Trump jets in to Texas to view 'epic' flood damage as death toll rises to 18

• Trump comments 'What a turnout!' while in Texas to survey damage
• At least 18 people confirmed dead and vital dam begins to overflow
• Tropical storm Harvey - live updates

Donald Trump flew to Texas on Tuesday to view the trail of destruction from tropical storm Harvey that has killed at least 18 people, displaced tens of thousands and defied conventional measurements.

But Houston was braced for fresh damage as a vital dam began overspilling and more rain was forecast in the continued onslaught from one of the worst natural disasters in US history. On Tuesday evening, mayor Sylvester Turner announced a curfew between midnight and 5am "to ensure public safety" and "prevent potential criminal acts". (Earlier it was announced the curfew would begin at 10pm). However, the curfew did not apply to "flood relief volunteers, those seeking shelter, first responders, and those going to and from work".
