Coastal Flood Advisory
* WHAT...Up to one foot of inundation above ground level in low-
lying areas near shorelines and tidal waterways (4.0 to 13.0
feet Mean Lower Low Water).
* WHERE...The eastern MA coastline.
* WHEN...Until 2 PM EST Monday.
* IMPACTS...Shallow pockets of flooding less than one foot deep
affects the lowest lying areas along the coast, including
Morrissey Boulevard in Boston. 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 with
pockets of shallow flooding less than one foot deep. This
mainly affects low lying areas and roads near Edgartown
Harbor, including the Chappy Ferry Dock. Shallow flooding may
also approach Five Corners in Vineyard Haven.
* ADDITIONAL DETAILS...Two additional high tide cycles will result
in pockets of minor coastal flooding. The first is very late
tonight with the second around lunchtime Monday. Sub-freezing
temperatures and very cold road surfaces could allow storm surge
to freeze, prolonging impacts and delaying drainage after high
tide periods.
