Heat Goes On as Chatsworth Hits Record

A second day of record-breaking temperatures kept the San Fernando Valley sweating Sunday, with Chatsworth setting the pace with a high of 111 degrees, beating a previous record of 108 set in 1991.

The rest of the Valley fared only slightly better, with Van Nuys, Lancaster and Newhall registering a high of 104 degrees. Woodland Hills followed with 102 and Burbank at 101.

And it’s not over yet, although the temperatures should come down a bit, forecasters said.

Triple-digit afternoon temperatures are expected to continue in several areas of the Valley, due to an upper-level high-pressure system, said Scott Breit, a meteorologist with WeatherData Inc., which provides forecast information to The Times.

Chatsworth and Woodland Hills, which are expected to be the warmest spots in the Valley today, could see afternoon highs of 102, Breit said. Slightly cooler temperatures are expected in Burbank and Van Nuys.

Accompanying the heat will be a very high ultraviolet index reading of 10, at noon, when the sun’s rays are most direct, Breit said. Sunscreen is recommended; people with fair skin could begin to burn within five minutes of exposure, he added.

Tuesday, however, will bring a cooling trend that is expected to last through Thursday, Breit said. “There’s a weakening in the upper level high pressure and the marine layer will be a little bit thicker,” he said.

High temperatures will range from the upper 80s to mid-90s in the Valley on Tuesday, Wednesday and Thursday.

Morning lows for those days are expected to be in the low to upper 60s.

Beginning Friday, the upper-level high will begin to strengthen, bringing more hot weather. Friday’s highs are expected to range from the low to upper 90s.
