The Met Office has issued a yellow weather warning for rain in parts of Wales. The forecaster has warned that heavy showers, perhaps thundery at times, are possible in places on Wednesday night and into Thursday morning. The warning is in place from 9pm on Wednesday, September 4 until 9am on Thursday, September 5.
According to the Met Office, areas could see an accumulation of 20-40mm of rainfall in a couple of hours, while there’s a small chance that other areas could see up to 50mm of rainfall. The affected areas include Blaenau Gwent, Bridgend, Caerphilly, Cardiff, Merthyr Tydfil, Monmouthshire, Newport, Rhondda Cynon Taf, Torfaen, and the Vale of Glamorgan.
The warning reads: “Whilst there is some uncertainty, and not all areas will be affected, scattered heavy showers on Wednesday evening may merge into longer spells of heavy, showery rain in places through Wednesday night into Thursday morning. Where heavy downpours occur, perhaps thundery in places, accumulations of 20-40 mm are possible in an hour or two, with the small chance of isolated accumulations over 50 mm, potentially impacting the Thursday morning commute in some areas.”
This weather warning follows a previous alert for heavy rain and thunderstorms issued for Wales on Monday, September 2. The forecaster had warned that thunderstorms could cause flooding and disruption in places with flood alerts issued for some areas of Wales.
The warning has also been extended to regions in the east Midlands, east of England, London, and south east England, as well as large parts of south Wales. Subscribers can receive the latest Welsh news delivered to their inbox by signing up for the newsletter on the WalesOnline website.
