It’s Another Triple Digit Day: Pasadena, Southland Continue to Swelter Under Record Heat

No relief was expected from the heat until Friday, according to the National Weather Service.

Temperatures are expected to reach 102 degrees again on Thursday and 100 on Friday before dipping into the high 90s on Saturday and remaining there for the rest of the weekend.

“Extreme heat will significantly increase the potential for heat-related illnesses, particularly for those working or participating in outdoor activities,” according to the weather service. “Take extra precautions if you work or spend time outside. When possible, reschedule strenuous activities to early morning or evening.

“Very hot conditions will continue through the week with very warm nights, especially for valley and interior areas,” according to NWS. “Temperatures will cool only slightly later in the week and will remain above normal through early next week.

An excessive heat warning was in effect until 9 p.m. Thursday in the San Gabriel Valley and Mountains.

Forecasters warned that excessive heat and a heightened risk of wildfires would last at least through Thursday.

Rolling blackouts were again averted Tuesday thanks to conservation by consumers, imported energy, and power from wind plants, according to the California Independent System Operator (ISO), which manages the state’s power grid.

Residents were being asked to use air conditioning early in the day and set thermostats no lower than 78 in the afternoon and evening hours, while avoiding the use of major appliances during the Flex Alert hours.
