Storm Track Predictions

Storm track products issued by METEOROLOGIST will attempt to depict the aerial coverage of the flooding threat, storm movement, timing and storm size. This product will be prepared using an appropriate map and disseminated via fax. Predicted storm tracks and associated envelopes of storm influence will be plotted on the map in accordance with the SOP. Descriptive text will be included to ensure proper interpretation. This product will be transmitted only when MESSAGES are issued. When appropriate, updates to this product will be issued 30-60 minutes prior to flooding to show refined storm tracks and identify specific drainage basins affected.

Prediction Evaluation Program (PEP)

The Prediction Evaluation Program will evaluate the forecast products offered on MESSAGE days to local government users. All PEP activities will be completed within 48 hours of each MESSAGE day to check the following aspects of the forecast services:

1. The timeliness of MESSAGE issuance (i.e., the operational lead-time of the MESSAGE will be compared to actual event occurrence).

2. The accuracy of the MESSAGE forecast of QPF, location, storm tracks and associated weather will be compared to actual occurrence to determine false alarm rates, specificity of the forecast and service rendered to the user.

The PEP may allow user ideas to be implemented or tested during the current flood season.
