Archived official description
...RISK FOR RAPID FIRE GROWTH AND EXTREME FIRE BEHAVIOR CONTINUES WITH ANY NEW FIRE STARTS TODAY, ESPECIALLY IN TARGETED RED FLAG WARNING AREAS... Offshore winds are not as strong or widespread as the past couple of days, but will still create a risk for new fires to have rapid growth in wind prone areas of LA/Ventura counties, as very warm and dry conditions persist. While many areas have been cancelled in the Red Flag Warning area, a few targeted Red Flag Warnings persist where offshore winds are expected to remain strongest through this afternoon. * AFFECTED AREA...Santa Clarita Valley, Santa Susana Mountains and Western San Gabriel Mountains and Highway 14 Corridor. * TIMING...Until 6 PM PDT this evening. * WINDS...Northeast to east 15 to 25 mph with gusts of 25 to 40 mph, gradually diminishing later this afternoon into evening. * RELATIVE HUMIDITY...Minimums of 10 to 20 percent common. * IMPACTS...If fire ignition occurs, conditions are favorable for extreme fire behavior which would threaten life and property.
Instructions in this archived message
A Red Flag Warning means that critical fire weather conditions are either occurring now, or will shortly. Use extreme caution with anything that can spark a wildfire. Residents near wildland interfaces should be prepared to evacuate if a wildfire breaks out. See readyforwildfire.org and wildfirerisk.org for information.
