Relief from triple-digit heat expected by mid-week for most areas
A heat wave that brought record-breaking temperatures to Southern California was expected to subside — gradually — bringing near-average temperatures to many locations by mid-week, the National Weather Service said Sunday, July 8.

But in the meantime, triple-digit temperatures will continue Sunday through Tuesday for several valleys and Inland areas, with possible summer monsoon showers forecast Sunday for Southern California mountains, the San Gabriel Valley, and Inland valleys for Sunday evening.
Just before 3 p.m. Sunday the National Weather Service issued an urban and small-stream flood advisory for Riverside County. Locations that could expect flooding included southeastern Palm Springs, eastern Anza, Palm Desert, Highway 74 between Mountain Center and Anza, and the Santa Rosa Mountains.
The advisory was set to end at 5:45 p.m. Sunday.

Several wild fires and brush fires broke out throughout the region during the record-breaking heat. High-intensity rainstorms hit the mountains and several Inland valleys Saturday. In the Riverside County city of Banning, one system toppled utility polls and trees, including in Sylvan Park, residents said.
Highs for Sunday were forecast mostly in the low 100’s for interior areas, but up to 106 for Riverside and San Bernardino counties. Beaches in Los Angeles and Orange will do better, generally reaching the low-to-mid-80s Sunday.
The break in the heat for most areas takes place Wednesday, with relatively cooler temperatures in the mid-80s to low 90s for most interior regions — Inland temperatures will be slightly higher — and continued cooling at the beaches.
