The remnants of Hurricane Ida are expected to drop heavy rain across parts of the Mid-Atlantic and southern New England on Wednesday and Thursday, with life-threatening flash-flooding possible in much of those areas, meteorologists said.

The Mid-Atlantic and New England area should anticipate three to eight inches of rain on Wednesday and into Thursday from Ida, the National Weather Service said. The storm hit Louisiana on Sunday as a Category 4 hurricane but has since been downgraded to a tropical depression, according to the National Hurricane Center.

The governors of Virginia and West Virginia declared states of emergency on Tuesday ahead of the system’s arrival.

Widespread river flooding could occur in southern Pennsylvania and New Jersey, particularly in the Monongahela, Potomac, Susquehanna, Delaware, and lower Hudson River basins, forecasters said.

The last storm to hit the Northeast was Henri, which made landfall in southwestern Rhode Island on Aug. 22 as a tropical storm, sending lashing bands of rain across much of New England that knocked out power in most of coastal Rhode Island, forced evacuations in Connecticut, stranded dozens of motorists in New Jersey and shattered rainfall records in New York City.

At its peak, Henri left more than 140,000 households without power from New Jersey to Maine, and in New York City, cars were left stranded in flooded streets.

Meteorologists were warning on Tuesday that similar high amounts of rain could hit the region as the tropical moisture associated with Ida intersects with strong wind bands over the upper levels of the atmosphere in the Northeast, creating heavy rainfalls.

A flash flood watch will be in effect from Wednesday night to Thursday for all of Connecticut, Massachusetts and Rhode Island. Morning commutes on Thursday could be affected by drainage flooding in much of the New England and the Mid-Atlantic, particularly in metropolitan areas, meteorologists said.

In New York City and nearby areas, where a flash flood watch will also be in effect from Wednesday afternoon through Thursday afternoon, the remnants of Ida will bring a period of heavy rain and potential flash flooding, the Weather Service said.

“Ida is basically going to be exiting New England by Thursday night,” said Dan Thompson, a meteorologist with the National Weather Service. “But it’s going to drop heavy rain before it leaves.”
