Heat, wind double challenges in California fires
SOUTH LAKE TAHOE, Calif. — Spiking temperatures and increasing winds on Sunday added to the challenges faced by firefighters battling blazes across Northern California, including one that continued its march toward the Lake Tahoe resort region.
“It is going to be the hottest day so far since the fire began, and unfortunately, probably the driest,” said Isaac Lake, a spokesman for the two-week-old Caldor Fire.
Flames churned through mountains just a few miles southwest of the Tahoe Basin, where thick smoke sent tourists packing at a time when summer vacations would be in full swing ahead of the Labor Day weekend.
Triple-digit temperatures were possible, and the extreme heat was expected to last several days, Lake said. A red flag warning for critical fire conditions was issued for Monday and Tuesday across the Northern Sierra.
Crews working in rugged terrain scrambled to douse spot fires caused by erratic winds.
“It’s so dry out there that when embers blow out into the unburned fuel beds, the probability of ignition is 90 percent,” Lake said.
The blaze that broke out Aug. 14 was 19 percent contained after burning nearly 245 square miles — an area larger than Chicago. More than 600 structures have been destroyed and at least 18,000 more were under threat.
The Caldor Fire has proved so difficult to fight that fire managers pushed back the projected date for full containment from early this week to Sept. 8. But even that estimate was tenuous.
Meanwhile, California’s Dixie Fire, the second-largest in state history at 1,193 square miles, was 48 percent contained in the SierraCascades region, about 65 miles north of the Caldor Fire. Nearly 700 homes were among almost 1,300 buildings that have been destroyed since the fire began in early July.
More than a dozen large fires are being fought by more than 15,200 firefighters across California. Flames have forced thousands to evacuate this year while blanketing large swaths of the West in unhealthy smoke.
