Storm drenches Florida and causes floods in South Carolina as it moves up East Coast

A powerful storm caused flooding and damage as it moved up the East Coast, drenching Florida and inundating South Carolina with record rainfall. Rising sea levels driven by human-caused climate change mean even relatively weak weather systems can now produce storm surges previously associated with hurricanes, said Meteorologist Jeff Masters, co-founder of the Weather Underground. In South Carolina that's worsened by natural subsidence along the coast.
