US-WEATHER-FLOOD

Firefighters help a local resident to cross a flooded street in downtown Charleston, South Carolina on October 4, 2015. Relentless rain left large areas of the US southeast under water and forecasters warned that more heavy downpours could trigger historic flooding in the crucial next 24 hours. The states of North and South Carolina have been particularly hard hit, but the driving rain in recent days has spared almost none of the US East Coast and forecasters say the worst is not over quite yet. News reports blamed the wild weather on four deaths in the United States since Thursday, all in the Carolinas. AFP PHOTO/MLADEN ANTONOV (Photo credit should read MLADEN ANTONOV/AFP via Getty Images)
