WET WEATHER CONTINUES - 10/17/05
An upper-level low is centered 300 nautical miles SSW of Los Angeles. The counter-clockwise circulation around this low has brought strong winds to the mountains along with rain showers and thunderstorms. Rain and thunderstorms this morning have prompted the issuance of flood warnings for the recent Harvard and Topanga burn areas. Earlier this morning, an east-west band of showers set up over the burn areas and, although individual showers are light enough not to produce immediate flash flooding and debris flows, the continuous training of showers over the same areas raises the potential for flooding to where warnings are required.
Showers are expected to diminish later this morning, but redevelop later this afternoon and tonight as the upper-level low begins to move north and east towards San Diego County. Therefore, the threat for more heavy rain will continue later today and through early Tuesday. This threat has prompted the issuance of a flash flood watch for both Ventura and Los Angeles Counties from now through mid-day Tuesday.
The storm system is expected to move into Arizona on Wednesday, taking the rain with it. Therefore, look for improving conditions from the south and west on Tuesday with sunny skies becoming more widespread on Wednesday. Snow levels are very high (above 8000 feet). Very strong winds are occuring in the mountains of Ventura and Los Angeles County this morning. Most wind gusts are in the 35-45 MPH range, but isolated areas like Warm Springs and Chilao have continued to gust above 50 MPH, occasionaly gusting as high as 70 MPH. We will stick with the wind advisory this morning, but isolated gusts above advisory criteria will be possible during the morning hours.
