ALERT GMap is smartphone friendly, however, some touch features may be difficult for some users to navigate. Desktop/laptop users should find GMap easy to use. A station status GMap is also available that shows the location of all gaging stations. Our Contrail website is another great source for viewing ALERT data. A “Lite” version of GMap designed for Twitter followers is another option. And finally, be sure to check out our latest ArcGIS webmap for real-time storm/flood data. A new beta version ArcGIS map is also available with looping radar images.
The AHPS-like webmap is designed for monitoring stream and reservoir water levels. A Google Earth™ option is also available. The NWS AHPS webpage is another good option. AHPS is an NWS acronym the stands for “Advanced Hydrologic Prediction Service.”
The WDT HydroWatch website was Flash™ dependent and is no longer supported by DTN. DTN recently acquired WDT. A replacement WeatherOps app subscription service is available from DTN. An ArcGIS webmap developed by UDFCD integrates some of the features from HydroWatch. We welcome any feedback you have concerning these products.
