The worst of a weekend heat wave and smog hit Southern California over the weekend, APA reports citing Xinhua.

The heat peaked Saturday as a high-pressure zone extended from the Southwest and lingered over the region, according to the National Weather Service. Temperatures should start to cool by Monday, when a trough of low pressure is forecast to move into the area.

Officials have issued a heat advisory for most of the Los Angeles County valleys and mountains, as well as the Inland Empire, where triple-digit temperatures are forecast through the weekend, according to local media reports.

The advisory is in effect through Sunday for the Santa Clarita, San Fernando and San Gabriel valleys, with temperatures forecast to hit 34 to 39 degrees Celsius.

Temperatures could reach 40 degrees Celsius across lower elevations in the mountains.

In the San Bernardino and Riverside county valleys, a heat advisory is in effect through Monday. High temperatures there are expected to range from 37 to 41 degrees Celsius.

Air quality officials also issued an ozone advisory for the South Coast Air Basin through Tuesday morning, saying that the heat will combine with atmospheric inversions to trap smog pollution close to the ground.
