UK weather warnings: understand the risk and act
A weather warning helps you decide what to change before severe weather affects you. Start with the Met Office warning for your location, then check the times, expected impacts and recommended action. Consider your journey and the people you support as well as your home. This guide explains the services; use their own pages for current conditions.

Read the detail behind the colour
Met Office warnings cover the UK. Their colour combines the likely impact with the likelihood of that impact happening. A yellow warning can still describe serious disruption with lower certainty. Open the full warning rather than relying on a headline or a shared screenshot.
| Colour | What it can mean | Your next action |
|---|---|---|
| Yellow | Disruption is possible. The scale and certainty vary between warnings. | Read the expected impacts and check whether your plans or circumstances make you vulnerable. |
| Amber | More likely disruptive impacts, potentially including power cuts, closures and danger to life. | Consider changing plans and complete preparations before conditions worsen. |
| Red | Dangerous weather with a very high likelihood of risk to life and substantial disruption. | Act now to protect yourself. Avoid travel where possible and follow instructions from emergency services and the responsible provider. |
Check the place, time and practical consequences
- Open the affected-area map and check the start and end times, including overnight periods.
- Read the expected impacts and action advice for your home, destination and route.
- Check transport operators, schools or care providers directly if disruption would affect your arrangements.
- Return to the Met Office warning before setting off. Warnings can change as the forecast develops.
Use the right flood service
A rain warning and a flood warning answer different questions. Check the flood authority as well as the weather forecast. England, Wales and Scotland provide flood warning services. Northern Ireland's nidirect page explains flood risk information and links to relevant advice; its maps are not a live flood warning feed.

Know which other alerts apply
UKHSA Heat-Health and Cold-Health Alerts describe likely health impacts in England. They are separate from UK-wide Met Office warnings. Use health advice and local updates relevant to your nation.
Government Emergency Alerts may warn compatible phones about a nearby danger to life. They do not replace checking forecasts, local news or specialist warnings.
Your warning checklist
- Choose how you will receive Met Office updates and bookmark the Met Office warning page.
- Charge your phone and arrange another source of information if mobile service fails.
- Agree who will check on anyone who needs help, and when.
- Choose the relevant preparation guide and complete its urgent tasks while conditions are safe.
Turn a warning into decisions for your household
Do these checks when you first see a relevant warning, again before travel or a care handover, and whenever the Met Office advice changes. Prepare Now explains how to use warnings; it does not display a live warning feed.
| Check | Decide | Record |
|---|---|---|
| Place and time | Are home, work, school, a care visit or the whole journey affected? | The Met Office warning link and next time to recheck it. |
| Likely impacts | Could power, heating, deliveries or travel be interrupted? | Which supplies, appointments and backup arrangements need attention. |
| People | Who needs contact before phone or travel disruption starts? | An agreed check-in time and what happens if it is missed. |
| Action advice | What do the warning and local services tell you to change? | Who will change the journey, collect supplies or contact the provider. |

Common questions
Does a yellow warning mean it is safe to travel?
It is not a travel guarantee. Read the impacts for your route, check your transport operator and consider whether you can postpone a journey that would expose you to the hazard.
Will every weather warning trigger an Emergency Alert?
No. They are separate systems. Check the Met Office and national flood services yourself and follow local instructions whether or not your phone sounds.
