Low pressure will form this week in the western Atlantic Ocean, where it will move slowly and bring several coastal impacts to the Eastern Seaboard, including rough surf, coastal flooding, rain and wind. This future system is also being monitored by the National Hurricane Center for possible subtropical development.
The area of low pressure is forecast to develop well off the mid-Atlantic coast by Wednesday. It will then crawl northward and linger off the Northeast coastline through late this week.
Winds will persistently blow toward the mid-Atlantic and Northeast coasts between the counterclockwise flow around the area of low pressure and the clockwise flow around high pressure to its north.
That onshore wind will create several impacts along the Eastern Seaboard from mid- to late week. Details are still uncertain, but here's a general overview of what you can expect along parts of the Northeast coast from Wednesday into Saturday.
-Surf: Rough surf conditions and rip currents will likely impact the East Coast for an extended period. Some beach erosion and minor to moderate coastal flooding will also likely impact the mid-Atlantic and Northeast coasts.
-Rain: Periods of rain will pivot into the mid-Atlantic and Northeast coasts from Wednesday through late week. Parts of southeast New England could see the heaviest rainfall totals.
-Wind: The onshore flow mentioned earlier will likely create prolonged windy conditions near and just inland from the mid-Atlantic and Northeast coasts. The strongest winds with gusts greater than 40 mph are expected along the immediate coastline.
