There's really not a lot you can do to prepare a pool for a hurricane, other than to make sure any loose (as in not bolted down) items are removed from the yard and are stored in a secure area. With an above ground pool the biggest storm concerns are any debris blown into the pool that tears the liner, and fallen trees crushing the pool walls. I would not leave a soft sided pool up in a hurricane, but a standard "permanent" above ground pool filled with water can withstand very high winds without problem. Covering the pool to protect it from a hurricane is a waste of time.
What you can do ahead of time is be prepared for the clean up. My pool had so much organic debris after Ike that the water turned black within 24 hours after the storm. If your area takes a direct hit you may be without power for several days. I would start with bringing the pool to shock level about a day before the expected landfall. If you lose power after the storm, pour a 96 ounce jug of bleach around the perimeter of the pool and brush well to mix. Use a deep leaf net/rake to scoop the debris off the bottom of the pool. Make sure you have plenty of bleach on hand, a pool brush, and a couple of boxes of plastic garbage bags for debris clean up.
