03/02/2026 – Weather in Cornwall – Yellow Weather Warning For Rain

Flooding Risk Grows as Heavy Rain Hits Tonight

A yellow weather warning for rain has been issued by the Met Office, covering the period from 6pm on Monday 2nd February through to 9pm today, Tuesday 3rd February.

Further rainfall through Monday evening and into Tuesday could lead to some flooding and disruption in places, particularly as ground conditions are already saturated following recent rain.

What could happen

The Met Office says there is a small chance that homes and businesses could be flooded, which may cause damage to some buildings. There is also a small chance of fast flowing or deep floodwater posing a danger to life.

Where flooding occurs, there is a slight chance of delays or cancellations to train and bus services. Spray and standing water could make driving conditions difficult, with some road closures possible. In some areas, flooded roads could leave communities cut off.

There is also a slight chance of power cuts and the loss of other services affecting some homes and businesses.

Rainfall outlook

Outbreaks of rain are expected to become more persistent later on Monday, especially overnight, before gradually clearing during Tuesday. Some areas, particularly the north east of the warning zone, may not see conditions improve until Tuesday evening.

Rainfall totals of 10 to 20mm are possible across a wide area, with higher totals of 40 to 60mm over Dartmoor. With the ground already saturated, this increases the risk of flooding and disruption.

What people are advised to do

People are advised to check whether their property is at risk of flooding and, if so, consider preparing a flood plan and an emergency flood kit.

Drivers are encouraged to check road conditions before travelling, while those using public transport should keep an eye on bus and train timetables and adjust travel plans if needed.

The Met Office also advises preparing for possible power cuts by having torches, spare batteries, a mobile phone power pack and other essential items ready.

Weather warnings can change quickly, and people are advised to stay up to date with the latest local forecast.

Why the warning is yellow

The yellow warning reflects a very low likelihood of impacts, but with the potential for medium disruption where flooding does occur.
