Foehn wind to greater daytime radiative (solar) warming under foehn conditions. This type of warming is particularly important in cold regions where snow or ice melt is a concern and/or avalanches are a risk. Winds of this type are also called "snow-eaters" for their ability to make snow and ice melt or sublimate rapidly. This is a result not only of the warmth of foehn air, but also its low relative humidity. Accordingly, foehn winds are known to contribute to the disintegration of ice shelves in the polar regions. Foehn winds are notorious among mountaineers in the Alps, especially those climbing the
Weather warning [increasing] significantly, but its occurrence, location, and/or timing is still uncertain"" and a warning as ""hazardous weather or hydrologic event [that] is occurring, is imminent, or has a very high probability of occurring"" . Additionally, the NWS breaks down weather warnings and watches based upon the specific type of hazardous weather. These warnings and watches include, but are not limited to, flooding, severe local storms, tropical cyclones, and winter storms. In Canada, governmental weather warnings and watches are issued by the Environment Canada. Non-governmental alerts, not watches or warnings, such as a "rotation detected" or "tornado reported" are issued by
