As of 5:00 am today, the eye of STY Haiyan (Yolanda) was located over Leyte Gulf...about 85 km east-southeast of Tacloban City, Leyte or 120 km east of Ormoc City, Leyte...currently moving very quickly west-northwest with a forward speed of 39 km/hr towards Northern Leyte and Northern Panay.

Maximum Sustained Winds (1-min. avg) have increased to 315 km/hr near the center with higher gusts. Typhoon Force Winds (118 km/hr or more) extend outward up to 95 kilometers from the center...and Tropical Storm Force Winds (63-117 km/hr) extend outward up to 240 kilometers. STY Haiyan is a small-sized tropical cyclone with a diameter of 610 kilometers across.


STY Haiyan is expected to maintain its fast and generally straight, west-northwest track throughout the forecast period. On the forecast track, the core of STY Haiyan will make landfall over the towns of Dulag, Tananuan, and Santa Fe or about 10 km south of Tacloban City between 6-7 AM today...and cross Northern Leyte passing over or very close to Ormoc City. This Super Typhoon will be passing over the northern tip of Cebu, very close to Bogo City around on or before noon today then it will start traversing the North Central part of the Visayas through the afternoon...across Northern Panay (very close to Roxas City and Boracay) between 2 to 5 PM...and will be in the vicinity of Coron, Palawan by late tonight. On Saturday afternoon, Haiyan (Yolanda) will exit the Philippine Area of Responsibility (PAR)...and will be approaching the coast of Vietnam on Sunday early morning.

STY Haiyan (Yolanda) will start to weaken slightly within the next 24 through 48 hours as the system makes landfall over North Central Visayas...and will be just a Category 4 TY on Saturday. Advance Intensity Forecast (AIF) shows its 1-minute maximum sustained winds decreasing to just 250 km/hr by Saturday early morning.

The following is the summary of the 2-day forecast outlook and an extended 3-day forecast on this system:

SATURDAY EARLY MORNING: Weakens slightly but remains a very dangerous Category 4 Super Typhoon...moving out into the West Philippine Sea...about 140 km NW of El Nido, Palawan [2AM NOV 08: 12.0N 118.7E @ 250kph].
SUNDAY EARLY MORNING: Already outside of PAR as it approaches the coast of Central Vietnam...weakens to Category 3...about 380 km SE of Da Nang, Vietnam [2AM NOV 09: 14.4N 111.3E @ 205kph].
MONDAY EARLY MORNING: Just barely a Typhoon as it makes landfall over Central Vietnam...about 145 km South of Vinh, Vietnam [2AM NOV 10: 17.4N 105.5E @ 120kph].

*Please be reminded that the Forecast Outlook changes every 6 hours, and the Day 2 and 3 Forecast Track has an average error of 100 and 250 km respectively...while the wind speed forecast error, averages 35 kph per day. Therefore, a turn to the left or right of its future track and changes in its wind speed must be anticipated from time to time.
