Southern Ontario has been issued Wind and Heavy Rainfall Warnings by Environment Canada. Heavy rains are expected tonight and winds gusting as high as 90 km/h are expected on Saturday afternoon into the evening.
Earlier today, Toronto along with most of southern Ontario was issued heavy rainfall warnings starting tonight and continuing into Saturday with rainfall amounts of 20 to 40 mm. Now on top of the rain comes high wind gusts up to 90 km/h, so those considering outdoor activities like putting up Christmas lights or going for a hike, skate or stroll, may want to reconsider or get out there earlier in the day before the high winds sweep through.
With all the rain making its way towards us, apparently a result of a strengthening low pressure system tracking northeast across the Great Lakes on Saturday, Environment Canada warns that heavy downpours can cause flash floods and water pooling on roads.
On top of the heavy rain, the wind gusts come courtesy of a cold front will sweep through southern Ontario Saturday afternoon and evening.
Of course the high winds mean utility outages could possibly occur along with damage to buildings, such as to roof shingles and windows. Strong winds also may toss loose objects or cause tree branches to break.
And if you must venture out on the roads tonight – to get to that hockey game, dance recital or cheerleading competition, perhaps – be prepared to adjust your driving with changing road conditions due to high winds.
Environment Canada warns that during the heavy rains may cause localized flooding in low-lying areas is possible. Area residents are also advised to watch for possible washouts near rivers, creeks and culverts.
Compiling the issue, to the north of the GTA in the snowbelt region, the somewhat frozen ground has a reduced its ability to absorb this rainfall and melting snow will contribute to excessive runoff.
For those headed north, the rain is expected to fall as freezing rain as the temperatures drop.
