TS WUTIP (PAOLO) Update #002


for Friday, 27 September 2013 [8:10 PM PhT]


Issued at: 7:00 PM PhT (11:00 GMT) Friday 27 September 2013

20W (PAOLO) has intensified into a Tropical Storm...internationally named as WUTIP (Macao name of butterfly) as it accelerated and moved out from the Philippine Area of Responsibility (PAR). It is likely to threaten Vietnam early next week.

This storm will slightly enhance the Southwest Monsoon (Hanging Habagat) - bringing mostly cloudy and breezy conditions with occasional slight to moderate to sometimes heavy rains or thunderstorms across the western sections of Central Luzon, Metro Manila, MiMaRoPa, Spratly Islands and CaLaBaRZon tonight. The threat of flash floods and landslides are likely in hazard-prone areas especially along river banks and mountain slopes of the affected areas. Residents are advised to take necessary precautions.

Meanwhile, Tropical Disturbance (LPA) 95W continues to consolidate. Its center was located about 505 km ENE of Surigao City or 515 km ESE of Borongan, Samar (10.0N Lat 134.0E Lon)...with maximum winds of 35 km/hr near the center...currently moving WSW at 22 kph. Various forecast models suggest this system could become a Tropical Cyclone within the next 24 to 48 hours with a northward track across the Philippine Sea...and is not yet a threat to the Philippines. This disturbance has a medium chance (30-50%) 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 pm today, the center of TS WUTIP (Paolo) was located over the West Philippine Sea...about 540 km northwest of Subic Bay, Zambales or 815 km east-northeast of Da Nang, Vietnam...currently moving west with increasing forward speed of 20 km/hr towards Vietnam.

Maximum Sustained Winds (1-min. avg) are at 65 km/hr near the center with higher gusts. Wutip (Paolo) has grown into 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 (250 mm).


TS WUTIP (Paolo) is expected to continue moving west during the next 24 hours...with a turn to the west-southwest and back to west through 48 hours. On the forecast track, the core of WUTIP (Paolo) will be moving over the western part of the South China Sea, east of Central Vietnam thru Sunday.

TS WUTIP (Paolo) will further gain strength during the next 24 to 48 hours...and could become a Typhoon (TY) on Sunday afternoon. Advance Intensity Forecast (AIF) shows its 1-minute maximum sustained winds increasing to 120 km/hr on Sunday afternoon.

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

SATURDAY AFTERNOON: Intensifies further as a TS as it moves across the central part of the South China Sea...about 700 km west-northwest of Dagupan City, Pangasinan [5PM SEP 28: 16.9N 114.2E @ 85kph].

*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.
