"The wind may be strong enough at times to cause minor tree and building damage," the statement said.

"High winds may toss loose objects or cause tree branches to break. Be prepared to adjust your driving with changing road conditions."

Horizon Utilities said it was "all hands on deck" for repair crews, with additional crews being called in, as weather-related power outages are affecting more than 15,000 customers in the city.

A passersby reported that a glass door was shattered by flying debris at Jackson Square.
