Do not use this for life or death decisions. This update is intended for additional information purposes only. Kindly refer to your national weather agency for official warnings, advisories or bulletins.


As of 5:00 pm today, the eye of TY Haiyan (Yolanda) was located over South China Sea...about 735 km west-northwest of Coron, Palawan or 640 km southeast of Da Nang, Vietnam...currently moving very quickly west-northwest with a forward speed of 33 km/hr towards Central & Northern Vietnam.

Maximum Sustained Winds (1-min. avg) have decreased to 195 km/hr near the center with higher gusts. Typhoon Force Winds (118 km/hr or more) extend outward up to 85 kilometers from the center...and Tropical Storm Force Winds (63-117 km/hr) extend outward up to 240 kilometers. STY Haiyan remains an average-sized tropical cyclone with a diameter of 835 kilometers across.


TY Haiyan is expected to continue moving rapidly in a west-northwest track within the next 24 hours...turning northwest through 48 hours. On the forecast track, the core of TY Haiyan will continue cruising fast very near the coastal areas of Central Vietnam from Hoi An to Than Hoa Cities on Sunday morning through Monday morning. On Sunday morning, Haiyan will make landfall somewhere along the coastal areas of Thai Hoa, Than Hoa and Nam Dinh...and will be passing over or very close to the city of Hanoi Sunday afternoon.

TY Haiyan (Yolanda) will continue losing strength within the next 24 through 48 hours as the system traverses the slightly cooler waters of the South China Sea...and will be just a Tropical Storm (TS) on Sunday afternoon or evening after the system makes landfall over Northern Vietnam. Advance Intensity Forecast (AIF) shows its 1-minute maximum sustained winds decreasing to just 160 km/hr by Sunday afternoon.

The following is the summary of the 2-day forecast outlook on this system:

SUNDAY AFTERNOON: Weakens to a Category 2 Typhoon as it approaches the Northern Vietnam while sidesweeping the coastal and shoreline areas of Central Vietnam...about 115 km North of Da Nang, Vietnam [2PM NOV 10: 17.1N 108.4E @ 160kph].
MONDAY AFTERNOON: Makes landfall over Northern Vietnam...weakens to TS...about 25 km SE of Hanoi, Vietnam [2PM NOV 11: 20.9N 106.0E @ 65kph].

*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.
