for Saturday, 28 September 2013 [9:40 PM PhT]



Issued at: 6:15 PM PhT (10:15 GMT) Saturday 28 September 2013

Tropical Storm WUTIP (PAOLO) intensifies to near-typhoon status as it starts drifting west-northwest during the past 3 hours...could become a Typhoon later tonight or early Sunday. This cyclone remains a threat to Central Vietnam and Hainan Island.

Meanwhile, Tropical Disturbance (LPA) 95W remains scattered and disorganized as it drifts northward across the Western Pacific Ocean, outside of Philippine Area of Responsibility (PAR). Its center was located about 590 km NNW of Yap Island or 1,185 km East of Bicol Region (14.1N Lat 135.4E Lon)...with maximum winds of 30 km/hr near the center...currently moving NNW at 19 kph. Various forecast models suggest this system could become a Tropical Cyclone within the next 24 to 48 hours with a north to north-northeast track across the open seas of the Western Pacific Ocean...and is not 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).

The 24-hour rainfall accumulation to the north and near the center of WUTIP (Paolo) is estimated to be extreme (400 mm).


TS Wutip (Paolo) is expected to move west-southwest to west during the next 24 hours...with a turn to the west-northwest through 48 hours. On the forecast track, the core of Wutip (Paolo) will be over the western part of the South China Sea on Sunday afternoon...and will be just along the coast of Central Vietnam near Hue City on Monday afternoon.

TS Wutip (Paolo) will continue to gain strength during the next 24 to 48 hours...and could become a Typhoon (TY) later tonight or early Sunday. Advance Intensity Forecast (AIF) shows its 1-minute maximum sustained winds increasing to 160 km/hr by early Monday morning.
