New River Observation and Forecast Website

The new NWS Hydrologic website, the National Water Prediction Service (NWPS), https://water.noaa.gov/ was released March 27, 2024.

Note, clicking the Rivers and Lakes tab on weather.gov/mkx will go to the legacy page. To get to the new page, Hover over the Rivers and Lakes tab, then click the link that pops up, titled National Water Prediction Service (NWPS).

Some features of the new website:

Mobile-compatible
Dynamically-plotting hydrographs
Improved web map functionality and improved base maps and hydro-specific spatial layers
Application Programming Interface (API) - partners can leverage directly into their own applications

A summary of these features, along with video demonstrations is on this Story Map.

The legacy AHPS website will remain active for roughly 60 days after the new site goes live. Prepare to update your bookmarks and links during this time.

New URLs:

The links to river gauge pages will go from:

https://water.weather.gov/ahps2/hydrograph.php?wfo=mkx&gage=XXXW3 to https://water.noaa.gov/gauges/XXXW3

The direct links to static hydrographs will go from:

https://water.weather.gov/resources/hydrographs/XXXW3_hg.png to https://water.noaa.gov/resources/hydrographs/XXXW3_hg.png
