The Chicago National Weather Service Forecast Office issued a Beach Hazards Statement calling for dangerous rip and structural current from 1 a.m. Monday until late Monday night along the Illinois Lake Michigan shoreline (bluish-green-shaded area on the headlined map).
The hazard extends farther north along the Wisconsin shoreline up to just south of Sheboygan. Three to five-foot waves along the shoreline will make for the dangerous swimming conditions. The forecast includes strong to possibly severe thunderstorms with possible flood-producing downpours, vivid lightning and damaging winds add to the negative outlook for beach activity Monday.
Easterly winds will strengthen to 15 to 25 miles per hour driving 4- to 7-foot waves on the open waters of Lake Michigan, as a center of low pressure intensifies as it approaches from the west. As waves sweep in from the open waters, they will maintain 3 to 5-foot heights along the shoreline.
