18Z HWRF and GFS have Fay pretty much near Cedar Key by 2 PM tomorrow. Yes, I saw our local weatherman Dennis Phillips show his "titan" model running Fay SW though Tampa Bay and into the GOM. Titan and Vipir - anyone know what code or platform these models are run off?[/quote][/quote][/quote]
The HWRF model is only used by Tampa TV weather people, is that what I am understanding you saying? Imagine that I learned some thing new here today because I thought the HWRF was a new computer model that will be the operational backbone for hurricane track and intensity forecasts by the National Hurricane Center (NHC).
The following model description can be found in the Product Description Document for the National Centers for Environmental Prediction's Model Analyses & Forecasts[3]:
— The HWRF provides operational guidance for forecasters at the National Hurricane Center in both the Atlantic and East Pacific basins. Hurricane forecasts are produced on demand every six hours at 00, 06, 12, and 18 UTC for up to four tropical storms at a time. The HWRF hurricane model graphics are available at six hour increments up to 126 hours. Often, there are less than 126 hours.
— The model is a nested grid system with an outermost domain and a nested grid with resolutions of 27 and 9 km respectively and 42 vertical levels. The HWRF vortex initialization uses the 6 hour forecast as the first guess, then uses regional GSI 3DAR data assimilation to produce the initial hurricane vortex that matches the intensity and structure parameters provided operationally by NHC. The HWRF is coupled to a high-resolution version of the Princeton Ocean Model for the Atlantic Basin. The ocean initialization system uses observed altimeter observations to provide a more realistic Loop Current and Gulf Stream conditions.

http://www.nco.ncep.noaa.gov/pmb/products/hur/..So how mis-informed I was and now I know its a wishcasting device used by channel 13 and 28 in Tampa. Thank you for clearing that up for me.
give me a break!
