About the Met Office Weather Warnings

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

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

Alerts 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 Alert 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 Alert 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
Where has summer gone?

It's gone south, pushed away from our shores by a strong and cool northerly wind. That wind has dropped the temperatures and brought quite a lot of showers with it, some heavy and thundery. Looks like there's more of the same over the next week but it won't be raining all day everywhere and as the winds ease and given there will be some sunshine, it should still feel pleasant enough especially so in the south.

Monday 18 August—Sunday 24 August
Generally unsettled and cooler than average

Temperatures and the general feel of the weather will be a talking point early in the week because it will be windy and cool with plenty of showers but also some drier, brighter spells. The brisk winds will gradually ease as the low pressure centre that's driving our weather eases away towards Scandinavia.

The distribution of the showers will change daily, eastern England will be a focal point on Monday and Wednesday, probably that bit drier on Tuesday.

By Thursday, some uncertainty creeps into the forecast as an area of more general rain spreads down from the north with showers following. The southeast will probably stay dry whilst on Friday it looks like showers could develop widely across the UK. Rainfall amounts are likely to be around average for most but in the north and east of the UK it will probably be quite wet.

Temperatures will be below or even well below normal especially in the north, accentuated by the winds early in the period. Nights will be relatively chilly with some rural spots dipping well into single figures.

As the bulk of the rain this week will be from showers there should be some sunshine around too, some western parts doing quite well with at least average amounts of sunshine.

The Bank Holiday weekend may well start on a mostly dry note but cloud and rain is gathering out west.

Monday 25 August—Sunday 31 August
A change in the winds...

Not a change to a warm southerly and a return to summer but more of a westerly weather pattern is likely to develop. That will bring low pressure systems and their associated fronts from the Atlantic.

So, for the last week of the summer holidays the unsettled theme continues but at least we should see temperatures recovering to something closer to the norm for the time of year.

With Atlantic lows crossing the UK there's likely to be a lot of cloud and rain this week. Consequently, we aren't going to see a great deal of sunshine, and the rain could be quite heavy with above or well above average amounts expected. The south east probably seeing a bit less rain than elsewhere but confidence on this aspect is relatively low.

Monday 1 September—Sunday 14 September
Pressure risng in the south?

Back to school and we keep the west or northwesterly winds so most of the rain this week will be in the north and west of the UK.

Nowhere is likely to see above normal rainfall amounts but it should be drier in the south and east. Pressure may well rise in the south, helping to keep things mostly dry with some sunshine at times. However, with the northwesterly winds we'll be dragging in some cooler air so temperatures will be a bit on the low side both by day and night.

The details at this range are difficult but we are fairly confident that the west or northwest winds will be with us.

Next week

September is a transitional month - which way will the last two weeks go?Could we see a return to something more summery?

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.
