The remnants of Hurricane Ernesto are forecasted to bring severe weather to the UK, with heavy rain and wind gusts up to 60mph expected from Wednesday. The Met Office has issued multiple yellow warnings for rain, primarily affecting Scotland but extending as far south as London, with potential flooding and travel disruptions. Ernesto, which previously caused widespread power outages in Puerto Rico and Bermuda, is transitioning into a typical low-pressure system as it moves over cooler waters. Additionally, smoke from North American wildfires has caused unusual haze and vibrant sunsets in the UK. The unsettled weather is expected to disrupt the remaining summer days, although warmer and less wet conditions are predicted for the southeast. The public is advised to remain vigilant for weather updates and potential hazards.
