...LAKESHORE FLOOD ADVISORY REMAINS IN EFFECT UNTIL 4 PM EDT
SATURDAY...
...BEACH HAZARDS STATEMENT IN EFFECT FROM 8 AM EDT SATURDAY
THROUGH SATURDAY EVENING...

The National Weather Service in Detroit/Pontiac has issued a
Beach Hazards Statement for dangerous swimming conditions on
Saturday. The Lakeshore flood advisory also remains in effect
through Saturday afternoon. 

* Lake Shore Flooding...North to northeast winds of 15 to 25 knots
  will continue into Saturday. This wind is expected to produce 3
  to 5 foot waves with occasional waves to 7 feet.

* High Wave Action and Dangerous Swimming Conditions Expected.

* Location...Beaches from Caseville to Port Huron including...

Caseville...Sand Point...Port Crescent State Park...   Port
Austin...Harbor Beach...Port Sanilac...Lexington...   Birch
Beach...Lakeport...Fort Gratiot...Port Huron...

* Impacts...The high water level combined with the high wave 
  action will have potential to result in minor shoreline 
  flooding and erosion. Damage to docks, boat lifts, or 
  watercraft anchored along the shoreline will also be possible. 
  These winds and waves will also lead to dangerous swimming 
  conditions. 

PRECAUTIONARY/PREPAREDNESS ACTIONS...

A Lakeshore Flood Advisory indicates that onshore winds will
generate flooding of low areas along the lakeshore.

High wave action alone can also make swimming difficult on days
such as this. Incoming waves in rapid succession can tire a
swimmer quickly.

* Prepare, plan and stay informed. Visit www.weather.gov/safety
