High temperatures raise fire risk while poor air quality prevents residents from going outdoors amid Covid-19Record-high temperatures are expected across California for the holiday weekend, increasing fire risk and exacerbating poor air quality for residents yearning to go outside because of the pandemic but forced indoors because of smoke from nearby fires.As fires continue to burn throughout the state, the National Weather Service (NWS) declared excessive heat watches in the San Francisco Bay Area and Sacramento starting on Saturday and lasting until Monday. In Los Angeles, where temperatures of 100F to 115F were expected away from the beaches, dangerous heat was declared.“This is an exceptionally dangerous event, especially considering the holiday weekend and the ongoing pandemic,” warned the NWS forecast office in San Diego. “This event will be hotter than the recent mid-August heat wave.
