Met Office Issues Yellow Warning as Heavy Rain and Gales Hit Cornwall

The Met Office has issued a Yellow weather warning for rain across Cornwall from 12pm to 11:59pm today (Tuesday 11th November).

Heavy rain, accompanied by strong southerly winds, is expected to cause difficult driving conditions and could lead to flooding in places.

What to Expect

The Met Office says flooding of a few homes and businesses is possible. Bus and train services are likely to be affected, with longer journey times expected. Spray and flooding on roads could also make travel more difficult, especially during the evening commute.

Further Detail

Rain will move in from the west during Tuesday morning and become heavier and more persistent through the afternoon. Southerly winds will strengthen, with gales developing in places.

Rainfall totals of 20–40mm are likely fairly widely, with 50–70mm possible in the wettest spots, particularly on south-facing slopes of the moors. The Met Office added that rainfall may continue into Wednesday, although details beyond tonight are uncertain.

Given recent wet weather and already saturated ground, flooding could occur in a few areas. Drivers are warned of difficult conditions and potential delays due to slow traffic and the increased risk of collisions.

What Should I Do?

Residents are advised to check whether their property is at risk of flooding and, if so, prepare a flood plan and emergency flood kit.

Travellers should check road conditions and public transport timetables before setting out, and consider amending their plans if necessary.

The Met Office also recommends being prepared for possible power cuts, suggesting that people gather torches, batteries, a mobile phone power pack, and other essential items in advance.

People are urged to stay up to date with the latest Met Office weather forecast, as warnings can change quickly.

Why is the Warning Yellow?

This alert carries a medium likelihood and a low impact, meaning some disruption is expected but widespread damage is unlikely.
