Record-setting heat and intense wildfires marked Labor Day weekend across California, sending people flocking to the beaches, while also prompting a dramatic air rescue involving hundreds of people.Along with the wildfires that have now burned more state acreage than any other year on record, according to the National Interagency Fire Center, a holiday weekend full of record-breaking temperatures has Golden State residents hoping for cooler days.The toasty temperatures largely baked the southwestern portion of the state as multiple towns and cities recorded temperature readings of at least 115 degrees Fahrenheit. At Pierce College in Woodland Hills, a reading of 121 F on Sunday set a new high temperature record for Los Angeles County. The 121 F day set not only a daily record but also an all-time record for the densely populated county. The previous all-time high came in 2006 during July.According to AccuWeather Meteorologist Randy Adkins, sweaty Southern Californians can blame a historically unique shift in the jet stream for the recent conditions."This is related to an unusually strong amplification of the jet stream, creating a historically strong upper-level ridge over the West with the jet stream shifted well to the north into Canada," Adkins said. "This ridge set up in essentially the ideal spot, southern Nevada, for creating such intense heat across Southern California on Sunday."

The Los Angeles Sheriff's Department search and rescue team was called to the aid of a woman who had started hiking in the morning but suffered a seizure and died as responders were unable to resuscitate her. The official cause of her death is pending, but Los Angeles County Sheriff's Deputy Morgan Arteaga told CNN that the death was likely heat-related.Some beach parking lots were reportedly closed in Los Angeles, Orange and San Diego counties due to capacity being reached, The Associated Press reported. "Very busy conditions. The beaches are packed wall to wall," Orange County Lifeguards Capt. Brad Herzog said, according to The AP.On top of the intense heat, Adkins said conditions have remained particularly dry, which has done no favors to the overwhelmed firefighting crews."Not only does that bring a very dry atmosphere into the region, but it promotes what is known as subsidence, a broad area of sinking air," he explained. "The air compresses as it sinks, leading to increase warming and thus maximizing temperatures at the surface. Additionally, the surface flow was offshore, preventing the marine layer from moving inland Saturday night, so there was a high launching pad for temps to soar from on Sunday."

But this season has been unlike any other.Both the LNU and SCU Complex fires continue burning in the central regions of the state, totaling nearly 775,000 acres between the two fire systems, both of which were ignited by lightning.More than 200 residents were airlifted to safety in the state's Sierra National Forest as a fast-moving blaze known as Creek Fire ignited. As the fire erupted late Saturday, officials told visitors at the Mammoth Pool Reservoir about 90 miles northeast of Fresno to shelter and blaze and jump in the water if necessary as the fire grew late Saturday.Military helicopters were used to rescue those trapped by the flames and transfer them to hospitals in Fresno.The Fresno Fire Department stated that out of 63 people who had been rescued on Saturday night, 12 patients suffered severe to moderate injuries. The remaining 51 patients had minor or no injuries.

Also during the weekend, a separate fire ignited in San Bernardino County when a pyrotechnic device used at a gender reveal party ignited in El Dorado Ranch Park in Yucaipa, according to Cal Fire. As of Monday afternoon, the fire, now dubbed the El Dorado Fire, has grown to nearly 7,400 acres acres and is 7% contained.Gusty winds from what forecasters are calling an "unusually strong" wind event may worsen wildfire conditions as the week continues.According to Adkins, cooler conditions may be en route for the stifled areas, but how much cooler and much help they will provide remains unknown."As far as things moving forward, the ridge will weaken Monday through midweek and shift offshore as the disturbance digs southward across the Rockies," he said. "With this change, temperatures will trend downward, but they will still be 5-10 degrees above average Tuesday through the end of the week and into next weekend."Keep checking back on AccuWeather.com and stay tuned to the AccuWeather Network on DirecTV, Frontier and Verizon Fios.
