Sea fog impacts possible tonight into tomorrow

Sea fog (outlined) on the GOES-East visible image a little after 4PM.

With our stretch of ridiculously warm temperatures — the high so far today is 77° — comes the risk for sea fog development as the warmer air heads over much cooler water (~60°). As winds slacken tonight, we should see the fog close in on coastal communities (including downtown Charleston and perhaps beyond). Be ready for commute disruptions tomorrow morning due to dense fog; a Dense Fog Advisory is in effect until 9am for Charleston County as well as portions of Berkeley County in the tidal zone (think Daniel Island).
