Wyoming Flood Awareness Week
Friday - AHPS and Drought Information Sources
The Advanced Hydrologic Prediction Service (AHPS) is a web-based suite of accurate and information-rich hydrologic forecast products. AHPS displays the magnitude and uncertainty of occurrence of floods or droughts, from hours to days and months, in advance. These graphical depictions provide useful information and planning tools for many economic and emergency managers. The hope is that AHPS will enable government agencies, private institutions, and individuals to make more informed decisions about risk based policies and actions to mitigate the dangers posed by floods and droughts.
The current group of AHPS products covers forecast periods ranging from hours to months. It also includes valuable information about the chances of flood or drought. This information is presented through user-friendly graphical products. The information, such as the flood forecast level to which a river will rise and when it is likely to reach its peak or crest, is shown through hydrographs. Other information includes:
An additional feature of the AHPS Web site is a map of the river basin and various points along the river for which information is available. The data are not limited to information about floods, but can also provide information about potential droughts. This core suite may change over time reflecting the changing needs communicated by customers.
Throughout much of the first decade of the 21st century, Wyoming was mired in drought. Recent years have provided some relief, but the drought served as a reminder of the difficulties that arise in the arid west when snowpack and late spring and summer rains are inadequate to provide necessary water supplies. Population growth and new demands on water supplies across the west have made drought and water monitoring an important discussion topic.
