A “powerful” storm lashed the mid-Atlantic coast Monday with heavy rain and thunderstorms, leaving 59 million people from Virginia to Maine under flood alerts, over 400,000 homes and businesses without power, and holiday travelers scrambling as airports report flight delays and cancellations.
There’s a slight risk of excessive rainfall over parts of New England through Tuesday, the National Weather Service’s Weather Prediction Center warned.
“The associated heavy rain will create mainly localized areas of flash flooding, with urban areas, roads, and small streams the most vulnerable,” the weather service said.
The same storm system battered Florida and the Carolinas with strong winds and torrential rain over the weekend — with Charleston breaking a daily record Sunday with 3.86 inches of rainfall and Gainesville, Florida, recording more than 7 inches. South Carolina also set a record for greatest storm surge from a non-tropical system with a high tide at nearly 10 feet.
The East Coast is already reeling from the impacts with more than 400,000 people across New England and New York without power as of 11 a.m., according to PowerOutage.us.
In New York City, a travel advisory is in effect due to flooding conditions on roads, power outages and high winds on bridges. The city’s emergency management office also warned of “imminent” flash flooding in Manhattan and the Bronx, warning locals to avoid basements and low-lying areas.
“Please exercise caution with your morning commute. Take mass transit and stay off the roads if possible,” Mayor Eric Adams tweeted.
Over 10,000 people in the Big Apple were without power due to the storm and there were over 200 reports of downed trees across the city, the NYC Emergency Management office said.
In Connecticut, the city of Danbury’s Emergency Management office urged locals to not drive through flooded roads with water rescues and vehicles stuck in water reported.
Amtrak said train services were temporarily disrupted between Providence, Rhode Island, and Boston due to winter storm conditions causing “overhead power issues.”
There’s more than 500 delays nationwide and more than 370 cancellations, a number likely to keep growing Monday ahead of holiday travel chaos that sees millions take to the skies a week ahead of Christmas, according to FlightAware data. It comes after a weekend that saw a dizzying number of delays — more than 10,000 — and almost 200 cancellations.
Thirty-eight million people in the Northeast are also under wind alerts. In the past 48 hours, New York’s LaGuardia Airport clocked a 54 mph wind gust; Brookhaven Calabro Airport in Shirley, New York, a 60 mph wind gust; and Boston Logan International Airport, a 51 mph gust.
A ground stop was issued at Boston Logan International Airport due to wind through noon ET.
By the end of today, every single state on the East Coast will have experienced at least two inches of rain.
The threat of heavy rain will end Tuesday as the system moves further into Canada by Monday evening.
Lake-effect snow downwind of the Great Lakes and upslope snow over parts of the northern and the central Appalachians are also in the forecast Monday through Wednesday, the weather service said.
The heaviest snow Monday will fall over parts of the central Appalachians, southwest of Lake Michigan in Michigan and Indiana, and along the central and the eastern shores of Lake Erie in Ohio and New York. The lake-effect snow will lighten up Tuesday and end over the upper Great Lakes, forecasters said.
Meanwhile, a storm is moving onshore over the West Coast on Monday that will also produce significant rainfall as well as snow in the Sierra Nevada Mountains over the next few days.
