...HIGH RISK FOR EXTREME FIRE BEHAVIOR WITH ANY NEW FIRE STARTS THURSDAY THROUGH FRIDAY DUE TO MODERATE TO LOCALLY STRONG SANTA ANA WINDS AND LOW RELATIVE HUMIDITY... .Moderate to locally strong Santa Ana winds will quickly develop on Thursday, peak Thursday afternoon through Friday afternoon, then weaken through the weekend. Meanwhile, dry air will settle over the region and dry out any helpful effects of the recent rains. Fire weather watches are now in effect, which will likely be upgraded to Red Flag Warnings by Wednesday. Some areas may see Red Flag conditions linger into Saturday. Interior Santa Barbara and San Luis Obispo Counties may also see Red Flag conditions on Friday, and a Fire Weather Watch is being considered. The National Weather Service in Los Angeles/Oxnard has issued a Fire Weather Watch for wind and low relative humidity, which is in effect from Thursday morning through Friday evening.

* WINDS...Northeast winds 20 to 40 mph with gusts of 50 to 70 mph.

* RELATIVE HUMIDITY...Minimums of 8 to 20 percent common.

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

* WHAT...For the Beach Hazards Statement, dangerous rip currents and elevated surf are expected. For the Coastal Flood Advisory, minor to moderate coastal flooding can be expected near times of high tide.

* WHERE...Malibu Coast and Los Angeles County Beaches.

* WHEN...For the Coastal Flood Advisory, until 2 PM PDT Tuesday. For the Beach Hazards Statement, through Tuesday afternoon.

* IMPACTS...Minor to moderate flooding of sea water is likely around high tide at low-lying beach and harbor areas that is uncommon with normal tidal ranges. Enhanced beach erosion is possible. The risk for significant damage is very low. There is an increased risk of ocean drowning. Rip currents can pull swimmers and surfers out to sea. Waves can wash people off beaches and rocks, and capsize small boats nearshore. Large secondary high tides are also expected each evening.

* ADDITIONAL DETAILS...High tides are expected to peak around 7.1 to 7.3 feet on Tuesday morning. A Beach Hazards Statement may be issued on future shifts to follow the Coastal Flood Advisory due to minor tidal overflow from continued elevated tides and surf into at least Thursday.

* WHAT...Northeast winds 25 to 45 mph with gusts of 50 to 70 mph possible.

* WHERE...Eastern San Gabriel Mountains, Interstate 5 Corridor, Santa Susana Mountains, Western San Gabriel Mountains and Highway 14 Corridor, and Western Santa Monica Mountains Recreational Area.

* WHEN...From Thursday morning through Friday evening.

* IMPACTS...Damaging winds could blow down trees and power lines. Widespread power outages are possible. Travel could be difficult, especially for high profile vehicles.
