Definition: Pogonip is freezing fog, formed by fine ice crystals floating in the air. It is a fairly common phenomenon in the Reno / Tahoe area during cold temperatures after a heavy snowfall. Pogonip results from a combination of high humidity and below freezing temperatures. It can be quite thick, making for hazardous driving conditions. On the plus side, pogonip frequently covers everything with a beautiful layer of fine ice crystals. Pogonip is from the Shoshone word meaning "cloud." Another interpretation is that it means "white death," which is what can happen to people who become helplessly lost in the fog and expire from exposure.
Pronunciation: po-go-nip
Examples:
