Strong winds, high surf, rip currents, coastal flooding and beach erosion will add up to a prolonged nuisance along parts of the Southeast coast through this weekend.
This coastal threat will occur in two rounds.The first round will take place in the wake of a powerful arctic front on track to set hundreds of mid-November cold records in the U.S.
Behind that front, strong northeast winds will howl over the Atlantic Ocean off the Southeast U.S. coast Tuesday night through Thursday.
These onshore winds will whip up waves and push them toward the coast from the northern Outer Banks of North Carolina and southeast Virginia to Florida's Atlantic beaches. In addition, the full moon Tuesday will make higher tides higher and lower tides lower as the pull of gravity from the sun and moon combine on Earth's oceans.The high tide of peak concern appears to be Wednesday morning, with moderate coastal flooding possible in both downtown Charleston, South Carolina, and near Tybee Island, Georgia.
Minor flooding is possible along the northeast Florida coast and St. Johns River Basin, according to the National Weather Service.Beginning Friday, forecast models have an interesting setup along the East Coast.Strong high pressure will settle into the Northeast behind a reinforcing Canadian cold front. At the same time, low pressure is expected to develop somewhere near or off the Southeast coast. These two features could hang in place for a few days.The contrast between the high and low pressure systems will again drive persistent strong winds near the Southeast coast.Strong winds blowing over the ocean for a long time will generate significant waves. The waves will be pushed toward the coast from Florida at least to the Virginia Tidewater this weekend, generating more high surf, rip currents and coastal flooding.
