(UPDATED) Remnants of Ernesto heading up the eastern seaboard may cause heavy rain, wind and possibly coastal flooding across Westport and the tri-state region this holiday weekend, the National Weather Service said tonight.
As of late this evening, the center of Tropical Depression Ernesto was located over the east coast of central Florida. The center of the storm will move northward into the Atlantic Ocean overnight.
The forecast calls for Ernesto to restrengthen to a tropical storm tonight before making another landfall near Charleston, S.C., Thursday afternoon. Ernesto will then weaken to a depression as it moves further inland across North Carolina and Virginia Friday, an evening advisory said.
Such a movement, according to the National Hurricane Center, is expected to bring the remnants of Ernesto into Pennsylvania during Saturday.
Since the tri-state region will become sandwiched between a very strong high pressure system centered over southeastern Canada and the remnants of Ernesto moving northward along the coastal plain, winds will begin to pick up across the tri-state area as early as Friday, the advisory said.
Winds by Saturday may be gusting between 30 and 35 mph. These winds will be from the northeast Friday and then gradually shift around to the southeast during Saturday.
This onshore flow will likely pile water up along the Long Island Sound coastline. As such, tidal departures will rise and may result in some minor to locally moderate coastal flooding beginning as early as the high tide cycle Friday afternoon.
The more likely cycle to see problems will be Saturday afternoon.
In addition, seas will build and become quite rough—conditions ideal for the development of dangerous rip currents.
The rough surf would also offer a threat of splash-overs and beach erosion, especially along the South Shore of Long Island, the statement said.
In addition, rain preceding Ernesto may edge into the tri-state region Friday night and become heavy at times during Saturday.
If heavy rains do occur across the area, some widespread urban and small stream flooding is possible. Flooding along larger rivers would be a possibility as well.
Residents of the tri-state region, especially coastal residents and mariners, should continue to monitor the latest forecast and plan holiday weekend activities accordingly, the advisory said.
