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.
Below is information about this weather event from Jim Cantore of The Weather Channel Tuesday morning:
No good news for California over the next 48 hours. Current fires and any new fires will be almost impossible to control at the height of pending high wind/ super low RH event. Some scary scenarios come to mind with the latest SPC read. pic.twitter.com/m9GDKrJLxT

The three large utility companies could potentially shut off the power to millions of people in California beginning Tuesday. The maps below were collected from the web sites of the power companies at 8:30 a.m. PDT October 29 and show areas that could potentially be affected by power shutoffs. The information could change.
(Red Flag Warnings can be modified throughout the day as NWS offices around the country update and revise their weather forecasts.)
