News 12 Meteorologist Bill Korbel says wet weather is expected across Long Island overnight.
The National Weather Service has issued a coastal flood advisory for most of Nassau and western parts of Suffolk until Thursday at 2 a.m.
Korbel says there may even be a thunderstorm late tonight, and local street flooding is likely.
Heavy showers will end Thursday morning, and some afternoon sunshine with temperatures in the mid-60s is expected.
