Sudden Heatwave to Impact California and Arizona with Extreme Temperatures
A sudden heatwave is set to affect California and Arizona, with temperatures forecasted to soar as high as 114°F (46°C). This unseasonably high heat, more typical of peak summer than early May, has prompted warnings from the National Weather Service (NWS) and health experts. Extreme heat warnings and advisories have been issued for areas including Phoenix, Imperial Valley, the Salton Sea region, Yuma, and the Coachella Valley. In addition to the heat, air quality alerts are in effect, compounding health risks for millions of residents. Urban areas may experience heightened danger due to the 'urban heat island' effect, which traps heat and keeps nighttime temperatures elevated. Medical professionals caution that even brief exposure to such extreme conditions can lead to heat exhaustion, heat stroke, and respiratory issues.
