Red Flag Warnings in northern and southern California include forecasts for very strong winds and single digit humidity that will make wildfires difficult or impossible to suppress until, 1) the weather changes, or 2) the fire runs out of fuel.

Conditions in the southern part of the state will be critical, especially in the greater Los Angeles area which should expect 30 to 55 mph winds gusting at 75 to 85 with humidity of 3 to 8 percent.

Below is the National Weather Service forecast for Santa Clarita, near last week’s Tick Fire north of Los Angeles: Tuesday night, winds 41 to 46 mph gusting out of the northeast at 61 to 68. The relative humidity will drop to the single digits by noon on Wednesday.
