A second beach house at Cape Hatteras National Seashore crumbled into the Atlantic Tuesday afternoon after a home collapsed in the early morning hours. 

Officials warned more structures could also fall after the first house was swept into the ocean, as a coastal storm system churned up conditions like overwash, onshore winds and rough surf.  Both homes were unoccupied. 

We’ve had one of the houses fall in overnight. Will probably have another go in today at some point Camacomico Banks Fire Rescue posted Tuesday morning. Officials say all debris will be floating south.

In February, a five-bedroom house collapsed along Ocean Drive, and it could be a sign that the beach erosion rate is increasing. The home was empty when the ocean claimed it, and no one was hurt. 

Debris from that home spread "many miles" before volunteers and the homeowner organized a beach clean-up event, according to Cape Hatteras National Seashore officials.

“Unfortunately, there may be more houses that collapse onto Seashore beaches in the near future,” said David Hallac, superintendent for National Parks of Eastern North Carolina. “We proactively reached out to homeowners along Ocean Drive in Rodanthe after the first house collapse and recommended that actions be taken to prevent collapse and impacts to Cape Hatteras National Seashore.”

Cape Hatteras National Seashore officials plan to work with the homeowner of the latest collapsed home to coordinate clean-up activities. Any volunteers are asked to place debris piles above the high tide line so that it doesn’t get washed back into the ocean.

Weather is playing a part in closing access to parts of the Outer Banks.

Ocean overwash closed N.C. Highway 12 between Oregon Inlet and Rodanthe Tuesday morning, and it's expected to be a problem for this section throughout the week, especially during high tide.

The coastal storm also forced ferry service to be suspended.
