Updated 3 October: As Lorenzo moves away from the Azores towards Ireland, the hurricane’s effect on the Alisios is diminishing and the blast of hot air from the Sahara is again able to be blocked. As a result, the Canarian Government has tonight lifted its forest fire risk alert with cooler weather approaching.
Original post 29 September: Given the hot weather due to Hurricane Lorenzo bypassing the Canaries, the Canarian Government’s Emergencies Board has declared a forest fire risk alert in Tenerife, as well as in El Hierro, La Palma, La Gomera and Gran Canaria. As usual it is the three 30s – temperatures above 30º, winds over 30 km/H, and humidity below 30% – that present the main problem. All the usual prohibitions and cautions apply while conditions prevail.
