Environment Canada has introduced a new color-coded weather alert system. This system uses yellow, orange, and red to show different levels of risk. According to meteorologist Gerald Cheng, the change aims to improve how weather risks are communicated to Canadians.
“We know this method is effective,” Cheng explained. “It’s also recommended by the World Meteorological Organization.” Other countries like the U.K., France, and South Africa have successfully used this approach. It helps people quickly grasp the severity of weather events.
Yellow alerts will be issued for common but hazardous weather occurrences. Orange alerts indicate potentially significant damage, while red alerts signal rare and life-threatening situations. For instance, past red alerts have been linked to major weather events, such as:
- The 1998 ice storm in Quebec and Ontario.
- January 2020’s record-breaking snowstorm in St. John’s, N.L.
- The severe flooding from November 2021’s atmospheric river in British Columbia.
The alert types remain unchanged: watches, advisories, and warnings. A watch means severe weather could develop, while warnings indicate that severe weather is happening or about to happen. Advisories are for less serious weather conditions, like light snow or fog.
Cheng emphasized the effort behind the scenes. “We are ensuring that our data is reliable and accurate,” he said. As Environment and Climate Change Minister Julie Dabrusin noted, “With the increasing frequency of extreme weather in Canada, clear and accurate alerts are more crucial than ever.”
According to a 2023 survey by Statistics Canada, about 75% of Canadians feel that timely weather alerts significantly enhance their preparedness during extreme weather. As more people rely on these updates, the new system promises to be a vital tool for safety.
In today’s world, where weather patterns are changing rapidly, the importance of clear communication cannot be overstated. The adoption of this color-coded system is a step toward better informing the public and helping individuals prepare for what lies ahead.
