Los Angeles is on high alert as the National Weather Service has issued multiple warnings for extreme weather conditions, which include a high wind warning, an air quality alert, and a red flag warning effective through various parts of Wednesday. According to the extended forecast, today's sunny skies come with the peril of very windy conditions, north-northeast wind gusting as high as 55 mph, which are expected to decrease later in the afternoon.
In the evening, the North northeast wind is to substantially slacken down to 5 to 10 mph, leading into a series of clear and sunny days, with highs ranging from 64 to 74 degrees Fahrenheit, as well as relatively calmer winds as reported by the National Weather Service. The "High Wind Warning" issued by the National Weather Service remains in effect until 6 PM PST this evening. With northerly winds 30 to 40 mph and gusts even reaching up to 60 mph in certain areas causing potential risks like downing trees and power lines, resulting in widespread power outages, and making travel particularly difficult for high profile vehicles - especially in areas like Beverly Hills, Torrance, Long Beach, and the Hollywood Hills which have the highest chances for strong and damaging winds, including gusts over 55 mph in areas adjacent to the Sepulveda Pass, as per the NWS High Wind Warning.
Alongside the wind advisory, the South Coast Air Quality Management District issued an air quality alert until 5 PM PST Wednesday due to increased fine particle pollution from wildfire smoke which can cause serious health problems such as heart attacks, strokes, and difficulty breathing. The alert notably covers the San Gabriel Valley, Santa Monica Mountains, and the Los Angeles County coastal areas where residents are advised to stay indoors and limit exposure due to the particulate matter from the wildfires' smoke.
The National Weather Service has also emphasized the severity of the current windstorm, marking it as a "Particularly Dangerous Situation" (PDS), accompanying the red flag warning in effect until 4 PM PST Wednesday, connecting it to the destructive 2011 windstorm that significantly impacted Pasadena and the San Gabriel Valley, the windstorm is likely to result in downed trees and powerlines, as well as widespread power outages. The hazardous conditions are expected to encourage very rapid fire spread, extreme fire behavior, and extended range spotting which substantially increases risks to life and property, especially in highly vulnerable areas such as those along the Highway 118 and 210 corridors.
