The National Weather Service says millions of people in the Midwest and Northeast face the threat of extremely hazardous weather over the next 24 to 48 hours.
This weather pattern follows violent storms and tornadoes that swept through Texas, Oklahoma and Arkansas Saturday night, killing at least 18 people. As of press time, more than 400,000 homes and businesses were without power in the region.
Storms are expected to produce strong winds and 'large to large hail' before the threat grows to strong winds themselves as the night progresses.
Flash flooding will also occur in numerous areas.
“Severe storms are expected to continue across the eastern Ozark Plateau into the Ohio and Tennessee Valleys this evening and overnight. The NWS said in a weather advisory late Sunday that tornadoes, with strong to strong winds and large and very large hail, will remain a major concern this evening, transitioning into a widespread wind threat overnight. “The associated heavy rainfall will cause flash flooding in numerous areas.”
“All significant hazards must occur, including tornadoes, very large hail, and severe, damaging winds. [at some point]“The Storm Prediction Center said. “Some of the tornadoes could be strong.”
Bad weather caused about 20,000 flight delays and nearly 1,000 flight cancellations involving flights within, into and out of the U.S., according to FlightAware.com, a service that monitors such information.
