Firefighters try to corral Garnet fire, with parts of California under red flag warning, as Oregon blaze destroys homes

Numerous wildfires across the US west coast are challenging emergency crews from California wine country to central Oregon, as weather forecasters warned that the risks of more blazes sparking is not over yet.

In central California, firefighters are working to corral a fast-growing wildfire that is churning through the Sierra national forest as forecasters warned on Tuesday that lightning strikes from thunderstorms could ignite new fires.

Since breaking out on Sunday afternoon, the Garnet fire has scorched 14 sq miles (36 sq km) of grass, chaparral and timber in a remote area known for camping and hiking about 60 miles (97km) east of Fresno. The fire is currently at 0% containment, and officials said that strong, erratic winds" would likely test firefighters ability to make progress.
