Types of Weather Alerts
Specific Emergency Situations - Severe Summer Storms
Weather alerts are issued by Environment Canada. The type of weather alert used depends on the severity and timing of the event:
- Special Weather Statements are the least-urgent type of alert. A special weather statement is issued to let people know that conditions are unusual and could cause concern.
- Watches alert you about weather conditions that are likely to cause a storm or severe weather, which could cause safety concerns.
- A Watch may be upgraded to a Warning as certainty increases about the path and strength of a storm.
- A Warning is an urgent message that severe weather is either happening or will happen. Warnings are usually issued six to 24 hours in advance, although some severe weather (such as thunderstorms and tornadoes) can happen suddenly, with less than a half hour's notice.
If a Storm Watch or Storm Warning has been issued by Environment Canada, listen to the radio or television, or check the Internet for information or instructions.
