On October 2, 2017, issuance of the blizzard watch has been discontinued. A winter storm watch is now issued in its place. Blizzard warnings continue to be issued, however.006-008-010>014-019>023-032-033-039-INZ001-002-010-011-019- 310145- /O.CAN.KLOT.WS.A.0001.110201T1800Z-110203T0000Z/ /O.NEW.KLOT.BZ.A.0001.110201T1800Z-110203T0000Z/ WINNEBAGO-BOONE-MCHENRY-LAKE IL-OGLE-LEE-DE KALB-KANE-DUPAGE-COOK- LA SALLE-KENDALL-GRUNDY-WILL-KANKAKEE-LIVINGSTON-IROQUOIS-FORD- L ...

Winter Storm Warning
A winter storm warning ( SAME code: WSW) is a hazardous weather statement issued by Weather Forecast Offices (WFO) of the National Weather Service (NWS) in the United States to alert the public that a winter storm is occurring or is about to occur in the area, usually within 36 hours of the storm's onset. A similar warning is issued by Environment and Climate Change Canada (ECCC) through local forecast offices of the Meteorological Service of Canada. Definition Generally, a Winter Storm Warning is issued if the following criteria, at minimum, are forecast: snow accumulations usually between or greater than , or snow accumulations of usually or more with significant accumulation of ice ( sleet or freezing rain). In the Southern United States, where severe winter weather is much less common and any snow is a more significant event, warning criteria are lower, as low as in the southernmost areas: as one goes from north to south, the accumulation estimates needed to meet warning crit ...

Winter Weather Advisory
A winter weather advisory (originally identified as a Traveler's Advisory until the 2002-03 climatological winter when officially renamed, and informally as such by some local television stations thereafter) is a hazardous weather statement issued by Weather Forecast Offices (WFO) of the National Weather Service in the United States when one or more types of winter precipitation—snow, rain and snow mixed, freezing rain, sleet, graupel, etc.—presenting a hazard, but not expected to produce accumulations meeting storm warning criteria (usually below 10 cm / 4 inches), are forecast within 36 hours of the expected onset of precipitation or are occurring in the advisory's coverage area. A Winter Weather Advisory is similar to a significant weather advisory, but a winter weather advisory is an official product and is specific to cold weather.

Most local weather offices will activate and broadcast the SAME alarm tone on relevant NOAA Weather Radio stations for both varieties of warning. When the Wireless Emergency Alerts system was launched in 2012, blizzard warnings were initially sent as alerts to mobile phones; this practice was discontinued in November 2013. In Canada, comparable warnings are issued by Environment and Climate Change Canada through the Meteorological Service of Canada (MSC).

Winter Storm Watch
A winter storm watch is issued by the National Weather Service of the United States when there is a possibility of heavy snow or potential of significant ice accumulations, without meeting a specific other winter criteria. The watch is typically issued 12 to 48 hours before the storm's expected arrival in the given area. The criteria for this watch can vary from place to place, which is true with other winter weather warning and advisories. As the event of the storm draws nearer in time and confidence in the occurrence of significant winter weather conditions and accumulation is increased, the weather watch will be upgraded to a winter storm warning or blizzard warning, depending on whether blizzard conditions will be met. If there is considerable confidence in significant ice accumulations with little to no snow, the watch will be upgraded to an ice storm warning. When confidence increases in the occurrence of winter like conditions that are not expected to reach warning or oth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
