Fire Starts by the Numbers
While New Mexico has received enough rain to lift some fire restrictions, other parts of the southwest are still dry. That makes them vulnerable to lightning sparked fires, as well as human caused fires.
Humans start about half of the fires in the southwest. In southern California it’s a lot more -- about 90 percent are caused by people. Fire managers say the closer you get to a big city, where the population is dense, the more human caused fires. The top causes are unattended campfires, trash pile burning and arson.
Helene Cleveland is the fire prevention program manager for the U-S Forest Service. Cleveland says many people will leave their campsite thinking they have put out their fire.
"A number of people will pour water on it and they think all the hissing has stopped," Cleveland said. "They don’t see any smoke or steam rising from it and they think it’s ok. But what’s happening is there are embers deep down in, dry weather comes back around, the winds will pick up and sparks will fly."
Dry lightning can act much the same way. Clay Templin calls them sleepers, when lightning strikes and the embers smolder until the wind picks up. Templin is fire chief for the Tonto National Forest. He says this is the time of year when both dry lightning and humans keep him busy.
"You know it just takes a spark, especially when we’ve had this extended drought that we’re currently experiencing," Templin said. "It doesn’t take much for a fire to quickly gain in size.
Since late spring about 95-thousand acres have burned in Arizona.
