Parts of the South and Midwest, still reeling from violent storms, tornadoes and flooding that have killed at least eight people this week, faced an ongoing threat of catastrophic flooding Friday that forecasters said would stretch into the weekend.

Florida's Panhandle and portions of North Florida could see some severe thunderstorms Sunday, April 6. From the Gulf Coast and the Interstate 10 corridor on northward to western North Carolina and South Carolina, thunderstorms could bring isolated tornadoes, heavy downpours and hail, according to AccuWeather.

The National Weather Service warned on Thursday of "generational" floods in the U.S. South and Midwest as storms ripped across a swath of the country from Texas to Michigan, whipping up tornadoes and killing two people.
