I'm looking at the BAMM/BAMD, LBAR, and A98E models, also from 0600 UTC (2AM EDT).

BAMM, BAMD, and LBAR all show a *direct* hit on Houston.

Models explained below (from Accuweather):

A98E - National Hurricane Center Atlantic 1998 Early Model
BAMM - Beta and Advection Model (Medium Layer)
BAMD - Beta and Advection Model (Deep Layer)
LBAR - Limited Area Barotropic Model
GFDL - Geophysical Fluid Dynamics Laboratory Model


A98E - A statistical track model which looks at past storms which formed in the same place, and mixes this forecast with upper-level forecast model data from the GFS. Storms are classified based on location and movement, then specific meteorological equations are applied.

BAMM/BAMD - A track model which uses an altered version of forecast model data from the GFS with special meteorological equations that predict the evolution of tropical storms, including taking into account the "beta effect" of the earth's rotation. The BAMD uses an average of winds over the entire atmosphere from top to bottom (good for big storms), while the BAMM uses a medium vertical average (good for medium storms). There is also a BAMS (shallow) for small storms.

LBAR - A an altered version of forecast model data from the GFS with special meteorological equations and techniques (different from the BAM), including an average of winds over the entire atmosphere from top to bottom, that predict the evolution of tropical storms.

GFDL - An advanced 3-dimensional weather forecast model developed specifically for predicting hurricane movement. (resolutions).

Austin stations are showing Rita hitting closer to Beaumont. We were needing the rain in central TX, but looks like that's not gong to happen.

Yes, the models are now recentering over Galveston - especially the leading models. Here's GFDL. It is also showing a direct hit on Galveston/Houston.
