Heavy Rain Warning Issued: Could Your Area Be at Risk of Flooding?

A yellow weather warning for rain has been issued across parts of western Britain, including Cornwall, from midday today (Tuesday 15th April) until midday tomorrow (Wednesday 16th April).

The Met Office has warned that heavy and persistent rainfall could lead to localised flooding, transport delays, and possible power interruptions as the unsettled weather moves north through Tuesday and into early Wednesday.

What to Expect

The warning includes the possibility of:

Flooding of a few homes and businesses
Spray and flooding on roads, likely causing longer journey times
Disruption to bus and train services
A chance of power cuts and interruptions to other services

According to the Met Office, 20–40mm of rain is expected fairly widely, with some locations potentially seeing 50–75mm. In the west, rainfall will build gradually following showers on Monday, while the east may experience heavy downpours and slow-moving thunderstorms in a shorter timeframe.

How to Prepare

Residents are urged to check if their properties are at risk of flooding, and consider creating a flood plan and assembling an emergency flood kit.

Drivers are advised to check road conditions and travel updates before setting off, as journey times may be longer. Those using public transport should keep an eye on bus and train timetables and adjust travel plans if needed.

To prepare for potential power outages, the Met Office recommends having torches, batteries, and a mobile phone power pack ready, along with other essentials.

Stay Updated

The Met Office stresses that weather warnings can change quickly and advises the public to keep up to date with the latest forecast for their area.

Why A Yellow Weather Warning?

This yellow warning signifies a medium likelihood of impacts and a low overall level of impact—but those in affected areas are still encouraged to be cautious and stay prepared.
