. Coast watch. Marine resources; Oceanography; Coastal zone management; Coastal ecology. UNC Sea Grant 7:1f V February, 1980 NORTH CAROLINA STATE LIBRAK RALEIGH N. C Doc. A SEP i 8 1980 Illustration by Neil Caudle. /4s a hurricane moves ashore, crashing waves wrench buildings from their foundations Hurricanes: when the roofs fly and the floors float If you are at the coast and a hurricane warning is issued, leave. Get far away to high ground. Sure, you'll wonder what it would be like to stick around, watch the fireworks. Don't do it. Read this instead. As the windspeed accelerates beyond 74 mph, you know you're in a hurricane (not like David, last sum- mer. He was pooped before he got here). That's also about the time things start learning to fly. The clay flower pot just left a dent grinning in the hood of your car. The garbage can looks like Mercury I lifting off and is just about to dive through the $200 plate glass window and splash down on the coffee table. . Okay, maybe you had the good sense to board up those windows. The house shudders from the impact of the mis- sile, but nothing cracks. The wind reaches about 80 mph, too much for the average roof. You can't hear them for the din of the storm, but the shingles are peeling off and sailing like frisbees. The wind shoves and lifts your roof, trying to make it into an airplane, a function for which it is fairly well designed. About now, were you in the attic, you might see the rafters rip loose from the wall, their little nails clutching air, so that the wind can really get a grip . . Or maybe your house was built in the last couple of years. The revised building code declares that new houses on the coast must have enough metal straps and connectors to hold everything together, so long as the blow doesn't get stronger than about 110 mph. Assume the contractor didn't fudge. Assume this is an average hurricane, not a Camille, for example, which struck Mississippi in 1969 at about 172 mph. The roof won't take wing
