module. It turns out the only site I could find gives them out in "dms" format (whatever that is), while Z Weather expects them in some other format. To top it off, it only accepts negative latitudes because apparently it's supposed to be used in the US only - or at least in the north hemisphere. So, unless you're a reasonable programmer (like myself) and know your way around ther guts of Joomla components (unfortunately not my case), if you live in the south hemisphere don't waste your time trying to make any use of this one.
Z Weather only works for USA cities because the weather data from the National Weather Service only supports USA locations.
