A Winter Storm Watch is issued by the National Weather Service of the United States when there is a potential for heavy snow or significant ice accumulations. The watch is usually issued 12 to 48 hours before the storm's arrival in the area. As is true with a Winter Weather Advisory, the criteria for this watch can vary from place to place. If Strong winds are expected with reduced visibilities, a winter storm watch may be upgraded to a Blizzard Watch.
A similar warning is issued by Environment Canada's Meteorological Service of Canada offices.
A winter storm is an event in which the varieties of precipitation are formed that only occur at low temperatures, such as snow or sleet, or a rainstorm where ground temperatures are low enough to allow ice to form (i.e. freezing rain). In temperate continental climates, these storms are not necessarily restricted to the winter season, but may occur in the late autumn and early spring as well. 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.
Snow
Snowstorms are storms where large amounts of snow fall. Two inches (5cm) of snow is enough to create serious disruptions to traffic and school transport (because of the difficulty to drive and maneuver the school buses on slick roads). This is particularly true in places where snowfall is not typical but heavy accumulating snowfalls can occur. In places where snowfall is typical, such small snowfalls are rarely disruptive, because of effective snow and ice removal by municipalities, increased use of four-wheel drive and snow tires, and drivers being more used to winter conditions. Snowfalls in excess of 6 inches (15cm) are usually universally disruptive.
January 31 – February 2, 2011 North American blizzard
The January 31 – February 2, 2011 North American winter storm, also called the 2011 Groundhog Day Blizzard, was a powerful and historic winter storm, situated around the United States and Canada on Groundhog Day. The storm is the most recent winter storm to rank as a Category 5 on the Regional Snowfall Index. During the initial stages of the storm, some meteorologists predicted that the system would affect over 100 million people in the United States. The storm brought cold air, heavy snowfall, blowing snow, and mixed precipitation on a path from New Mexico and northern Texas to New England and Eastern Canada. The Chicago area saw between 1 and 2 feet of snow and blizzard conditions, with winds of over 60mph. With such continuous winds, the Blizzard kept going north and affected Eastern and Atlantic Canada. The most notable area affected in Canada was Toronto and the Greater Toronto Area. Blizzard conditions affected many other large cities along the storm's path, including Tulsa, Oklahoma City, Kansas City, St. Louis, Springfield, El Paso, Las Cruces, Des Moines, Milwaukee, Detroit, Indianapolis, Dayton, Cleveland, New York City, New York's Capital District, and Boston. Many other areas not normally used to extreme winter conditions, including Albuquerque, Dallas and Houston, experienced significant snowfall or ice accumulation. The central Illinois National Weather Service in Lincoln, Illinois issued only their fourth blizzard warning in the forecast office's 16-year history. Snowfall amounts of 20 to 28inches were forecast for much of Northern and Western Illinois.
At sea, a storm warning is a warning issued by the National Weather Service of the United States when winds between 48 knots (89km/h, 55mph) and 63 knots (117km/h, 73mph) are occurring or predicted to occur soon. The winds must not be associated with a tropical cyclone. If the winds are associated with a tropical cyclone, a tropical storm warning will be substituted for the storm warning and less severe gale warning. In US maritime warning flag systems, a red square flag with a black square taking up the middle ninth of the flag is used to indicate a storm warning (the use of two such flags denotes a hurricane force wind warning or a hurricane warning). The same flag as a storm warning is used to indicate a tropical storm warning.
Example
The following is an example of a storm warning issued by the National Weather Service office in Seattle, Washington.
Storm Watch is a movie released in 2002, directed by Terry Cunningham and starring Adrian Paul and Bai Ling, the music was composed by Sean Murray. The movie centers on a protagonist who plays a virtual realityonline game, which suddenly turns into a race against time to stop a weather satellite from destroying the world. This film was released on DVD and VHS under the title Code Hunter.
Storm Watch features special effect scenes reused from Virus, End of Days, and Set It Off. Clips from Virus include the alien energy hitting the Russian ship (in Storm Watch, it is lightning hitting a decommissioned ship the Army uses for a target); and the "Sea Star" tug boat caught in the storm (shot to be a natural storm, in this film it is artificial). The entire subway train miniature exteriors are from End of Days. The Chevrolet Impala car chase was lifted from Set It Off.
