Typhoon WUTIP (PAOLO) Update #007


for Monday, 30 September 2013 [9:41 AM PhT]


Issued at: 7:30 AM PhT (23:30 GMT) Monday 30 September 2013

Typhoon WUTIP (PAOLO) has weakened slightly as it continues to move closer to Central Vietnam endangering the area...likely to make landfall late this afternoon.

Meanwhile, Tropical Disturbance (LPA) 95W [QUEDAN] continues to consolidate as it moves west across the Central Philippine Sea. Its center was located about 880 km east of Borongan City, Samar (11.6N Lat 133.5E Lon)...with maximum winds of 40 km/hr near the center. Various forecast models suggest this system could become a Tropical Cyclone within the next 06 to 24 hours with a northerly track across the open seas of the Western Pacific Ocean...and is not a threat to the Philippines. This disturbance has a high chance (>50%) of developing into a Tropical Cyclone within the next 24 hours.

Residents and visitors along the coastal areas of Central Vietnam and Hainan Island should closely monitor the development of Wutip (Paolo).

As of 5:00 am today, the eye of TY Wutip (Paolo) was located over the western part of the South China Sea...about 115 km south-southwest of Sanya, Hainan Island or 170 km northeast of Da Nang, Vietnam...currently moving west-northwest with an increasing forward speed of 22 km/hr towards Central Vietnam.

Maximum Sustained Winds (1-min. avg) have decreased to 150 km/hr near the center with higher gusts. Typhoon Force Winds (118 km/hr or more) extend outward up to 45 kilometers from the center...and Tropical Storm Force Winds (63-117 km/hr) extend outward up to 175 kilometers. Wutip (Paolo) remains an average-sized tropical cyclone with a diameter of 555 kilometers across. The 24-hour rainfall accumulation near the center of WUTIP (Paolo) is estimated to be heavy (200 mm).


TY Wutip (Paolo) is expected to move west-northwest during the next 24 hours. On the forecast track, the core of Wutip (Paolo) will make landfall over Central Vietnam in between the cities of Vinh and Hue on Monday afternoon...and will traverse the rugged terrain of Laos by midnight through Tuesday early morning.

TY Wutip (Paolo) will lose strength during the next 24 hours...and will be downgraded into a Tropical Storm (TS) on Tuesday morning. Advance Intensity Forecast (AIF) shows its 1-minute maximum sustained winds decreasing to 35 km/hr on Tuesday afternoon.

The following is the summary of the 1-day forecast outlook on this system:

TUESDAY MORNING: Weakens to a Tropical Storm (TS) as it traverses the rugged terrain of Laos...about 160 km east of Vientiane, Laos [5AM OCT 01: 18.0N 104.1E @ 95kph].

*Please be reminded that the Forecast Outlook changes every 6 hours, and the Day 2 and 3 Forecast Tracks have 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.
