JONES BEACH - Thousands of Long Islanders grabbed their umbrellas and sunscreen to mark Labor Day at the Island's beaches today, even though many are under a rip current warning.

"When you go from high tide to low tide, the intensity of the rip tide increases and people get pulled back and they don't realize it ? that's when they panic and by then they're getting rescued by the lifeguards," says Lt. Eddie Costigan, of the Jones Beach Lifeguard Corps.

Many Long Island beaches reopened just in time for the holiday. Some were forced to close last week after Hurricane Irene created dangerous waves, caused some coastal erosion and scattered debris along the sand. Storm-battered LI beaches prepping for Labor Day LI beaches endure beating from Irene
