* IMPACTS...Most roads remain passable. Flooding up to one foot
deep affects coastal roads on the North Shore from Salem to
Gloucester and Newburyport. Rough surf will cause flooding on
some coastal roads around the time of high tide due to
splashover. Roads remain passable. Low lying areas and roads
near Nantucket Harbor, including Easy Street, may experience
pockets of shallow flooding less than one foot deep. Roads
remain passable. Shallow pockets of flooding less than one
foot deep affect low lying areas in Provincetown, mainly near
the airport and Race Point Road. In Truro, flooding up to one
foot deep affects low lying areas near Pamet Harbor and along
the Pamet River. Dangerous swimming and surfing conditions and
localized beach erosion.
PRECAUTIONARY/PREPAREDNESS ACTIONS...
If travel is required, allow extra time as some roads may be
closed. Do not drive around barricades or through water of
unknown depth. Take the necessary actions to protect flood-prone
property.
Inexperienced swimmers should remain out of the water due to
dangerous surf conditions.
