Seasonal Drought Outlook is based on recent conditions, forecasts at various time scales throughout the outlook period, and climatology.ĭrought is very likely to persist in much of the West, from California, northern Nevada, and western Montana westward to the Pacific Coast. Much of Yellowstone Park experienced flooding and mudslides with heavy rainfall in June, closing parts of the Park at times. Rainfall was excessive in parts of Montana, western North Dakota, and northern Wyoming. Drought also eased somewhat across the Ohio Valley, the adjacent Midwest, and northern portions of the Rockies and High Plains. In contrast, a robust monsoon season in the Southwest provided some drought relief, and brought flooding into parts of Arizona and New Mexico. Much of the Northeast, parts of the Southeast, and much of the Northwest also received less than normal rainfall and patchy areas of drought expansion and intensification. Excessive heat was most persistent over this same region, leading to significant drought expansion and deterioration.ĭryness was less acute and not as widespread farther north, but significantly below-normal rainfall also affected much of the central and northeastern Great Plains and the upper Mississippi Valley, where there were areas of deterioration.
