Global storm activity of 2007 profiles the major worldwide storms, including blizzards, ice storms, and other winter events, from January 1, 2007 to December 31, 2007. Winter storms are events in which the dominant varieties of precipitation are forms that only occur at cold temperatures, such as snow or sleet, or a rainstorm where ground temperatures are cold enough to allow ice to form (i.e. freezing rain). It may be marked by strong wind, thunder and lightning (a thunderstorm), heavy precipitation, such as ice (ice storm), or wind transporting some substance through the atmosphere (as in a dust storm, snowstorm, hailstorm, etc.). Other major non winter events such as large dust storms, Hurricanes, cyclones, tornados, gales, flooding and rainstorms are also caused by such phenomena to a lesser or greater existent.
Very rarely, they may form in summer, though it would have to be an abnormally cold summer, such as the summer of 1816 in the Northeast United States of America. In many locations in the Northern Hemisphere, the most powerful winter storms usually occur in March and, in regions where temperatures are cold enough, April.
A low pressure brought up heavy snow and blizzard conditions across the Canadian Prairies. Snowfall locally reached between 8 inches (20 cm) to 1 foot (30 cm) in parts of Alberta, Saskatchewan and Manitoba. Particularly hard-hit was central Saskatchewan, including the city of Saskatoon. The storm was accompanied by strong gusty winds in excess of 40 mph (64 km/h). Two people were killed during the blizzard when their car was stuck near a First Nations reserve in Saskatchewan. Saskatoon's Diefenbaker Airport as well as schools were closed.
