    "Dangerously hot" temperatures on Monday prompted energy officials to issue a flex alert across Southern California. 

    "We are experiencing this abnormal heat, because we are under a strong dome of high pressure. It is coinciding with the summer solstice, which means the sun is directly overhead. Those two, combined, have made a dangerous recipe for heat," said NBC 7 Meteorologist Jodi Kodesh.

    The hot temperatures caused electricity supplies to tighten in Southern California.

    The state agency that regulates the power supply says SoCal residents should implement "flex alert" procedures. The Independent System Operator called the alert for Monday from 10 a.m. to 9 p.m.

    A flex alert calls for voluntary conservation measures, such as turning off unnecessary lights, postponing use of major appliances and keeping thermostats at 78 degrees and higher.

    By Monday afternoon, a number of heat records had been shattered. El Cajon saw a high temperature of 105, smoking the previous record of 94. Ramona hit 108 degrees, surpassing the former record of 106.

    And Borrego Springs saw a sizzling 118 degrees.

    The National Weather Service (NWS) says an excessive heat watch will be in effect for parts of San Diego County, including valleys, mountains and deserts, from Sunday morning through next Thursday evening.

    Communities that will feel the heat the most include: El Cajon; Santee; La Mesa; Poway; Pine Valley; Julian; Escondido; San Marcos; Lake Arrowhead; Big Bear.

    So how did locals beat the heat? At the El Cajon kickboxing and MMA club Undisputed, workers kept cool by blasting industrial fans.

    "Because we are green conscience, we put some industrial fans behind us, creating a wind tunnel, and it's really been helping with cost savings along with less utilization of electricity," said Stuart Sun of Undisputed Gym.

    By Tuesday, San Diegans may see some relief.

    "The area of high pressure over the southeast will begin to break down Tuesday, but even then, we’ll stay warmer than normal all week," Bledsoe said.

    The warm weather could cause heat-related illness, especially in those partaking in strenuous outdoor activity. If you plan on spending time outside, reschedule activities to early morning or evening and wear loose fitting clothing. Also, drink plenty of water.
