The warm spring weather we had all been enjoying has gone away as Environment Canada warns of flash floods and downpours in Southern Ontario today. There are currently weather warnings in place for almost all of Southern Ontario, with each warning of either rainfall, freezing rain, or in some areas even snow.
In the GTA, the majority of these warnings are for rainfall. These are in place in Toronto, Hamilton, Halton-Peel, and York-Durham. In most of these cases, Environment Canada had previously issued special weather statements regarding the rain, but due to its severity upgraded those to official rainfall warnings.
Now the warnings say that significant rainfall is expected today, as we are expecting 20 to 40 mm of rain. They warn that "heavy downpours can cause flash floods and water pooling on roads. Localized flooding in low-lying areas is possible. Keep children and pets away from creeks and river banks."
Rainfall warnings are also in place for Niagara, Windsor, Waterloo, Simcoe, London, Kingston, and Belleville, but as you head further east and further north these warnings change over to freezing rain warnings and in some places even snowfall.
For instance, in Bancroft, Brockville, Ottawa, Peterborough, Cornwall, and Haliburton, Environment Canada warns of freezing rain, while in Haliburton and Algonquin they warn of snow.
In the freezing rain warnings, Environment Canada says that the colder air is causing the rain to change to snow and freezing rain throughout the day.
They also caution that "surfaces such as highways, roads, walkways and parking lots may become icy and slippery. Ice build-up may cause tree branches to break. Utility outages may occur."
The worst warnings, however, are the snowfall warnings in Algonquin and Haliburton, where Environment Canada warns that up to 20 cm of snow is likely to fall today.
While those are the only two areas with actual snow warnings the rest of Southern Ontario isn't off the hook. As the air gets colder tonight the rain in most places will likely change to snow.
For example, in Toronto, Environment Canada warns that there could be possible snow accumulations of 2 to 4 cm throughout the evening today.
If there is any good news here, it's that the miserable weather won't last forever. Temperatures are expected to rise into next week with sunshine and double-digit temperatures in the forecast in some areas by Tuesday and Wednesday.
