Wet, warm and humid conditions are likely to continue Wednesday on Long Island.
After a morning surge of heavy rain, the National Weather Service said Nassau and Suffolk counties could expect a chance of showers and thunderstorms as late as 10 p.m.
The service's Upton office said some of the storms also could produce gusty winds.
Much of the day should be partly sunny with daily highs slight above 80 degrees, the service said.
Aside from a stray shower or thunderstorm during the day, News 12 Long Island meteorologist Rich Hoffman called for warm conditions and a south wind from about 11 mph.
For beachgoers, there's a high risk for rip currents at ocean beaches starting at noon and running through the evening hours.
Wednesday night cools slightly, as humidity levels drop, but again there is a chance for showers and thunderstorms before 10 p.m. Some storms could produce gusty winds, Hoffman said.
Overnight lows in the mid 60s are expected.
During the morning hours Wednesday, as heavy rain pummeled rush hour, the service issued a flash flood watch for both counties and a severe thunderstorm warning and flash flood advisory for Suffolk.
On Thursday, morning conditions should be clear and dry, giving way to mostly sunny skies, with daily highs near 80.
There is a 20 percent chance for showers Thursday night into Friday morning, the service said.
