Parts of the Mid-Atlantic States — including Pennsylvania, Maryland, Delaware, Virginia and New Jersey — were on alert on Tuesday evening, as a forecast for thunderstorms and heavy rain led to flash flood warnings across the region.
The severe weather caused delays at some of the busiest airports on the East Coast, including in Baltimore, Boston, Newark, New York City and Washington.
There were more than 200 flight cancellations on Tuesday afternoon, mostly in the New York and Washington regions, according to the tracker FlightAware.
The National Weather Service said that thunderstorms could move from Northern Virginia up to New Jersey until 9 p.m. Eastern time, and warned of the possibility of damaging wind gusts up to 70 miles per hour. Flash flood warnings were issued for some areas, including Baltimore, Philadelphia and Lancaster, Pa., through the evening.
Some of the warnings on Tuesday were for areas that received significant amounts of rain the day before, resulting in what the Weather Service described as “widespread flash flooding.”
Much of Lancaster County received between two and four inches of rain on Monday night. Manheim, Pa., recorded approximately six inches, the service said.
The Weather Service warned that additional rain on Tuesday would fall on ground that was already heavily saturated.
About 60,000 utility customers in the region were without power on Tuesday evening, according to PowerOutage.us.
