Grant County, New Mexico
County storm and disaster record · FIPS 35017 · population 28,092 · 3,961 sq mi
NOAA's Storm Events Database holds 935 records for Grant County, New Mexico from 1950 through June 30, 2026, on 381 days; the most frequent are drought records (583 records). 763 of them are forecast-zone records, which the National Weather Service files once per zone: a county covered by several zones receives each one, so a single storm can add several records on the same day. The deadliest single record is the February 27, 2025 dust storm, filed for the forecast zone Southwest Desert/Lower Gila River Valley, which covers the county: 3 deaths. FEMA has issued 13 declarations naming the county since 1972, 11 of them for natural hazards; the latest for a natural hazard was “Trout Fire” on June 16, 2025.

Is it getting more frequent?
Records per decade for Grant County's most frequent hazards. Counts rose everywhere after 1996, when NOAA began recording every event type, so compare decades within a hazard's complete period only (the shaded cells come before it).
| Hazard | 1950s | 1960s | 1970s | 1980s | 1990s | 2000s | 2010s | 2020-26 |

High wind and dust storms in the 2010s: 30 records against 6 in the decade before, 30 of them forecast-zone records. Cells marked z rose mostly through zone records. The local National Weather Service office files these once per forecast zone, so a change in how it draws its zones or splits a storm into records moves this count as much as the weather does; read it beside the Grant County days with a record above.
