San Leandro firestorm of 2023 (PresidentOfYes12)

The San Leandro firestorm of 2023, more commonly known as the San Leandro firestorm or just the San Leandro fire, was a large, and deadly suburban conflagration that occurred in and around the hillsides of San Leandro, California in October of 2023, and lasted about one week. It originated from a lightning strike and rapidly grew due to winds from a cold front that had passed the day prior, and aided by warm, dry air, quickly grew into a massive firestorm. It killed 19 people, destroyed over 1500 buildings, including 1100 single-family houses, and cost over $1.25 billion in economic losses.

Origins of the fire
A lightning strike hit a grass field near the city of San Leandro, sparking a brush fire. Dry winds fanned the fire quickly, resulting in it spreading out of the grass field it originated from. It had reached a size of around 15 acres when firefighters arrived at the scene and worked to extinguish it.

Initially, the fire had been cut down to a negligible size, resulting in the firefighters mistakenly thinking that it had been extinguished. About 30 minutes later, a much larger fire was reported to have been spreading down a mountain and towards San Leandro, as it was fanned by winds of around 55 mph. It spread out quickly, and overwhelmed firefighters trying to battle the fire.
