Hyde County, NC Roof Snow Load - 10 psf
Hyde County, NC roof snow load, translated
A typical heated home in Hyde County is designed to carry 10 pounds per square foot of snow on its roof, per ASCE 7-22. 7 psf is what the ground-load formula alone gives; Hyde County's 10 psf low-slope minimum (§7.3.4) beats it, so that figure is the one that governs on flat and low-pitch roofs.
On a roof that means 22 in. of fresh snow, 8 in. once it packs down, or 2 in. of solid ice - three very different piles for the same load. A modest addition to standard roof loading. Ordinary residential construction handles this without extra bracing.

FIPS 37095, population 4,583, centered near 35.4082°N 76.1537°W. ASCE 7's underlying ground snow load here is 10 psf before the code's exposure and importance factors bring it to the 10 psf design figure above.
Hyde County: average annual snowfall
Hyde County sees about 1.2 in. of snow most winters, per the BELHAVEN 3 NE, NC US station's 1991-2020 NOAA normal. That station is far enough away (26.8 mi) that local snowfall - especially at a different elevation or near a lake - can run noticeably higher or lower than this figure. See the density guide.

The figure above assumes the case ASCE 7-22 treats as typical: a heated, ordinary-occupancy home on a partially exposed site. Change any of those - exposure, heating, roof pitch, occupancy category - and the real design number moves.
