At this time, severe thunderstorms would have been tracking across those regions in red. Watches (yellow) and warnings (red) are indicated across southern Saskatchewan on this sample Public Weather Alerts Map from Environment and Climate Change Canada. Thus, a severe thunderstorm watch could be in effect for much of the day, and then it is replaced by a severe thunderstorm warning as the storms pop up on radar. First a watch is issued, and this is followed by upgrading those watches to warnings as the storms or tornadoes develop. When conditions advance past simply having the potential for severe weather, and severe weather is actually developing or occurring, forecasters issue a Warning.Įxactly when a warning is issued usually depends on what kind of weather is expected.įor severe thunderstorms and tornadoes, the ideal goal is to follow a specific progression, of course. Credit: ECCCĮssentially, any conditions that would certainly affect someone's day, but are not expected to develop to the point where they would qualify as severe weather. This special weather statement was issued in southwestern Ontario, on June 20, 2018, due to the potential for hot and humid weather that was expected to give rise to conditions of poor air quality. This is a text statement, giving forecasters a chance to explain unusual conditions or weather of concern that a region may soon experience - heavy rainfall, thunderstorms, strong winds, and/or high humidex values. When active weather is expected or occurring, but there's no current indication that conditions will be severe or extreme, Environment Canada issues a Special Weather Statement. Specifically, and track and evaluate their forecasting accuracy.With the approach of summer, forecasters will be on the lookout for more outbreaks of severe weather, and when extreme weather looms in Canada, there is a progression of statements, watches and warnings issued to inform and protect the public.
