The Met Office has issued a yellow warning for rain until tomorrow morning with forecasters predicting that up to two inches of rain could fall in a short time, leading to surface water flooding. Lightning and hail may also prove to be additional hazards, weathermen warn. The Met Offices chief forecaster said: Heavy showers and thunderstorms are likely to continue northwards on Friday morning - the risk then continuing through the rest of the day. Many places will miss these but the public should be aware of the potential for isolated disruption due to surface water flooding, lightning strikes and hail. Further heavy showers and thunderstorms are likely to continue through Friday night and into Saturday morning, with the main risk receding eastwards to become mostly confined to the east of the yellow area by then.
