...HIGH RIP CURRENT RISK IN EFFECT FROM MONDAY MORNING THROUGH

VINEYARD, AND NANTUCKET...

The National Weather Service in Norton has issued a High Rip
Current Risk, which is in effect from Monday morning through
Monday evening. 

* LOCATIONS...Block Island, Marthas Vineyard, and Nantucket

* TIMING...Monday morning through Monday evening.

* IMPACTS...Very strong rip currents will be dangerous to
  anyone who enters the surf.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

There is a high risk of rip currents.

Rip currents are powerful channels of water flowing quickly away
from shore, which occur most often at low spots or breaks in the
sandbar and in the vicinity of structures such as groins, jetties
and piers. Heed the advice of lifeguards, beach patrol flags and
signs.

If you become caught in a rip current, yell for help. Remain
