Blowing Snow/Snowfall InnisfilWeather.Com Information Supplied By Environment Canada. Blowing Snow When blowing snow is expected to reduce visibility to less than 1 km (<5/8 mile) but not necessarily meet the blizzard definition for duration and temperature, or if it is more local in nature, a Blowing Snow Warning or Special Weather Statement may be issued. Snowfall Heavy snowfall can paralyze a city and leave commuters stranded. It can collapse power lines, knock down trees and in the mountains it can lead to avalanches. The amount of snow which has fallen in the previous days or even the first snow after a long dry spell in winter can create additional safety concerns. A Snowfall Warning is issued when hazardous amounts are expected to fall over a 12- or 24-hour period. These amounts vary across the country due to topographical and climatic considerations. They range from five cm in 24 hours for parts of southwestern BC to 15, 20 and even 25 cm in 24 hours elsewhere. Snowfall warnings are not issued more than 12 to 24 hours in advance and in some regions a Winter Storm Watch may give advance notification to a warning. A Special Weather Statement may be issued for lesser amounts in special circumstances. Safety Tip: remember that a thin layer of snow offers less traction than a few centimetres. |
