New Yorkers can expect to see bursts of heavy rainfall throughout Tuesday, with isolated showers and thunderstorms that could lead to flash flooding in some areas, according to a travel advisory from the city’s emergency management agency.
The city issued a travel advisory for Monday afternoon through Tuesday and mobilized crews to inspect and clean drains in areas vulnerable to flooding.
The potential for scattered flash floods will last until Tuesday around 5 p.m., according to the National Weather Service, with between two and four inches of rainfall expected, while some areas across the region may get more. Any flash floods will likely be localized and mainly pose a concern for urban areas, roads and small streams.
The Metropolitan Transportation Authority said on Monday that weather response teams would be stationed at key locations in the city’s subways as a precaution against flooding, among other measures.
The heaviest rainfall was expected on Monday night through midday Tuesday, according to the National Weather Service. As of 9:20 a.m. on Tuesday, Danbury, Conn., had recorded 4.22 inches of rainfall, among the most in the area. The entire New York City region recorded less than one inch of total rainfall in August, according to data collected by the Weather Service.
People who live in basement apartments should prepare to move to higher ground during periods of heavy rain, the advisory from the city said. And pedestrians should avoid walking through flooded areas and use caution when traveling, such as by avoiding flooded subway stations, the emergency management agency advised.
