I agree with you 100%, David, but especially the following.

Another area of confusion is trying to work out whether the
general weather information being given is for England or the
UK as a whole. It isn't always clear when the presenter refers
to the 'far north' or 'across northern areas' whether he (or
she) is referring to northern England or Scotland. If they
made a point of suffixing 'England' or 'Scotland', that would
solve the problem, but they all too often don't bother, so the
weather predictions become meaningless.
Regards... David Allan (Tyne & Wear).

Some of them (not only weather forecasters) need to remember
that they're not the London Broadcasting Corporation, or the
English Broadcasting Corporation.

Referring to 'the north' or 'the north-east' or 'the north-west'
is at best meaningless and at worst misleading. There isn't
quite the same problem with 'the south' and 'the south-east'
because they generally refer to those parts of Britain, and
that's fair enough when it's the British Broadcasting
Corporation.

It's also not unusual for entire chunks of the country to be
missed out entirely. "And now for Scotland. There will be rain
in the west and sunny spells in the south." Then I wait in vain
to hear anything about the north-east of Scotland, where I live,
but apparently there isn't going to be any weather here at all,
because it isn't mentioned.
