True. The last Ioke statement available on the Central Pacific Hurricane Center's website noted that winds and pressure were being estimated from satellite guidance. Since the hurricane passed the International Date Line, it is now being monitored by the Joint Typhoon Warning Center.
Hurricane Ioke has been on a U.S. minor outlying territories destruction tour. It struck the usually-uninhabited Johnston Island late last week as a category 2. According to news reports, thirteen people aboard an Air Force research vessel in the vicinity took shelter from the storm in the island's hurricane-proof bunker (one of the few standing structures there since the military pulled out a few years ago) instead of riding out the storm on the ship. They weathered the storm and on their way back to Honolulu, but the research vessel's communications equipment was damaged. Depending on the equipment they had on their ship and whatever was left on the island, they might have taken readings when the storm passed.
Fortunately, it doesn't look like Guam is next on Ioke's U.S. territory destruction tour. Japan might not be so lucky, if the track continues as expected - but there's a long way for this super typhoon to go, and it will likely lose a lot of strength before then. Here's the track map:
