(CNN) Post-Tropical Nestor quickly crossed over the Florida Panhandle Saturday afternoon and moved on to bring high winds and heavy rain to parts of the Southeast.

The storm raked portions of south Georgia with wind and rain and is forecast to hit South Carolina later Saturday and Sunday.

By Sunday evening, a few counties in Georgia were under tornado warnings, and there were reports of a tornado in central Georgia.

At 5 p.m. ET, Nestor's winds were 40 mph, down from maximum sustained winds of 60 mph Friday evening, the National Hurricane Center said in its last advisory on the storm. The storm was downgraded by the hurricane center to a post-tropical cyclone earlier on Saturday.

The storm made landfall on Florida's St. Vincent Island Saturday afternoon after pounding parts of the Florida Gulf Coast with heavy rain, strong winds and storm surges, and spawned tornadoes in the Tampa Bay area.
