"Crew decompressed overnight and will return to surface shortly. Hurricane Rina just a little too close for comfort," the US space agency said in a message on the microblogging site Twitter.
The NASA Extreme Environment Mission Operations (NEEMO) team climbed aboard support boats that were waiting at the surface and they were expected to be on dry land by 9:00 am (1300 GMT).
The crew includes Japanese astronaut Takuya Onishi, Canadian Space Agency astronaut David Saint-Jacques, commander Shannon Walker of NASA, and Steve Squyres, an expert on planetary exploration at Cornell University in New York.
They were about midway through a 13-day mission at the Aquarius Underwater Laboratory, the only undersea lab of its kind in the world located three miles (4.5 kilometers) off the coast of Key Largo, Florida.
