rivers have been urged to take care after predictions of flash flooding are expected due to the yellow weather warning.
There is a flood alert across six London areas covering Beverley Brook, Ravnsbourne, River Hogsmill, River Rythe, River Wandle, and Shuttle and Cray.
Further power cuts, delays, and train and bus cancellations are predicted, while spray and sudden flooding could lead to difficult driving conditions for motorists.
However, Britain is still undergoing a drought due to below-average rainfall for the month, according to the Met Office.
Thunder, lightning, and flooding have affected the United Kingdom after a yellow weather warning came into force across the United Kingdom.
The Met Office implemented the warning for Scotland and Northern Ireland on Monday, August 22, and from Tuesday across England and Wales, after a change in air pressure led to dramatic showers.
Greg Dewhurst, a meteorologist at the Met Office, told the PA news agency that Thursday “is the last day where we’ll see temperatures above 30°C for the rest of the week”.
The Met Office added that Thursday will see “heavy, thundery rain affecting the south-east and East Anglia, easing through the day.”
“Friday will also be unsettled, with cloud and outbreaks of rain affecting many western parts, replaced by showers in the afternoon. Elsewhere, it will be mostly dry and fine.”
The bank holiday weekend should be relatively settled, with a little “patchy rain at times into the far north-west, elsewhere mostly fine, with just an odd isolated light shower, and plenty of warm, sunny breaks”.
Here’s everything you need to know about yellow thunderstorm warnings.
What is a yellow thunderstorm warning?
According to meteorologist Siobhan Ryan: “A status yellow weather alert is given to warn those at risk from certain weather because of their location and/or their activity. It advises these people to take preventative action. Expected weather conditions in a status yellow alert do not pose an immediate risk to the general population.”
According to the Met Office, yellow weather warnings suggest people should “be aware”. On the Met Office website, it outlines a yellow weather warning will be issued when the weather will cause “low-level impacts, including some disruption to travel in a few places”.
It adds: “Many people may be able to continue with their daily routine, but there will be some that will be directly impacted and so it is important to assess if you could be affected.
“Other yellow warnings are issued when the weather could bring much more severe impacts to the majority of people but the certainty of those impacts occurring is much lower.
“It is important to read the content of yellow warnings to determine which weather situation is being covered by the yellow warning.”
What can be expected from a yellow thunderstorm warning?
In terms of what to expect, the Met Office has said:
- Spray and flooding could lead to difficult driving conditions and road closures
- A chance that homes and businesses could be flooded quickly, with damage to some buildings from floodwater, lightning strikes, hail or strong winds
- A slight chance that power cuts could occur and other services to some homes and businesses could be lost
- A small chance of fast flowing or deep floodwater
- Where flooding or lightning strikes occur, there is a chance of delays and some cancellations to train and bus services
