LOS ANGELES — Californians will swelter through another day of scorching heat Tuesday before things start to cool down.

The National Weather Service says many places could see triple-digit temperatures, including the Central California valleys.

Santa Rosa is expected to reach 91.

Red flag warnings are up until evening in the Central and Southern California mountains and valleys because of hot, dry weather and winds that could gust up to 30 mph.

The Los Angeles area will have highs in the 90s, with San Francisco and San Diego in the mid-80s.

However, an increasing onshore flow should cool things down a few degrees compared to Monday and strengthen through the week.

El Cajon broke a daily heat record Monday with a high of 103. A high of 100 at Santa Maria Airport, Lancaster's 99 and Kentfield's 97 also broke records.
