Winter Storm WarningExpandCollapse

When any of the following is expected within the next 12 to 36 hours

More than one predominant hazard

Winter weather event having more than one predominant hazard {ie. heavy snow and blowing snow (below blizzard conditions), snow and ice, snow and sleet, sleet and ice, or snow, sleet and ice} meeting or exceeding warning criteria for at least one of the precipitation elements.

Snow and/or Sleet

7 inches averaged over a forecast zone
Depending on impacts, a combination of precipitation elements may be considered in issuing Winter Storm Warnings.

Blizzard WarningExpandCollapse

Sustained winds or frequent gusts ≥ 35 mph AND considerable falling and/or blowing snow frequently reducing visibility < ¼ for ≥ 3 hours.
Blizzard conditions need to be the predominant condition over a 3 hour period.

Ice Storm WarningExpandCollapse

½ inch or greater accretion of freezing rain in any forecast zone.

Winter Weather AdvisoryExpandCollapse

When any of the following is expected within the next 12 to 24 hours

More than one predominant hazard

Winter weather event having more than one predominant hazard (i.e., snow and ice, snow and sleet, or snow, ice & sleet) meeting or exceeding advisory criteria for at least one of the precipitation elements, but remaining below warning criteria.

Snow and/or Sleet

4 inches averaged over a forecast zon

Snow and Blowing Snow

Sustained or frequent gusts of 25 to 34 mph accompanied by falling and blowing snow occasionally reducing visibility to ≤ ¼ mi for < 3 hours

Blowing Snow

Widespread or localized blowing snow reducing visibility to ≤ ¼ mi with winds < 35 mph

Freezing Rain

Any accretion of freezing rain or freezing drizzle on road surfaces.

Black Ice

A Special Weather Statement will usually be issued when sufficient moisture is expected to cause a thin layer of ice on road surfaces, typically on cloudless nights ("black ice"). At forecaster discretion a formal Winter Weather Advisory may be issued instead.

This is typically used for the approach of the eyewall of a major landfalling hurricane.

Flash Flood WarningExpandCollapse

Rapid and extreme flow of high water into a normally dry area, or a rapid water level rise in a stream or creek above a predetermined flood level, beginning within a short time-frame from the onset of heavy rain.

A dam or levee failure, or water released from an ice jam is also considered.

Winds sustained or with frequent gusts ≥ 25 mph
Relative Humidity at or below 30% anytime during the day
Rainfall amounts for the previous 5 days less than 0.25 inches (except 3 days in pre-greenup)
