Blackwood, Wales, United Kingdom Severe Weather Alertstar_ratehome

Outbreaks of rain arriving from the west during Tuesday morning will become heavy and persistent at times, especially but not exclusively over south facing hills, and accompanied by increasingly strong southerly winds.

30-50 mm of rain is likely fairly widely, with 60-80 mm of rain building up in the wettest spots over south facing hills. Much of this could come in heavy bursts during Tuesday afternoon and early evening. Although likely fading fairly by late Tuesday night, rainfall could resume early Wednesday, although details become increasingly low confidence. This warning may be extended tomorrow or a fresh warning issued for Wednesday morning should confidence in a wetter scenario increase.

Given recent wet weather, and saturated ground in places, this could lead to some flooding in places. Difficult travelling conditions for the evening commute are also expected, with delays and the increased possibility of accidents.
