Helene is now to blame for at least 90 deaths across a handful of southeastern states. Video: NORTH CAROLINA DIVISION OF AVIATION The U.S. Southeast grappled Sunday with rising death tolls, a lack of vital supplies in isolated, flood-stricken areas and the widespread loss of homes and property while the devastating toll of Hurricane Helene became more clear and officials warned of a lengthy and difficult rebuild. North Carolina Gov. Roy Cooper predicted the toll would rise as rescuers and other emergency workers reached areas isolated by collapsed roads, failing infrastructure and widespread flooding. He implored residents in western North Carolina to avoid travel, both for their own safety and to keep roads clear for emergency vehicles. More than 50 search teams spread throughout the region in search of stranded people. “Many people are cut off because the roads are impassable,” Cooper said. Supplies were being airlifted to the region around Asheville, a city in western North Carolina's mountains known for its arts, culture and scenery. One rescue effort involved saving 41 people north of Asheville. Another mission focused on saving a single infant. The teams found people through both 911 calls and social media messages, North Carolina Adjutant General Todd Hunt said. The storm upended life throughout the Southeast. Authorities were rushing to airlift supplies and restore communications and roads in flooded Asheville on Sunday as residents along the storm-battered Florida coast gathered for church services.
