Hunter Hayes knows a thing or two about hur­ri­canes. He grew up in Louisiana and even named his break­out sin­gle “Storm Warn­ing.” He returned to his home state Fri­day to per­form a ben­e­fit con­cert for a New Orleans hos­pi­tal while the city cleans up after Hur­ri­cane Isaac. He was also sched­uled to sing the national anthem on his 21st birth­day yes­ter­day at the New Orleans Saints game.
