The chance of rain is 90 percent during the day Tuesday and 100 percent Tuesday night, forecasters said.

Winds will be from the east Tuesday at about 15 mph and the temperature should hit a high of 54 degrees, forecasters said.

“Wet weather all day,” News 12 Long Island meteorologist Rich Hoffman said. “Wet roadways this morning and all day long, through the morning rush hour and the evening rush hour. It’s going to be a slow go.”

The weather was causing delays at LaGuardia and Kennedy airports, and the Port Authority, which operates the airports, was advising travelers to call their airlines for information about specific flights.
