215 WHUS43 KGRR 281946 CFWGRR LAKESHORE HAZARD MESSAGE National Weather Service GRAND RAPIDS MI 346 PM EDT Thu Jun 28 2018 MIZ037-043-290400- /O.NEW.KGRR.BH.S.0005.180629T2000Z-180630T0600Z/ Mason-Oceana- 346 PM EDT Thu Jun 28 2018 ...BEACH HAZARDS STATEMENT IN EFFECT FROM FRIDAY AFTERNOON THROUGH LATE FRIDAY NIGHT... The National Weather Service in Grand Rapids has issued a Beach Hazards Statement...which is in effect from Friday afternoon through late Friday night. * HIGH WAVE ACTION... STRONG CURRENTS AND DANGEROUS SWIMMING CONDITIONS EXPECTED. * STRONG STRUCTURAL CURRENTS EXPECTED. * STRONG LONGSHORE CURRENTS EXPECTED. * RIP CURRENTS POSSIBLE. * LOCATION...BEACHES FROM THE MUSKEGON OCEANA LINE NORTH THROUGH MASON COUNTY. * OVERVIEW/POTENTIAL IMPACTS...Southerly winds will increase into the 15 to 25 mph range on Friday which will build waves into the 3 to 5 foot range north of Whitehall. The beaches of Mason and Oceana Counties will likely see 3 to 5 foot waves and strong longshore currents during the afternoon and evening period of Friday. The potential exists for dangerous swim conditions due to stronger winds and higher waves continuing into the weekend. PRECAUTIONARY/PREPAREDNESS ACTIONS... High Wave Action makes swimming difficult and can tire even a strong swimmer quickly. Structural currents form along piers where longshore currents and wave action flow into the structure. Structural Currents can sweep you out into deeper water along the pier structure. A longshore current is a lake current that moves parallel to shore. Longshore currents can be strong enough to Prevent swimmers from being able to keep their feet on the bottom... making it difficult to return to shore. Rip currents are powerful channels of water flowing quickly away from shore...which occur most often at low spots or breaks in sandbars. Rip currents can sweep you into deeper water. && $$ WEATHER.GOV/GRR DUKE
