Freezing rain forced some schools to close Friday morning, while heavy rain had an impact on commuters in Montreal.

The freezing rain passed briefly over Montreal overnight but was quickly melted as temperatures warmed up.

That wasn't the case outside the city, where freezing rain forced some schools to close in the Laurentians and the Eastern Townships. Freezing rain is expected to continue falling north of the St. Lawrence River before changing to heavy rain later in the day.

Environment Canada has issued alerts for much of the province, saying a weather system from the Gulf of Mexico is going to inundate much of Quebec on Friday..

North of the city up to 80 mm could fall in some places, with Montreal predicted to get more than 20 mm of rain.

The temperatures will remain mild overnight Friday and Saturday during the day, dropping to an estimated -6 C on Saturday night.

The freezing rain was never expected to have much of an impact in the metropolis, but the City of Montreal was monitoring the weather closely, and teams spread abrasives Thursday evening.

Heavy rain flooding roadways

Transport Quebec has warned drivers that several roads are being flooded because water cannot drain through snowy, ice-clogged sewers.

On Highway 20 East, two lanes were closed early Friday near the exit for the Champlain Bridge, and in the westbound lanes of the Ville Marie tunnel.

Water was also accumulating on both sides of the Champlain Bridge on Highway 15 North.

Transport Quebec was dispatching crews to various locations to pump water off the roadways to ensure drivers remained safe.
