TYPHOON WUTIP (PAOLO) UPDATE NUMBER 005
Issued at: 7:30 AM PhT (23:30 GMT) Sunday 29 September 2013
WUTIP (PAOLO) becomes a Typhoon (TY) as it continues to drift slowly westward across the South China Sea...threat to Central Vietnam increases.
Meanwhile, Tropical Disturbance (LPA) 95W has reorganized over the southern portion of the Philippine Sea...just along the eastern boundary of the Philippine Area of Responsibility (PAR). Its center was located about 1,040 km east-southeast of Borongan City, Samar (11.0N Lat 134.9E Lon)...with maximum winds of 35 km/hr near the center...currently quasi-stationary during the past 12 hours. Various forecast models suggest this system could become a Tropical Cyclone within the next 24 to 48 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 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).
