* WHAT...For the Coastal Flood Warning, up to one foot of
inundation above ground level in low-lying areas near
shorelines and tidal waterways (3.9 to 12.6 feet Mean Lower
Low Water). For the High Surf Advisory, large breaking waves
of 6 to 15 feet in the surf zone.
* WHERE...Eastern Essex MA, Suffolk MA, Eastern Norfolk MA,
Eastern Plymouth MA, Barnstable MA, Dukes MA and Nantucket MA
Counties.
* WHEN...Until 8 PM EDT Sunday.
* IMPACTS...Strong northeast winds with large waves will result
in minor coastal flooding with pockets of moderate coastal
flooding over multiple high tide cycles from late today
through the weekend. The water also may struggle to vacate the
area after the high tides given persistent strong northeast
winds. The greatest risk for coastal flooding appears to be
setting up south of Boston and onto the Cape and Islands. In
addition...the long duration of northeast winds coupled with
large waves over multiple high tide cycles will result in
areas of severe beach erosion for a prolonged period.

* WHAT...Flooding caused by excessive rainfall continues to be
possible.
* WHERE...Portions of Massachusetts, including the following areas,

Western Kent RI.
* WHEN...Through late Monday night.
* IMPACTS...Excessive runoff may result in flooding of rivers,
creeks, streams, and other low-lying and flood-prone locations.
Creeks and streams may rise out of their banks.
* ADDITIONAL DETAILS...
- Periods of rain will continue across the region right through
Monday. Storm total rainfall amount of 2-4" are expected, but
localized 5-7" amounts are possible. If these higher amounts are
realized...the potential for both urban and small river/stream
flooding would increase. This is particularly true if these
localized higher amounts occur over a vulnerable urban center.
