Chicago residents were urged to exercise caution near Lake Michigan as a Lakeshore Flood Advisory was issued on Monday.
High winds were causing massive swells on the lake, with some waves reaching 6-to-9 feet. The winds, along with higher-than-normal water levels, caused the waves to overtake barriers and flood low-lying areas along the lake, prompting warnings and advisories from the National Weather Service.
A Lakeshore Flood Advisory was in effect until 9 p.m. Monday, with southeast winds gusting to 45 mph in some locations. The waves were expected to subside late in the evening, but could produce minor flooding along Cook County shorelines and on the lakefront bike path.
A Special Weather Statement was also issued for all of northern Illinois due to the high winds, which could create travel hazards for high profile vehicles on west-to-east roadways and could knock over loose outdoor items.
After a cold front moves through the area, winds should begin to calm, but temperatures will also drop as highs are only expected to reach the low-to-mid 50s on Tuesday.
