Former Tropical Storm Podul strengthened to a typhoon over the Western North Pacific Ocean east-southeast of Taiwan on Monday.  At 5:00 p.m. EDT on Monday the center of Typhoon Podul was located at latitude 20.8°N and longitude 128.6°E which put the center about 510 miles (825 km) east-southeast of Taipei, Taiwan.  Podul was moving toward the west at 16 m.p.h. (26 km/h).  The maximum sustained wind speed was 75 m.p.h. (120 km/h) and there were wind gusts to 90 m.p.h. (145 km/h).  The minimum surface pressure was 984 mb.

The circulation around Typhoon Podul became more symmetrical on Monday.  A circular eye appeared at the center of Podul’s circulation.  The eye was surrounded by a broken ring of thunderstorms.  The strongest winds were occurring in that broken ring of storms.  Bands of showers and thunderstorms were revolving around the center of Typhoon Podul.  Storms near the center of Podul generated upper level divergence that pumped mass away from the typhoon.  The removal of mass caused the surface pressure to decrease.

The strongest winds were occurring in the eastern side of Typhoon Podul.  Winds to typhoon force extended out 35 miles (55 km) in the eastern side of Podul’s circulation.  Winds to tropical storm force extended out 105 miles (165 km) from the center of Typhoon Podul.

Typhoon Podul will move through an environment that will be somewhat favorable for intensification during the next 24 hours.  Podul will move over water where the Sea Surface Temperatures are near 29°C.  However, an upper level ridge over eastern China and Japan will produce northeasterly winds that will blow toward the top of Podul’s circulation.  Those winds will cause moderate vertical wind shear.  The vertical wind shear will inhibit intensification, but the shear may not be enough to prevent intensification.  Typhoon Podul could intensify during the next 24 hours if the wind shear does not get any stronger.

Typhoon Podul will move around the southern side of a high pressure system that is south of Japan.  The high pressure system will steer Podul toward the west-northwest during the next 24 hours.  On its anticipated track, Typhoon Podul will approach Taiwan in 24 hours.

Typhoon Podul will bring strong winds and heavy rain to Taiwan.  Heavy rain is likely to cause flash floods in some locations.
