Flooding in the US state of Texas is expected to worsen in coming days as waters rise following a storm of historic proportions.
A record 30 inches of rain has already fallen on the City of Houston in the wake of Hurricane Harvey, turning roads into rivers.
But forecasters say the total rainfall could nearly double later this week.
US President Donald Trump has promised swift action to help those affected.
He is due to visit Texas on today.
Mr Trump has also approved an emergency declaration for neighboring Louisiana.
Harvey made landfall as a category-four hurricane late on Friday, bringing flooding described by officials as unprecedented.
