Most river forecast points in the WFO Tulsa Hydrologic Service Area (HSA) have become enhanced with new Advanced Hydrologic Prediction Service (AHPS) capabilities.

AHPS river forecast points consist of at least a short-term hydrologic forecast in text and graphical format, graphical maps of the river gage location, river level impacts at critical heights, and long-term probabilities of flow, height, and volume. The addition of probabilistic forecasts will give the user more information to make a risk-based decision.

To see the new AHPS-enhanced forecasts, please go to the WFO Tulsa website and click on the link marked “Rivers & Lakes AHPS” in the left column. The AHPS river forecast points are depicted with a circle icon.

Probabilistic forecasts are scheduled to be added to more forecast points in the Tulsa HSA over the next several years. For more information about AHPS, please go to the following website:
