Forecast & Rainfall

Hurricane Harvey rainfall projections.

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.”

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.”
