Incredible video was captured in Plano, Texas, of ice sheets flying off the roof of an apartment complex and onto parked cars.
"Holy freakin' moly!" one woman shouted as she watched the avalanche of ice slide off her building.
Several cars were damaged, but miraculously, no injuries were reported.
With temperatures rising in Texas, residents have been warned to be extra vigilant around tall buildings where melting ice could fall to the ground.
After walloping Texas, the wintry weather moved on to the East Coast on Sunday, where it caused highway pileups and resulted in thousands of flights being canceled or delayed.
