A new method of monitoring and forecasting flash floods has been developed with the advent of virtual globe software using high resolution photography. By overlaying real-time weather radar data, watershed boundaries and the locations of low water crossings on a three dimensional representation of the terrain, a meteorologist can easily determine in which watershed the rain is falling and which low water crossings might experience flash flooding. The use of virtual globe software allows forecasters to provide more detailed and accurate flash flood warnings, thus leading to more effective response by those affected. By providing the weather radar, watershed boundary, low water crossing and weather warnings in the Keyhole Markup Language file format the information can quickly and easily be shared with others outside the forecast office. Emergency managers and first responders can use these same data to help them better react to a developing flood situation. Ultimately, geobrowsers can be a valuable tool in protecting life and property from flash floods. This paper will examine operational use of virtual globe software and Keyhole Markup Language formatted files to integrate meteorological and hydrological data in support of flash flood warning operations.
