The National Weather Service is adding "Particularly Dangerous Situation" wording to select Blizzard Warnings and Ice Storm Warnings for the upcoming winter season. The designation is applied to events expected to pose an exceptional threat to life and critical infrastructure.
Why it matters
The wording signals rare, high-confidence events where extreme winter weather poses an exceptional threat to life and infrastructure. Residents across the United States may encounter the stronger language in warnings issued during the coming season.
Ice Storm Warnings are declared when 1/4 inch or more of ice accumulation is expected. The source does not state how often the new wording will be used across the country.
