Weather Wednesday – Floods

Hi all and welcome to another Weather Wednesday.I am going to try and talk about flooding and or flash flooding.
In the Greater Toronto Area we don’t get many severe deluges of rain but yesterday in Burlington Ontario, the rain god’s decided to stop by and visit. Unfortunately the nearest Weather Radio transmitter was not working so those who listened to Weather Radio had to rely on Ham Radio or the internet, along with local radio and TV stations for current severe weather watches and warnings.
Last July Toronto had its own flood event and my apartment building was affected but not enough to impede my movement. However, the same couldn’t be said for people on a Go Train on the Richmond Hill line. They had to be rescued by boats and I’m sure that wasn’t fun for them.
I wonder if this is a trend for flood events to happen each year, once or twice a spring, summer or fall in Canada. For some reason these events happen when it isn’t steaming hot and they are generally unexpected. If a really bad rainfall event happens, are we really prepared for it, like they are in British Columbia? Their rainfall warning criteria is 100 mm in less than 24 hours in the summer and 50 mm of rain in less than 24 hours in winter. Those are the criteria for a rainfall warning. In Ontario it’s 50 mm in the spring summer and fall and 25 mm in the winter. I wonder if that will be amended in the next couple of years, because of these severe rainfall events.
If you have any comments you can reply here or email me at and I will get back to you.
Also, for more weather stuff you can subscribe to my Weather Radio Listeners Newsletter mailing list by emailing me at and I will send you all the issues so far. You will also receive the next issue when it comes out.
Another blog you may want to follow alongside this one is from Phil Chadwick. He is a retired meteorologist from Environment Canada and his specialty was severe weather. Here is the url.
Check it out if you are a weather nut. He has stuff in there that I didn’t even know. Well, after all, he did work for Environment Canada for many years and he retired in 2011.
Well, that’s it for today’s blog post. Talk to you on Sunday.
