Further heavy rain expected in the wake of Storm Dennis
Although the severe weather associated with Storm Dennis has passed, there is further wet and windy weather to come this week.
With much of the ground around the UK saturated from heavy rain over the last two weeks, further severe weather warnings are in force for some of the worst hit areas. Yellow National Severe Weather warnings for rain have been issued for southern and north west Wales on Wednesday evening and through Thursday.
Chief Meteorologist Andy Page said: “Further rain will arrive on Wednesday evening and this is likely to become prolonged and possibly heavy over areas of high ground. For example, there is a chance that 60mm of rain could fall in parts of south Wales over 24 hours. With the ground already saturated there is a chance of further flooding, members of the public should check their flood risk and stay up to date with flood warnings from Natural Resources Wales, SEPA, NI Direct and the Environment Agency.”
Blustery showers will continue through the day on Monday and Tuesday, particularly in the west, these showers are likely to fall as snow over higher ground especially in Scotland over 200m in elevation. Although there will be sunny spells for many, thunder and hail could accompany the heavier showers.
Under clear skies on Tuesday night pockets of frost are likely as more settled conditions associated with a brief ridge of higher pressure pass through.
Rain and increasingly strong winds will move in from the west on Wednesday morning spreading across the whole of the UK through the day. Rain will be persistent and heavy at times in Wales and north western England overnight and a further front will move through on Thursday bringing heavy downpours.
Storm Dennis brought wet and windy conditions after what was an unsettled week, with Storm Ciara bringing stormy conditions the weekend before. South Wales saw the most rain from Storm Dennis, with 157.6mm recorded at a Natural Resources Wales site in Crai Resr, Powys, between midnight on Saturday morning to 10:00 this morning (17 February). The highest wind speed recorded during the storm was 91mph on Saturday evening at Aberdaron, Gwynedd.
