WeatherUnderground.com: Wunderground.com map has my weather station in the wrong location or the elevation is wrong.
If Weather Underground has your weather station in the wrong location (longitude and latitude) or elevation is wrong, Wunderground will not fix it for you, and there is nothing we can do.
We recommend creating a new weather station and deleting the old one.
When registering again, drag the red dot to your actual location if it does not match your address. Enter the actual elevation in the bottom right hand corner of the screen.
