SAN BERNARDINO • County Health Officer Dr. Maxwell Ohikhuare issued an extreme heat advisory for San Bernardino County on Monday evening, according to a press release.
Victorville residents spent their Monday in 106 degree weather, according to AccuWeather. Daily Press weather spotters reported 103 in Phelan, 101 in Apple Valley and 99 in Hesperia.
High temperatures are forecasted for the inland and desert regions.
The National Weather Service said a warming brought by a strong, upper-level high centered over the Great Basin would peak on today and Wednesday. Excessive heat warnings will be in effect most of Tuesday across the deserts, the NWS said.
AccuWeather forecasts 101 Tuesday and Wednesday for Hesperia, as well as 98 on Thursday.
Residents are urged to take precautions that will prevent heat-related illness.
Extremely high or unusually hot temperatures can affect your health. Most vulnerable are the elderly, those who work or exercise outdoors, infants and children, the homeless or poor, and people with a chronic medical condition.
Forecasters also warned that the heat, combined with low humidity levels, will elevate the fire danger. Firefighters jumped on several small fires Monday in San Bernardino, San Diego and Los Angeles counties.
Dry lightning will add to fire worries as a flow of monsoonal moisture arrives from the southeast later in the week, affecting Southern California and the southern Sierra Nevada, the NWS said.
