Harvey weakened to a tropical storm by midday Saturday and by 4 a.m. Sunday the National Hurricane Center said Harvey continued to cause “catastrophic flooding in southeastern Texas.”

Tracking Harvey is not easy.

There is no exact consensus for what it will do long term, and the most likely scenario is the storm meanders around the region for a couple of days.
