Recently upgraded to a Category 4 storm, Hurricane Matthew is closing in on the Florida coastline at a steady 14 mph and is expected to make landfall Friday morning (~8:00 AM). Predicted storm tracks have Matthew moving up the eastern coast into the Carolinas before veering east back over the Atlantic. The below map illustrates storm tracking and modeled storm surge data from the National Hurricane Center, with potential height above ground for storm surge flooding in affected geographic regions.
