Tropical Storm Nicole is moving across west-central Florida on Thursday, with strong winds, dangerous storm surge and heavy rain continuing to threaten residents. 

The storm weakened after making landfall as a Category 1 hurricane along the east coast of the Sunshine State, just south of Vero Beach. 

However, the dangers were far from over, with tornado advisories issued by the National Weather Service for Florida and parts of Georgia. 

The agency's Melbourne office tweeted that storm surge warnings remained in effect and that there had been numerous reports from "all coastal counties" of erosion and flooding of coastal roadways.

The main threats include strong-to-tropical-storm-force winds and gusts, storm surge and heavy rain.

Rainfall of 2-3 inches was forecast in the region, with isolated higher totals. 

The office also cautioned residents of coastal erosion, felled trees and scattered power outages.
