Hermine lingers off shore continuing its unsafe storm surges
A tropical storm warning was in effect from New York's Long Island to Massachusetts.
Long Island authorities urged people to evacuate the summer getaway known as Fire Island to avoid any storm surge and coastal flooding.
Hermine rose up over the Gulf of Mexico and hit Florida on Friday as a Category 1 hurricane before weakening to a tropical storm across Georgia.
Emergency managers issued mandatory evacuations for some low-lying mobile home parks and apartment buildings.
The storm was centered about 305 miles (490 kilometers) southeast of the eastern tip of Long Island.
Since sea levels have risen up to a foot due to global warming, the storm surges pushed by Hermine could be even more damaging, climate scientists say.
