Here's part of the overview section:
Overview and Product Description
The TCI Graphics web site is an internet-based decision-support service consisting of at least four graphics: high wind impacts, coastal flooding impacts, inland flooding impacts, and tornado impacts. During the 2012 Atlantic & Caribbean Hurricane Season, the graphics will be generated and posted by the 23 coastal WFOs listed above whenever tropical cyclone watches and/or warnings are in effect for their area.
Per tropical cyclone hazard, each graphic is based on the most recent threat assessment as centered on a particular geographic area of interest, and is presented in terms of potential impact while using associated descriptions unique to that area. The assessment scheme takes into account the forecast magnitude of the hazard, along with the associated uncertainty of the forecast. Depictions combine the expertise of the local WFO with that of the National Hurricane Center, the Storm Prediction Center, and the Hydrometeorological Prediction Center. The graphics are designed to distill an abundance of complex information into easy to understand colorized maps for decision-making purposes. They provide an "at-a-glance" summary of potential impacts that have the reasonable chance to occur. Consequently, the web site can also be used as a coherent briefing tool. The valid period is for the duration of the event as the graphics do not convey specific timing. Updates will be provided at least every six hours, and will cease when watches and/or warnings are no longer in effect within the specified area.
While all participating WFOs will provide TCI Graphics for each of the aforementioned hazards, some may provide additional graphics (e.g., marine, combined hazards bar charts, etc.) for advanced project purposes.
Important Note:Tropical cyclone forecasts are subject to adjustments with each successive issuance and thereby contain inherent error to some extent. To account for this, TCI Graphics DO NOT depict "expected impacts" as might be assessed deterministically using the most recent forecast (e.g., treating the latest forecast as if it were perfect). Rather, the graphics depict "potential impacts" which also take into account forecast uncertainty (e.g., errors in forecast track, intensity, and size of the cyclone). This serves as a practical least-regret approach for including proportional margins of safety while delivering a more consistent forecast-to-forecast message.
Also, the impact descriptions for each color-filled area are generalized. Impacts realized at exact point locations may be somewhat greater or lesser in extent (e.g., differences in actual impacts to a heavily populated city vs. a nearby marsh).
Examples of Products
Each graphic may have up to five color indicators as follows: Gray | | representing "No (None)" impact(s), Yellow | | representing "Low" impact(s), Orange | | representing "Moderate" impact(s), Red | | representing "High" impact(s), and Fuchsia | | representing "Extreme" impact(s).
Looks like this could be a good idea. Hope it works well, and ultimately saves lives.
