NEW YORK (WABC) -- Fast-moving Hurricane Helene is advancing across the Gulf of Mexico threatening a "catastrophic" storm surge in northwestern parts of Florida as well as damaging winds, rains and flash floods hundreds of miles inland across much of the southeastern U.S.

After Helene makes landfall, the Eyewitness News AccuWeather Team says the storm will head north and west before stalling out around the Tennessee and Ohio River Valley.

Some of the moisture will make its way east sparking a chance for some showers in our area over the weekend.

Areas south and west of New York City will have a better chance of seeing moisture on Saturday into Sunday.
