Storm Forecast Issued: 2010-08-22 22:36:00
Valid: 2010-08-23 00:00:00 - 2010-08-23 23:59:00

Regions Affected
N + S Scotland, Northern Ireland, N England, N Wales, Yorkshire, Midlands + East Anglia (all of the United Kingdom is included in the WATCH)

Synopsis

An unseasonably deep area of Low pressure, Beate (FU Berlin), moves northeastwards across England during the morning hours, deepening all the while.

In the warm sector, convection is possible leading to isolated thunderstorms developing during the early hours perhaps across parts of CS/SE England into East Anglia. Conditions will be favourable for the development of a tornado, perhaps strong in nature, this risk greatest at the Triple Point. Any storms that do develop in the warm sector will continue to move NE/ENE across the North Sea during daylight hours towards Scandinavia by evening.

As "Beate" continues to deepen in the morning, wind gusts of up to 50mph are possible along some eastern and southeastern coastlines for a few hours during the morning, before moderating.

In the following rPm airmass, widespread showers and thunderstorms are expected to develop across many parts of central and northern Britain. With lighter winds here, showers will be prolonged and may merge into longer spells of rain, increasing the threat of flash flooding. Given the airmass, hail is likely in many showers, locally moderate in size.

Showers will decrease in coverage during the evening hours, though will persist quite widely across Scotland and the North Sea overnight.
