Excessive Heat Warning, Heat Advisory in Effect for San Diego

Extreme heat and high humidity in San Diego County created dangerous conditions for San Diegans on Tuesday, according to the National Weather Service.

An excessive heat warning was issued for the lower deserts, including the Anza-Borrego Desert, from 10 a.m. Tuesday to 8 p.m. Wednesday, the National Weather Service said. 

A less severe heat advisory was issued for inland areas, including Escondido, El Cajon, San Marcos, La Mesa, Santee, Poway, Santa Ana, Anaheim, Garden Grove, Orange, Fullerton, and Mission Viejo.

An excessive heat warning or heat advisory is issued when there is a risk for heat illness. The NWS advises people to drink plenty of fluids, stay in an air-conditioned room and out of the sun. 

The NWS said daily heat records for June 11 were broken in at least three communities. 

Campo's high of 102 beat its previous record set in 1979 by two degrees. Thermal reached 116 degrees, beating its previous record of 112 and setting a daily heat record for the second straight day.

Thermometers in Borrego reached 115, three degrees up from its 1985, and in El Cajon, the 91-degree high tied its record set in 1995.

By 12:30 p.m., the hottest temperature recorded was 98 degrees in Campo, according to the NWS. Ramona and El Cajon were close behind with 97 and 91 degrees respectively. 

Mountain regions saw triple-digit heat and Ocotillo Wells and Borrego saw highs above 110.

An NBC 7 crew canvassed an area between the shoreline and Lakeside to see how San Diegans were beating the heat.

At La Jolla Shores, thermometers read a pleasant 87 degrees.

"Good winds, nice and cool, the water's prety great. Solid day for the beach," one happy beachgoer said.

At the library in University City temperaturs stopped just short of 90 degrees, and down State Route 52 and into Tierrasanta, NBC 7 found school children frolicking in the 90-degree heat.

"It's so hot!" one child exclaimed.

"I've been sweating at recess! I want to get out of school now because it's so hot!" screamed another.

Over in Santee, you guessed it, it was even hotter -- 107 degrees at the trolley stop. But where there's a will there's a way, and in this case that way was ice cream.

The hottest reading our crew found Tuesday was 109 degrees at the Lakeside rodeo park. That heat didn't stop a squad of El Capitan High School football players were gearing up for a summertime game. They told NBC 7 they've been staying hydrated.

Fire crews were sent to the area near Avenida Cuatro Vientos, north of San Dieguito Road, in the area west of Interstate 15, north of State Route 56 and east of Interstate 5 for a vegetation fire that sparked at around 2 p.m.

As of around 4 p.m., it was stopped at 3 acres and was 50 percent contianed, according to Cal Fire.

The potentially dangerous heat was expected to continue until Wednesday. A big cool down is expected during the latter half of the week, Parveen said. 

On Monday, record highs for June 10 were broken in at least four communities, according to the NWS.
