ALT Coastal Flood Advisories are in effect for Martha’s Vineyard and Nantucket late Thursday night and again late Friday night. Minor flooding is expected in Nantucket Harbor, Edgartown Harbor, Vineyard Haven, and Oak Bluffs with a storm surge of 1 to 1.5 feet and waves up to 8 feet on Nantucket Sound. A little more flooding is possible near Nantucket Harbor if the surge is closer to 2 feet. No significant flooding is expected elsewhere, though water levels could run higher than normal along both coasts. In addition, swell from Erin should result in dune and beach erosion on south facing shores late this week, especially on Martha’s Vineyard and Nantucket, which have had significant erosion over the past few winters from nor’easters.
