Persistent areas of rain and thunderstorms will set up over the southern states through early this week, raising concerns for urban and flash flooding.
Torrential rainfall caused flooding in the Montgomery, Alabama, area late Saturday resulting in numerous flooded roadways. A total of 8.15 inches of rain fell in Montgomery on Saturday, making it the wettest May day on record in the city.
Additionally, 10.02 inches of rain were measured near Frio Town, Texas, southwest of San Antonio, in the 24 hours ending 7 a.m. CDT Sunday morning.
Sunday afternoon, water and debris flooded some roadways in Zapata and San Ygnacio, Texas.

Current Radar, Watches and Warnings
For this reason, the National Weather Service has hoisted flash flood watches for parts of southeast Texas, southern Louisiana, southern Mississippi, southern Alabama, the western Florida Panhandle and the southern Appalachians.
Here's a general outlook of what to expect in the days ahead.
- Monday: Heavy rain and thunderstorms are expected along the Gulf Coast from south-central and southeast Texas to southern Alabama. Flash flooding will likely occur where thunderstorm clusters stall or move too slowly, and the best chance of this happening is in southeast Louisiana and far southern Mississippi.
- Tuesday: The area of heavy rain and thunderstorms will slide a bit east, as southeast Louisiana through Virginia runs the highest risk for urban and flash flooding. This is the day flooding may be the most widespread, with the most moisture available to feed storms over a larger area.
- Wednesday: Lingering showers and thunderstorms are possible near the Southeast coast from North Carolina to central Florida. Locally heavy downpours remain possible, which could lead to additional areas of flooding. This rainfall, however, will be beneficial for parts of the Florida Peninsula experiencing drought conditions.
The best chance of greater than 3 inches of rain will occur in a swath from south-central Texas eastward through the Gulf Coast region to the Carolinas. A few places may even see more than 5 inches of rainfall, including southeast Louisiana.

The good news is that flood-ravaged Oklahoma, Arkansas and Missouri will avoid the majority of the heavy rainfall.
In addition, this rainfall will likely be beneficial in easing drought conditions that remain in place across much of Georgia, Florida and Alabama, as well as northeastern Mississippi and western South Carolina.
