Historic flooding continues to worsen in Houston as the remnants of Hurricane Harvey douse southeastern Texas with rain. Emergency personnel used motorboats, airboats and other vehicles to rescue more than 2,000 people in the greater Houston area on Sunday.
Harvey washed over major highways, including Interstate 45 seen above, as flooding spreads. Houston has a population of more than 2.3 million.
As Harvey lingers around Texas' Gulf Coast, where it is forecast to remain for several more days, it is drenching parts of the region with a year's worth of rain in the span of a week.
