WEATHER forecasters are warning of thunderstorms and sudden flooding in York and North Yorkshire.

The Met Office issued a Yellow warning – Thunderstorm – for between 2am on Monday, August 12 to 1pm on the same day.

The UK’s national meteorological service issued the warning for most of the north of the UK and Northern Ireland.

It said thunderstorms may cause some disruption and damage to infrastructure on Monday.

The Met Office said although not all parts of the warning area are expected to see them, an area of increasingly organised thunderstorms is likely to produce a combination of frequent lightning, heavy rain, hail and short periods of strong winds.

The service said some torrential downpours are likely, with 20-40 mm in places, and a potential for 40-60 mm of rain to fall in one to two hours very locally, with hail up to two centimetres in diameter.

Forecasters warn of spray and sudden flooding which could lead to difficult driving conditions and some road closures and that there is a slight chance that power cuts could occur and other services to some home and businesses could be lost.

Thunderstorms are expected clear towards the northeast by Monday afternoon.
