Can anybody tell me why on BBC News weather forcast that Udon Thani shows up on the Asian map? Important citys like Bangkok, Hong Kong etc and there it is UDON THANI. Even Vienchien is not shown. Looks like Udon is some hugh landmark! This probally shown every hour on TV.

^ Is Pattaya on there too?

Just two in Thailand...Bangkok and UdonThani

I think westers probably has it pretty well sussed in his assessment.
The BBC (whether people like their news coverage or not) are a pretty well clued up organisation and are pretty dam good at the internet & web data.
I suspect that not too many people who visit Patters care one jot about the weather Marmite - but that could just be my prejudices showing through

I'm guessing they choose Udon because it's the furthermost (major) northeastern city. It's not worth listing Pattaya because of it's close proximity to Bangkok.
I'm puzzled why Chiang Mai's not listed.

Since I am in U.S. now if I want to check on forecast/weather for Udon I go to www.wunderground.com which gives many forecast and current conditions around the world

Also have a look here http://www.weather.com/services/

You can see a box that talks about a Firefox add-on. If you install it you have the weather for whichever city you like (I use Nong Khai, but also has Udon etc) displayed like a widget along the bottom of your screen, above the Taskbar.

You can easily click and get radar maps, 10 day forecasts, etc etc.

4-5 years agao I did write everyday to the BBC via email complaining that in Thailand were an awful lot of expats and they skimmed over Thailand then in fact if it was mentioned at all is was a miracle.
Now they concentrate on SE Asia and they put Udon on the map, I am not saying it was me, but after about 6 months something happend and i was surprised, yes maybe not only me but others complained and they saw the error of their ways.

Anyway it is good isn't it no matter how it got there.

Maybe it's because Udon city has the most population of any city outside the Bangkok metro area.

For whatever reason I like seeing it when they do the weather.

Maybe the BBC weather program producer has intrests in Udon Thani after a visit to Thailands entertainment complex

More likely that it's slap bang in the middle of no where and the name doesn't obstruct any where important.
