Hurricane Dorian is back to a Category 2 storm with 110 mph winds. It is cutting within 50 miles of the South Carolina coast this afternoon and still expected to make landfall in North Carolina. The size of the storm’s expanded wind field is why a Tropical Storm Warning has been expanded into southern Maryland. While conditions will impact parts of the Chesapeake Bay, the wind direction is critical for water impact. See the local forecast maps for wind and waves below.
