...BEACH HAZARDS STATEMENT IN EFFECT THROUGH LATE TONIGHT...

* WHAT...Rough choppy surf and a southward flowing longshore
  current in the surf zone today. A low risk of dangerous rip
  currents exists, especially near piers and jetties.

* WHERE...Coastal Volusia, Coastal Indian River, Coastal Saint 
  Lucie, Coastal Martin, Mainland Northern Brevard, Northern 
  Brevard Barrier Islands, Mainland Southern Brevard and 
  Southern Brevard Barrier Islands Counties.

* WHEN...Through late tonight.

* IMPACTS...Breezy northwest winds will produce a moderate
  southward flowing longshore current today, which can push
  swimmers into deeper water unexpectedly, and make them more
  susceptible to dangerous rip currents.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Swim near a lifeguard. If caught in a rip current, relax and
float. Don't swim against the current. If able, swim in a
direction following the shoreline. If unable to escape, face the

...COASTAL FLOOD WATCH IN EFFECT FROM LATE TONIGHT THROUGH
SATURDAY AFTERNOON...

* WHAT...For the High Rip Current Risk, dangerous rip currents 
  expected. For the High Surf Advisory, large breaking waves of 
  5 to 13 feet expected in the surf zone. For the Coastal Flood 
  Watch, significant coastal flooding possible.

* WHERE...Coastal Volusia, Coastal Indian River, Coastal Saint 
  Lucie, Coastal Martin, Mainland Northern Brevard, Northern

* WHEN...For the High Rip Current Risk, through this evening. 
  For the High Surf Advisory, from 10 PM this evening to 1 PM 
  EST Saturday. For the Coastal Flood Watch, from late tonight 
  through Saturday afternoon.

* IMPACTS...Low lying property including homes, businesses and
  some critical infrastructure may be inundated. Shoreline erosion
  may occur. Dangerous swimming and surfing conditions and
  localized beach erosion at time of high tide. Rip currents can 
  sweep even the best swimmers away from shore into deeper water.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Conditions favorable for coastal flooding are expected to
develop. Coastal residents should be alert for later statements
or warnings and take necessary actions to protect flood-prone
property.

High surf will affect the beaches in the advisory area, producing
localized beach erosion and dangerous swimming conditions.
Swimmers should remain out of the water due to large breaking
waves and dangerous surf 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 jetties and
piers. Heed the advice of lifeguards, beach patrol flags and
signs.

Entering the water is not recommended. If caught in a rip 
current, relax and float. Don't swim against the current. If able,
swim in a direction following the shoreline. If unable to escape,
face the shore and call or wave for help.
