As residents in at least five U.S. states assessed the damage on Saturday from a spree of powerful storms and tornadoes, forecasters warned of more inclement weather looming across the country.

There was a slight risk of severe storms for parts of the Southeast and Tennessee Valley on Saturday night, the National Weather Service said in an advisory at 2:39 p.m. Eastern time.

At least five states were swept by tornadoes on Friday, including Arkansas, Illinois, Kentucky, Missouri and Tennessee.

But the “main weather threats over the next couple days” were severe thunderstorms in the East and heavy snow in the West, specifically over the Sierra Nevada, the Cascade Range in the Pacific Northwest and the Northern Rockies, according to the weather service.

Damaging wind gusts were expected to hit much of the Mid-Atlantic on Saturday night, and heavy coastal rain was predicted in central California on Sunday and Monday.

“Flash flooding will be a concern for these places, and particularly for burn scar areas where debris buildup can pose a threat to life and property,” the forecast said.

Heavy rain was expected to spread into central and Southern California by Monday night, the advisory said.
