This will be a PARTICULARLY DANGEROUS SITUATION (PDS) Red Flag Warning event in many areas, with the combination of strong upper level wind support, tightening offshore pressure gradients (LAX-Daggett peaking at -7 to -8 mb), and moderate cold air advection. The strongest winds with this Santa Ana wind event are expected to be Wednesday morning into Wednesday night when widespread damaging wind gusts of 60 to 80 mph are likely in the mountains and foothills of Los Angeles and Ventura Counties (including the Santa Monicas and Santa Susanas), with isolated gusts of 80 to 100 mph possible in favored areas of the San Gabriels. Similar winds are expected once again in the mountains Thursday night. For wind prone coastal and valley areas of Los Angeles and Ventura counties, damaging gusts of 50 to 70 mph will be likely (including the Malibu Coast and Ventura County coastal plain). Due to the strong upper level wind support, typical wind sheltered areas such as portions of the LA basin all the way to the coast, Lake Casitas and Ojai, as well as the Channel Islands and Catalina Island are expected to see gusty north to northeast winds with associated Red Flag conditions. Humidity levels are also expected to lower to between 8 to 15 percent by Wednesday afternoon with these low humidities likely to linger into Thursday and Friday. These are Extremely Critical and highly volatile conditions. Any new fires in the Red Flag Warning area -- and especially the PDS Red Flag Warning area -- will have rapid fire spread, extreme fire behavior, and long range spotting.

Strongest winds expected along the Highway 118/210 corridors in eastern Ventura county valleys to western San Fernando valley, with highest risk for Simi Valley, Moorpark, Porter Ranch, and San Fernando. Offshore winds are expected to be 5 to 10 mph weaker on Thursday. * RELATIVE HUMIDITY...Humidity levels will likely fall to between 8 and 15 percent by Wednesday afternoon, and linger into Thursday. * IMPACTS...If fire ignition occurs, conditions are favorable for rapid fire spread and extreme fire behavior which would threaten life and property. With the threat of even stronger Santa Ana winds and drier fuels with the Wednesday/Thursday Santa Ana event, there will be an increased risk for long range spotting. PRECAUTIONARY/PREPAREDNESS ACTIONS... 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.
