More than 40 million Americans are under alert for the winter storm. Heavy snow and blizzards hit the northwestern part of the country Monday, while cities such as Philadelphia, New York and Boston are expecting record snowfall accumulations.
At least six states have declared a state of emergency in recent hours:
- Connecticut: "I have signed an emergency order prohibiting all commercial vehicles from traveling on all limited access highways statewide in Connecticut," Governor Ned Lamont tweeted. "This order takes effect at 5PM today and will remain in effect until further notice."
- Massachusetts: "The storm poses an imminent threat to public safety with potential flooding, downed trees, power outages, storm surges, blizzard conditions along the coast, and property damage," read the state emergency declaration. The measure went into effect Sunday.
- New Jersey: State Police imposed a travel ban until at least noon Monday. Governor Mikie Sherrill described in her emergency declaration, "blizzard conditions with wind gusts up to 55 miles per hour, and heavy and widespread snow accumulations exceeding 12 inches, with locally higher amounts as high as 18 to 24 inches possible."
- New York: Governor Kathy Hochul declared a state of emergency for about 20 counties and deployed the National Guard. "Please continue to limit any non-essential travel and abide by local travel restrictions so our plow drivers can do their jobs," Hochul tweeted in the final hours and recommended visiting http://511ny.org for more information.
- Rhode Island: "We’re asking Rhode Islanders to take this storm seriously and stay home," Gov. Dan McKee asked as he signed the state of emergency on Sunday. "This is an all-hands-on-deck response. Our state agencies have the resources and manpower they need to respond and keep Rhode Islanders safe."
- Delaware: "I want to express my sincere gratitude to the frontline workers who worked through the night to keep Delawareans safe," stated Governor Matt Meyer on Monday, after issuing an emergency declaration on Sunday. "Delaware is stronger because of you."
