Flash floods have swept through Nepal’s central Gorkha district after a pre-dawn landslide on 11 October blocked the Budhi Gandaki River, triggering severe downstream flooding. Two villages in the worst-affected Chumanubri rural municipality were reportedly destroyed, with homes, roads and bridges washed away. Part of a hydropower station was also damaged.

After river levels surged from 2 metres to nearly 8.5 metres within hours, the national disaster risk reduction and management authority reported that 204 homes were damaged, and more than 650 people had been affected. More than 100 foreign trekkers were stranded in the popular hiking region. The floods come just two months after catastrophic flooding and landslides devastated parts of the country on the border with Tibet, leaving thousands dead or missing.

An exceptionally deep area of low pressure barrelled towards Iceland this week. The central pressure was measured at 931mb on 14 October. The pressure plummeted by 49mb in 24 hours, meeting the thresholds for explosive cyclogenesis, or a weather bomb. The system brought sustained winds of 55–60mph to the southern shores of the island before moving north-east through the North Atlantic towards Norway.

However, Iceland was spared the strongest winds as the track of the storm meant they remained out at sea. The system also affected areas beyond Iceland: a 108mph gust was recorded at Bealach Na Bà, in the Scottish Highlands, in association with a trailing 1,000-mile cold front that stretched from Norway to the mid-Atlantic.

Summer-like conditions have extended even further into meteorological autumn in Portugal. After temperatures of 40C at the end of September, on 14 October a maximum of 35.6C was recorded in the southern town of Mora, representing a climatological anomaly of more than 10C.

The heat was not localised, with numerous stations recording temperatures well into the mid-30s celsius. The latest forecasts show that the high pressure and unseasonably warm upper air temperatures will remain in place for the next few days. Looking further ahead, however, temperatures are expected to slowly return towards the average around the middle of next week.
