An intense, long-duration heat event has begun in the Western United States that may become one of the most extreme September heat waves ever observed in the region. It is already breaking records, prompting appeals for energy conservation, fueling fires and leading to heat-related illnesses.

On Wednesday, record highs for Aug. 31 were set from California to Montana. In Southern California, Burbank and Anaheim established records for the entire month of August as the mercury soared to 112 and 106. That followed record highs of 90 and 100 degrees in Seattle and Portland on Tuesday.
