Storm Therese Batters Madeira: 116 Emergencies and a Suspected Tornado on Porto Santo

The Atlantic depression Therese has been pounding the Madeira archipelago since Thursday, and the damage toll continues to climb. By Sunday morning, the regional Civil Protection service had logged 116 weather-related emergencies across the islands, deploying 301 personnel and 139 vehicles in the largest storm response Madeira has seen this year.

The numbers tell a grim story of nature's force: 26 landslides, 22 fallen trees, 17 floods, ten collapses of building elements, five downed power lines, three structural failures, and two cave-ins. Remarkably, no injuries or fatalities have been reported, a fact authorities attribute to improved early-warning systems and swift municipal response.

Porto Santo's 20 Minutes of Fury

The small island of Porto Santo bore a disproportionate share of the punishment. On Friday evening, what the Portuguese meteorological institute IPMA described as an "extreme meteorological phenomenon" struck the island. A convective cell unleashed 20 minutes of torrential rain, toppling trees, flooding buildings, and leaving a trail of destruction that generated 28 emergency calls in rapid succession.

IPMA's regional delegate went further, suggesting the event may have been a tornado, though formal confirmation is still pending. The Campo de Baixo primary school sustained enough damage to force closure until at least Wednesday, March 25, leaving parents scrambling for childcare arrangements.

Funchal and the South Coast Hit Hardest

On the main island, the southern coastal municipalities bore the brunt. Funchal recorded 28 emergencies, matching Porto Santo's total. Camara de Lobos followed with 15, Santa Cruz with 13, and Machico with 11. The northern coast fared somewhat better, though Santana and Porto Moniz each registered four incidents.

Several roads remain closed or restricted, complicating movement across an island where mountainous terrain already limits alternative routes. IPMA maintained a yellow alert for Sunday, warning of further heavy showers accompanied by thunderstorms.

What It Means for Residents and Visitors

For the thousands of foreign residents and regular visitors who call Madeira home or a frequent destination, Storm Therese is a pointed reminder that the subtropical archipelago is not immune to severe weather. The island's steep terrain and narrow valleys make it particularly vulnerable to flash flooding and landslides during intense rainfall events.

The 2010 Madeira floods, which killed 47 people, led to significant investment in drainage and early-warning infrastructure. That investment appears to be paying off: despite the volume of incidents, the absence of casualties in this event suggests the systems are working. But with climate patterns shifting and Atlantic storms potentially intensifying, the question of long-term resilience remains very much open.

Authorities urge anyone in affected areas to monitor IPMA alerts, avoid unnecessary travel on mountain roads, and report any structural damage to local Civil Protection offices.
