect” may set up across a portion of southeast Louisiana, however where this line sets up is hard to say. We’ll just have to monitor radar trends toward the early morning hours. Regardless, this could cause problems in the Baton Rouge to New Orleans areas, as well as other surrounding cities such as Houma, Hammond and Slidell.
