Strengthening Typhoon Nesat moved nearer to Taiwan on Friday.   At 5:00 p.m. EDT on Friday the center of Typhoon Nesat was located at latitude 22.0°N and longitude 123.3°E which put it about 275 miles (440 km) south-southeast of Taipei, Taiwan.  Nesat was moving toward the west-northwest at 10 m.p.h. (16 km/h).  The maximum sustained wind speed was 85 m.p.h. (135 km/h) and there were wind gusts to 105 m.p.h. (170 km/h).  The minimum surface pressure was 973 mb.

Typhoon Nesat has a very well organized circulation.  A ring of thunderstorms almost completely surrounds the eye.  There is a small gap in the ring on the northeastern rim of the eye.  Numerous additional bands of showers and thunderstorms are occurring in the southern half of the circulation.  There are fewer bands of showers and thunderstorms in the northern part of the circulation.  Thunderstorms in the core of Typhoon Nesat are producing upper level divergence which is pumping out mass.  Winds to typhoon force extend out about 40 miles (65 km) from the center of circulation.  Winds to tropical storm force extend out about 145 miles (230 km) from the center.

Typhoon Nesat will be moving through an environment favorable for intensification until it reaches Taiwan.  Nesat will move over water where the Sea Surface Temperature is near 30°C.  An upper level ridge centered west of Japan is producing east-northeasterly winds which are blowing toward the top of the circulation.  Those winds are causing some vertical wind shear, but they are not strong enough to keep Typhoon Nesat from strengthening.  Typhoon Nesat is likely to intensify for another 12-18 hours until it reaches Taiwan.  When it Nesat reaches Taiwan, the mountains will disrupt the circulation.

Typhoon Nesat is being steered toward the west-northwest by a subtropical ridge to its north.  A general west-northwesterly or northwesterly motion is expected to continue until Nesat makes landfall in Taiwan.  On its anticipated track Typhoon Nesat will make landfall on the east coast of Taiwan in 12 to 18 hours.  Neast will bring strong winds and heavy rain to Taiwan.  The heavy rain is likely to cause flash floods in the mountains.
