1,300km wide dust cloud bigger than the UK is moving across the Canary Islands
The Canary Islands have entered a pre-alert for calima, as a massive cloud of Saharan dust moves across the archipelago. While forecasters had already warned it was on the way, dust levels have now become more noticeable, especially in Lanzarote and Fuerteventura.
Experts analysing satellite images say this is no ordinary calima, as the cloud coming in from Africa is around 1,300 kilometres wide. To give an idea of its size, that’s more that the length of the UK from John O’Groats to Lands End.
Strong winds of up to 80 km/h have swept the dust into the air and are pushed it towards the Canary Islands.
The calima is expected to spread across all the Canary Islands, with conditions getting worse before they improve:
- Today (Tuesday): Dust is already affecting the eastern islands and spreading across the rest of the archipelago.
- Peak conditions: The worst of the calima is expected from midday onwards, with visibility dropping to around 3,000 metres in some areas and at altitude.
- Wednesday (1st April): Conditions should begin to improve in the eastern islands, but will linger in Gran Canaria, Tenerife, and the western islands until the evening.
Health and Travel Advice
Authorities are warning both residents and tourists to take care during the calima.
· People are advised to keep windows and doors closed, avoid heavy exercise outdoors, and take extra care if they suffer from breathing problems.
· Drivers should reduce speed and use headlights in areas of poor visibility, especially on mountain roads.
· Anyone feeling unwell should seek medical advice or call the 012 information line.
The situation is being closely monitored as the islands are expected to experience one of the most significant calimas for several years.
