Wind Chill Warning
A wind chill warning is a hazardous weather statement issued by local forecast offices of the National Weather Service (NWS) in the United States and previously by the Meteorological Service of Environment and Climate Change Canada (ECCC) when wind chills are forecast to reach values low enough for residents and travelers to be susceptible to life-threatening medical conditions (such as severe frostbite and hypothermia) or death associated with accelerated body heat loss. Extreme wind chills meeting Wind Chill Warning criteria can generate a significant decrease in body temperature, and induce frostbite damage to exposed skin and other tissue over an accelerated period of time (onsetting within as little as 10 to 15 minutes in severe cases). People within the warned area are advised to avoid venturing outdoors unless conducting necessary travel; if going outside, extra precaution should be taken against the likelihood of developing hypothermia and frostbite by wearing multiple laye ...

National Weather Service
The National Weather Service (NWS) is an agency of the United States federal government that is tasked with providing weather forecasts, warnings of hazardous weather, and other weather-related products to organizations and the public for the purposes of protection, safety, and general information. It is a part of the National Oceanic and Atmospheric Administration (NOAA) branch of the Department of Commerce, and is headquartered in Silver Spring, Maryland, within the Washington metropolitan area. The agency was known as the United States Weather Bureau from 1890 until it adopted its current name in 1970. The NWS performs its primary task through a collection of national and regional centers, and 122 local Weather Forecast Offices (WFOs). As the NWS is an agency of the U.S. federal government, most of its products are in the public domain and available free of charge. History Calls for the creation of a government weather bureau began as early as 1844, when the electrica ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Weather Warnings And Advisories
Weather is the state of the atmosphere, describing for example the degree to which it is hot or cold, wet or dry, calm or stormy, clear or cloudy. On Earth, most weather phenomena occur in the lowest layer of the planet's atmosphere, the troposphere, just below the stratosphere. Weather refers to day-to-day temperature, precipitation, and other atmospheric conditions, whereas climate is the term for the averaging of atmospheric conditions over longer periods of time. When used without qualification, "weather" is generally understood to mean the weather of Earth. Weather is driven by air pressure, temperature, and moisture differences between one place and another. These differences can occur due to the Sun's angle at any particular spot, which varies with latitude. The strong temperature contrast between polar and tropical air gives rise to the largest scale atmospheric circulations: the Hadley cell, the Ferrel cell, the polar cell, and the jet stream.

Arctic
The Arctic ( or ) is a polar region located at the northernmost part of Earth. The Arctic consists of the Arctic Ocean, adjacent seas, and parts of Canada ( Yukon, Northwest Territories, Nunavut), Danish Realm ( Greenland), Finland, Iceland, Norway, Russia ( Murmansk, Siberia, Nenets Okrug, Novaya Zemlya), Sweden and the United States ( Alaska). Land within the Arctic region has seasonally varying snow and ice cover, with predominantly treeless permafrost (permanently frozen underground ice) containing tundra. Arctic seas contain seasonal sea ice in many places. The Arctic region is a unique area among Earth's ecosystems. The cultures in the region and the Arctic indigenous peoples have adapted to its cold and extreme conditions. Life in the Arctic includes zooplankton and phytoplankton, fish and marine mammals, birds, land animals, plants and human societies. Arctic land is bordered by the subarctic.

Atlantic Canada
Atlantic Canada, also called the Atlantic provinces (french: provinces de l'Atlantique), is the region of Eastern Canada comprising the provinces located on the Atlantic coast, excluding Quebec. The four provinces are New Brunswick, Newfoundland and Labrador, Nova Scotia, and Prince Edward Island.

The provinces combined had an approximate GDP of $121.888 billion in 2011. The term ''Atlantic Canada'' was popularized following the admission of Newfoundland as a Canadian province in 1949. History The first premier of Newfoundland, Joey Smallwood, coined the term "Atlantic Canada" when Newfoundland joined Canada in 1949. He believed that it would have been presumptuous for Newfoundland to assume that it could include itself within the existing term " Maritime provinces," used to describe the cultural similarities shared by New Brunswick ...

Southern Ontario
Southern Ontario is a primary region of the province of Ontario, Canada, the other primary region being Northern Ontario. It is the most densely populated and southernmost region in Canada. The exact northern boundary of Southern Ontario is disputed; however, the core region is situated south of Algonquin Park, the latter being in an area of transition between coniferous forest north of the French and Mattawa Rivers and southern deciduous forest. It covers between 14 and 15% of the province, depending on the inclusion of the Parry Sound and Muskoka districts which also lie in the transitional area between northern and southern forest regions. With approximately 13.5 million people, the region is home to approximately 36% of Canada's population of 37.0 million. Southern Ontario differs greatly from Northern Ontario, in that it has a much higher population density, a different climate, and a different culture than its northern counterpart. It is broken into smaller subregion ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Extreme Cold Warning
An extreme cold warning is issued by Environment Canada to inform the public about active or imminent severe cold temperatures in their region that are expected to last for at least two hours. As of April 8, 2014, Environment Canada replaced the Wind Chill Warning with an Extreme Cold Warning. In the older system a wind chill warning for Southern Ontario and Atlantic Canada was issued when the wind chill dropped to -35. Thus a temperature of with no winds would not require a warning be issued. Under the new system the extreme cold warning is issued based on either the temperature or the wind chill being a certain value for at least two hours. The values range from in the warm temperates to in parts of the Arctic. Ranges for issuing an extreme cold warning An extreme cold warning is issued when the following temperatures are expected to last for at least two hours, which different regions have different criteria for: *South-Central Ontario and Southwestern Ontario issued at ...

Wind Chill Advisory
A wind chill advisory 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 wind chills are forecast to reach values low enough that it poses a threat to human health and life if adequate protection is not taken against hypothermia and frostbite. The exact criteria meriting the issuance of an advisory varies from state to state, and areas prone to colder temperatures will often require the wind chill to be lower before issuing an advisory. Example The following is an example of a wind chill advisory issued by the National Weather Service office in Detroit, Michigan. 920 WWUS43 KDTX 212131 WSWDTX URGENT - WINTER WEATHER MESSAGE NATIONAL WEATHER SERVICE DETROIT/PONTIAC MI 431 PM EST FRI JAN 21 2011 ...EXTREME COLD WIND CHILLS TONIGHT... .COLD TEMPERATURES IN ADDITION TO WINDS INCREASING TONIGHT AHEAD OF A LOW PRESSURE SYSTEM WILL ALLOW WIND CHILLS TO DROP BETWEEN -15 AND -20 A ...
