just for the sake of clarification, you may notice that weather.com 
clearly says that 
http://www.weather.com/weather/today/Oaxaca+Mexico+MXOA0069 is

title: "Oaxaca Weather Forecast and Conditions"
description: "Oaxaca weather forecast and weather conditions. Today’s 
Oaxaca weather plus a 36 hour forecast and Doppler radar from weather.com."

they certainly do not purport that the uri refers to "the weather in 
Oaxaca", and clearly state that it's information about the weather in 
Oaxaca, a forcast and a summary of the weather conditions.

The text I offered above, holds true for this resource.
