MILWAUKEE (Reuters) – Tornadoes and storms that already have killed at least three people and destroyed homes in the U.S. Midwest are moving east on Wednesday, the National Weather Service and media reported.

Tornado watches remained in effect from northeast Arkansas north into Ohio and eastern Pennsylvania for Wednesday morning after the band of storms rolled through the Midwest on Tuesday night, the National Weather Service said.

“Widespread damaging winds can be expected, along with some tornado risk,” the service said in an advisory.

The storm system will continue moving east toward the Atlantic Ocean, according to AccuWeather meteorologists. This is likely to bring severe thunderstorms and possible travel delays later on Wednesday to New York City, Washington, Philadelphia and Boston.

The storm has left tens of thousands of people without electricity and killed at least three people, according to local officials and media reports. One person died while driving on a Missouri freeway after strong winds swept old cars from a nearby junkyard onto the road.

Tornado spotters have already reported at least 23 twisters in Illinois, Missouri, Iowa, Tennessee and Indiana on Tuesday evening, the National Weather Service said.
