The City of Houston reports that it “is monitoring Hurricane Harvey in the Gulf of Mexico. Houston residents can expect to see a significant amount of rainfall over the next five days, which will likely lead to flooding. It is important that Houston residents stay aware, and begin taking steps in the event Hurricane conditions affect our area in the next few days.”

According to the city, “Impacts to the City of Houston are expected to mostly be significant rainfall. The National Weather Service forecast currently indicates that Houston will see close to 20 inches of rainfall over the weekend and into early next week. This is likely to cause dangerous flash flooding, and will cause area flooding throughout the entire Houston region.”

“Flooding is the main threat to the Greater Houston Area,” KHOU-TV reports, not wind, at least at this point.

Will Hurricane Harvey hit Houston? The Dallas Morning News reports that’s expected to be one of the hardest hit areas. “People are being advised to reconsider any weekend travel plans they have to the coast, and surrounding areas like Houston, where Harvey is expected to hit the hardest,” the newspaper reported. “Those living in the affected areas are encouraged to secure themselves and their belongings by Thursday night” August 24.


Forecast & Rainfall

There is potential in Houston for a lot of rain. “The storm’s sluggish pace increases the odds that Harris County – and areas across southeast Texas – could see levels of rainfall comparable to Tropical Storm Allison or the 2016 Tax Day Floods, but even more widespread,” Houston Chronicle quoted Jeff Lindner, a meteorologist with the Harris County Flood Control District, as saying.

“The potential here is for big rain amounts over a very large area,” Lindner said to the newspaper. “That’s something that’s somewhat unprecedented across the Texas coast.”

There are concerns about Houston refineries. Reports CBS News, “The Galveston sea wall is 17 feet high. A storm surge over that could travel from the Gulf of Mexico, into Galveston Bay, and up the Houston shipping channel, crippling one of the nation’s busiest ports. It’s also home to several major refineries.”

According to KHOU, “Houston is forecast to receive 5″ to 15″ of rain with flooding possible this weekend into early next week. KHOU 11 Chief Meteorologist David Paul warns some isolated parts of Houston could receive up to 30″ of rain, which means we will need to keep a close eye on our bayous.”
