High Surf Advisory Statement as of 4:36 PM EDT on July 23, 2008

... High surf advisory in effect from 8 am Thursday to 8 am EDT
Friday...

The National Weather Service in Taunton has issued a high surf
advisory... which is in effect from 8 am Thursday to 8 am EDT
Friday.

South winds will increase late tonight and Thursday with gusts to 25
to 30 knots possible. The increasing wind wave and swell will result
in seas building up to 8 feet on the outer waters during Thursday.
This will produce high surf and a high risk of strong rip currents
for ocean exposed south facing beaches on Thursday.

The greatest risk will be for the beaches west of Marthas Vineyard
as the higher seas will be building from the west.

High surf will persist Thursday night.

A rip current... sometimes mistakenly called an undertow... is a
strong but narrow current of water flowing from the beach to the surf
zone. It can rapidly carry a swimmer into deeper water and exhaust an
individual trying to swim against it.

If you are a poor swimmer and are caught in a rip current... swim
parallel to the beach until out of its pull. Another means of
escape for those who are good swimmers is to ride the current out
beyond the surf zone where the rip current dissipates... then swim
toward shore outside the effect of the narrow rip current.

Do not attempt to swim back to shore directly against the
current... it can exhaust and drown even the strongest swimmer.

Heed the advice of the beach patrol and swim only at guarded
beaches. Watch your children. Be especially cautious near piers
and jetties where rip currents can be enhanced.
