CHICAGO — Authorities say no one was injured when a glass panel fell several stories onto Chicago's famous Michigan Avenue shopping district.

The glass was part of a window sign at the Water Tower Place mall.

The National Weather Service says a wind advisory remains in effect for the city until 3 p.m. Forecasters say gusts could reach 45 miles per hour.
