“We face walls of water at our coasts, along our rivers, across our farmland, in our cities and in our towns,” North Carolina Gov. But its slow forward movement means that coastal and southeastern areas will still get the brunt of its deluge. Parts of North Carolina already have received a record-breaking 30 inches of rain, and many areas are expected to get at least 15 more inches. Some areas are already experiencing flash flooding, which occurs when rainfall is so great that it overwhelms drainage systems. But a growing concern is river flooding, which happens as tributaries and basins drain into main rivers, causing them to overtop their banks.
