Hurricane Harvey made landfall August 25th, 2017 and continues to flood parts of Texas. Some areas have seen over 40 inches of rainfall. The US National Weather Service tracks the heights of rivers and designates the point at which they are considered to be flooding. Measurements for Texas on Wednesday morning showed levels in some areas around Houston to be 25 ft above “flood” level, and flooding was starting to affect neighboring areas of Louisiana. But 150 miles (240km) to the west in Austin, river levels have barely been affected.
