This advisory is issued when a winter storm of significance is occurring, imminent, and is an inconvenience.

Winter Storm Watch

This watch is issued when significant winter weather is expected, but not imminent. This usually comes from 12 to 36 hours prior to the possibility of severe winter weather. It notifies of heavy snow, heavy sleet, significant freezing rain, or a combination. When this watch is issued, it usually will mean that it is time to prepare for the warning to come, usually by stocking up on emergency supplies and knowing what to do if the warning is issued.

Winter Storm Warning

A significant winter storm, or hazardous winter weather, is occurring, imminent, or likely. The storm is a threat to life and property. This warning means that it is not safe to travel, or venture out. If you are traveling, seek nearby shelter.

Blizzard Warning

In order for this type of warning to be issued, winds will be at least 35 mph (miles per hour) or great. Snow will be blowing and therefore reducing visibility to 1/4 mile or less for a time period of at least three hours. Dangerous wind chills are also expected in the warning area.

Is it Freezing Rain, or Sleet?

Freezing rain is rain droplets that can freeze upon contact with the ground. The droplets will create a smooth, clear, and icy coating on surfaces.

Sleet is frozen precipitation that is falling in the form of transparent pellets of ice.
