The graph at right shows the wind speeds at our home, in MPH (multiply by 1.6 to get KPH). The green line shows the running 5-minute average; the red line the peak gusts. Note that my wind sensor is a conventional rotating-cup anemometer, and is therefore not very responsive to very short gusts – something we seem to have a lot of in a Santa Ana wind condition.You can see that the average wind today is much higher than normal (as was Saturday, though not quite as high as today). Still, compared to a “normal”, this is very mild. It's also a very cool Santa Ana – instead of temperatures in the 90°F (32°C), our high today was just 74°F (23°C). And that's just fine with me! About the most dangerous part of this Santa Ana is the very low relative humidity (as low as 2.1%RH today).
At right is the view from the Lyons Peak camera looking north (a view that includes our home). Those clear blue skies are what we want to see on a Santa Ana day – no nearby smoke plumes. However, toward the left side of the photo, just above the horizon, you can see an ugly gray smudge – this must be the fires on Camp Pendleton or in Los Angeles, far to the north of us.As always, click on a photo to get a larger view...
