Issued Sat 28/04/2012 1700GMT
Areas affected - Gales - Wales and Southwest England
Heavy Rain - Wales, most of England
Valid from: 1800GMT Saturday 28th April 2012 - 1159GMT Monday 30th April 2012
General evolution: A low pressure system develops over western France to ~986mb into the southwest approaches through Sunday, combining a warm occluding frontal zone with current static frontal rainfall over southern and eastern England. A deeply saturated warm profile advected over an intensifying circulation gives winds up to F8. The low fills and moves slowly west into Monday, whilst the occluded front continues north weakening progressively.
Forecast: Convectively enhanced intense rainfall is expected across southwest England and Wales through Sunday morning, with accumulations up to 40mm and possibly greater over high ground. This as a result of northeasterly gales within the frontal zone of greater than 40mph over exposed high ground and coasts of southwest England and most of Wales, with gusts associated with the most intense rain up to 60mph. Elsewhere across England, accumulations of rain up to 20mm generally, while 30mm possible across high ground and parts of the Midlands, with average winds generally below 40mph but possibly gusting to over 50mph in exposed or elevated areas. Given recent and current rainfall, ground saturation and river levels give rise to concerns for both surface and catchment flooding through Sunday. Gusts may be damaging in exposed areas, this being more likely due to the wind coming from the NE.
