Overview

• A 37-hour yellow rain warning is in place for western Scotland from Wednesday 5 p.m. to Friday 6 a.m., with up to about 250mm possible on the highest ground.
• The US National Hurricane Center expects Humberto to become post-tropical by Thursday, yet its remnants could still bring strong winds and hazardous seas.
• Forecasters caution that the system’s development and path remain uncertain, and additional UK alerts may be issued as confidence grows.
• Unsettled, wet and windy conditions are expected to spread more widely from Friday into the weekend, with some model outputs suggesting initial impacts in Northern Ireland before reaching Wales and Scotland.
• Interaction between Humberto and nearby Imelda may influence the storm’s evolution, and some experts suggest a UK named storm is possible, though none has been designated.
