A powerful heat dome has settled over much of the Southwest, bringing near-record high temperatures from the San Diego coast to the region’s deserts. Meteorologist Dave Mion with the National Weather Service in San Diego warns that these could be the hottest temperatures of the year, with inland areas reaching dangerous levels.
Impact on the Region Desert regions could see temperatures soar to around 115°F, while San Diego’s inland valleys may approach 110°F. Even coastal areas, typically cooler, are expected to reach the 90s. Ramona, along with much of San Diego’s west-central area, is bracing for extreme heat, with temperatures projected to be 10-20 degrees above seasonal norms. The heat wave is affecting Southern and Central California, extending into Las Vegas and Arizona.
Warnings Issued An excessive heat warning is in effect through late Friday for most of San Diego County, and state power managers have issued a heat bulletin, alerting energy providers of the potential strain on resources. Flex alerts may be issued as energy demand spikes due to air conditioning usage.
Relief in Sight Forecasters predict a return to more typical temperatures starting Sunday, but until then, residents are urged to stay cool, stay hydrated, and limit outdoor activities during peak heat hours.
