Issued at: 12:00 AM PhT (16:00 GMT) Friday 08 November 2013

Super Typhoon HAIYAN (YOLANDA) has turned into a 305 km/hr howler…and is considered as the most powerful tropical cyclone ever to develop since Super Typhoon Tip of October 1979…moving closer to Eastern Visayas…likely to make landfall over Eastern Leyte or Southern Samar after sunrise today.

activetrack

Important Note: This typhoon is similar in track but more powerful in strength of Super Typhoon MIKE (RUPING) which passed across the Visayas on November 12, 1990 which devastated much of Central Visayas paricularly Cebu.

Residents living along the eastern seaboards of the Philippines from Bicol Region…down to Northeastern Mindanao should continue monitoring the approach of this destructive typhoon for possible unprecendented track changes. Plans for emergency situations and/or disaster management planning must be completed as soon as possible as the dangerous cyclone is only 6 hours away from hitting land.

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.

Maximum Sustained Winds (1-min. avg) have increased to 305 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 from the center. STY Haiyan is a small-sized tropical cyclone with a diameter of 610 kilometers across.

2-DAY FORECAST OUTLOOK*

STY Haiyan is expected to move fast in a generally straight, west-northwest track throughout the forecast period. On the forecast track, the core of STY Haiyan will make landfall over the central-eastern shores of Leyte, about 45 km south of Tacloban City between 8-9 AM Friday and cross Northern Leyte passing over or very close to Ormoc City just around noontime Friday. This Super Typhoon will be passing over the northern tip of Cebu, very close to Bogo City around 2 PM then it will start traversing the North Central part of the Visayas through Friday evening…across Northern Panay (very close to Roxas City and Boracay) late Friday afternoon…and will be in the vicinity of Coron, Palawan by Friday midnight. On Saturday evening, Haiyan (Yolanda) will exit the Philippine Area of Responsibility (PAR).

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 215 km/hr by Saturday evening.

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

  1. How much damages did our province get from this devastating typhoon? There is still no contact in certain municipalities of the province. I hope the authorities are doing everything they can to restore the communication lines so as for us, native Biliranons who are far from our homeland, to know and not be blinded on what’s going on there. We just hope for zero casualty. And I hope that the communication lines will be restored as soon as possible. I am just a concerned loved one and citizen of Billiran. Bangon Biliran!
