Hazardous Weather Outlook Issued As Strong Storms Approach LI

The National Weather Service says there is a slight chance for strong to severe thunderstorms today across Long Island and they say an isolated tornado cannot be ruled out completely on parts of the island.

A hazardous weather outlook has been issued for northern Nassau County and northwestern Suffolk County where there is the highest chance of severe storms.

"The main threat is damaging winds," the outlook says. "An isolated tornado or waterspout is also possible."

More thunderstorms are in the forecast Thursday through Saturday.

There is a high risk of rip currents at all ocean facing beaches Wednesday. If you are in the ocean, swim near a lifeguard. If caught in a rip current, relax and float, and do not swim against the current. If able, swim in a direction following the shoreline. If unable to escape, face the shore and call or wave for help.
