Rain in San Sebastian de La Gomera recently
Yet another low pressure system is beginning to form north of the Canary Islands and has been named 'Therese'. This depression comes after an unusually cold winter which on the positive side has brought copious rainfalls after several years of drought.
Storm Therese's exact track is still a bit uncertain, but it will most likely affect the Canarian archipelago from Tuesday afternoon, March 17th 2025, and could last until early next week. Some models suggest it could pass right over these islands on Sunday while beginning fo fill, but that is too far ahead for a reliable forecast.
Anyway it is best to be prepared for intense rainfalls, resulting rockfalls, gusty high winds (predominantly westerly), thunderstorms, very high waves with rough seas and colder than normal temperatures with snow on the highest peaks. At least some disruption can be expected and a few larger events like the 'Tecnologica' festival in Tenerife have already been postponed.
It is expected that several official alerts and warnings will be issued once more detail is known, but it definitely won't be hiking nor beach weather for several days.
You have been warned...
Update March 17th 2026:
The depression is now expected to be situated just W-NW of Madeira on Thursday with a pressure of around 982 hPa. The first warnings (below) have been issued by the Spanish meteorological service (aemet.es click this for their latest updates), and further warnings are expected for the following days.
