It really doesn't look good. The island government has closed the main road through the forest between the junction for the road to Playa Santiago and La Laguna Grande, as well as two secondary roads. Traveling to and from Valle Gran Rey  now involves a detour via 
Hermigua and Vallehermoso.
They also have declared a level 2 emergency which means that the coordination passes from the island government to the central Canary government.
More news later, got to work now.
