Met Office Weather Warnings – Live Map & Severity Guide

The Met Office issues weather warnings across the UK to inform the public and emergency services about potentially hazardous conditions. These warnings, updated at least every six hours, cover rain, snow, wind, ice, thunderstorms, lightning, extreme heat and fog up to seven days ahead. Understanding what each warning colour means — and where to find the live map — helps people plan their day and stay safe.

What Are the Met Office Weather Warnings Today and Tomorrow?

For the most current warnings, the national UK weather page provides a seven-day forecast alongside an interactive map showing active and upcoming warning areas. The Met Office issues warnings for the whole of the UK, including England, Scotland, Wales and Northern Ireland.

When checking for today and tomorrow, users should look at the coloured polygons on the map and read the accompanying warning text. A yellow warning may cover a large area and indicate low-level impacts, while an amber or red warning signals more severe conditions with a higher likelihood of disruption.

Key insights at a glance

• Warnings are updated at least every six hours, sometimes more frequently during active severe weather.
• Yellow warnings account for roughly 70 percent of all warnings issued by the Met Office.
• Amber and red warnings are reserved for situations where there is a risk to life or significant damage to property.
• The official Met Office warnings map is the most reliable real-time source; third-party apps may introduce delays.
• Each warning colour is determined by a combination of impact and likelihood, not by weather type alone.
• The same colour system applies to rain, snow, wind and all other weather hazards.

Where Can I Find the Latest Met Office Weather Warnings Map?

The Met Office weather warnings guide explains that the live map is embedded on the official warnings page. It displays current and forecast warning areas as coloured overlays on a map of the UK, with each colour corresponding to the severity level.

Users can zoom into specific regions, click on individual warning polygons, and read the detailed text that accompanies each alert. The text includes the expected weather type, the time period the warning covers, and the likely impacts.

How to check warnings live

The most direct way is to visit the official UK weather warnings page on the Met Office website. The page loads with an interactive map that is mobile-responsive and can be used on smartphones and tablets. No app download is required, though the Met Office does offer a dedicated app with push notifications.

Which UK regions are currently covered

Warnings are issued for all parts of the UK. On any given day, some regions may have no active warning while others may be under yellow, amber or red alerts. The map updates automatically as new warnings are issued or existing ones expire. For seasonal advice and the reasoning behind warnings, the Met Office provides dedicated guidance pages.

What Is the Met Office Weather Warning for London and Nearby Areas?

London and the surrounding areas, including the Home Counties, are subject to the same warning system as the rest of the UK. When a warning is active for London, it appears as a coloured polygon on the national map. The Met Office national forecast page includes local forecasts that cross-reference with any active warnings.

Are there any warnings near London right now

Because warnings change frequently, the most reliable way to check for London-specific alerts is to consult the live map and filter by region. The map allows users to click on the Greater London area to see whether any warnings are in force and what the expected impacts are.

How local forecasts relate to warnings

The Met Office provides local forecast pages for cities including London, which show the day-by-day outlook. If a warning is active, the forecast page usually includes a banner or link directing users to the warning text. For London, the local page also includes hourly breakdowns and a seven-day view.

What Does a Met Office Yellow, Amber, or Red Weather Warning Mean?

The Met Office uses a three-colour system — yellow, amber and red — to communicate the severity of expected weather. The colour is determined by a combination of the impact the weather is likely to have and the likelihood of that impact occurring, as explained in press reporting on the system.

Yellow warning: be aware

A yellow warning means weather is likely to cause some low-level impacts and possible travel disruption in places, though many people may continue their usual routine. The Met Office also uses yellow for situations where impacts could be more severe but confidence in the forecast is lower, so reading the warning text carefully is essential.

Amber warning: be prepared

An amber warning indicates an increased likelihood of severe-weather impacts that could disrupt plans. Travel delays, road and rail closures, power cuts, and risk to life and property are possible. People should consider changing plans and taking action to protect themselves and their property.

Red warning: take action now

A red warning means dangerous weather is expected. The Met Office advises that people should take action immediately, avoid travelling where possible, and follow advice from emergency services and local authorities. Risk to life is very likely, with major disruption to travel, energy supplies and possible widespread damage.

Does the Met Office issue warnings for thunderstorms and lightning

Yes. Thunderstorms and lightning are among the weather types covered by the warning system. The same yellow, amber and red colour scale applies. A yellow thunderstorm warning, for example, might mean isolated disruption from lightning and heavy rain, while an amber warning could indicate more widespread storms with a higher chance of flooding and damage.

How Long Do Met Office Weather Warnings Typically Last?

Warnings are issued with a specific start and end time. They can last from a few hours to several days, depending on the weather system. The Met Office provides warnings up to seven days ahead, though confidence decreases further into the forecast period.

Notable warnings from the past 12 months illustrate the range of durations and impacts:

1. March 2025: Storm Nelson brought a red wind warning for Cornwall, with gusts posing a danger to life.
2. January 2025: Snow and ice warnings covered much of Scotland, with amber alerts for several days.
3. November 2024: Storm Bert triggered widespread flooding warnings, including amber rain alerts across northern England and Wales.
4. July 2024: An amber heat-health alert was issued alongside Met Office warnings for extreme heat in parts of southern and central England.

How Certain Are Met Office Weather Warnings?

The Met Office issues a warning when a severe weather event is considered likely, meaning the probability is greater than 60 percent. A red warning is only issued when confidence is very high, typically above 80 percent. This distinction matters when deciding how to respond.

How Does the Met Office Decide to Issue a Weather Warning?

The Met Office uses an impact-based warning system that was introduced in 2011. This replaced the older purely likelihood-based approach. The system evaluates both the chance of a weather event occurring and the potential consequences for people, property and infrastructure.

Forecasters draw on data from computer models, weather radar stations, satellite imagery and local observations. They also collaborate with other agencies such as the Environment Agency and Natural Resources Wales to ensure consistency in flood warnings and severe weather alerts. The goal is to give the public enough time to prepare without causing unnecessary alarm.

As the Netweather explanation of the system notes, the colour is based on a combination of impact and likelihood, not on the type of weather alone. This means a yellow warning for snow can mean very different things from a yellow warning for rain or wind.

Where Can I Find Reliable Information About Met Office Weather Warnings?

The most authoritative source is the Official Met Office UK Weather Warnings page. This is the government-mandated source for all severe weather alerts in the UK. Additional guidance is available from UK Government Weather Warnings Guidance.

For road travel, National Highways Travel Updates provide real-time information about road closures and conditions during severe weather.

What Should I Do When a Met Office Warning Is Issued?

The recommended action depends on the warning colour. For yellow warnings, stay aware of the forecast and allow extra time for travel. For amber warnings, prepare for disruption, check travel plans, and secure your property. For red warnings, take immediate action to protect yourself and others, avoid travel, and follow instructions from emergency services.
