Harvey was officially reclassified as Tropical Depression Harvey.
Harvey completed a rapid intensification cycle, quickly upgrading the storm to an 85-mph hurricane. Both StormGeo and the NHC were forecasting that Harvey would make landfall as a major hurricane along the lower or middle Texas coast, with little motion shown thereafter.
It was becoming readily apparent that a major-landfalling hurricane and extensive flooding event was on tap for southeast Texas. Advisories at the time were forecasting rainfall totals of more than 20 inches with discussions indicating that some models were forecasting upwards of 4 feet of rain. This is an incredibly high forecast total but ended up being on half the amount of rainfall measured. Overnight, Harvey made landfall near Rockport, TX as a Category 4 hurricane, with winds of 130 mph and a Hurricane Severity Index (HSI) of 25.
