The National Weather Service (NWS) has issued three Excessive Heat Warnings for southern California, and residents impacted should take the necessary precautions. Starting on Wednesday and ending on Friday evening, the NWS is warning that temperatures in Barstow and the Morongon Basin could reach 109ºF, while in Death Valley, they could hit 120ºF.
In the Western San Fernando Valley, the NWS’ warnings read that temperatures could reach anywhere between 105ºF and 113ºF and remain in effect until 8 pm on Friday. However, at night temperatures will fall to the mid-70s which will provide some relief.
Lastly, in the Coachella Valley, San Diego county deserts, and Palm Springs, the NWS forecasts temperatures to reach anywhere between 112ºF and 118ºF. Unlike in the San Fernando Valley, temperatures will not drop dramatically at night, meaning that air conditioning units may need to be kept on.
What precautions should be taken?
For all people, heat places stress on the body, and for children, the elderly, and those with health issues, it can pose an even greater risk. Heat exhaustion or heat stroke can occur when one is exposed and does not, or is unable to, take precautions to help their body stay cool. The NWS advises those affected to drink plenty of water throughout the day, stay inside (ideally in a room with AC), and avoid the sun, if possible. Errands and exercise should be completed during the morning or evening, outside of the peak hours of heat.
