I have seen that a lot of people is looking for a way (far from a nice
PC) to get a real time weather update... probably on your cell phone.

When I started flying, I often found myself far from a weather
forecaster or a PC to get the METARs and TAFs for the aerodromes I
needed, so I made a little web page that really helps me with that:

I use a blackberry and am happy with the result.
There is a database with over 9300 fields that you can get your METAR
or TAF reports or locate on a google map.
If you need an additional field, use the comment link to ask for it.
Comments are also welcome.

There are also some images, mainly focused on European weather. Let me
know if you need something else there.

I hope this will help you too.
And PLEASE use a local forecaster whenever available!

Enjoy flying!
