... Coastal Flood Warning remains in effect from 6 PM this evening
to 6 PM EST Friday...
... High surf advisory remains in effect from 6 PM this evening to
6 PM EST Friday...
A combination of strong high pressure building from the north and
remnants of Ida off the southeast coast... will allow an extended
period of strong onshore flow to develop along the Virginia and
Maryland coasts.
The approaching new phase of the moon... in tandem with the strong
onshore flow... will lead to increasing tidal anomalies of around
2 ft above normal... beginning this afternoon. Tidal departures
then building to 3 to 4 ft above normal from tonight through
Friday afternoon. This will likely result in moderate to
significant coastal flooding... with the greatest threat for
flooding coming with the Thursday and Friday high tide cycles.
High tides will be between 300 am and 500 am EST Thursday
morning... and 330 PM to 530 PM EST Thursday afternoon over the
warning area.

imminent. Coastal residents in the warned area should be alert
for rising water... and take appropriate action to protect life
