In light of the Red Flag Warnings, the diminished number of firefighters even before the partial shutdown is something to keep an eye on. According to Leo Kay, the Director of Communication for the U.S. Forest Service, “80 to 90 percent of the agency’s firefighting resources are available” in the wake of the decision by the dysfunctional Congress to shut down much of the government. We asked if those resources are currently working, as opposed to being furloughed but on 2-hour call like some National Park Service firefighters, and he said yes, explaining that they are “excepted employees” during the shutdown.

Firefighters that are still working are telling us that they are not being paid and there is no way to accurately predict WHEN they will receive a pay check.

The Red Flag Warning for the San Bernardino area of southern California predicts a “moderate strength” Santa Ana wind for late Thursday night through Sunday, with northeast to east winds sustained at 25 to 40 mph with local gusts as high as 65 mph through and below canyons and passes. The winds will peak Friday night and Saturday.
