UK weather: a month's rain could fall in two hours as heatwave breaks

Fears of flash flooding in parts of country, while experts warn extreme heat could become the norm

Over a month's worth of rain could fall within two hours on parts of Britain this week, causing flash flooding, while an ongoing heatwave is set to break records.

Police and the coastguard issued warnings over the weekend as two people died - a woman after a collision between a jet ski and a boat in north Wales, and a man believed to have drowned in a lake at a Norfolk beauty spot.
