    Here's your weather briefing for Wednesday, September 24. 

    1. Winds pick up in Newfoundland tonight

    High pressure in place for most of the Maritimes Wednesday with seasonal temperatures and calm winds expected.

    In Newfoundland however, powerful winds are forecast Wednesday night.

    "Newfoundland will be seeing breezy conditions today and picking up tonight on the north peninsula," Grinter says. "Gusts up to 110 km/h are possible."

    "Damage to buildings, such as to roof shingles and windows, may occur. Loose objects may be tossed by the wind and cause injury or damage," said Environment Canada in a wind warning issued Wednesday morning.

    2. High pressure dominates in Ontario

    "High pressure will remain in place until next week," says Grinter. "Temperatures will increase into the weekend with humidex values into the high 20s on both Friday and Saturday."

    Parts of northwestern Ontario are at risk of seeing some scattered showers today.

    3. Summer heat persists in the Prairies

    "Warm temperatures continue to be the main story with the possibility of a few 30°C temperatures in through the southern Prairies Wednesday," Grinter says. "There's an even greater chance of temperatures into the 30's on Thursday."

    Next chance for precipitation through Alberta?

    "Not until Thursday overnight into Friday," Grinter adds.

    4. Heavy rain hits the south coast of B.C.

    "A strong Pacific front will continue to bring rain heavy at times to the South Coast," said Environment Canada in a rainfall warning issued for Metro Vancouver Tuesday night. "Rainfall amounts of 50 mm are expected for Howe Sound and near the Northshore in Metro Vancouver by early Wednesday."

    The heaviest rain will begin to ease Wednesday morning as the front moves out of the region, but another front will bring more rain with amounts up to 20 mm in Howe Sound through Wednesday, EC adds.

    "Heavy downpours can cause flash floods and water pooling on roads," EC warns.

    "Gusty winds will also continue along the western side of Vancouver Island," Grinter adds.
