Remnants of Isaias to soak New York City Sunday, with 1 to 2 inches of rain possible

Enjoy Saturday. The remnants of Hurricane Isaias are expected to bring a soaking rain to New York City on Sunday, with the heaviest downpours arriving in the afternoon and evening of the holiday weekend.

The forecast

The National Weather Service's forecast for the city calls for a partly sunny Saturday with a high near 68 and a mostly cloudy night with a low around 60. Rain is expected after 8 a.m. Sunday, with a 90% chance of rain and a high near 67. East winds of 9 to 16 mph could gust as high as 26 mph. The weather service expects a half to three-quarters of an inch of rain during the day.

The bigger totals come Sunday night. The NWS forecast calls for rain, a chance of thunderstorms and another 1 to 2 inches of rain, with northeast winds gusting to 29 mph. Monday, Columbus Day, brings a chance of rain and a slight chance of thunderstorms before 2 p.m., then partly sunny skies and a high near 70.

ABC7's AccuWeather meteorologists say the storm is what is left of Isaias, which made landfall on the Gulf Coast this week as a Category 2 hurricane. They expect 1 to 2 inches of rain across much of the region, with localized totals of 2 to 3 inches where heavier downpours persist, and say the storm's leftover circulation could pass directly over the area, raising rainfall rates and bringing occasional thunder. The station has issued an AccuWeather Alert for the second half of Sunday through Sunday night and reports that the federal Weather Prediction Center put parts of the region under a marginal risk of flash flooding.
