Nome Census Area, AK Roof Snow Load - Case Study Area
What "Case Study" means for Nome Census Area
Nome Census Area sits in the mountain-west terrain where ASCE 7-22 §7.2 itself declines to give a contour figure - elevation changes too fast over short distances there for one number per county to mean anything. The code requires a site-specific study for a building here, not a look-up.
Nome Census Area, FIPS 02180, is home to 9,836 people - one of 386 US counties ASCE 7 itself routes around a map figure for.

How much it actually snows in Nome Census Area
Most winters bring Nome Census Area roughly 80.8 in. of snow - NOAA's normal at NOME MUNI AP, AK US, 41.5 mi off. That station is far enough away (41.5 mi) that local snowfall - especially at a different elevation or near a lake - can run noticeably higher or lower than this figure. (fresh vs. packed vs. ice explains why.)
Read this before you rely on it
Nome Census Area's number above is ASCE 7-22's default case, not a custom calculation: ordinary residential occupancy, heated, sited on ground that's neither fully sheltered nor fully exposed. Any one of those changing - pitch, exposure, heating, occupancy - moves the real figure.
Nothing here substitutes for an address-level number. Get one free, in about a minute, from the ASCE 7 Hazard Tool using your own coordinates rather than Nome Census Area's county-wide figure. Details: the calculation guide.
