In Pennsylvania, where the storm dumped heavy snow for hours, two people were killed and several others injured after a crash involving 30 to 60 vehicles on Interstate 80 in Clinton County, authorities said.
In Central Park in New York City, there were more than six inches of snow and sleet early Thursday morning, the service said.
Heavy snowfall caused 27 vehicles to pile up on Wednesday, what officials are calling a chain reaction event, on the Henry Hudson Bridge, Lt. Thomas Antonetti of the New York Police Department told CNN. There were no serious injuries, Antonetti added.
Six people were rushed to area hospitals for their injuries, according to CNN affiliate WABC.
Transportation systems in New York, New Jersey and Connecticut were all affected by the storm, officials said. NJ Transit announced that some bus and train services would remain suspended Thursday morning. The New York City Ferry also announced a delayed departure Thursday, saying it would not operate during the morning rush hours “while crews are working to keep passengers safe on landings.”
New York City Mayor Bill de Blasio announced that all school buildings would be closed on Thursday and in-person learning was canceled.
It wasn’t just snow
But the storm didn’t just dump snow. Powerful gusts of wind – of around 55 to 65 mph – from Delaware to New Jersey caused minor damage, Guy said. The coastline will likely continue to experience high winds from New Jersey to Massachusetts all day Thursday, with a possibility of coastal flooding from Delaware through New Jersey, Guy said.
“The heavy snow will continue as the storm heads northeast and the heavy snowfall will completely leave the area by late afternoon – early evening,” he added.
The southern part of the system also pushed a cold front through central Florida on Wednesday, spawning several tornadoes in Pinellas and Hillsborough counties, Guy said.
In neighboring Polk County, Sheriff Grady Judd said authorities were dispatched Wednesday evening after reports of a possible tornado just north of the city limits of Lakeland.
MPs arrived in the area and saw “extensive damage on two streets,” Judd said, adding that two houses appeared to be “uninhabitable at this point”.
“There is significant damage to trees and other homes in the area,” the sheriff said. “We started going door to door… to check security and make sure there were no injuries. ”
The sheriff said they had not received any reports of injuries “even though there had been significant damage”.
