The weather forecast pictures don't match the text.
Firstly, ensure you are looking at the latest picture by pressing Ctrl and Reload/refresh. The graphic is routinely updated twice a day between 0630 and 0800 UTC and at approximately 2200 UTC.

However, the graphic will also be updated at other times when there is a significant change in the forecast. The text is updated three times a day at 0600, 1200 and 1800. The weather symbols are valid for the time shown under the map. The associated text should always be read as this will expand and amplify the graphic.

What is the difference between regional severe weather warnings and early warnings?
The regional warnings are issued when severe weather is expected to cause disruption to traffic etc. over the next few hours. The early warnings are issued when severe weather is expected to cause widespread disruption to traffic etc. over the next few days.
