A heavy downpour across Toronto Thursday afternoon has flooded some of the arteries into and out of the city, which could make for a difficult commute home.

More than 42 millimetres of rain covered the central and western parts of the city at midday, flooding parts of the Don Valley Parkway, Eglinton Avenue, Black Creek Drive and the Bayview Avenue extension.

The city had closed Bayview south of Pottery and Rosedale Valley road between Bayview and Park Road, as well as the ramps from the DVP to northbound and southbound Bayview Avenue. Those all re-opened before 5 p.m.

Police also closed one of the southbound lanes on the DVP near Gerrard Street around 3:30 p.m.

Both Metrolinx and the TTC warned passengers to check their schedules as certain buses had been rerouted and flooding closed the Richmond Hill GO train line.

The storms and rain are expected to move out of the area as the afternoon goes on. Clear skies are expected return by the evening.
