We've seen reports about Los Angeles County being under "fire weather watch" and "red flag warning." What is the difference?

Red flag criteria is generally when relative humidity is at 15% or less, combined with sustained winds and/or gusts of 25 mph or greater. Both of these conditions must occur simultaneously for at least 3 hours in a 12 hour period, according to the NWS.

The fierce winds in the Los Angeles area subsided Friday, but critical fire weather conditions remain and red flag warnings are still in place.
