LAFD personnel responded to the Hollywood sign where several hikers suffered mild heat exhaustion

Firefighter-paramedics responded to a hiking trail near the Hollywood sign Tuesday after several hikers reported heat-related exhaustion as some parts of Southern California continued to swelter in triple-digit temperatures.

LAFD units responded to the location on Mount Lee Drive at about 1:30 p.m. after a group of teen hikers reported feeling ill. Firefighters provided water for members of the group and about 10 people were evaluated for mild-to-moderate heat exhaustion on a day when temperatures in the area were in the mid-90s.

Aerial video showed at least one ambulance and two LAFD fire trucks at the location. About 30 LAFD personnel responded to the peak.

"It's still going to be hot and humid today," said NBC4 forecaster Elita Loresca. "There is some nice relief just around the corner. Expect some cooling around the Inland Empire valleys tomorrow."

Warnings remained in effect Tuesday for desert areas in Riverside County, where scattered afternoon and evening thunderstorms are possible.

The forecast includes only a slight drop in temperatures by just two or three degrees in some areas. Inland Empire temperatures will range from the high-90s to near 110 degrees.

Two San Bernardino schools, Arrowhead Elementary  and Cajon High School, will end classes early Tuesday because of the heat.

A statewide Flex Alert is in effect Tuesday. The main agency that operates the state's power grid issues the alerts to urge consumer to conserve electricity.

"The main grid operator for California is tracking nearly 1,000 megawatts in energy reduction by consumers -- an impressive conservation level since it equals the output of two large power plants," Cal ISO said in a news release issued Tuesday.

Conservation tips include setting thermostats at 78 degrees or higher; using fans to cool residences and draw shades over windows; turn off uncessary appliances; and use major appliances during the morning or late evening.
