A blizzard warning is an alert issued by the National Weather Service (NWS) indicating that severe winter weather conditions are either occurring or expected imminently. Specifically, it signifies that heavy snowfall combined with sustained winds or frequent gusts of at least 35 mph are anticipated to persist for a minimum of three hours, leading to visibilities reduced to 1/4 mile or less.
