Howdy!
Post Tropical Cyclone Arthur has moved overland over Louisiana into Mississippi and is producing heavy rainfall, tornado warnings, strong winds, and severe weather. As we can see in the NWS radar, much is happening currently in the southeast United States.
The rain that we are seeing will continue today into the weekend. Flash flooding is very possible for a lot of people, so do take these warnings seriously and see how they will impact you relative to your location.
For today, the Weather Prediction Center has marked the Mississippi and Alabama gulf coasts under high risk of excessive rainfall, moderate for some of southeast Louisiana, southern Mississippi, much of Alabama, and parts of western Georgia. The QPF also points to the southern portions of the region getting heavy rainfall, several inches of rain can fall in a short period of time.
Tomorrow will still be important to look at as that deep tropical moisture will still be present, fueling rain and thunderstorms. The WPC has the area under moderate, slight, and marginal for excessive rainfall. Main areas of concern are southern Alabama and a little of Mississippi that are under moderate risk. Slight risk for a lot of the region, so do still take this seriously!
