...HIGH RIP CURRENT RISK IN EFFECT THROUGH THIS AFTERNOON...
...HIGH SURF ADVISORY IS CANCELLED...

The National Weather Service in Taunton has issued a High Rip
Current Risk, which is in effect through this afternoon. The High
Surf Advisory has been cancelled. 

* LOCATIONS...Eastern Essex, Barnstable, and Nantucket Counties in
  Massachusetts
 
* TIMING...Until 6 PM EDT this evening.

* SURF ZONE IMPACTS...There is a high risk of rip currents today
  due to leftover swell from departing Hurricane Dorian. 
 
* IMPACTS...Rip currents can quickly sweep people away from the
  shore.

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
calm, do not exhaust yourself and stay afloat while waiting for
help. If you have to swim out of a rip current, swim parallel to
shore and back toward the beach when possible. Do not attempt to
swim directly against a rip current as you will tire quickly.
