Potentially deadly waves and rip currents are expected to impact beaches and waterfront areas across five U.S. states, prompting the National Weather Service (NWS) to issue beach hazard alerts. Authorities are urging the public to stay out of the water due to these dangerous conditions.
In the Midwest, Indiana, Illinois, Michigan, and Wisconsin are anticipating dangerous rip currents and waves reaching up to nine feet. These conditions are expected to persist until at least Tuesday night. Major cities situated along Lake Michigan, including Chicago and Milwaukee, are likely to experience significant beach disruptions. The NWS has warned that high waves can swamp piers and sweep individuals out to sea, making swimming conditions life-threatening. In response, two dozen beaches in Chicago have already implemented a ban on swimming unless a lifeguard is present.
The hazardous weather in the Great Lakes region is attributed to a cold front passing through the area. This front, combined with persistent northerly winds blowing across Lake Michigan, is causing wave heights to increase and powerful currents to form along the shore.
Similar warnings are in effect for California, where nearly the entire coastline, from San Diego to San Francisco, is under alert. Waves are forecast to reach up to 10 feet, accompanied by dangerous rip currents and potential coastal flooding. These hazardous conditions are expected to continue until Wednesday night.
The disturbance along the California coast is caused by a long-period swell originating from the south and southwest. These waves, which have traveled over long distances across the Pacific, are larger and more powerful than usual. Upon reaching the coast, they generate bigger breaking waves, sudden sneaker waves that can surge unexpectedly far up the beach, and strong currents capable of pulling swimmers into deeper water.
