California firefighters are battling extreme weather conditions as they work tirelessly to contain the Corral Fire, which has engulfed more than 12,500 acres outside the town of Tracy. The blaze, which started on Saturday near the Lawrence Livermore National Laboratory Site, has prompted mandatory evacuation orders for residents in several areas.

Dry grass and gusty winds have contributed to the rapid expansion of the Corral Fire, with the flames quickly spreading to over 10,000 acres by Saturday afternoon. As of Sunday, fire crews had managed to contain only 15% of the fire's perimeter, leaving a substantial area still at risk.

Authorities have issued evacuation orders for areas west of the California Aqueduct, south of Corral Hollow Creek Road to Alameda County, and southward to Stanislaus County. The San Joaquin County Office of Emergency Services has set up a temporary shelter at the Larch Clover Community Center on West Larch Road for affected residents.

The cause of the Corral Fire is currently under investigation. As firefighters battle the blaze, the Lawrence Livermore National Laboratory has reassured the public that the fire does not pose a threat to the science and technology facility.

The situation is further complicated by the impending heatwave in the region. Central California experienced warm temperatures over the weekend, with temperatures reaching the lower 80s. However, starting Monday, the heat is expected to intensify, with Tracy forecasted to surpass 100 degrees on Tuesday.

The National Weather Service has issued an Excessive Heat Watch for millions of California residents, including those in San Joaquin County. The watch will take effect on Tuesday, accompanied by dangerously hot conditions ranging from 95 to 108 degrees. A widespread "major" HeatRisk has been forecasted, adding to the existing challenges faced by firefighters.

In addition to the scorching heat, strong winds are also posing a significant risk to containment efforts. Starting on Monday, gusts between 20 and 30 mph are expected, which could further fuel the fire's growth and make it even more challenging for firefighters to gain control.

As the Corral Fire continues to threaten Tracy and its surroundings, authorities are urging residents to stay vigilant, heed evacuation orders, and prioritize their safety. Firefighters are working tirelessly to combat the blaze and protect affected communities as they battle against soaring temperatures and treacherous winds.
