A major wildfire in Southern California has prompted evacuation orders for thousands of residents as the blaze continues to grow. The Highland Fire, which broke out on Monday in Riverside County, has burned over 2,200 acres and is currently unchecked. Fueled by Santa Ana winds, the fire quickly spread, leading to evacuation orders for approximately 4,000 people. The fire has also destroyed three buildings and damaged six others so far. Firefighters are battling the blaze on the ground while aircraft drop retardant from above. The cause of the fire is under investigation. The evacuation orders remain in effect and several roads have been closed due to the ongoing threat. This wildfire comes as a reminder of the importance of being fire ready, even during cooler weather, according to Cal Fire. Southern California has experienced a mild fire year due to heavy rainfall earlier in the year, but dry conditions and strong winds have increased the risk of wildfires.
