27/09/2024 – Weather in Cornwall – Yellow Weather Warning For Rain

Published On: 27 September 2024Last Updated: 27 September 2024By CornishStuff

The Met Office has issued a yellow weather warning for rain, effective from 6 am today until 9 am today. The warning highlights the potential for flooding and transport disruptions as heavy rain and thunderstorms are expected to hit parts of Wales and central and eastern England.

What to Expect

The Met Office warns that some areas could experience significant rainfall, with the potential for 10-15 mm of rain within an hour. A few locations may see up to 30 mm of rainfall over several hours during the day. This could increase to 20-30 mm in 2-3 hours and potentially 40-60 mm in 3-6 hours during Thursday evening and early Friday morning. Given the recent wet weather, this could lead to further flooding and disruptions.

There is a small chance that homes and businesses could be flooded, causing damage to buildings. Flooding could also result in delays or cancellations to train and bus services, and difficult driving conditions with the possibility of road closures. Some communities might become temporarily cut off due to flooded roads.

The Met Office has also noted a slight chance of power cuts and the loss of other essential services to some homes and businesses. In extreme cases, fast-flowing or deep floodwater could pose a danger to life.

How to Stay Safe

Check if your property is at risk: If your home or business is in a flood-prone area, consider preparing a flood plan and an emergency flood kit.

Plan your travel: Check road conditions, bus, and train timetables before setting out. Be prepared to change your travel plans if necessary to avoid affected areas.

Prepare for power cuts: Ensure you have torches, batteries, a mobile phone power pack, and other essential items ready. It’s always best to be prepared in advance.

Stay updated: Weather warnings can change quickly. The Met Office recommends staying up to date with the latest weather forecast.

Why a Yellow Warning?

The yellow warning signifies a very low likelihood of medium impact. While not all areas will experience the worst of the weather, the conditions are unpredictable. The Met Office updated the warning this morning to reflect the earlier start time due to the expectation of heavy showers and thunderstorms throughout the day.
