Typical snowfall in St. Landry Parish, LA

NOAA's 30-year normal for St. Landry Parish: 0 in. of snow a year, from the EUNICE, LA US station. 27 mi is a real gap between St. Landry Parish and its nearest reporting station, so local snowfall can diverge from this figure, especially near elevation changes. (fresh vs. packed vs. ice explains why.)

What this St. Landry Parish figure assumes

This is a county-level reference figure for a typical heated home built to Risk Category II (ordinary residential), on a partially exposed lot - the assumptions ASCE 7-22 itself treats as the default case. A steeper roof, a fully exposed hilltop lot, an unheated structure, or a higher risk category all change the actual number.

St. Landry Parish's permit office wants an address-specific figure, not this county average - the ASCE 7 Hazard Tool is free, takes under a minute, and outputs a PDF most reviewers accept. See the methodology guide.
