At 05/04Z, Haiyan had intensified to Typhoon status with sustained winds of 65 knots. Haiyan was located about 400 miles south of Guam moving due west at 14 knots. Rapid intensification is likely and Haiyan is now expected to peak at about 130 knots. Each update to the forecast track has nudged the typhoon further south of Yap - and closer to Palau. The typhoon should pass south of Yap at 06/10Z and north of Palau at 06/20Z. Any additional westward track adjustments would push the center into the Philippines just south of Samar with landfall on Leyte (and eventually Cebu) around 08/03Z. Haiyan has a very large convective envelope and the central Philippines are already preparing for a major storm.
