[Fraug 5/16/2014] Monitoring streamflow and water levels
We recently updated a number of ALERT webpages with AHPS features. AHPS is a NWS acronym that stands for Advanced Hydrologic Prediction Service. See http://water.weather.gov/ahps2/index.php?wfo=bou for more information about AHPS. The legend provided was acquired from the NWS AHPS website. The yellow “Near Flood Stage” is also commonly referred to as the “Action Stage.”
Our AHPS-like ALERT webpages use the same AHPS reference levels. These levels are used by NWS as guidance for issuing flood advisories and warnings. Three UDFCD webpages that currently employ this feature are:
- Contrail Stage Summary Table by OneRain
- ALERT Maps by WET
- ALERT Streamflow Map by LRE
