Flood alerts issued for most of UK for Saturday

Severe weather warnings have been issued for Saturday, with some areas of Britain expected to see nearly half an entire month's rainfall in just an hour, the Guardian reported.

The Environment Agency has issued "low risk" flood alerts for most of the UK.

The Met Office said thundery rain was expected to begin early in the morning, with showers likely until the evening.

Some areas could see 2cm to 3cm of rain in an hour – almost half of the UK monthly average for the whole of June of 7.3cm. The cause is warm, humid air moving in from Europe which creates a risk of downpours when it mixes with cooler air over the UK.

Met Office spokesman Dan Williams said the downpours would be "pretty heavy". He said: "We are looking at the potential for some localised flooding because the downpours are potentially heavy enough that we could see so much rain fall in a short space of time that it can't drain away fast enough."
