The Meteorological Chronicles of February 1971 in the Canary Islands

February 12, 1971 — A date etched in the memories of the residents of the Canary Islands due to extraordinary meteorological phenomena that swept across the archipelago. This article delves into the events of that month, highlighting significant rainfall and unique weather patterns, as well as their implications for the islands.

Intense Rainfall and Records

On that fateful day, various measurement stations across the islands reported astonishing rainfall figures. For example, Izaña recorded a staggering 197 mm of precipitation, primarily in the form of snow. This high-altitude area saw snowfall reach up to one meter in thickness, an exceptional event for a region that typically experiences milder winter conditions.

Rainfall data from other stations also reflected similar extremes. The mountains of Gran Canaria experienced record-breaking accumulations:

• Dana over the Archipelago included Valleseco (198.6 mm) and Moya (136.5 mm), both grappling with significant downpours.

The sheer volume of rain sparked not only wonder but also concern, as many areas witnessed dramatic shifts in landscape caused by heavy clustering of precipitation. Certain regions, such as El Hierro, recorded snowfalls, which are infrequent and usually unexpected for this particular island.

A Meteorological Ruckus: February’s Tempestuous Nature

The second half of February continued the trend set by the earlier days. The 1971 Weather Events across the Canary Islands were characterized by thunderstorms and intense rainfall that often exceeded 200 l/m² within a mere 24 hours. Areas such as Güimar were particularly affected by heavy hail, while Las Palmas de Gran Canaria faced severe challenges with flooding.

This tempest was not merely limited to Gran Canaria. Across the islands, lesser-known places felt the brunt:

• La Palma and Tenerife saw breathtaking snowfall in their mountainous regions, with places above 900 meters experiencing some of the heaviest snowfall.

Unusual Weather Patterns

Interestingly, February 1971 was only the beginning of unusual weather that would be reported throughout the year. On February 26, Izaña recorded a remarkable minimum temperature of -9.8 °C, a significant climatic event for a location not known for extreme cold. This cold snap further exemplified the bizarre weather oscillating between winter chills and spring-like warmth.

Unseasonable conditions also prompted warnings and precautionary measures from local governments. The cascading effects of heavy rainfall led to blockages and possible landslides, prompting emergency responses in several communities.

Rare Weather Phenomena and Public Impact

These weather phenomena triggered a domino effect across various sectors. For instance, during this time, the community noted how consumers rapidly shifted their activities. People adapted to the unpredictable conditions; farmers worried about their crops, while families faced potential disruptions to daily life due to infrastructural damage caused by torrential rains.

Eyewitnesses described a scene of chaos, with residents reporting trembling buildings, flooded streets, and widespread caution among locals trying to navigate through the unusual weather. The emotional impact was palpable, as many sought refuge and reassured themselves amid the tempest.

Conclusion: A Prelude to Future Weather Events

While records were shattered in February 1971, this weather did not stand alone. As the year progressed, heavy storms continued to impact the islands, marked by the April 9th rainfall resulting from a low-pressure system that pounded various locations. A sustained pattern emerged throughout the year with notable precipitation recorded in subsequent months, culminating in a dynamic meteorological narrative interwoven into the everyday lives of the archipelago’s inhabitants.

As residents reflected on the tumultuous February 1971, they could also prepare for future challenges that climatic changes would inevitably bring.

With over half a century since those extraordinary events, the meteorological history of the Canary Islands serves as a testament to the unpredictable beauty of nature, urging continued observation and adaptation to its mercurial rhythms.
