Met Office issues new thunderstorm warning for parts of Wales

The Met Office has issued a new thunderstorm warning for parts of Wales, according to Wales Online. The warning covers areas in south east Wales, including Monmouthshire, Newport, and Torfaen. The forecast indicates showers and thunderstorms moving north and east across southern Britain throughout the afternoon and evening, gradually clearing from the west.

This announcement marks the second consecutive day of thunderstorm warnings for parts of Wales as a series of low-pressure systems bring unsettled weather to the region. The warning, in place until 3am on Wednesday, highlights the potential for heavy rainfall, hail, and lightning. Some areas might experience 20-30 mm of rain within 2-3 hours, with a small chance of 40-50 mm over a longer period, particularly in the southeast of the area in the evening. Hail and lightning are additional hazards, with possible temporary hail accumulations and gusty winds up to 40 mph in some areas.

The Met Office’s forecast for Wales on Wednesday anticipates a day of “sunshine and showers” with lighter showers compared to Tuesday. Looking ahead, Thursday is expected to be drier with a few showers in the west, while Friday is likely to be largely fine with sunshine, and further showers into Saturday. Temperatures are set to drop, with patchy fog and frost potential overnight.

The warning advises that spray and sudden flooding may lead to challenging driving conditions, potential road closures, and isolated communities cut off by flooded roads. In areas affected by flooding or lightning strikes, there could be delays and cancellations in train and bus services, as well as a slight chance of power cuts impacting homes and businesses. Buildings may also sustain damage from floodwater, lightning strikes, hail, or strong winds.

The Met Office’s announcement serves as a reminder for residents in the warned areas to stay informed about the weather conditions and take necessary precautions to ensure their safety during the upcoming thunderstorms.
