You can now access weather conditions through Google Maps "with one click" using a "mapplet". From the press release:
"The mapplet's weather bubbles expand with a click to display HiRAD data for the point of interest including temperature, humidity, wind speed, and UV Index along with an observation of overhead sky conditions, which is unique to the HiRAD system. Forecast links including hourly, tomorrow, and 10-day are in the expanded bubble along with a link to a video forecast for the selected location. In addition, during severe tropical weather, users will see a Hurricane Central option on the mapplet that will enable them to track an active storm on the map."
You can access the applet through the Featured Content links in the left sidebar of the
Google MyMaps page.
The Weather Channel has also been selected to provide a weather data layer for Google Earth.
"Current conditions in the Google Earth weather data layer are presented in a pop up window and include temperature, humidity, wind speed, pressure and dewpoint, along with an observation of overhead sky conditions. This is presented with forecast data including a 36 hour forecast and links to hour by hour and 10 day outlooks on weather.com. Also available are radar images on the map which are provided by weather.com and Weather Services International (WSI) via a product known as NOWrad."
To try it out you'll need to download the
Google Earth program. Once installed, open it and select the Weather checkbox underneath the "Layers" category on the left-hand sidebar.
