A statewide Flex Alert will go into effect Tuesday as temperatures soar into the triple digits for some parts of Southern California after a weekend that brought record heat and damaging storms to inland areas.
Tuesday's Flex Alert will be the second issued during a stretch of record breaking heat that continued to blanket the region Monday. There is no Flex Alert in effect for Monday, but the Independent System Operator -- the main agency that operates the state's power grid -- urged consumers to conserve power, especially between 11 a.m. and 6 p.m.
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.
The extreme heat prompted the City of Los Angeles to extend hours at its cooling centers until 9 p.m. Monday and Tuesday.
A large part of Southern California remain under an excessive heat warning Monday, when the temperature is expected to reach 103 degrees in Ontario. An excessive heat warning indicates health-threatening conditions resulting from high air temperatures and humidity levels.
"If you've been counting, we have seven days in a row where we've seen record breaking temperatures in Ontario," said NBC4 forecaster Elita Loresca. "We will see a little bit of cooling by the middle of the week."
With triple-digit temperatures, one would think pools around Southern California -- like the one at the Calabasas Swim and Tennis Center -- would be packed. But it wasn’t.
"People have been flocking to the pool just to try to stay cool, but we’ve noticed some of our numbers go down too," the club’s recreation coordinator Raine Kishimoto said. "It seems like if you’ve made it to the pool you’re good to go. If not, people are not leaving their houses. They are staying in their air conditioning or in the mall."
The heat didn’t stop members from playing tennis, though, albeit with a few modifications.
"A lot of water breaks," said Jonas Wallgard, tennis director. "We have kind of games with water guns and cooling them down with ice and having water wars down there in between and then we go out and play some tennis."
The excessive heat warning will be in effect from 11 a.m. to 8 p.m. in the San Gabriel, San Fernando, and Santa Clarita valleys, the L.A. County portion of both the San Gabriel and Santa Monica mountains, and several areas of Ventura and Santa Barbara counties.
