[Weather] NWS Boston Emergency Management Briefing [9/21 PM] - Significant Marine Event Tue

[BOX Operations - NOAA Service Account]

Good afternoon

No significant changes to the track of Hurricane Teddy.  The storm is still
expected to pass about 400 miles east of Massachusetts Tuesday night.

The main impact will be for the Marine community.  High confidence in high
seas of 15 to 25 feet on the outer waters east and southeast of Cape Cod
and the Islands. Northerly winds will gust 40 to 50 kt in this area.  A
Storm Warning is in effect on these waters, while a Gale Warning is up on
most other waters.  Block Island Sound, Narragansett Bay, and Boston Harbor
have Small Craft Advisories.

Pockets of minor coastal flooding & beach erosion appear likely during the
Tuesday afternoon high tide cycle along the eastern MA coast and
particularly across the north facing sides of Cape Cod and Nantucket. While
some typically vulnerable shoreline roads may become flooded within a few
hours of the high tide, significant coastal flooding is not expected. High
surf & dangerous rip currents are expected on ocean exposed beaches.  In
addition, given the large surf, viewing the large waves or fishing from
jetties and/or piers can be very dangerous and is strongly discouraged.  A
Coastal Flood Advisory is in effect during Tuesday afternoon for the
Massachusetts eastern coasts including Nantucket and Marthas Vineyard.

Northerly wind gusts of 40 to 50 mph are likely across Cape Cod and
Nantucket Tuesday, thus a Wind Advisory remains in effect. No rain is
expected from Hurricane Teddy in southern New England.

We have attached the expected track of Hurricane Teddy along with our
current wave height and wind gust forecasts.
