The Met Office provides automatic data feeds to BBC Weather, 24 hours a day and 365 days a year.

We provide forecast data for approximately 4000 locations around the world including a 24 hour forecast for over 300 locations in the UK. We also provide graphical forecasts on maps for all around the world.

This is produced automatically by the Met Office's NEC SX-6/8 super computer, with quality control of the graphical forecasts and some UK location forecasts carried out at the Met Office Operations Centre.

The locations forecasts are received from the Met Office twice a day at 07:30 and 19:30 GMT. Once processed by BBC servers these files are uploaded to the 5-day forecasts online, Red Button and BBC Mobile services.

The forecast information you see on maps is updated four times a day (forecast for the next two days) in the UK or twice a day (days 3-5 in the UK and all five days for non-UK locations).

Further quality control of the data can be carried out by the Duty Forecaster at BBC Weather Centre. Any changes made are sent to all of our outputs every half-hour, so the data you see on the website is the same as that you see on TV.

If you have any comments or views on the data supplied by the Met Office you can find contact details on the Met Office feedback page.
