Suffolk County has declared a state of emergency as Tropical Storm Hermine moves closer to the area.

Suffolk authorities are calling for Fire Island residents to voluntarily evacuate as the storm nears.

"South Shore communities as well as barrier communities in the Town of Babylon have the ability to drive off their locations if necessary. That is not an option in most cases here on Fire Island-- which is why we are making this call to give people enough time to put their things together and debate their decision to evacuate," said Bellone.

Meanwhile, Nassau County Executive Ed Mangano on Saturday issued a storm surge warning to residents in areas prone to flooding. He urged people in those areas to be prepared, review evacuation routes, assemble "go-kits" and finalize shelter plans in case bad flooding makes evacuations necessary.

Both Nassau and Suffolk counties are under a tropical storm warning until further notice.

Gov. Andrew Cuomo says that ocean beaches on Long Island will be closed to swimmers starting Sunday due to strong riptides from the storm.

The storm is expected to stall for the next several days over the Atlantic Ocean about 150 miles south of Long Island, bringing coastal flooding, strong winds and beach erosion to the Island.
