Special weather statement
A Special weather statement is a form of weather advisory. Special weather statements are issued by the National Weather Service of the United States (the NWS) and the Meteorological Service of Canada (the MSC). There is no set criteria for special weather statements in either country.

[edit] United States
A special weather statement may be issued by the NWS for hazards that have not yet reached warning or advisory status or that do not have a specific code of their own, such as widespread funnel clouds. They are also occasionally used to clear counties from severe weather watches.[1] A common form of special weather statement is a significant weather alert. Occasionally special weather statements appear as heat advisories.

[edit] Canada
Special weather statements are issued by the MSC for weather events that are unusual or those that cause general inconvenience or public concern and cannot adequately be described in a weather forecast. These may include widespread events such as Arctic outflows, Alberta clippers, coastal fog banks, areas of possible thunderstorm development, and strong winds such as chinooks and les suetes winds. They are written in a free style and may also reflect warnings in effect near the United States border.
[edit] Example of a Canadian special weather statement
Special weather statement issued for regions of southern Manitoba by Environment Canada at 3:10 PM CDT Sunday 23 March 2008. Special weather statement issued for.. Minnedosa - Neepawa - Russell - Riding Mountain National Park Ste. Rose - McCreary - Alonsa - Gladstone Dauphin - Roblin - Winnipegosis. An Alberta clipper is forecast to enter western Manitoba early Monday morning giving 5 to 10 cm of snow to regions around the Riding mountains by Monday evening. The snow will give localized reduced visibilities and make travel difficult especially along the Yellowhead highway. These conditions will improve late Easter Monday as the clipper moves out of the area. Further details follow in the next regular public forecast At 4.00 PM CDT. END/BUKOSKI
