The Southwest U.S. faces significant flood threats from Tropical Storm Priscilla and another storm, with heavy rains expected to cause flash flooding across Arizona, California, Nevada, Utah, and Colorado, exacerbated by climate change.
Over 10 million people in the Southwest U.S., including parts of Arizona, Nevada, and California, are under excessive heat warnings due to a heat dome causing temperatures to soar. Cities are mobilizing to protect vulnerable populations, and firefighters are on high alert for wildfires. Experts warn that such extreme heat events are becoming more frequent due to climate change.
The Southwest US, including parts of California, Nevada, and Arizona, is bracing for the first heat wave of the season with triple-digit temperatures expected. Excessive heat warnings are in effect, and record daily highs may be broken in cities like Phoenix and Las Vegas. Fire crews are on high alert due to increased fire risk, and local governments are enhancing measures to protect vulnerable populations from the extreme heat.
Hurricane Hilary is expected to bring a prolific amount of rainfall to parts of the southwestern US, including California, Nevada, and Arizona, potentially dumping more than a year's worth of rain. This has prompted the first-ever tropical storm watch for California. Hilary, currently a Category 4 hurricane, is forecasted to weaken before reaching Southern California but will still enhance heavy rainfall and increase flooding danger. The storm's impact could be significant, with the potential for multiple years' worth of precipitation falling in some of the driest parts of California. Flood watches have been issued, and there are concerns about oversaturated ground and overwhelmed waterways. Additionally, the Atlantic is also gearing up for increased tropical activity, with four separate areas of concern stretching across the basin.
