Around 15 million people are under flood alerts from Louisiana to Georgia on Tuesday as the region braces for more heavy rains and thunderstorms that could bring up to 2 inches of rainfall to some areas.

Excessive rain is also forecast to affect an area stretching from the Carolinas to western Texas. Large hail, damaging winds and a few tornadoes could also be possible for parts of southwest Texas, including Midland and Fort Stockton.

Pictures and videos over Memorial Day weekend showed a flooded driveway in Mississippi and cars stranded in multiple inches of rain across the Dallas-Fort Worth metroplex.

A flood watch is in place Tuesday for New Orleans until 7 p.m. local time. Showers and storms will last through the evening, with up to an inch of rain expected, and some areas could see up to 2 inches.

Atlanta is also under a flood watch until 11 p.m. local time Tuesday, with up to 0.75 inches to 1.25 inches likely, and up to 2 inches possible in isolated areas.

Both New Orleans and Atlanta could get hit with hourly rainfall rates of 1 to 3 inches, so even areas not under a flood watch could face flash flooding Tuesday.

There’s more precipitation expected in the region throughout the week, with rainfall amounts to be determined.
