Devastating Caldor Fire continues to burn toward Lake Tahoe, forcing thousands to evacuate

A trough, or a dip in the jet stream, is moving through the region and bringing gusty winds from the southwest and very dry air. A red flag warning for critical fire weather is in effect until 11 p.m. Wednesday, with the strongest gusts expected Tuesday afternoon and evening, particularly at higher elevations, where the Caldor Fire is burning.
