Hurricane Harvey settled over southeast Texas early Saturday, lashing the state's Gulf Coast with damaging winds and dumping torrents of rain over hundreds of miles of coastline that braced for what forecasters predicted would be life-threatening storm surges -- basically walls of water moving inland.
Harvey made landfall shortly after 11 p.m. Friday, just north of Port Aransas as a monstrous Category 4 storm, the National Weather Service said. Forecasts call for as much as 30 inches of rain to fall by next Wednesday, with some areas getting as much as 40 inches, according to the hurricane center. Meanwhile, the storm surge could bring flooding of 6 to 12 feet to a coastal area that includes Matagorda Island and Port O'Connor.
As Harvey slammed the Texas Gulf Coast, the National Hurricane Center warned Texans to prepare for "life-threatening flash flooding" in coming days that could be "catastrophic."
More than 211,000 homes and businesses were without power early Saturday, leaving locals both in the dark and without air conditioning in the August heat. The National Weather Service warned that some residents may not be able to return to their homes for weeks or months.
"In terms of economic impact, Harvey will probably be on par with Hurricane Katrina," Brian McNoldy, a senior hurricane researcher at the University of Miami, told the Associated Press. "The Houston area and Corpus Christi are going to be a mess for a long time."

City officials notified residents to "boil their water prior to consumption (e.g., washing hands/face, brushing teeth, drinking, etc)" to kill all potentially harmful bacteria and other microbes. "Water for drinking, cooking and ice making should be boiled and cooled prior to use for drinking water or human consumption purposes.

Rockport, Texas, a coastal city of about 10,000 people some 30 miles northeast of Corpus Christi, was directly in the path of Harvey when it came ashore. The city had peak wind surges of more than 125 mph, according to the National Weather Service.
Volunteer Fire Department Chief Steve Sims said there were about 15 firefighters at the city's fire station waiting for conditions to improve enough for their vehicles to safely respond to pleas for help. "There's nothing we can do at this moment. We are anxious to get out there and make assessments, but we're hunkered down for now," Sims said, according to an Associated Press report.
Fire Department spokeswoman Gillian Cox told the Corpus Christi Caller-Times that the roof of Rockport's high school has partially caved in. But Cox says social media posts that the school has "disappeared" are inaccurate.
Rockport City Manager Kevin Carruth told the newspaper that the courthouse also sustained major damage. Carruth said a cargo trailer was halfway in the building.
Earlier Friday, Rockport Mayor Pro Tem Patrick Rios offered ominous advice, telling a local TV station that those who chose to stay put "should make some type of preparation to mark their arm with a Sharpie pen," implying doing so would make it easier for rescuers to identify them.

The only trick is finding it. When Facebook does a server-side activation, you'll usually see a notification right at the top of the app. But if you want to access the feature yourself, it requires a bit of menu-diving."

The National Weather Service says winds could leave homes uninhabitable for weeks or even months. Storm surge could reach 12 feet -- that's strong enough to wash away vehicles, Begnaud reports.
