Santa Ana winds will hit the Los Angeles area yet again this week, bringing extreme risk of rapid fire spread as the region continues to tamp out deadly wildfires that ignited under similar conditions earlier this month.

Two major fires are still uncontained in the Los Angeles area with red flag warnings issued for Monday, meaning powerful Santa Ana winds will make conditions hard for crews to fight already devastating blazes.

Another round of fire weather is expected to last for much of this week as residents return home to the Palisades and Altadena neighborhoods to inspect the devastation.

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.

As firefighters struggle to gain control of massive and deadly wildfires that are raging across parts of the Los Angeles area, the region is once again bracing for the potential of new fires and for current ones to intensify as a new storm system heads for the state.
