WASHINGTON:Nearly 90 million people in the US as the country celebrates the Fourth of July holiday on Tuesday, with potential damaging wind gusts, power outages, large hail and possible tornadoes.

Scattered strong to severe thunderstorms and thunderstorm clusters may develop across the Mid-Atlantic Region and portions of the northern Great Plains, according to the US National Weather Service.

Severe storm chances are increasing in these regions, Xinhua news agency quoted the weather service as saying.

Severe weather has already battered parts of the US over the weekend, hitting states including Missouri, Ohio, Kentucky, Illinois and Iowa.
