A significant heat dome is anticipated to reach its peak in the Southwestern United States this weekend, causing temperatures to soar 10 to 20 degrees above average historical levels, thereby heightening the risks of wildfires and flash floods. Palm Springs, California, is projected to hit 120°F, while Phoenix is likely to come close to that figure by Sunday. Strong winds in the Northwest are predicted to escalate wildfire threats, and thunderstorms could lead to flash flooding across the Rockies and Great Basin. Authorities are advising residents to remain hydrated, limit outdoor activities, and stay alert to evolving weather updates into early August.
