Borrasca Claudia’s Impact: A Tale of Two Islands in the Canary Archipelago

The recent storm, dubbed Borrasca Claudia, has left a mixed legacy across the Canary Islands, with Tenerife experiencing significantly less rainfall than anticipated while La Palma faced much heavier showers. The storm’s effects were felt differently across the islands, showcasing the unique weather patterns that can occur in this region.

Unexpectedly Light Rainfall on Tenerife

During the night, the island of Tenerife saw a surprisingly calm atmosphere, with sporadic showers occurring primarily in the southwestern regions, including Santiago del Teide and Vilaflor. Despite initial forecasts predicting more severe weather, the total rainfall recorded on the island did not exceed 20 litres per square metre. This mild impact has left many residents relieved, as the storm’s intensity was far less than what was initially expected.

In contrast, the neighboring island of Gran Canaria was not as fortunate. Reports indicated that between five and six in the morning, San Bartolomé de Tirajana experienced a deluge, receiving up to 78.4 litres per square metre, while Vega de San Mateo recorded a substantial 63.8 litres. This stark difference in rainfall highlights the unpredictable nature of Borrasca Claudia and its varying effects across the islands.

Strong Winds and Their Consequences

While rainfall was minimal in Tenerife, the storm brought with it strong winds that posed significant challenges, particularly in elevated areas of La Palma, La Gomera, and Tenerife itself. Wind speeds reached alarming levels, with Vallehermoso in La Gomera recording gusts of 95 kilometres per hour, Izaña in Teide National Park measuring 94 kilometres per hour, and Roque de los Muchachos in La Palma registering gusts of 90 kilometres per hour. These powerful winds not only created hazardous conditions but also contributed to various incidents across the islands.

La Palma’s Heavy Showers

As Borrasca Claudia moved away from the Canary Islands on Thursday morning, La Palma was left with a more substantial amount of rainfall, with some areas experiencing over 100 litres per square metre, particularly in the Valle de Aridane region. This significant rainfall has raised concerns about potential flooding and landslides, prompting local authorities to remain vigilant.

Despite the relatively minor impact on Tenerife, local authorities had proactively taken precautions in anticipation of severe weather. The local council increased the number of emergency personnel from 150 to 454 to ensure readiness for any potential emergencies. This strategic move underscores the importance of preparedness in the face of unpredictable weather events.

Minor Incidents Amid the Storm

Throughout the storm, incidents reported across Tenerife were mostly minor, primarily linked to wind-related issues. These included fallen panels, road closures, and preventive evacuations. Notably, lightweight structures collapsed in Granadilla de Abona due to winds exceeding 50 kilometres per hour, and road closures were enforced on Tierra del Trigo in Los Silos starting Wednesday afternoon. Such incidents, while not catastrophic, highlight the storm’s impact on local infrastructure and the need for ongoing vigilance.

Additionally, a whirlwind caused damage to a greenhouse roof in Güímar, further illustrating the storm’s effects on agricultural structures. These incidents serve as a reminder of the potential dangers posed by severe weather, even when the rainfall itself is less than expected.

Evacuations and Educational Disruptions

A group of tourists was evacuated from the Chipeque viewpoint after ignoring closure warnings related to the storm. This incident is not the first of its kind, as similar situations have occurred in the past, raising concerns about public safety during adverse weather conditions. Authorities continue to emphasize the importance of adhering to safety guidelines during storms to prevent unnecessary risks.

In the aftermath of the storm, classes were suspended on Thursday, transitioning to an online format for students. This decision was made to ensure the safety of students and staff, as authorities assess the situation. Updates regarding the reopening of trails, forest tracks, and recreational areas are expected throughout the day, as officials work to restore normalcy.

Weather Forecast for the Day Ahead

Although the main body of Borrasca Claudia is moving eastward, meteorological forecasts indicate that some precipitation may persist on Thursday, particularly in the interior west and mid-altitude areas of Anaga and the northwest of Tenerife. As the day progresses, moderate rainfall is expected to continue in the northern regions, while clearer skies are anticipated in other parts of the island. Residents are advised to remain cautious and stay informed about changing weather conditions.
