We have ranted about San Diego Gas and Electric a number of times for starting numerous wildfires, including the disastrous Witch, Rice, and Guejito fires in eastern San Diego County in 2007. But we have to give them credit for doing two things recently that benefit the wildland fire community.
The first was the purchase of a $30 million Erickson Air-Crane S64F Helitanker that should be delivered later this month. The company has agreed to share it with San Diego County on wildfires for a reasonable cost, but it will be used primarily for constructing and maintaining power lines.
The second thing they have done is to install a boatload of weather stations in the backcountry areas of San Diego County, including Ramona, Alpine, El Cajon, Valley Center and Fallbrook. So far they have have installed 94, yes 94, weather stations on power poles in wind-prone areas. The solar-powered stations contain sensors and data loggers made by RM Young and Campbell Scientific, respectively, and monitor wind speed, wind direction, temperature, and relative humidity.
SDG&E intends to use the data from the stations to determine where it should stage repair crews and whether or not it should shut off power to residents during periods of strong winds.
The meteorologists in the local National Weather Service office are pretty excited about this massive new source of weather conditions. SDG&E has plans to make the data available to the public through a “dashboard”.
