With expected swells from Tropical Storm Bertha and surf height of 4 to 6 feet, a high rip-current risk is in effect for the Long Island oceanfront from Wednesday morning through evening, the National Weather Service said.
The rip-current risk runs from 6 a.m. to 8 p.m. Wednesday, the weather service said.
A small-craft advisory also is in effect for the waters off Long Island's South Shore from midnight to 6 p.m. Wednesday.
The tropical storm is forecast to move "north-northeastward well offshore of the U.S. mid-Atlantic coast," said the National Hurricane Center late Tuesday afternoon.
Wednesday afternoon into evening also brings about a 30 percent chance of scattered showers and thunderstorms -- not expected to be severe, said Joe Pollina, weather service meteorologist in Upton. That's resulting from an upper level disturbance that's not related to the tropical storm, he said.
As for temperatures, look for highs Wednesday in the low- to mid-80s, he said.
Thursday is expected to be dry and mostly sunny, with highs in the lower 80s, he said.
By Friday, high pressure will build to generate a clear, mostly sunny weekend, Pollina said.
