Across much of the West, conditions worsened, driven by a deepening snow drought, limited precipitation, and above-normal temperatures that continued to undermine snowpack development. While some mountain snowfall occurred, amounts were generally modest and failed to keep pace with early February climatological accumulation rates, causing snowpack deficits to expand across much of the region.

The Intermountain West saw conditions intensified as snow accumulation continues to fall well short of what is expected this time of the year. Numerous SNOTEL sites reported SWE below the 15th percentile, with several stations registering the lowest SWE on record for early February. These snowpack deficits were compounded by limited recent precipitation, declining soil moisture, and below-normal streamflows, particularly across northern Idaho and western Montana and extending into central and southern Montana and Wyoming. Similarly, Colorado and Utah saw conditions deteriorate as SWE levels are well below the median level along with drier soil moisture.

Across southwestern Idaho, northern Nevada and into eastern Oregon, persistent warmth, scarce precipitation, poor low-elevation snowpack, and low streamflows led to the expansion of abnormally dry (D0) and moderate drought (D1) conditions as well as the introduction of severe drought (D2) along the Idaho-Nevada border. SNOTEL stations in the Owyhee, Independence and Snake Mountains are reporting SWE levels between the ninth percentile to the worst on record.

Along the Pacific Coast, centered over Oregon, abnormally dry (D0) conditions expanded into southern Washington and northwestern California as the mid-winter dry spell continues, with poor snowpack development, very low streamflows, and limited soil moisture recovery outside the highest elevations.

The only improvement across the West occurred in southern New Mexico, where precipitation from earlier storm systems continued to translate into measurable hydrologic response, supporting localized improvements and one-category improvements.
