The Met Office has issued an updated Yellow rain alert for London and South East England as well as South West England for Monday and Tuesday. All local areas affected are listed below.

Intense showers will batter the regions. The rainfall is projected to arrive across the areas on Monday at around 6pm, and it will last until Tuesday 9pm.

The updated Yellow warning for rain was issued at 10:03am on Monday, February 2.

A Met Office forecast said: “Outbreaks of rain are expected to become persistent later on Monday, especially overnight, before gradually clearing during Tuesday, perhaps not clearing the northeast of the warning area til Tuesday evening. Accumulations of 10-20 mm are possible fairly widely, with perhaps as much as 40-60 mm over Dartmoor. Given saturated ground following recent rain, there is a chance this may leading to some flooding and disruption in places.”

There is a small chance that homes and businesses could be flooded, causing damage to some buildings; There is a small chance of fast flowing or deep floodwater causing danger to life; Where flooding occurs, there is a slight chance of delays or cancellations to train and bus services; Spray and flooding could lead to difficult driving conditions and some road closures; There is a small chance that some communities will become cut off by flooded roads; There is a slight chance of power cuts and loss of other services to some homes and businesses.

What should you do during heavy rain?

Check if your property could be at risk of flooding. If so, consider preparing a flood plan and an emergency flood kit.

Give yourself the best chance of avoiding delays by checking road conditions if driving, or bus and train timetables, amending your travel plans if necessary.

People cope better with power cuts when they have prepared for them in advance. It’s easy to do: consider gathering torches and batteries, a mobile phone power pack and other essential items.

What is an updated yellow weather warning?

The Met Office has three categories of weather warning, depending on the likely impact of severe weather and also how likely it is to strike in a particular area.

A yellow warning is issued when weather conditions are expected to disrupt travel and traffic and may impact on daily routines but are not likely to pose a risk to life or property.

An amber warning is more severe and advises people to think about changing their plans to minimise the risk.

A red warning means weather conditions are expected to be dangerous with widespread damage to property and a risk to life, with the public usually advised to avoid travelling.

The Yellow weather alert for rain will remain in effect until 9pm on Tuesday.
