Multiple heat advisories were issued by the National Weather Service for Sunday and Monday, when temperatures in parts of Southern California are expected to reach the high 90s and into the 100s.
An advisory for the Inland Empire, covering valleys in Riverside and San Bernardino counties, was issued for 10 a.m. Sunday to 8 p.m. Monday with temperatures predicted to peak Monday around 100-105 degrees.
The NWS recommends that residents avoid consuming alcohol or caffeine and drink extra water, check in on elderly family and neighbors, monitor children and pets closely and avoid strenuous activity.
Hikers were urged by the Cleveland National Forest to take safety precautions including hiking early in the morning, bringing plenty of water and to hydrate often.

In inland Orange County, highs were expected to linger in the upper 80s and lower 90s for the next few days.
The hot and dry conditions also create an elevated fire risk.
“As the high pressure centers over the Great Basin, this opens the door for easterly monsoonal flow to enter Southern California,” the NWS said. “Slight chances of thunderstorms (are) in the forecast for the mountains and deserts on Monday afternoon and evening.”
A cooling trend is expected later in the week and into the holiday weekend.
The high temperatures expected Sunday, according to the NWS:
- Downtown LA: 87
- Fullerton: 92
- Long Beach: 79
- Mission Viejo: 91
- Redlands: 102
- Riverside: 102
- San Bernardino: 103
- Torrance: 78
- Van Nuys: 98
- Whittier: 90
