Hurricane-turned-tropical-storm Harvey entered its sixth day in the Gulf Coast region Wednesday, as the devastating storm made its second landfall near Cameron, Louisiana.

The most powerful hurricane to hit the United States in more than a decade, Hurricane Harvey has left destruction in its wake, flooding homes and businesses and stranding residents as the rainfall totals continue to climb.

According to the National Hurricane Center, rainfall is expected to continue through Friday in Louisiana and as far north as Kentucky, though the storm should weaken as it moves inland. While the rain has finally moved out of southeastern Texas, the weather service warned Wednesday that “ongoing catastrophic and life-threatening flooding will continue,” and acting Homeland Security Secretary Elaine Duke predicted Wednesday the storm’s effect in the state will require a “many-year recovery.”

Here are the current statistics behind this devastating weather event, which are subject to change as the storm and rescue efforts continue.
