Saudel is moving northwest at 7 mph. It is expected to maintain this northwest course before turning more west-northwest late Saturday as Saudel passes through the far Northern Mariana Islands. Though the forward speed has decreased, a quicker motion is expected to resume Friday. The latest forecast track has shifted a little farther west and now brings damaging winds closer to Saipan and Tinian. Maximum sustained winds remain at 40 mph. Saudel, having struggled to get better organized today is now showing signs of improving organization and this should result in a steady intensification heading into Friday midday, perhaps with a period of rapid intensification later Friday into Saturday. Saudel could become a typhoon Friday night and pass through the far Northern Mariana Islands as an intensifying category 3 typhoon. Tropical storm force winds extend outward from the center up to 150 miles to the southwest and up to 115 miles elsewhere. NEXT ADVISORY ------------- An intermediate advisory will be issued by the National Weather Service at 1100 PM ChST followed by the next scheduled advisory at 200 AM ChST early Friday morning. $$ Stanko/W.
