Overview
- The Little Fire began in the Sunol area near Vallecitos and Little Valley roads and grew rapidly on Tuesday from single‑digit acreage to just over 1,000 acres within hours.
- A large, unified response of engines, hand crews, bulldozers, helicopters and multiple air tankers stopped the blaze’s forward progress overnight and raised containment to about 40% by Wednesday morning.
- Mandatory evacuation orders were issued for multiple zones including Ruby Hill and PLS‑081 and PLS‑103, and many orders were later lifted or downgraded while some remain in effect.
- One firefighter suffered minor injuries when a fire engine rolled over, was treated at a hospital and has been released, and officials say no structures have been reported lost so far.
- Hot, dry weather and gusty winds fueled rapid spread, smoke prompted East Bay air‑quality advisories, and investigators have not yet determined the fire’s cause.
