Power remained knocked out for thousands across several eastern states on Thursday morning, according to power outage tracker PowerOutage.US.

More than 5,400 Virginians were shown still without power as well as more than 2,000 New Yorkers, 2,500 New Jerseyans, close to 4,000 North Carolinians, almost 2,500 Maryland customers and more than 5,500 residents of Pennsylvania

Outages were in the tens of thousands Wednesday evening, according to The Weather Channel.

In Penn Yan, N.Y., four people sustained minor injuries when a large structure under construction toppled due to strong winds and what some guessed was a microburst, though it could not be confirmed. 

Finger Lakes Daily News staff meteorologist Kevin Williams reported late Wednesday night that peak gusts at the time were hovering around 49 mph, according to the New York State Mesonet (NYSM).

"Certainly, if there was a microburst (not certain at this time), higher, highly localized, gusts would have been possible," Williams said in an update.

The NWS said Thursday that storms and more extreme weather are expected to hit both the East Coast from portions of Virginia to Maine and the Great Plains and central U.S., with intense winds, hail and tornado threats.
