With record-challenging heat building in the city through late week, the fire threat will increase in Southern California this week.
After temperatures reached the high 80s on Wednesday, the city is expected to hit the mid-90s on Thursday. Thursday's forecasted high will give the city the chance to break its old record of 89 degrees set in 1929.
However, the heat combined with the gusty Santa Ana winds will raise the fire danger from Los Angeles down through San Diego this week.
"The combination of very low humidity, heat, sunshine and wind can cause any fire that gets started to spread rapidly through dry brush and potentially into populated areas," Clark said.
On Wednesday afternoon, a fire broke out in Day Canyon in the Etiwanda Preserve, located just north of Rancho Cucamonga near Los Angeles. Residents in the vicinity of the fire were evacuated Wednesday afternoon.
Although mandatory evacuations were lifted Thursday morning, 55 fire engines and 19 fire crews were called in to battle the blaze. As of Thursday morning, the fire had spread to approximately 1,000 acres.
Through Thursday, the Santa Ana winds are expected to gust up to between 40 and 70 mph, continuing the fire threat for the region.
People are strongly urged to use extra caution when operating machinery or equipment that can spark a fire.
