La Jolla High School is among about 120 San Diego Unified School District schools operating on a “minimum-day schedule” as triple-digit heat is set to grip the San Diego area on Tuesday, Sept. 16. After-school activities were canceled at all city schools.
A National Weather Service heat advisory for the area valleys was in effect until 7 p.m. as high pressure and weak onshore flows continue to generate heat in the region. Forecasters said highs would be in the 80s along the coast, in the 90s a few miles inland and more than 100 degrees in the inland valleys.
A five- to eight-degree cool-down is expected to bring some relief to the area beginning Wednesday, Sept. 17 -- but monsoonal effects from nearby Hurricane Odile wil lbring an increase in humidity, making things uncomfortable, if in a different way.
The heat wave also prompted San Diego Gas & Electric to ask its customers to lessen the strain on the electric grid by reducing their energy consumption between 11 a.m. and 6 p.m. SDG&E customers who participate in the “Reduce Your Use” program could receive a bill credit for doing so, according to the utility.
