The National Meteorological Agency (Aemet) has activated orange warnings (high risk) for the Canary Islands for maximum wind gusts that could exceed 90 kilometres per hour and yellow warnings (risk) for rainfall that could leave up to 60 litres per square metre in twelve hours and winds of up to 70 km/h. The interaction of a subtropical air mass with a cold mass associated with a squall in the Canary Islands on Tuesday and Wednesday will cause an increase in instability.
The orange warning for maximum wind gusts of 90 km/h is in force next Tuesday, 6 June, from 00:00 to 23:59 on the islands of La Palma and Tenerife, mainly affecting the north-west slope and peaks and the municipality of El Paso.
On the same day, a yellow warning of gusts of more than 70 km/h is also in force on La Gomera and El Hierro, mainly on the peaks and northwest and southeast slopes of the two islands.
As for rain, Aemet has issued a yellow warning for the western islands and Gran Canaria. Thus, on the peaks and in the west of La Palma, up to 60 litres per square metre of precipitation could fall in 12 hours. On La Gomera, El Hierro and in the east, south and west of Tenerife and Gran Canaria, up to 15 litres per square metre could fall in one hour.
The triggering of these warnings is a result of the interaction of a subtropical air mass (warm and humid) with a cold mass associated with an Atlantic wind gust that will cause an increase in instability around the Canary Islands on Tuesday and Wednesday. Precipitation will be more likely and heavier on the islands with greater relief.
