Thunderstorms and heavy rain may cause travel disruption across parts of southern England and Wales, the Met Office has said.
A yellow thunderstorm warning has been issued by the weather service from 4pm to 11.59pm on Monday for much of south Wales, south-west England and parts of southern England.
They had forecasted a high possibility that the driving conditions will be impaired by spray, standing water or hail, and one could expect delays in rail services.
There is also the possibility of flooding of some dwellings and commercial buildings, with the chances of damage by lightning strikes, hail, or gusty winds as these can expect to be relatively close to coasts.
According to Frank Saunders of the Met Office who is a chief meteorologist, “Areas of heavy showers and thunderstorms will move northwards across southern parts of England and Wales later this afternoon before clearing northwards overnight.
“That possibility does exist that some places could see 20-30mm of rain within two to three hours, with a small chance that a few places could receive 40mm”.
“Thunderstorms are most likely for south-facing coastal districts, and hail and some strong gusts of wind could accompany the heaviest showers and thunderstorms.
More heavy showers and thunderstorms are expected on Tuesday for central and southern parts of the UK.
A longer spell of heavy rain was forecast over parts of south-east Scotland and north-east England later on Tuesday through to Wednesday.
Further weather warnings are possible up until mid-week as rain falls on already saturated ground, the Met Office said, but added that the risk of flooding should reduce.
The weather service added that it also had increasing confidence that ex-Hurricane Kirk would track to the south of the UK and bring heavy rains and strong winds to northern France.
Although north and south movements were still possible, the potential for impacts of significance to the UK from the ex-hurricane are much reduced, it added.
Temperatures would start to fall from Wednesday in the north, and all parts were expected to see below average temperatures from Thursday onwards, the Met Office said.
Night frosts are also possible over some areas later in the week, while snow is possible over the higher mountains of Scotland.
Wales will shortly face heavy downpour as the Met Office has issued weather warnings concerning widespread flooding in low-lying areas and other regions close to rivers and coastlines.
They should prepare for any disruption, which may include localized flooding, travel delays, and challenging driving conditions due to waterlogged roads. Those staying in vulnerable flood areas should monitor weather alerts and be prepared to take action to secure sandbags where necessary, outdoor belongings, etc.
With the rains, there are also thunderstorms. Some areas could have a power outage. Authorities would like people to stay indoors when the rains get intense and refrain from non-essential traveling until it gets better.
Heavy rain and storm across Wales continue; residents should be monitored closely through local weather reports and advice from the emergency services so one is safe.
