Below are some of the commonly asked questions about BBC Weather.
The towns and cities on the map are only there to help give viewers their bearings. If we put more town names on it would obscure the weather information.
Daily weather symbol: The daily symbol shows the most representative weather type for the whole day, or whole night, at that location. This could either be the predominant weather - that is, the weather that lasts for the longest period of time - or alternatively, the most significant weather.
So if a day is forecast to be mostly sunny with the possibility of a brief shower, then we are likely to see a sunny symbol rather than shower symbol. However, a thunderstorm symbol may appear if a thunderstorm is expected in an otherwise largely dry day. For the purposes of the forecast the day covers the period from 0600 to 1800 GMT and the night from 1800 to 0600 GMT on the following day.
Hourly/three-hourly weather symbol: The symbol that appears for each hourly or three-hourly timestep indicates the weather expected at or near the relevant location, around the time indicated. For example if a shower symbol appears for Exeter at 1500, we are saying there is a chance of a shower in the Exeter area at or close to 1500. There could be one a short distance away and it may actually occur at 1430.
However, there can be discrepancies seen between the maximum/minimum temperature given for the daily summary and the highest and lowest temperatures seen in the hourly breakdown. This is because the hourly value is given for "on the hour" whereas the max/min may occur between the hourly points so may be slightly higher/lower.
Maps: The weather maps are produced using Met Office data once every six hours whereas the text-based data refreshes on an hourly basis, meaning the map data can often lag behind the 24-hour and five-day forecast.
While we use the same data source across TV, radio, online and the app, the forecasts can differ slightly due to the frequency at which this data is updated, as well as the granularity of the location information.
For example, a TV or radio broadcast you see at 1pm will be prepared using the latest data we have up to that point. If you check the forecast at 2pm on the website, we may have since received an updated set of data, and as such, the forecast available online could have changed from the one you saw earlier on TV.
Similarly, the forecast for a typical UK location on the website is updated every hour. Depending on the frequency settings you have configured in the Settings menu of the app, weather information in the widget could be anything up to 12 hours behind, although you will always see a message informing you when the app last refreshed its feed. You can also manually refresh the data by tapping the refresh icon.
While we always aim to provide an accurate and consistent forecast, we choose to provide you with the most up-to-date and accurate information as soon as we receive it.
When the forecast predicts gusts of wind over 40mph, the hourly wind icon - which usually shows the sustained wind speed - will change to a black icon showing the expected wind gust speed. This black icon will help to inform you in advance of potential hazards that may shape your day, for example severe impacts on transport.
We are aware that some users have difficulty distinguishing weather types with the colours on the maps. The map key below the maps is there to help you in understanding the different weather types and the layers.
If you have a question about the BBC Weather app which isn't covered above, please refer to our App FAQs.
Unfortunately, due to the number of factors that can cause this to happen, and in order to ensure we remain as cost-effective as possible, our small team cannot offer support on an individual basis.
In recent weeks, several users reported that their browser's settings changed to automatically delete cookies (and browsing history) each time they closed their browser. If you have this setting enabled, you will lose your favourite locations.

Some users have reported difficulties loading the forecast, observations and/or pressure maps. Unfortunately, we have not been able to reproduce this issue across the variety of devices, browsers and operating systems that we regularly test against.
Due to the large number of devices, browsers and operating system combinations available, it is not possible for us to offer technical support on an individual basis.
However, the majority of users find that clearing their browser's cache resolves this problem.

During British Summer Time (BST), UTC is one hour behind the time observed in the UK. You should therefore add one hour to the times shown.
UTC is a safer system for displaying information for seafarers as it provides consistency all year round for all locations.
To make sure we're offering the best value for licence fee payers, users outside of the UK have access to the international version of the BBC Weather website. The international version of the website contains advertising.
We try to make sure that the advertising is only visible to people outside the UK, but due to the way certain Internet Service Providers (ISPs) connect you to the web, your location may be detected incorrectly.
Another reason you may be seeing adverts is if you're using a VPN (Virtual Private Network) connection to a server outside of the UK. People often do this for work reasons, for example to connect to their company networks. However, nowadays people are using VPN connections more frequently to access foreign versions of streaming websites. You can see the UK version of our website (advert-free) by disconnecting from the VPN.
If you're viewing the BBC Weather website from within the UK and you can see advertising, please use this form to let us know.
We rigorously test the BBC Weather website on a variety of devices, operating systems and browsers. Many of the issues that our users face can be resolved by updating to the latest version of the browser and checking that you have the correct settings enabled.
Some antivirus/security software or administrator policies on a work computer can also interfere with expected behaviour, e.g. preventing you from changing your preferences (from Celsius to Fahrenheit, for example), on the site.
Unfortunately, due to the combination of available devices, operating systems, browsers and settings that can cause issues to appear, we cannot offer technical support on an individual basis.
However, if you find that something is broken with the website, we advise you to:
If you wish to contact the BBC Weather Centre regarding any issues or queries related to the broadcast content for TV, radio or video forecast, or a query about meteorology, please use the contact us form.
We love receiving your photos that show weather in the UK (and beyond), and we try to use audience photos regularly across our output. If you would like to send us your weather pictures see our guidelines.
If you have suggestions and ideas on how improve the Weather website, please use the contact us form.
Unfortunately, we can't respond to every email, but we do read all the feedback and suggestions you send us to help us prioritise new features and improvements. We know we won't get it right for everyone and welcome constructive criticism, so please feel free to provide any specific examples or details of what is important to you.
We try to make sure there are as few technical problems with the website and mobile apps as possible. We test on a wide range of devices and browsers to provide the best possible experience.
However, if you have identified an issue that is not covered by our FAQs above, please let us know.
A lot of technical issues are quite specific. We therefore ask that you provide as much detail as possible about the problem, such as:
