...HIGH SURF ADVISORY IN EFFECT FROM NOON TODAY TO 4 AM EDT
TUESDAY...
...HIGH RIP CURRENT RISK IN EFFECT FROM NOON EDT TODAY THROUGH
LATE TONIGHT...

The National Weather Service in Tampa Bay Ruskin has issued a
High Surf Advisory, which is in effect from noon today to 4 AM
EDT Tuesday. A High Rip Current Risk has also been issued. This
High Rip Current Risk is in effect from noon EDT today through
late tonight. 

* HIGH SURF...Increasing northwest winds will allow surf to build
  this afternoon to 3 to 4 feet at area beaches.

* HIGH SURF TIMING...High surf will develop this afternoon and
  will persist overnight.

* HIGH SURF IMPACTS...High surf may produce localized beach
  erosion and dangerous swimming conditions.

* RIP CURRENT TIMING...Strong gusty northwest will create
  increased wave action along the coast and will support a high
  risk of rip currents at area beaches today and tonight.

* RIP CURRENT IMPACTS...Strong rip currents will be hazardous 
  for those in the surf zone along area beaches. 

PRECAUTIONARY/PREPAREDNESS ACTIONS...

A High Surf Advisory means that high surf will affect beaches in
the advisory area...producing localized beach erosion and
dangerous swimming conditions.

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. For maximum safety...swim near a lifeguard.
Pay attention to 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.
