ALERT GMap is smartphone friendly, however, it’s touch features may be difficult for some users to navigate. Desktop/laptop users should find GMap easy to use. This popular map can also be launched by clicking on the MHFD-FWS logo on the alert5 homepage. Zero readouts are not displayed on this map.
A “Lite” version of GMap designed for Twitter followers is another option. To check the operational status of all ALERT rain gages use the station status GMap. A green ‘+‘ is used to show functioning stations and a red ‘x‘ indicates that the station is either out-of-service or discontinued.
Our Contrail website is another great option for viewing ALERT data. The TriLynx NovaStar5 viewer is another choice. And finally, be sure to check out real-time storm/flood data from our latest ArcMap. Custom ESRI-driven ArcGIS maps are relatively easy to create like this one for Boulder County OEM.
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 (shown above) 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 MHFD integrates some of the features from HydroWatch. We welcome any feedback you have concerning these products.
MHFD’s Flood Hazard Inventory Tool (FHIT) contains useful information about building structures, roadway crossings, trails and other features prone to flooding.
