Google is providing current weather information and cloud data from around the world on its Google Maps application, by an arrangement with The Weather Channel's weather.com and the US Naval Research Laboratory.

The new "weather layer" can be activated through a widget in the upper right corner of Google Maps. Clicking on the weather icon for a particular city opens a window with data like current humidity and wind conditions, as well as a forecast for the next four days, said Jonah Jones, a Google user experience designer.

Users can also change the units of wind speed and temperature on the left hand panel, and enable or disable the viewing of clouds when zoomed out from the map.

The weather data comes from weather.com, while information on cloud coverage is provided by the Naval Research Laboratory, Google said.

Google Maps already offers information on topography and current traffic conditions for a number of locations. It added the live traffic feature to 13 countries in Europe in July.
