Storms topple trees, knock out power to some in NYC

NEW YORK (WABC) -- A flash flood warning was issued for parts of the region, including Brooklyn, Queens and Nassau County, as heavy rain and thunderstorms move through the area.

In New York City, Mayor Zohran Mamdani and New York City Emergency Management urged residents to be prepared as more scattered thunderstorms could still trigger localized flash flooding in some areas into Monday evening.

"We ask New Yorkers in this time to stay safe, stay prepared, and to keep an eye out for one another," said Mamdani, adding that city workers were out over the weekend clearing catch basins and preparing neighborhoods that are historically flood-prone for the impending storm.

The mayor asked New Yorkers who live in basement apartments to plan to evacuate.

"If you see water rising around you, move to higher ground," Mamdani said.

The MTA was also urging commuters to take caution and plan extra travel time.

The National Weather Service has issued a Flood Watch through 6 a.m. Tuesday.

Forecasters expect multiple rounds of heavy rain and thunderstorms capable of producing two to three inches of rainfall across much of the city, with isolated areas receiving up to six inches where storms repeatedly track over the same locations.

Rainfall rates could reach two to three inches per hour, creating the potential for rapid flash flooding, particularly in low-lying neighborhoods and areas with poor drainage.

OEM Commissioner Christina Farrell talks about how NYC if faring from the storm.

The city is also dealing with several downed trees across the region, including in Crown Heights, Brooklyn.

The extreme heat and storms over the holiday weekend created power outages. Most were restored by Con Ed, but some were still being worked on.

Sidewalks were flooded from Bay Parkway to 74th Street. Cars and buses did their best to make their way through shallow water.

LONG ISLAND

Both Nassau and Suffolk counties are under a state of emergency on Long Island.

The FourLeaf Air Show at Jones Beach had to be canceled Monday because of the weather.

Monday's weather was already packing a punch. There were more than 4,500 power outages across Nassau and Suffolk counties as of noon, and 400 trees have fallen, according to PSEG.

Gov. Kathy Hochul is on Long Island Monday and spoke about the severe weather. She says the main concern now is the flash flood warnings for Monday and Tuesday.

Residents should avoid unnecessary travel during periods of heavy rain, never drive through flooded roadways, secure outdoor items, charge electronic devices and bring pets indoors. If you encounter a downed power line, stay away from it and report outages to PSEG Long Island at 800-490-0075.

WESTCHESTER

Fallen trees brought down powerlines causing some owners to suffer two days without any power.

Workers from NYSEG along with utility crews from Central New York spent Monday morning restoring power.

The City of Rye said that parking in flood-prone areas is prohibited. The city will remove vehicles left in flood-prone areas.

The Highland Hall parking lot is closed and all other parking restrictions throughout the city are suspended.
