SAN FRANCISCO (Reuters) - Fire crews battling to keep a massive blaze from invading the heart of California's Yosemite National Park seized on cooler weather and lighter winds on Thursday to slow the spread of flames ahead of a holiday weekend marking the end of the peak summer tourist season.
Progress came after a long stretch of Yosemite's main east-west road was closed on Wednesday through the western half of the park as crews tightened their grip on the blaze, extending containment lines around 30 percent of the fire's perimeter by the end of its 12th day.
