'Beyond anything experienced': Harvey's human impact
Monday, August 28, 2017, 11:00 AM - Though Hurricane Harvey is now a tropical storm, it continues to drench parts of Texas, including Houston, with epic rainfall set to reach around a metre in some areas.
The U.S. National Weather Service said the storm was "beyond anything experienced," and millions of people are experiencing their worst-ever weather catastrophe, with some deaths already reported, and the human impact has been dramatic and widespread.
Thousands of people have been rescued, but still others remained trapped. At one point, Houston's fire chief tweeted that people should not take refuge in their attics unless they had a means of breaking through to the roof if floodwaters rose too high.
A tweet of seniors trapped in a flooded nursing home went viral (they have since been rescued), and Twitter has been filled with people tweeting pleas for help.
Below is a selection of tweets showing how people are coping with the flooding.
