Houston TX in High Water

(2017/08/27) It is the second day after Hurrican Harvey hit Texas. The city of Houston is shown in high water. Live traffic map tells you how the city infrastructure is paralyzed by torrential rain (when you click the link now, it will show differently from this capture image). Most sections of the highway systems show no traffic. Most communities if not in water are probably like isolated islands. There will be more rain and water to come in the following week. Pray for the city!

The following picture is capture 13 minutes later from http://abc13.com/traffic/, but it seems to tell a different story. Green parts mean traffic are in good conditions (good speed). So which one is correct? Maybe BOTH. When there are not many cars (due to bad weather and many flooded areas) on the highway, the speed condition is good.
