The remnants of Hurricane Priscilla are expected to bring significant rainfall across the Southwest this weekend, prompting flood watches from Las Vegas to Salt Lake City. Areas north and east of Phoenix are particularly vulnerable, with forecasts predicting rainfall totals exceeding two inches in some locations. This deluge promises to alleviate the drought conditions plaguing the region, substantially reduce the risk of wildfires, and usher in cooler temperatures. Residents can anticipate highs dropping from the 90s into the more comfortable 80s.
