California firefighters make headway on blazes with help from cooler weather
Marine layer floating over region calmed fires, with LNU Lightning Complex 33% contained as 140,000 affected by evacuation orders
Aided by cooler weather and reinforcements, firefighters in California made headway on Wednesday in containing the three giant blazes burning across the Bay Area.
The fires, which were sparked last week by an unusual bout of lightning and stoked by an extended heatwave that desiccated fire-fueling vegetation, were calmed in part by a marine layer – a layer of cool, humid air from the ocean – floating over the region.
