(KRON) Hurricane Matthew sideswiped Florida’s Atlantic coast early Friday, toppling trees onto homes and knocking out power to more than 800,000 people but sparing some of the most heavily populated stretches of shoreline the catastrophic blow many had feared.

Authorities warned that the danger was far from over, with hundreds of miles of coastline in Florida, Georgia and South Carolina still under threat of torrential rain and deadly storm surge as the most powerful hurricane to menace the Atlantic Seaboard in over a decade pushed north.

They warned, too, that the storm could easily take a turn inland.
