Thunderstorms were expected to bring as much as 1.5 inches of rain to the New York area on Thursday, a week after the region was battered by the remnants of Hurricane Ida.
The National Weather Service said there was a “slight risk” of flash flooding and severe thunderstorms, mainly in northeast New Jersey and the Lower Hudson Valley. The Weather Service also warned of the potential for damaging winds and hail and said that an “isolated tornado cannot be ruled out.”
The storms came as many communities were still recovering from the damage caused by Ida, which killed at least 46 people across four states.
Overall, the storms were expected to bring 0.5 to 1.5 inches of rain to the New York region, although 2 to 2.25 inches were possible in a worst-case scenario, the Weather Service said. It noted that flooding was possible in urban areas and in communities where small rivers, streams and creeks were already swollen.
New York City was expecting 0.75 inches to 1 inch of rain, with some areas possibly receiving 1.25 inches.
“These systems are not forecast to be severe at this time, but please be prepared as conditions may change,” the New York City Emergency Management Department said.
Mayor Bill de Blasio of New York said at a news conference on Wednesday morning that the heaviest downpours were possible after midnight, bringing about half an inch of rain.
At a news conference on Wednesday morning, Mayor Bill de Blasio of New York said, “Obviously, we’re concerned about folks who were hit that any new water could be a problem. And we’re also concerned that we could see more than is projected.”
Mr. de Blasio urged residents and business owners to take precautions and said that city workers would be “out in force,” cleaning catch basins, particularly in areas hard hit by Ida.
Gov. Philip D. Murphy of New Jersey also asked residents to be aware of possible flooding.
“Please take every precaution given that the ground in many places remains saturated,” Mr. Murphy said on Twitter. “The potential for flash flooding always exists with a quick-moving thunderstorm. Do not attempt to drive into standing water.”
