Severe Rainfall Triggers Flash Floods in Lisbon: Loures and Odivelas Hit Hardest

Intense Rainfall Causes Major Disruptions in Lisbon

This Saturday afternoon, the Greater Lisbon area experienced a sudden episode of intense rainfall that led to widespread flash flooding. Emergency services were mobilized to rescue people stranded in their homes and vehicles.

According to Hugo Santos, the Sub-regional Commander for Emergency and Civil Protection in Greater Lisbon, there were 97 reported incidents from 12:00 PM to 6:30 PM, primarily involving flooding on public roads, roadways, and some residences.

The municipalities of Odivelas and Loures were the most affected, with Loures experiencing water overflow from streams coinciding with high tide at the Trancão River.

“Currently, between 30 to 40 people are being relocated to safe and dry areas after being isolated due to the intense rain,” Santos stated, noting that operations were still underway by 7:00 PM.

In Loures, Camarate Fire Commander Luís Martins described the situation as “40 minutes of terror.” He reported that even their unit was completely flooded, making it impossible to use their vehicles. They received 60 emergency calls simultaneously, prioritizing the rescue of individuals in need.

Residents showcased the extent of the damage, with reports of significant hail accumulation following the storm.

The city of Lisbon also faced challenges, as the Second Circular was partially blocked due to water accumulation, rendering two lanes impassable. Meanwhile, the Lisbon Metro announced interruptions on the yellow line between Senhor Roubado and Rato stations, although the cause was unrelated to the rain.

Overall, 264 incidents were reported across mainland Portugal from midnight to 6:00 PM, primarily involving flooding, tree falls, and structural collapses. Most incidents occurred in the Lisbon and Tagus Valley region.

The Portuguese Institute of the Sea and Atmosphere (IPMA) has issued a yellow warning for all districts in mainland Portugal due to forecasts of heavy showers, with the potential for thunderstorms and hail. This warning, the least severe on a three-tier scale, indicates a risk for weather-dependent activities. Weather forecasts predict cloudy skies with sporadic heavy rain and hail, gradually decreasing in intensity from the coast inland.

Additionally, moderate winds are expected.
