 |
24-hr Accumulated Precipitation During Previous Hydrologic Day |
| (This image can be seen in more detail by clicking on the image or its label.) It shows the 24-hr precipitation accumulation for the previous hydrologic day (ending at 7AM EST) as computed from precipitation processing software. This product is updated usually by 8AM EST each day. |
 |
Previous 24-hr HAS QPF Image Ending 7AM EST |
| (This image can be seen in more detail by clicking on the image or its label.) It shows the previous day's 24-hr total QPF generated by the HAS Unit at the RFC (which should be valid for the same period as the accumulated precipitation in the cell above [except for short delays when one image is updated before another]). The QPF amounts shown here were used as input to NWS Hydrologic River Models. |
 |
Absolute Error of HAS Forecast |
| (This image can be seen in more detail by clicking on the image or its label.) It shows the absolute error of the previous day's 24-hr total precipitation forecast generated by the OHRFC HAS Unit in comparison to actual precipitation estimates (see top row). |

Previous 24-hr HPC QPF Image Ending 7AM EST |
| (This image can be seen in more detail by clicking on the image or its label.) It shows the previous day's 24-hr total QPF generated by the Hydrologic Prediction Center (which should be valid for the same period as the accumulated precipitation 2 cells above [except for short delays when one image is updated before another]). This image is generated from national QPF guidance provided by the Hydrologic Prediction Center. |

| (This image can be seen in more detail by clicking on the image or its label.)

24-hr Accumulated Precipitation During Previous 00z-00z Hydrologic Day |
| (This image can be seen in more detail by clicking on the image or its label.) It shows the 24-hr precipitation accumulation for the previous hydrologic day (ending at 7PM EST) as computed from precipitation processing software. This product is updated usually by 8PM EST each day. |
