Forecasters believe the worst of the thundery downpours have passed, after a clutch of east Norfolk villages experienced localised flooding yesterday.

On the A47 at Acle drivers said so much hail had gathered on the road it looked like snow, while others reported flooding on roads in Caister, Martham and routes between Rollesby and Caister.

Heavy showers are expected today with 11mm measured at Marham between noon and 1pm.

But Jim Bacon, managing director at Norwich's WeatherQuest, said things had calmed since yesterday afternoon.

'It was much quieter overnight,' he said. 'The main rainfall events were during the day time.

'The ability of a fairly sparse observation network to catch the heaviest rain is a pretty big ask.

'The heaviest we recorded was 16.8mm at Norwich Airport.'

While the total could have been higher at locations such as Hemsby, there was no formal observation.

'The totals weren't extreme, even the Norwich Airport one, but that amount of rain fell in about an hour,' added Mr Bacon.

The amount recorded at Norwich Airport would ordinarily fall over a week.

Mr Bacon said there was a chance of showers today but cloud was moving south with Norfolk drier later.

He added there was a possibility of rain tomorrow, but added: 'I don't think they will be those intense thundery downpours.'
