YREKA (California), Aug 3 — Search teams have found two more bodies in an area scorched by a forest fire raging for a fifth day in northern California near the Oregon border, bringing to four the number of lives lost in the state’s biggest blaze this year, officials said yesterday.

The latest two victims were found on Monday at separate homes along a highway that runs through the fire zone in the Klamath National Forest about 300 miles (483 km) north of San Francisco, according to a statement issued by the Siskiyou County Sheriff’s Office.

The remains of two other people, who were apparently trying to escape the fire at the last minute, were discovered on Sunday inside a burned-out car that ran off the driveway of another home along the same highway, sheriff’s officials said on Monday.

Authorities said no further information would be released on any of the deaths until positive identification is made and the next of kin have been notified.

As of yesterday, the so-called McKinney fire had charred more than 56,000 acres (22,662 hectares) of drought-stressed timber, tall grass and brush.

Some 2,000 residents have been ordered evacuated since the blaze erupted on Friday.

Numerous homes have been destroyed and nearly 5,000 dwellings were listed as threatened by flames, but authorities have yet to quantify the extent of property losses.

The doubling of the death toll came after a night of relatively mild fire growth compared with previous nights. High humidity levels helped tamp down the flames while crews made progress carving buffer lines to protect communities on the edge of the fire zone, Dennis Burns, a fire behaviour analyst for the incident management team, told a morning briefing.

Much of the effort was focused on the outskirts of Yreka, the Siskiyou County seat and former gold mining town now home to 7,800 residents.

Burns said thunderstorms in the forecast may bring welcome rainfall to the area, or erratic winds that could fan the flames anew, as well as possible lightning strikes that might ignite further fires.

The cause of the McKinney blaze was under investigation.

The fire erupted amid record-breaking heat in a region where drought-desiccated trees and undergrowth had already created a highly combustible fuel bed, in keeping with extreme conditions scientists ascribe to human-induced climate change. — Reuters
