Temperatures began rising this weekend as another heat wave settled into Southern California, with conditions becoming potentially dangerous on Sunday into Monday in some areas, and warm conditions lingering into next week.
“High pressure will build into the region through the weekend and bring a warming trend through at least Sunday,” according to the National Weather Service. “Triple-digit high temperatures will be common over the hottest valleys, foothills and desert between Saturday and Monday. Very warm conditions are likely to continue Tuesday through Thursday with increased clouds and possible monsoonal showers and thunderstorms.”

“Extreme heat will significantly increase the potential for heat-related illnesses, particularly for those working or participating in outdoor activities,” according to the NWS.
A less-severe heat advisory will be in effect in the Santa Clarita Valley and San Fernando Valley from 10 a.m. Sunday to 9 p.m. Monday, with temperatures potentially topping 103.
