Dubbed the Sycamore Fire, the blaze began before 3 p.m. in Rialto north of the Rancho Verde Golf Course (map), the county Fire Department stated on Twitter.

Winds drove the fire’s spread, but the blaze was held to 3 acres thanks to a “quick response” from multiple agencies, the Fire Department tweeted. Initially, the fire was estimated at 5 acres.

Firefighters and hand crews remained on scene to complete mop-up operations just before 5 p.m.

The fire burned in an undeveloped, brush-filled area north of the Rialto and south of the Cajon Pass, aerial video showed.

County firefighters were working with Cal Fire and the Rialto and San Bernardino city fire departments.

At least one helicopter could be seen dropping water on the blaze at about 4 p.m., aerial video showed.

The blaze came after fires burned about 20,000 acres in San Diego County last week amid Santa Ana wind gusts and high temperatures.

A cooling trend was expected in the Inland Empire this week, with a deepening marine layer that could produce a few light rain showers along and west of the mountains late Monday into Wednesday morning, according to the National Weather Service.
