After days of recurring storms, as much as a month's worth of rain is expected to fall over southwestern Ontario today, and much of southern part of the province is under a flood watch as a result.

The situation isn't as grave as it was in southern Alberta just a week ago, mainly because there's no Rocky Mountains for this weather system to try to climb. However, forecasters are calling for up to 50 mm of rainfall today from this slow-moving weather system (which is about as much as the city of Kitchener-Waterloo typically gets for the entire month of June), with rainfall warnings issued from the central shores of Lake Erie up to the Bruce Peninsula. The rest of the province will be seeing rain as well, but so far the amounts aren't expected to get up to that warning threshold.

Now, that's only about 2 inches of rain, which may not seem like a lot, but just like what happened in Alberta, it all comes down to how much versus how long. With this 'small' amount of rain falling over an equally 'small' amount of time, you're already going to have some issues with how much the ground can soak up. Add to that the fact that Ontario has seen persistent recurring storms over the past several days, which means that the ground is already nearly saturated, and so most of that water is going to end up flowing directly into streams and rivers, which is why the Ministry of Natural Resources has issued a flood watch for most of southern Ontario.

So, should residents of southern Ontario be heading for higher ground?

No. There's no reason to panic. It could cause problems. It could cause flooding. That's why they're keeping an eye on the situation.

Apparently we're just getting the northern tip of this weather system, and it's New York State that's getting it much worse. Still, pack an umbrella today, check back here for updates, and, as always, be careful out on the roads.
