Leave a reply

Tropical Depression Pulasan moved near Shanghai on Thursday.  At 11:00 a.m. EDT on Thursday the center of Tropical Depression Pulasan was located at latitude 30.8°N and longitude 121.6°E which put the center about 50 miles (80 km) south-southeast of Shanghai, China.  Pulasan was moving toward the northwest at 15 m.p.h. (24 km/h).  The maximum sustained wind speed was 35 m.p.h. (55 km/h) and there were wind gusts to 45 m.p.h. (75 km/h).  The minimum surface pressure was 998 mb.

Former Tropical Storm Pulasan weakened to a tropical depression as it approached Shanghai on Thursday.  Pulasan brought gusty winds and heavy rain to the region around Shanghai.

The distribution of thunderstorms in Tropical Depression Pulasan was asymmetrical.  Thunderstorms were occurring in bands in the northern side of Pulasan’s circulation.  The bands in the southern side of the circulation consisted primarily of showers and lower clouds.

Tropical Depression Pulasan will move around the western end of a high pressure system over the Western North Pacific Ocean.  The high pressure system will steer Pulasan toward the north-northwest during the next 24 hours.  On its anticipated track, Tropical Depression Pulasan will move north of Shanghai.

Tropical Storm Pulasan will continue to bring gusty winds and locally heavy rain to the area north of Shanghai during the next 12 hours.  Heavy rain could cause floods in some locations.

Tropical Storm Pulasan brought gusty winds and rain to Okinawa on Wednesday.  At 5:00 p.m. EDT on Wednesday the center of Tropical Storm Pulasan was located at latitude 27.5°N and longitude 126.9°E which put the center about 35 miles (55 km) north of Okinawa.  Pulasan was moving toward the northwest at 15 m.p.h. (24 km/h).  The maximum sustained wind speed was 50 m.p.h. (80 km/h) and there were wind gusts to 65 m.p.h. (105 km/h).  The minimum surface pressure was 998 mb.

Tropical Storm Pulasan brought gusty winds and locally heavy rain to parts of Okinawa on Wednesday.  A weather station in Oku, Japan reported 5.04 inches (128 mm) of rain.  A weather station in Yoronjima Island reported 3.66 inches (93 mm) of rain.

The distribution of thunderstorms in Tropical Storm Pulasan was asymmetrical.  Thunderstorms were occurring in bands in the northern and eastern sides of Pulasan’s circulation.  Bands in the southern and western sides of Tropical Storm Pulasan consisted primarily of showers and lower clouds.

The distribution of wind speeds in Tropical Storm Pulasan was also asymmetrical.  Winds to tropical storm force extended out 320 miles (520 km) in the northwestern, northeastern and southeastern quadrants of Pulasan’s circulation.  The winds in the southwestern quadrant of Tropical Storm Pulasan were blowing at less than tropical storm force,

Tropical Storm Pulasan will move through an environment marginally favorable for intensification during the next 24 hours.  Pulasan will move over water where the Sea Surface Temperatures are near 30°C.  It will move under the northern side of a large upper level low centered southeast of China.  The upper level low will produce easterly winds that will blow toward the top of Pulasan’s circulation.  Those winds will cause strong vertical wind shear. The strong wind shear will inhibit intensification.  Tropical Storm Pulasan could maintain its intensity during the next 24 hours if the wind shear does not get any stronger.  Pulasan will weaken if the vertical wind shear increases.

Tropical Storm Pulasan will move around the northern side of a large counterclockwise circulation southeast of China that is sometimes called a monsoon gyre.  The large counterclockwise circulation will steer Pulasan quickly toward the west-northwest during the next 24 hours.  On its anticipated track, Tropical Storm Pulasan will be near Shanghai, China in 24 hours.

Tropical Storm Pulasan will bring gusty winds and locally heavy rain to the region around Shanghai.  Flooding is still occurring from the recent passage of Typhoon Bebinca over the same area.  Additional heavy rain will make flooding worse.

Tropical Storm Pulasan formed over the Western North Pacific Ocean southeast of the Ryukyu Islands on Monday.  At 11:00 p.m. EDT on Monday the center of Tropical Storm Pulasan was located at latitude 19.3°N and longitude 137.8°E which put the center about 450 miles (725 km) south-southwest of Iwo To.  Pulasan was moving toward the west-northwest at 22 m.p.h. (35 km/h).  The maximum sustained wind speed was 40 m.p.h. (65 km/h) and there were wind gusts to 50 m.p.h. (80 km/h).  The minimum surface pressure was 997 mb.

The circulation around Tropical Storm Pulasan was very large, but there were not many thunderstorms present.  Bands revolving around the center of Pulasan’s circulation consisted primarily of showers and lower clouds.  Thunderstorms were occurring in a band in the far eastern periphery of Tropical Storm Pulasan.  Thunderstorms were also occurring in a band in the far southern periphery of Pulasan’s circulation.

The circulation around Tropical Storm Pulasan was very large, but the distribution of wind speeds was asymmetrical.  Winds to tropical storm force extended out 265 miles (425 km) in the eastern side of Pulasan’s circulation.  The winds in the western side of Tropical Storm Pulasan were blowing at less than tropical storm force.

Tropical Storm Pulasan will move through an environment marginally favorable for intensification during the next 24 hours.  Pulasan will move over water where the Sea Surface Temperatures are near 30°C.  It will move under the eastern side of a large upper level low centered east of Taiwan.  The upper level low will produce southwesterly winds that will blow toward the top of Pulasan’s circulation.  Those winds will cause strong vertical wind shear.  The strong wind shear will inhibit intensification.  Tropical Storm Pulasan could intensify a little during the next 24 hours if the wind shear does not get any stronger.

Tropical Storm Pulasan will move around the northern side of a large counterclockwise circulation sometimes called a monsoon gyre.  The large counterclockwise circulation will steer Pulasan quickly toward the west-northwest during the next 36 hours.  On its anticipated track Tropical Storm Pulasan will be near the Ryukyu Islands in 36 hours.

Tropical Storm Pulasan will bring gusty winds and locally heavy rain to the Ryukyu Islands.  Heavy rain could cause flash floods in some locations.

Elsewhere, former Typhoon Bebinca weakened to a tropical depression over eastern China.  At 11:00 p.m. EDT on Monday the center of Tropical Depression Bebinca was located at latitude 32.0°N and longitude 117.0°E which put the center about 100 miles (160 km) west of Nanjing, China.  Bebinca was moving toward the west-northwest at 12 m.p.h. (19 km/h).  The maximum sustained wind speed was 35 m.p.h. (55 km/h) and there were wind gusts to 45 m.p.h. (75 km/h).  The minimum surface pressure was 1004 mb.
