Eastern Spain Braces for Torrential Rain Amid Global Extreme Weather Events

Eastern Spain is preparing for torrential rain and potentially damaging flooding in the coming days, as a weather phenomenon known as a Dana develops. This pattern, which typically occurs in autumn, involves cold upper air moving over the warm, humid surface air of the Mediterranean Sea, fueling violent, slow-moving thunderstorms near Spain’s east coast. Weather models indicate that more than 100mm of rain could fall across the region on Friday, with some areas potentially receiving 200-300mm. Cities like Valencia and Castelló de la Plana are identified as most at risk, particularly Valencia, which has experienced several damaging floods in recent years. In response, Catalonia has placed three towns under lockdown, and Valencia has closed schools for nearly half a million children.

Concurrently, Nepal has been severely impacted by heavy rainfall this week, between September 24 and 27, leading to widespread disaster. The National Disaster Risk Reduction and Management Authority reported 542 disaster incidents, including 304 landslides and 87 linked to flooding, resulting in 27 fatalities. During this period, 186 meteorological sites recorded over 100mm of rainfall, with Dedhgaun in Lumbini province experiencing an extreme 544.2mm. Authorities issued SMS flood warnings to nearly a million people and relocated 2,000 individuals residing in high-risk areas as a precautionary measure.

The heavy rainfall in the region also affected the Gandak River in Bihar, north-east India, which reached a record water level of 91.25 metres on Tuesday. This level surpassed the previous record, set in 2024, by 0.35 metres, according to the water resources department. Emergency teams have been deployed along the river, repairing 169 seepage points along the embankments, which continue to face significant water pressure.

Separately, the north-east United States was hit by a nor’easter on Saturday, marking the first such storm of the autumn/winter season. This very deep area of low pressure brought strong winds, heavy rainfall, and coastal flooding, with gusts reaching up to 74mph (119km/h) and waves rising to 3 metres. The storm left approximately 200,000 people without power, inundated streets in New York City, and caused one fatality when a tree fell in Brooklyn. Amidst the storm's impact, a piece of history was uncovered as the wreckage of the Warren Sawyer, a three-masted ship destroyed in 1884, washed ashore on Nantucket, off Cape Cod in Massachusetts.
