As the destructive wildfires continue to burn in Los Angeles County, weather officials have issued a new series of red flag warnings with another round of Santa Ana winds once again expected to slam the region.

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

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.
