SAN FRANCISCO (AP) — Unsettled weather, including possible lightning strikes, may add fuel to an already stubborn wildfire threatening homes in a parched area of Northern California, officials said Sunday.

Crews battling the lightning-sparked blaze burning in steep, rugged terrain near Laytonville in Mendocino County braced for another round of dry lightning and wind, California Department of Forestry and Fire Protection spokeswoman Lynne Tolmachoff said.
