A sudden change in weather conditions in the Canary Islands over the coming days could impact transport, power supply, and daily life. The formation of the powerful Atlantic storm Therese is already causing concern among locals and tourists. According to russpain.com, such weather events can lead to disruptions at ports and airports, as well as temporary restrictions on travel between the islands.
The week will start off relatively calm across the archipelago, but brief showers are possible in some areas by Monday evening. This will be especially noticeable in northern Tenerife, where local thunderstorms are likely after noon. Meanwhile, Lanzarote and Fuerteventura will come under the influence of cloud fronts, bringing rain during the second half of the day.
Intensification of severe weather
On Tuesday, conditions will start to change: an isolated cold depression, Therese, is forming over the Azores and gradually moving towards the Canaries. While weather remains stable on mainland Spain, the western islands will see rain begin in the morning and spread to most of the region by evening. Local authorities warn of the possibility of stronger winds and reduced visibility on the roads.
Wednesday will be a turning point: Storm Therese will fully form and bring with it active frontal systems. A cold front will sweep across all the islands, causing prolonged and intense rainfall. Tenerife is expected to see the heaviest precipitation, with possible hail and thunderstorms. Winds will strengthen to dangerous levels, especially on La Palma, Tenerife, and Gran Canaria, where gusts may exceed 70 km/h. The western coasts will face a maritime storm with waves up to 4 meters high.
Regional impact
On Thursday, another, more active front associated with Storm Therese will again cover the Canary Islands. The heaviest downpours are forecast for La Palma and Tenerife, where a significant amount of rain may fall in a short period. This raises the risk of localized flooding and disruptions to infrastructure. Unstable weather will persist throughout the week, and by the weekend, the center of the storm may move directly over the archipelago, leading to further intensification of rain and wind.
According to RUSSPAIN, such weather events are rare in the Canary Islands, but recent years have seen an increase in storms with strong winds and heavy rains. In 2023, a similar storm caused ferry disruptions and temporary road closures. Local authorities advise monitoring forecast updates and taking precautions when weather conditions worsen.
