Toronto and GTA Brace for Special Weather Alert with 20mm Rainfall

Environment and Climate Change Canada has issued a special weather statement for Toronto, the GTA and southern Ontario. Forecasters expect 10 to 20 millimetres of rain through Thursday. The advisory was issued Wednesday.

Toronto and the GTA are bracing for a special weather alert as up to 20mm of rainfall is expected. Scattered thunderstorms with heavy downpours are forecast this afternoon and again Thursday morning.

Thursday afternoon will bring showers and possibly more thunderstorms. The agency warned the ground is near saturation and has limited capacity to absorb more rain.

Portions of the region saw significant totals over recent days. Additional rainfall could produce flooding and other impacts in vulnerable areas.

Pooling on roads and in low-lying areas is likely, officials say. Rainfall warnings may be issued for some regions.

Impacts and cautions

Motorists should expect standing water and reduced visibility. Avoid driving through flooded areas and follow posted detours.

  • Avoid driving through standing water.
  • Slow down in heavy rain and low visibility.
  • Move valuables from basements and low spots.
  • Monitor local forecasts and warnings.

Forecast through Friday

The GTA is expected to start drying on Friday. Morning clouds should clear to afternoon sun. Daytime highs will be in the upper teens.

Fog advisory

Several areas, including Toronto, had a yellow fog advisory earlier. That advisory has since been lifted.
