HPC is providing a subset of its product suite in KeyHole Markup Language (KML) format.   KML is used by a variety of GIS and mapping applications, including Google Earth, ArcGIS Explorer, Microsoft Virtual Earth, NASA WorldWind View, and numerous others, to display geospatial data on two-dimensional maps and three-dimensional Earth browsers. Currently, the following products are available in KML format:

• Quantitative Precipitation Forecasts (QPFs)
   
  Includes the latest 6- and 24-hour forecasts through Day 3 and as of April 7, 2011, multi-day (Day 1-2, 1-3, 4-5, and 1-5) QPFs through Day 5.
   
• Significant River Flood Outlook
• Winter Weather Forecasts (available September 15 - May 15)

Note to Google Earth users (12/29/2011): As of version 6, Google has corrected a problem with their network links that resulted in poor color rendition. Consequently, the complete QPF packages and 24-hour Days 1-3 QPFs should now display correctly.
