Strong weekend winds set to hamper bid to fight California’s largest wildfire

Colder temperatures and rain expected in Mosquito fire locale but winds could throw burning embers and create spot fires

Strong winds and rain expected over the weekend could hamper the efforts of California firefighters to battle a week-old wildfire that has become the largest in the state so far this year.

The weather system is forecasted to bring colder temperatures and precipitation - from a quarter of an inch (0.63cm) to more than 1in (2.54cm) of rainfall over several days - to the Mosquito fire, which is raging about 110 miles (177km) north-east of San Francisco.
