Information Supplied By Environment Canada. Dust Storm A warning is generally issued only in the Prairie Provinces when blowing dust caused by high winds is expected to reduce visibility to one kilometre or less for one hour or more. Dust can impair breathing for people and animals, and make travel hazardous. Dust storms can develop suddenly in the form of an advancing dust wall that may be kilometres long and hundreds of metres high. The most severe dust storms occur in the summer and are often associated with downdrafts generated by thunderstorms or cold frontal passages. While the life span of the storm may last several hours, a local area that it passes over will feel the impact for only 15 to 30 minutes. Dust Storm Warnings are not issued more than 12 hours in advance. Safety Tip: If you must go out, breathe through a wet face cloth. |
