Issued at 1144 PM MDT Sat Oct 31 2026- Heavier rainfall will return Sunday into Monday across western New Mexico. Given saturated soils, there is a chance for localized flooding from persistent rainfall. River rises are expected across northern and western NM and there is a moderate to high chance for river flooding.
- There is a low (5-15%) chance that severe thunderstorms will develop across eastern New Mexico Sunday night, bringing a threat for hail, damaging winds and tornadoes.
