Dove Palau in March 2003. German Channel was ok but not as spectacular as the other sites, Blue Corner or Ngemelis Wall. The viz was hazy, only about 25 ft. I've heard that Ulong channel is also a great dive. Palau is about 800 miles southwest of Guam.
Yap was hit by a typhoon on Thursday April 8. Winds exceeded 115 mph. I have read that there has been extensive damage to the island. Palau is about 300 miles southeast of Yap so I doubt there was any damage there.
Palau Dive Sites:
Blue Corner - This is one of the best spots in the world. Sharks swimming six feet in fornt of you. A Nepoleon Wrasse behind you, Pyramid Butterfly fish and a school of chevron Barracuda 20 feet high and 15 feet around. This ignore all the "regular" tropical fish in the area, Triggerfish, parrott fish, octopus, Anenome Fish and more.
Ngemelis Wall - Turtles, Sharks, Huge Seafans and colorful corals a great dive.
German Channel - A cleaning station wiht alot of Giant Clams, and a large variety of coral.
These are the sites i dove there.
enjoy the trip.
