Storm Therese struck the Canary Islands on March 21, 2026, causing multiple incidents. In Gran Canaria, precautionary evacuations occurred in the neighborhoods of Los Pérez and El Hornillo, in the municipality of Agaete (per EL PAÍS) or Artenara (per eldiario.es), near the Los Pérez reservoir, due to rising water levels. An elderly man was rescued from his flooded home in Barranco Hondo, Gáldar. In Tejeda, a 15-ton rock fell, closing the GC-60 road. Gran Canaria's Cabildo raised the emergency to level 1 and closed access to Guiniguada ravine in Las Palmas, where three people were rescued. Rainfall reached 103.2 l/m² in Vega de San Mateo and up to 212 l/m² in Cruz de Tea, Tenerife. In Tenerife, flooding hit homes in Buenavista del Norte, El Médano, and Los Silos, with rockfalls in Los Blanquitos and 10-20 cm snow in highlands. Wind gusts hit 200 km/h at Teide. Air traffic saw 24 cancellations and three diversions, mainly at Santa Cruz de La Palma airport. The Emergency Coordination Center logged 1,105 incidents and six injuries. Prime Minister Pedro Sánchez tweeted: “We are closely monitoring the evolution of #BorrascaTherese [...] Much caution and avoid unnecessary travel.” Aemet forecasts instability on Sunday. The Canary Islands Government activated alerts for flooding and rockfalls in western islands and Gran Canaria.
