Typhoon Wutip (20W) – September 30th, 2013

At least 70 people have been reported missing after a typhoon caused three fishing boats to sink in the South China Sea, Chinese state media say.
Five boats carrying more than 150 people encountered strong winds from Typhoon Wutip on Sunday, Xinhua news agency says citing maritime officials.
A rescue operation is under way and reports say 14 people have been found.
The storm is expected to make landfall in central Vietnam on Monday and thousands have been evacuated there.

Track of TS 20W

Tropical Storm Maliksi (20W), located approximately 330 nautical miles southeast of Yokosuka, Japan, has accelerated north-northeastward at 32 knots over the past six hours.

Animated enhanced infrared satellite imagery shows the central convection has become greatly sheared to north-east, partially exposing the low level circulation center (LLCC). The same animation shows cold air stratocumulus clouds advecting into the LLCC from the northwest, an indication of baroclinicity.

Upper level analysis indicates TS 20W is now well north of the ridge axis in an area of very strong southwesterly vertical wind shear (30-50 knots). It is tracking along the northwest periphery of a deep-layered subtropical ridge to the east. The system is now undergoing extra-tropical transition and will become a cold core low by TAU 12.

Track of TS 20W

Tropical Storm Maliksi (20W), located approximately 30 nm south-southwest of Iwo-To, Japan, has tracked north-northwestward at 15 knots over the past six hours. Maximum significant wave height is 18 feet.

Track of TS 20W

Tropical Storm Nesat (20W), located approximately 25 nm north-northeast of Hanoi, Vietnam, has tracked west-northwestward at 07 knots over the past six hours.

Animated infrared satellite imagery depicts rapidly decaying deep convection due to land interaction.
However, an SSMIS image continues to depict a well-defined, but shallow low-level circulation center (LLCC).

The current intensity is assessed at 45 knots. Sustained surface winds reported at Hanoi are only 10-15 knots with SLP near 1004 mb.

TS 20W is forecast to continue tracking west-northwestward and should dissipate between TAU 12 and TAU 24. This track is supported by the dynamic model guidance. The system will be closely monitored for signs of regeneration.

Tropical Storm Nesat (20W) Expected to Reach Typhoon Strength, Make Landfall Over Luzon – September 24th, 2011

Track of TS 20W

As of 18:45 UTC September 24, Tropical Storm Nesat was located within 30 nautical miles of 15.0°N 132.0°E, about 730 nmi (1,350 km; 840 mi) east of Manila, Philippines.

Maximum sustained winds are 45 knots (83 km/h; 52 mph), gusting to 65 knots (120 km/h; 75 mph). Minimum central pressure is 990 mbar (hPa; 29.23 InHg), and the system is moving west at 16 knots (30 km/h; 18 mph).

Nesat is now a weak storm. However, it is expected to strengthen and become a typhoon before making landfall over northern Luzon. The area of 30 kt winds or more ranges upto 280 km (170 mi) from the center to the northeast side and 220 km (140 mi) from the center to the southwest side.
