Good morning. *NOTE*: There is a correction for the marine seas graphic. A strong ocean storm will shift north well southeast of Cape Cod today, then will push west tonight before looping offshore on Friday. This storm will bring strong to damaging winds, increasing rough seas along with minor to moderate coastal flooding during Friday morning's high tide. With the expected increase of the wind and seas across eastern areas, headlines have been upgraded to warnings and advisories. Details are below. *Headlines:* - High Wind Warning*: *In effect from early Friday morning through Friday evening for Cape Cod, Nantucket and Martha's Vineyard. - *Wind Advisory*: In effect from early Friday morning through Friday evening for Cape Ann as well as eastern and southern Plymouth county - *Coastal Flood Warning*: In effect for Friday morning's high tide for Nantucket Harbor. - *Coastal Flood Advisory*: In effect for this morning's high tide for Nantucket Harbor. - *Coastal Flood Advisory*: In effect for Friday morning's high tide for east coastal Mass (*including the city of Boston*), Cape Cod and Martha's Vineyard. - Storm Warning: In effect early Friday morning thru Friday evening, for the coastal waters east of Ipswich Bay and Stellwagen Bank National Marine Sanctuary and the offshore waters adjacent Cape Cod and the Islands (excluding Buzzards Bay and Vineyard Sound). - *Gale Warning*: In effect early Friday morning thru Friday evening, for the remaining waters. *Details:* *Coastal Flooding: * *This Morning: Minor Coastal Flooding* - *Locations*: Nantucket Sound - *Timing*: From 6 AM to 10 AM. - *Impacts/Inundation*: Up to one foot of inundation above ground level in low-lying areas near shorelines. *Friday Morning: Minor to Moderate Coastal Flooding* - *Locations*: East coastal Mass, Cape Cod and the Islands. - *Timing*: From 6 AM to 10 AM Friday morning. - *Impacts/Inundation*: For Nantucket: One to two feet of inundation above ground level possible. For east coastal Mass including Cape Cod and Martha's Vineyard, up to one foot of inundation above ground level possible. - *Confidence and Uncertainty: *High confidence on coastal flooding, greatest confidence for minor structural damage for Nantucket. A storm track closer to the southern New England coast may further elevate the coastal flood threat. *Strong to Damaging Winds: * - *Locations: *Cape Cod and the Islands and east coastal Mass. - *Timing: *Northeast winds increase late tonight, with peak gusts Friday morning thru afternoon. - *Winds*: North wind gusts up to 60 mph for Cape Cod and the islands, and up to 50 mph for east coastal Mass. - *Impacts: *Possible downed trees and power lines. - *Confidence and Uncertainty*: Moderate to high confidence on gusts producing minor to moderate impacts across Cape Cod and the Islands. A closer storm track to coastal southern New England would expand the coverage of stronger northeast winds further inland. In that situation, strong winds capable of minor tree/powerline damage could be possible as far west as I-95. The attached graphics include current headlines in effect, the maximum wind gust and maximum wave height. Thank You! Meteorologist Eleanor Vallier-Talbot
