Long Island weather: Coastal flood advisories for South Shore through Monday evening

As the leftover rain and winds of Hurricane Ian move out, Long Islanders can expect still more spotty rain and gusty conditions early in the week before sunshine returns, according to the National Weather Service.

There is an ongoing coastal flood advisory for southwest Suffolk until Monday at 8 p.m. and a similar advisory for southern Nassau from midnight Sunday until 7 p.m. Monday, the weather service said.

"Minor to locally moderate flooding is expected in the more vulnerable locations near the waterfront and shoreline, including roads, parking lots, parks, lawns, and homes and businesses with basements near the waterfront. Road closures are likely, and vehicles parked in vulnerable areas near the waterfront will likely become flooded," the weather service said in a Sunday evening alert.

“What we saw over the weekend were indirect impacts from the remnants of [Hurricane] Ian, but now what’s happening is that low pressure has dissipated and it’s going to restrengthen into another coastal low early in the week,” said James Tomasini, a National Weather Service meteorologist.

After a rainy weekend, Monday will dry out with a forecast of partly sunny skies and a high in the low 60s. Northeast winds will be between 18 to 21 mph.

Monday night will be mostly cloudy with a low near 46 and northeast winds staying around at between 14 to 17 mph. The forecast includes a 30% chance of showers, mainly after 2 a.m.

Tuesday’s forecast includes a 50% chance of showers with mostly cloudy skies and a low around 52. Northeast winds will be around 17 mph with gusts as high as 31 mph. Rain continues at night with a 50% chance of showers with a low around 52 and mostly cloudy skies, the weather service said.

On a mostly cloudy Wednesday, a 30% chance of showers is forecast with a high in the mid-60s. Conditions dry off at night, but partly cloudy skies remain with a low around 53.

The temperature warms up for a sunny Thursday with a high near 72. Partly cloudy skies with a low in the mid-50s is the nighttime forecast. On Friday, mostly sunny conditions with a high near 72 are forecast. Temperatures dip at night to around 47 with partly cloudy skies.
