I have just updated my South Coast Travel public google map to include placemarks with links to the BBC and Met. Office weather reports. I am disappointed that they have no obvious weather icon and that the i icon is available in only one colour.
I did poke around the Google maps API pages and may take this further so that I can incorporate the page into www.davelevy.info, but if its like yahoo, this could be a bit difficult.
Otherwise its screen shot and link to the Google Maps URL
