Model consensus for south Texas this Friday is growing much more concerning. HWRF, HMON, GFS, ECMWF, GEM & GFS Ensemble Members with almost 100% unanimity on a landfalling Texas hurricane Cat 1 to Major. Some runs hang it around just inland, others around the coast - with potential for very severe flooding if either of those scenarios verify (inland and/or coastal).

This is a few days out, and these runs can change. "Harvey" is not even yet a tropical cyclone again, so large shifts in track and intensity are quite possible. Image credits Tropical Tidbits.
