Hurricane Matthew has moved on to the Carolinas and is currently hitting the South Carolina coast with powerful winds, heavy rain, and dangerous storm surge. The most intense part of the storm is expected to hover near or on the coast of South Carolina throughout Saturday, moving into North Carolina Saturday night.

The National Hurricane Center reports that Matthew is now a Category 1 storm with sustained winds of 85 mph, though higher gusts are still being measured. While the storm is now somewhat less powerful than the 140-mph Category 4 monster it was Thursday, it continues to threaten severe floods in Georgia, South Carolina, and North Carolina, adding to the damage it's already caused in Florida and Georgia.

As the National Weather Service points out, decreased winds do not mean the storm is less dangerous. Storm surge and flash flooding caused by rain are responsible for more than 75% of hurricane deaths in the US.

In Savannah, the storm surge — the sea level rise and subsequent flooding due to hurricane-force winds — could break records:

Just after 2 pm Friday, footage began to come in of a major storm surge in Jacksonville, Florida. A video shared on Facebook by user Bradley Hatcher captures a particularly dramatic angle:

As the Washington Post reports, the first news of severe flooding arrived before noon on Friday. Twitter posts show dangerous floodwaters in St. Augustine and Daytona Beach. The St. Augustine sea wall has "vanished under the waves."
