Prolonged exposure to high temperatures increases the risk of getting a heat-related illness.
More records are expected to be broken today as temperatures will top out between 106 and 110 degrees in the valley.
An excessive heat warning goes into effect Sunday morning as temperatures continue to rise across the Southland, creating an "elevated fire danger" that will extend into next week, according to forecasters.
The weather service attributed the heat wave to a "strong upper-level high-pressure system over the region combined with weakening onshore flow". A few records were set for the day Saturday, and the NWS said it appears Paso Robles set a new record for the day Sunday at 108 degrees. The first triple digit temperatures are forecast for Tuesday when the high in some areas will exceed 100 degrees.
Dangerously hot weather is expected in the majority of the Bay Area.
Temperatures are expected to climb even further as the week progresses, with highs of over 100 predicted for some inland areas.
"Persons working outdoors or those without access to adequate air conditioning will be more likely to experience heat related illness, such as heat exhaustion", the NWS said of those in areas under the extreme heat warning. A high rip current risk is in effect at beaches on the Los Angeles county coast from now through Tuesday, August 29th.
The National Weather Service warns beachgoers to beware.
