Hurricane Harvey made landfall as a Category 4 storm along the southeast coastline of Texas over the weekend, the most powerful storm to hit the United States since 2004. As the storm lingers in the region, rainfall has caused major flooding in the Houston area and south Texas, leading to thousands of people needing rescue and evacuation.
