Brace Yourself for More Triple-Digit Heat

Stay hydrated and avoid strenuous activity advises the National Weather Service.

Temperatures again will climb into triple-digit territory in valley areas of the Southland today.

"The hot temperatures combined with very low humidities will bring elevated fire weather concerns to the interior portions of southwest California" much of this week, the National Weather Service (NWS) said in an advisory, blaming the heat wave on a strong upper-level high pressure system centered over the Great Basin.

Temperatures are expected to range between 102 and 110 in the Antelope Valley and between 92-107 in the Santa Clarita and San Fernando valleys as well as mountain areas at low elevations, according to an NWS advisory.

Anyone planning to spend time outdoors this week should stay hydrated and avoid strenuous activity, according to the weather service.
