Advisory
(Abbrev. ADVY)- Highlights special weather conditions that are less serious than a warning. They are for events that may cause significant inconvenience, and if caution is not exercised, it could lead to situations that may threaten life and/or property.

Watch
A watch is used when the risk of a hazardous weather or hydrologic event has increased significantly, but its occurrence, location, and/or timing is still uncertain. It is intended to provide enough lead time so that those who need to set their plans in motion can do so.

Warning
A warning is issued when a hazardous weather or hydrologic event is occurring, is imminent, or has a very high probability of occurring. A warning is used for conditions posing a threat to life or property.

Storm
Any disturbed state of the atmosphere, especially affecting the Earth's surface, and strongly implying destructive and otherwise unpleasant weather. Storms range in scale from tornadoes and thunderstorms to tropical cyclones to synoptic-scale extratropical cyclones.

Blizzard
(abbrev. BLZD)- A blizzard means that the following conditions are expected to prevail for a period of 3 hours or longer:

Sustained wind or frequent gusts to 35 miles an hour or greater; and
Considerable falling and/or blowing snow (i.e., reducing visibility frequently to less than ¼ mile)

What is Wind Chill?
It is the temperature it "Feels like" outside and is based on the rate of heat loss from exposed skin caused by the effects of wind and cold. As the wind increases, the body is cooled at a faster rate causing the skin temperature to drop. Wind Chill does not impact inanimate objects like car radiators and exposed water pipes, because these objects cannot cool below actual air temperature.

What is Frostbite?
Frostbite is an injury to the body caused by freezing body tissue. The most susceptible parts of the body are the extremities such as fingers, toes, ear lobes, or the tip of the nose. Symptoms include loss of feeling in the extremity and a white or pale appearance. Medical attentions is needed immediately for frostbite. The area should be SLOWLY re-warmed.

What is Hypothermia?
Hypothermia is abnormally low body temperature (below 95 degrees Fahrenheit). Warning signs include uncontrollable shivering, memory loss, disorientation, incoherence, slurred speech, drowsiness, and apparent exhaustion. Medical attention is needed immediately. If it is not available, begin warming the body SLOWLY.

Tips on how to dress during cold weather.
- Wear layers of loose-fitting, lightweight, warm clothing. Trapped air between the layers will insulate you. Outer garments should be tightly woven, water repellent, and hooded.
- Wear a hat, because 40% of your body heat can be lost from your head.
- Cover your mouth to protect your lungs from extreme cold.
- Mittens, snug at the wrist, are better than gloves.
- Try to stay dry and out of the wind.

279...280...281...282...283...285...287...288...41 4...and 416 through
tuesday evening...

.a high pressure center remains to our southeast...bringing a
steady stream of hot and dry air from the southwest into the
area. Some mid level moisture will ride atop this stream of dry
air at the surface creating favorable conditions for dry
thunderstorms today.

Dry thunderstorms could occur just about anywhere today. All
zones with critically dry fuels have been included in the warning as
it could be a very active day for fire starts. Humidity will
continue to be low...in the low teens with some in the single
digits...and very gusty and erratic winds are expected with the
thunderstorms.

The critical fire weather conditions will continue through
tuesday evening as a dry cold front approaches from the northwest.
Winds will be strong from the southwest ahead of the front with
perhaps some more isolated to widely scattered dry thunderstorm
activity in fwzs 280 281 285 283 288 and 279.
