By Rich McKay and Tatiana Bautzer (Reuters) -Portions of Pennsylvania, New York and Mid-Atlantic and Southeast states were still under a National Weather Service watch for damaging wind and tornadoes,

The death toll from tornadoes and violent storms that ravaged the central and southern United States over the weekend has risen to at least 40 people, with dozens more injured, local authorities said.

According to the SPC: “The HIGH risk area almost always means a major severe weather outbreak is expected, with great coverage of severe weather and enhanced likelihood of extreme severe (i.e., violent tornadoes or extreme convective wind events over a large area).”

A video recorded in Calera, Alabama, shows significant damage left behind after powerful storms swept through the region over the weekend. The powerful storm system responsible for the damage has left more than 30 people dead from tornadoes and a dust storm.

The weakening but still volatile weather system was moving Monday into the U.S. Southeast and Mid-Atlantic, bringing thunderstorms, hail, damaging winds and the potential for more tornadoes.

Violent tornadoes and high winds decimated homes, wiped out schools and toppled semitractor-trailers as a monster storm that killed at least 32 people ripped its way across the central and southern U.

A powerful storm system that tore across the United States in recent days is winding down Monday, but in its wake are devastated communities across states hit with violent tornadoes, wildfires and dust storms spun off by the massive system.
