Categorical Thresholds (First Graphic)
None No winter weather is expected during the period.
General A light mix of precipitation or flurries is expected. However, no accumulations or hazards to motorists are anticipated.
Minor Accumulations are expected to be very light (less than 1/2" of snow, or a trace of ice/sleet) and will be primarily a nuisance to motorists. Bridges, overpasses, and elevated highways may be susceptible to icing.
Moderate Moderate accumulations (< 1/10" of ice, < 2" of snow, or < 1/2" of sleet) are expected. Many roads will be slick and ice-covered. Motorists are urged to exercise extreme caution. Bridges, overpasses, and elevated highways will be especially hazardous.
High Significant accumulations of snow (> 2"), ice (> 0.25"), sleet (> 1/2"), or mixed precipitation are expected. Major highways will be snow or ice-covered and travel will be extremely hazardous. Secondary roads, along with bridges, overpasses, and elevated highways, will be virtually impassable. Scattered power outages are also likely.
Severe Severe winter storm anticipated with large accumulations of snow (> 4"), ice (> 0.25"), or mixed precipitation. Travel will be severely limited if not impossible. Power outages may also affect a significant portion of the area.
