Much of the nation was wetter than average during July, with the exception of the Northwest and Upper Mississippi River Valley. Increased monsoonal flow in the Southwest caused widespread precipitation and limited wildfire activity across the region. Several large wildfires burned in Alaska, where the month as warm and dry, creating ideal wildfire conditions. Over the course of July, drought conditions changed little in the drought-stricken West, despite the above-average rainfall. Parts of the Southern Rockies and Southern Plains did experience some drought improvement. As of July 30th, over 20 percent of Alaska was experiencing drought conditions, with a small portion of central Alaska in severe drought.
