NEW YORK, May 19 (Xinhua) -- A severe storm system was expected to bring strong winds and large hail, possibly the size of baseballs, to parts of the Midwest of the United States through Monday night, a day after tornadoes downed power lines and trees and damaged buildings across the Great Plains.

Forecasters warned of potential for "all severe hazards," including tornadoes, especially in the central and southern Plains. The National Weather Service in Wichita, Kansas, warned that severe thunderstorms were likely on Monday afternoon and evening, primarily along and east of Interstate 135.

Midwest Energy Inc., an energy provider in Kansas, was quoted by The New York Times as saying early Monday that crews were working to restore power after a tornado caused damaged in the city of Plevna.

On Sunday, more than 20 tornadoes were reported across Colorado, Kansas, Texas, Oklahoma and Nebraska, according to the National Weather Service. The outbreak of severe weather comes just days after tornadoes killed at least 25 people in Missouri and Kentucky alone.
