The following update is from ARRL:
Some 1.2 million residents of Florida, Georgia, and South Carolina were reported to be without power, and thousands have evacuated to shelters, where ham radio volunteers have been supporting communication.
As of 1200 UTC on October 8, Hurricane Matthew about 20 miles south-southeast of Charleston, South Carolina. Maximum sustained winds were 85 MPH, and the storm was moving northeast at 12 MPH. Hurricane Matthew has yet to make landfall.
The storm’s current projected path shows it looping around toward the east, opening up the possibility of a second strike on the Bahamas and Florida sometime next week, likely in a much-weakened state.
