The Met Office has a yellow warning from 8pm. on Sunday until 4 a.m. Monday, with the weather potentially causing some localized disruption. The warning covers London and south-east England, south-west England, most of Northern Ireland, large parts of Wales, east of England, Northamptonshire and Warwickshire. There is a high chance that driving conditions will be affected by spray or hail, and there will likely be damage to buildings and structures from lightning and gale force winds. Flooding of homes and businesses is possible and there may be delays to train services. Forecasters say some short-term loss of power and other services is also possible. The Met Office said heavy rain and thunderstorms were expected to develop across south-west England on Sunday and move north into parts of Wales and Northern Ireland. They are expected to clear up in the early hours of Monday. A separate area of storms is likely to develop across central southern England late in the evening, moving north towards midnight overnight. Some places may see 20mm to 30mm of rain in less than an hour, while other places may not get much rainfall at all. Forecasters said frequent lightning, hail and locally gusty winds could accompany stronger storms, particularly in south-west parts of England and Wales.
