- Where: Lake Michigan beaches in Sheboygan and Ozaukee Counties.
- Timing: Through Wednesday morning.
What the NWS says to do
- Stay out of the water.

Quick “beach signs” reminder (E. coli vs. waves/currents)
Sheboygan County health signs/flags use green (Good), yellow (Caution), and red (Closed) based on E. coli water-sample posting rules. That’s a separate issue from this NWS warning, which is about waves and dangerous currents. For Wednesday morning plans, follow the NWS stay-out guidance through the stated time window.
