About the Met Office Weather Warnings

BBC Weather carries two types of weather warnings issued by the Met Office: Warnings and Early Warnings.

Warnings will be issued when severe weather is expected within the next 24 hours.

Early Warnings will be issued more than 24 hours ahead of severe weather.

There are three categories of event Red, Amber and Yellow - the most severe is Red.

A Warning and an Early Warning of the same colour have the same severity but are forecast to arrive at different times. Thus, the difference between a Red Warning and a Red Early Warning is the lead time of the event.

When a warning is in force, full information can be found at Met Office Weather Warnings

About Flood Warnings

The flood warnings are issued by the Environment Agency, the Scottish Environment Protection Agency and Natural Resources Wales, and sent to the BBC Weather Centre. We then issue a compendium of warnings based on the latest information available. When severe flood warnings are issued they will also be highlighted on TV broadcasts.

Find out more about Flood Warnings

There are a number of ways you find out whether your area is at risk from flooding. The Environment Agency, the Scottish Environment Protection Agency and Natural Resources Wales update their warnings 24 hours a day via the Floodline number.

Monthly Outlook

Summary
Cool May continues, but will June be flaming?

After a somewhat cool and changeable spell of weather, there are signs as we head into a new month that the Azores high - a semi-permanent area of high pressure located over or near the Azores islands in the Atlantic - might start to dominate the weather a little more frequently. This should help lift temperatures back closer to average, or even a little above at times, especially in more southern parts of the UK. Before that though, this week will be showery, still on the cool side for the time of year, and often breezy. In the strong spring sunshine between showers it will feel rather pleasant, but clear skies and light winds after dark will allow chilly nights.

Monday 18 May—Sunday 24 May
Rough winds do shake the darling buds of May

On Monday, following a wet start in the south and east of the UK thanks to a lively cold front, brighter conditions are following from the northwest for the rest of the day. However there are also scattered and increasingly blustery showers, some of these heavy and thundery in the north of the country. Tuesday and Wednesday will also be breezy, especially in western and southern parts. Sunshine and showers sums up these two days, though as is the nature of such convective weather days, some places will see more showers than sunshine, and other places will see more sunshine than showers. Where the showers do fall, they will again have the potential to be heavy and thundery.

High pressure moves in from the southwest on Wednesday night to settle things down for Thursday, but with weather fronts never too far away. On Thursday these will act to keep it cloudier in the north of the UK with rain at times. Friday is expected to remain cool, cloudy and breezy with some rain in the north and west, whilst southeastern parts should enjoy drier, brighter and somewhat warmer weather with temperatures here returning to nearer average for late May.

With higher pressure extending from the Azores this will tend to favour the south for a largely dry, bright and slightly warmer weekend. As weather fronts steer around the top of the high towards the north of the country, it will be comparatively cooler, breezier and showery here over the weekend.

Monday 25 May—Sunday 31 May
Ne'er cast a clout...

For the last full week of May no dramatic change in weather type is expected. With the Azores high steering low pressures from the north of the North Atlantic towards Scandinavia or the Low Countries, this tends to favour cooler westerly or northwesterly winds across the UK. So the rather cool and changeable theme is likely to continue through to the end of the month, with a mix of sunshine and occasional rain. The rain will be most prevalent in the north, nearer to the passage of low pressure centres, where it is likely to be breezy at times. In the south, nearer to the influence of the Azores high, dry and bright weather is more likely to dominate, however the high pressure's dominance may still wane enough to allow rain or showers further south across the country. Temperatures will range from below normal in the north to about average in the south.

Monday 1 June—Sunday 21 June
Shall I compare thee to a summer's day?

Although the first week of June looks like carrying on the themes of May, there are hints that high pressure might dominate the weather more often than not as the new month progresses. If so, we might expect a good deal of dry, warm and settled weather, particularly - as models suggest - across southern and eastern areas. Frontal systems are still likely to make inroads from the Atlantic at times, though most of the rain associated with these is likely to affect north-western areas. If high pressure does take more of a hold across the UK, temperatures should range from near normal in the north, to just above average in the south. Which means we should see a few more days with temperatures in the high teens to low twenties Celsius than we have done of late. And, as we head into the season of summer, I am sure that will be welcomed by many.

Next week

With summer finally here climatologically and astronomically, and some popular outdoor events looming, will the weather play ball?

Monthly forecasting
The weather beyond about a week ahead stretches even the most experienced weather forecaster. Complex numerical weather forecast models from the Met Office and the European Centre for Medium-Range Weather Forecasts (ECMWF) are run many times for the month (and season) ahead to build up a picture of the likelihood of different weather types affecting the UK.
