Lakeshore Flood Advisory, Beach Hazard Statement
Issued: 3:56 AM EDT Jul. 22, 2019 – National Weather Service

... Lakeshore flood advisory in effect from noon today to 6 am EDT
Tuesday...
... Beach hazards statement remains in effect from noon EDT today
through late tonight...

The National Weather Service in Grand Rapids has issued a
Lakeshore flood advisory... which is in effect from noon today to
6 am EDT Tuesday.

* Winds... north 15 to 25 mph this morning and up to 30 mph this
afternoon.

* Waves... 3 to 5 feet this morning building to 5 to 7 feet this
afternoon.

* High wave action... strong currents and dangerous swimming
conditions expected.

* Strong structural currents expected.

* Strong longshore currents expected.

* Rip currents expected.

* Location... beaches from St. Joseph to Grand Haven

* beaches with particularly dangerous conditions include...

North Beach in South Haven... Holland State Park...

* overview and impacts... north winds of 15 to 25 mph this morning
may approach 30 mph this afternoon and evening. Winds of this
magnitude will likely build waves into the 5 to 7 foot range.
Waves of this height are dangerous to swimmers and strong
currents are expected as well. A high swim risk is expected on
Monday south of Grand Haven. North sides of north piers will be
dangerous places to swim given longshore currents intersecting
the piers in these locations creating strong structural currents
along them. Stay dry when waves are high.

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.

A Lakeshore flood advisory indicates that onshore winds will
generate flooding of low areas along the Lakeshore.
