Harvey Approaches Texas Coast

Just a tropical depression 36 hours ago, Hurricane Harvey rapidly strengthened over the very warm waters of the western Gulf of Mexico.  Current forecasts indicate that it will strengthen further, perhaps to a Category 3 storm, before making landfall just north of Corpus Christi.

Counter-clockwise winds of 125 mph or more will lash the coast north of the hurricane's center, producing a storm surge of 9 feet or more in some areas.  Of course, wind damage and widespread inland flooding are also expected.

Indeed, the major problem with Hurricane Harvey is that the storm is moving slowly and will not be whisked away by any approaching fronts.  Rather, the hurricane (or its remnant system) is forecast to meander along the Texas Gulf Coast for several days, dumping prodigious amounts of rain on an area that has already experienced a wet spring and summer.  Two feet of precipitation (if not more) will fall in some locations and widespread, severe flooding is almost certain to occur, perhaps as far inland as San Antonio.
