How Houston is responding to tropical storm Harvey

Tropical storm Harvey has dropped as much as 30 inches of rain in some areas in Texas, and may add another 20 inches to that total. That’s four feet of rain in just a few days. Tens of thousands of people have had to seek shelter from the storm. We hear from a Houston resident affected by the storm, a leader of a search and rescue team, and an editor coordinating the Houston Chronicle’s coverage of the storm.
