High Surf Advisory Statement as of 3:35 am EDT on July 9, 2008

... High surf advisory in effect from 4 PM this afternoon to 8 am
EDT Thursday...

The National Weather Service in Taunton has issued a high surf
advisory... which is in effect from 4 PM this afternoon to 8 am
EDT Thursday.

High surf will produce dangerous rip currents along south facing
beaches this afternoon through tonight.

Persistent southwest flow has resulted in seas up to 5 feet over the
waters just south of Block Island and Marthas Vineyard. As southwest
winds increase today... seas over the offshore waters will build up to
7 feet later today.

The southwest winds will push these higher seas toward the South
Coast with high surf developing this afternoon through tonight. Surf
heights along south coastal beaches will increase up to 5 feet. This
high surf will result in a high risk of dangerous rip currents
developing this afternoon for south facing beaches.

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.
