...BEACH HAZARDS STATEMENT IN EFFECT FROM 3 PM UNTIL 8 PM CDT 
THIS EVENING...

The National Weather Service in Duluth has issued a Beach Hazards
Statement, which is in effect from 3 PM until 8 PM CDT this 
evening.

* LOCATIONS...Park Point and Wisconsin Point Beaches.

* TIMING...Winds over the waters near the Twin Ports will turn
  northeasterly late this afternoon and wind speeds will increase
  to 15 to 20 mph with gusts to 25 mph. The rip current risk will
  be high after this wind shift, likely around 3 PM.

* DANGEROUS SWIMMING CONDITIONS...Are expected along the Lake 
  Superior shoreline due to high wave action and strong rip 
  currents.

* HIGH WAVE ACTION...Can make swimming difficult on days such as 
  this. Incoming waves in rapid succession can tire a swimmer 
  quickly.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Rip currents are powerful channels of water flowing quickly away
from shore...which occur most often at low spots in sandbars...
near shoreline structures such as peninsulas or breakwalls...and
near river mouths.
