...RED FLAG WARNING IN EFFECT THROUGH THURSDAY 8 PM PST FOR MOST OF LOS ANGELES AND VENTURA COUNTIES FOR EXTREMELY LOW RELATIVE HUMIDITY AND PERIODS OF GUSTY OFFSHORE WINDS... .The Particularly Dangerous Situation (PDS) Red Flag Warning has ended, but dangerous fire weather conditions will persist through Thursday or Friday. Northeast winds will weaken and shrink in coverage tonight into Wednesday, but will remain locally gusty in the favored hills and mountains.

Meanwhile, extremely low humidities will persist with minimums under 10 percent over much of the area and poor overnight recoveries.

As result, the Red Flag Warning has been extended over most of Los Angeles and Ventura Counties through 8pm Thursday. Some of the windiest areas may need to be extended into Friday as well.

* IMPACTS...If fire ignition occurs, conditions are favorable for extreme fire behavior and rapid fire growth, which would threaten life and property.
