Repeated storms could unleash dangerous flash flooding in the South through next week

Millions of Americans will experience repeated and intense downpours. As a result, a Level 2 out of 4 flash flood threat is in effect on Monday, with the highest risk extending from Oklahoma through the Ozarks.

As the official start of summer is almost upon us, millions of Americans look to enjoy the great outdoors and hit the beach, but unfortunately, people in the South may not be so lucky.

Forecasters are expecting heavy downpours across regions of the southern U.S. starting Sunday and into the start of next week, as lingering tropical moisture and a stationary front combine to allow showers and storms.

This renewed threat comes as a stalling cold front will trigger widespread heavy rain across Oklahoma, Arkansas, Tennessee and northern Mississippi.

"A widespread 1 to 2 inches of rain looks likely, though localized pockets of heavier downpours could exceed those totals in Oklahoma and Arkansas," the FOX Forecast Center said.
