Flood Alert System (FAS2) incorporates adjusted real-time NEXRAD radar data, GIS, hydrologic models and the Internet to provide advanced warning to the Texas Medical Center (TMC) in Houston, Texas. It has been tested during 2006 season with excellent performance and was used as a platform to develop a real-time hydraulic prediction tool---the Floodplain Map Library (FPML) system. FPML provides inundation maps in near real time linking with NEXRAD radar over the watershed. FPML is also compatible with storm surge input in order to predict inundation maps during extreme coastal weather conditions, which will improve emergency personnel's ability to initiate evacuation strategies at many levels.
