Storm warnings for England and Wales extended 25 October 2013 Last updated at 16:48 Nick Miller explains where and when the storm is predicted to hit Warnings of stormy weather in England and Wales on Sunday night and Monday have been extended to more areas. A Met Office amber alert of high winds in southern Wales and southern England now includes much of the Midlands, the East, and London and the South East. People are being warned of the risk of falling trees and damage to buildings, with gusts of up to 80 mph (120 kph), possibly higher around exposed coasts There is also concern heavy rain could cause surface water flooding. A yellow alert predicting heavy rain on Monday covers the whole of England and Wales. It is the lowest level of the three warnings issued by the Met Office, and advises people to "be aware." An amber alert, advising people to "be prepared" for potentially hazardous conditions, is one level up from this. Significant disruption BBC Weather presenter Peter Gibbs said a strong Atlantic jet stream is providing the "driving force" for the storm, which is expected to hit central England and Wales UK late on Sunday night and run across the country in a north-eastwardly direction. The strongest winds are expected on the storms southern and western flanks. This storm doesn't exist at the moment, but our forecasts models predict it is likely to develop in the west Atlantic on Saturday End Quote Eddy Carroll Chief forecaster, Met Office Forecasters say a "very intense low pressure system" brings the potential for strong winds, especially on exposed coasts in Cornwall, Devon, Dorset, Hampshire, West Sussex, East Sussex and Kent. Temperatures of up to 15C on Monday will be above average. The Met Office said "the public should be prepared for the risk of falling trees as well as damage to buildings and other structures, bringing disruption to transport and power supplies." But there is still some uncertainty as to exactly when the storm will reach the country. Eddy Carroll, chief forecaster at the Met Office, said: "This storm doesn't exist at the moment, but our forecast models predict it is likely to develop in the west Atlantic on Saturday. Then it's likely to rapidly intensify just west of the UK late on Sunday before tracking across England and Wales early on Monday. There is still a chance this storm may take a more southerly track and miss the UK, bringing impacts elsewhere in northern Europe, but people should be aware there is a risk of severe weather and significant disruption. The AA said stormy conditions could cause "significant travel disruption on Monday morning... one of the busiest times on the roads." Darron Burness, head of the AA's flood rescue team, said: "Strong wind and torrential rain is an unpredictable and hazardous combination, which can be quite overwhelming when you're driving. There's likely to be tree and other debris on the roads as well potential flooding, so it's very important to keep your speed down and drive with great care.
