Heavy rain and thunderstorms pelted much of Long Island late Monday before being replaced by showers and patchy fog, both forecast to continue overnight.
Meanwhile, the ground stops at Kennedy and LaGuardia airports, issued by the Federal Aviation Administration earlier Monday evening, were lifted before 8 p.m.
The National Weather Service in Upton on Monday evening issued a flash flood warning until 9:30 p.m. for western Nassau County, along with Queens, Brooklyn and the Bronx.
Minor flooding was expected in low-lying and poor drainage areas with rainfall amounts totaling 1 to 1.5 inches, the weather service said. There were no reports of flooding-related problems late Monday.
The heaviest rain, however, was forecast in Queens, New Jersey, the Lower Hudson Valley and southern Connecticut.
Late Monday, the MTA was reporting flood-related delays on several subway lines, and warning Metro-North riders to expect similar delays on the Harlem and New Haven lines in and out of Grand Central Station.
In addition, the NYPD reported that due to flooding conditions, the Cross Bronx Expressway at Jerome Avenue had been blocked in both directions.
While rain also is in the forecast for much of Long Island Tuesday, Wednesday and perhaps even Thursday, the weather service said those in western Nassau will likely see no more than an eighth to a quarter-inch of rain Monday, while those on the East End will see only trace amounts of rain, if any.
