The deadly storm was packing maximum sustained winds of 50 miles per hour.The National Weather Service said it doesn’t anticipate a significant change in Elsa’s strength through Friday and that the storm, which has weakened from the first hurricane of the 2021 Atlantic season, is forecast to become a post-tropical cyclone by nighttime. Elsa is expected to move offshore from the northeastern U.S. coast by late Friday afternoon before heading to Canada’s Atlantic provinces by late Friday night and Saturday.Flash flood watches are still in effect for the mid-Atlantic and northeastern regions, from Virginia to Maine. That includes several major cities, such as Philadelphia, New York City and Boston. The storm’s current track shows it hugging the northeast coastline, with those areas expected to see the heaviest rainfall.Much of the northeast is forecast to receive 2 to 4 inches of rainfall through Friday, with up to 6 inches possible in parts of New York, Connecticut and Massachusetts. That could trigger “considerable flash and urban flooding,” the National Weather Service warned.Tropical storm warnings also remain in effect for a large swath of the East Coast, from North Carolina’s Outer Banks to Massachusetts.Meanwhile, a “tornado or two” will be possible over parts of New York’s Long Island and southeastern New England through early Friday afternoon, according to the National Weather Service.Severe weather has already disrupted flight schedules at LaGuardia Airport and John F. Kennedy International Airport in New York City’s Queens borough. New York City has also closed its mobile COVID-19 vaccination clinics through Friday due to the forecast.New York City’s Metropolitan Transportation Authority said there were system-wide delays for buses due to Elsa and the storm could impact service along some subway and rail lines. Meanwhile, empty tractor-trailers and tandem trucks are banned on the seven bridges and two tunnels that the MTA manages until at least noon on Friday due to the weather.Copyright © 2021, ABC Audio.
