From a different source in Spanish, updated yesterday: https://www.eldiario.es/canariasahora/sociedad/tenerife-no-descansa-espera-lluvia-milagrosa-despierto-hora-ver-avanza-fuego_1_10454461.html
It is a sixth generation wildfire never seen before in Canarias, a consequence of climate change: “The island has gone through a very important rainfall deficit and a heatwave without precedents.”
The fire has ravaged over 8400 hectares. The fire has reached an extension of 70km long perimeter since last Thursday, and has forced over 12600 people out of their homes.
I like the implication that Spanish firefighters are middle aged men with a garden hose in shorts and A-shirts
