Hurricane Irene has the potential to be a "catastrophic event," Al Roker told the "Today" show audience.
Friday's show led off with Roker in Duck, North Carolina. Standing on an ominously empty beach, Roker said that Irene, which is hurtling towards the East Coast, was "potent and dangerous," and led viewers through the deadly and destructive path the hurricane is likely to take. There could be, he said, storms, coastal flooding, beach erosion, winds, rains and flash floods as a result of Irene. Cities up and down the coast will be hit with anywhere between five and 25 inches of rain.
"This could be a catastrophic event up and down the Eastern seaboard for 65 million Americans," Roker said.
