Rescue crews in the Carolinas worked methodically throughout the day on Monday, plucking people to safety from the flooding left by Hurricane Matthew's deadly haymaker. Responders pulled people from their submerged homes, situated them in rafts or choppers and whisked them to safe and dry ground. The storm's US death toll climbed to 21 on Monday, with North Carolina reporting 11 deaths, Florida reporting four, and three each in South Carolina and Georgia. President Obama on Monday declared a major disaster in North Carolina and ordered federal aid to supplement state, tribal and local recovery efforts.
