Hurricane Maria Forecast To Bring Impacts To East Coast

Hurricane Maria will approach the Mid-Atlantic coast early this week then finally shove eastward into the open Atlantic. Maria will likely not make landfall but will come close to portions of North Carolina midweek and could bring tropical storm force winds, locally heavy rain, storm surge, and very rough surf. Maria will create hazardous surf and rip currents for much of the East Coast this week. Read More >
