In stark contrast to areas farther east and south, heavy precipitation was dropped on parts of the Pacific Northwest and the northern Intermountain West. Much of the Idaho Panhandle and adjacent parts of Montana reported heavy precipitation, with the highest elevations measuring up to 4 inches. Farther west, heavy precipitation also soaked the Cascades, and the Pacific Coast from Washington southward to northwestern California. Most of these areas – including lower elevations between the Cascades and the coastal areas – recorded at least 1.5 inches of precipitation while parts of the higher elevations were covered by 4 to locally 8 inches of precipitation. Patches of improvement were introduced as a result, with D3 removed entirely from central Washington, and spotty reductions in the D0 to D3 coverage across Oregon and northwesternmost California. With large sections of the central and southern parts of the West Region already in D3 to D4, not much more deterioration can be introduced, but a few small areas deteriorated enough to be reflected on the map, specifically north-central Utah (to D2), interior northeastern Utah (to D4), and southeasternmost New Mexico along the Mexican border (to D4).
