According to the latest NWS Guam Local Statement TS Haiyan is expected to pass about 10 miles south of Woleai Atoll around 8PM local time (5:00 AM EST) as a typhoon. This would likely put the island in the northern eyewall. Typhoon warnings are in effect. As per the local statement 75-85 mph winds are expected as well as a 2-4' surge above high tide. According to Wikipedia about 1,100 people live on the island. From what information I've come up with on the topography of the island it appears to be a low coral atoll - not exactly a place you'd want to ride out a typhoon. Hopefully Haiyan will clear the island before getting beyond a category 1.

Further ahead are Yap and Palau and hopefully the storm will shoot the gap between them but it may be a little close for comfort for Yap. There are typhoon watches in effect for both islands. Haiyan is expected to be Cat. 3-4 intensity passing through that area.

And as Ed mentioned the Philippines figure to take a big hit from this one too - but that's about 3 1/2 days away. The Philippines are already dealing with their own system, TD 30W, which is slamming the southern islands with heavy rain and wind. As of now it looks like Haiyan will hit areas further north than where 30W is hitting.
