Cal Fire said that firefighters were being challenged by limited access and hot weather, and were attacking the fire on the ground with engines, crews, and bulldozers, and in the air with tankers and helicopters. The agency said it was a unified command with Alameda County Fire Department.

The Oakland Fire Department said it was providing a mutual aid response with about 25 firefighters headed to Pleasanton as of 5:30 p.m.

Smoke from the Little Fire was expected to impact air quality in the East Bay, the Bay Area Air District said. The district urged residents in affected areas to stay alert to news coverage and health warnings related to smoke. Pollution levels were not expected to exceed the national 24-hour health standard and a Spare the Air alert was not in effect.
