Leave a reply

The center of Typhoon Noul hit the coast of China just to the northeast of Hong Kong on Saturday.  At 5:00 p.m. EDT on Saturday the center of Typhoon Noul was located at latitude 22.7°N and longitude 114.8°E which put the center about 60 miles (95 km) east of Hong Kong.  Noul was moving toward the northwest at 14 m.p.h. (22 km/h).  The maximum sustained wind speed was 100 m.p.h. (160 km/h) and there were wind gusts to 120 m.p.h. (195 km/h).  The minimum surface pressure was 967 mb.

Typhoon Noul continued to intensify until it made landfall on the coast of China just to the northeast of Hong Kong.  Typhoon Noul was the equivalent of a Category 2 hurricane on the Saffir-Simpson Scale at the time it made landfall.

A circular eye with a diameter of 20 miles (32 km) was at the center of Typhoon Noul when Noul made landfall.  The eye was surrounded by a ring of thunderstorms and the strongest winds were occurring in that ring of storms.  Bands of showers and thunderstorms were revolving around the core of Noul’s circulation.

The distribution of wind speeds around Typhoon Noul was fairly symmetrical.  Winds to typhoon force extended out 40 miles (65 km) from the center of Noul’s circulation.  Winds to tropical storm force extended out 140 miles (220 km) from the center of Typhoon Noul.

The Hurricane Intensity Index (HII) for Typhoon Noul was 16.5.  The Hurricane Size Index (HSI) was 14.6 and the Hurricane Wind Intensity Size Index (HWISI) was 31.1.  Typhoon Noul was capable of causing regional serious damage.

Typhoon Noul will bring strong winds and locally heavy rain to eastern Guangdong, southern Fujian, and Jiangxi.  Heavy rain is likely to cause floods in some locations.  Typhoon Noul could cause a storm surge of up to 12 feet (3.6 meters) along parts of the coast of southeastern China.

Typhoon Noul will move around the western end of a high pressure system that is over the Western North Pacific Ocean.  The high pressure system will steer Noul toward the north-northwest during the next 24 hours.  On its anticipated track, the center of Typhoon Noul will move inland over eastern Guangdong and Jiangxi.

Former Tropical Storm Noul intensified to a typhoon over the Western North Pacific Ocean east-southeast of Hong Kong on Friday.  At 11:00 p.m. EDT on Friday the center of Typhoon Noul was located at latitude 21.1°N and longitude 117.8°E which put the center about 285 miles (455 km) east-southeast of Hong Kong.  Noul was moving toward the northwest at 14 m.p.h. (22 km/h). The maximum sustained wind speed was 80 m.p.h. (130 km/h) and there were wind gusts to 100 m.p.h. (160 km/h).  The minimum surface pressure was 980 mb.

Former Tropical Storm Noul intensified to a typhoon on Friday.  The inner end of a rainband wrapped around the center of Noul’s circulation.  A small circular eye formed at the center of Typhoon Noul.  The eye was surrounded by a ring of thunderstorms and the strongest winds were occurring in that ring of storms.  Bands of showers and thunderstorms were revolving around the core of Typhoon Noul.  Storms near the core of Noul generated upper level divergence that pumped mass away from the typhoon.  The removal of mass caused the surface pressure to decrease.

The distribution of wind speed around Typhoon Noul was fairly symmetrical.  Winds to typhoon force extended out 35 miles (55 km) from the center of Noul’s circulation.  Winds to tropical storm force extended out 125 miles (200 km) from the center of Typhoon Noul.

Typhoon Noul will move through an environment favorable for intensification during the next 12 hours.  Noul will move over water where the Sea Surface Temperatures are near 30°C.  It will move under the middle of an upper level ridge that is centered over eastern China.  The upper level winds are weak near the middle of the ridge and there will be little vertical wind shear. Typhoon Noul will intensify during the next 12 hours.

Typhoon Noul will move around the southwestern part of a high pressure system that is over the Western North Pacific Ocean.  The high pressure system will steer Noul toward the northwest during the next 24 hours.  On its anticipated track, the center of Typhoon Noul will make landfall on the coast of southeastern China northeast of Hong Kong in 15 hours.

Typhoon Noul will bring strong winds and locally heavy rain to eastern Guangdong, southern Fujian, and Jiangxi.  Heavy rain is likely to cause flash floods in some locations.  Typhoon Noul could cause a storm surge of up to 12 feet (3.6 meters) along parts of the coast of southeastern China.

Tropical Storm Noul formed over the Western North Pacific Ocean east of northern Luzon on Thursday afternoon.  At 5:00 p.m. EDT on Thursday the center of Tropical Storm Noul was located at latitude 18.6°N and longitude 124.4°E which put the center about 180 miles (290 km) east of Aparri, Philippines.  Noul was moving toward the west-northwest at 17 m.p.h. (28 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 998 mb.

A low pressure system over the Western North Pacific Ocean east of northern Luzon strengthened on Thursday afternoon and the Japan Meteorological Agency designated the system as Tropical Storm Noul.

More thunderstorms were forming near the center of Tropical Storm Noul.  Thunderstorms were also occurring in bands in the western half of Noul’s circulation.  Bands in the eastern side of Tropical Storm Noul consisted primarily of showers and lower clouds.  Storm near the center of Noul began to generate upper level divergence that pumped mass away to the west of the tropical storm.  The removal of mass caused the surface pressure to decrease.

The distribution of wind speeds in Tropical Storm Noul was also asymmetrical.  Winds to tropical storm force extended out 175 miles (280 km) in the southern side of Noul’s circulation.  Winds to tropical storm force extended out 80 miles (130 km) in the northern side of Tropical Storm Noul.

Tropical Storm Noul will move through an environment favorable for intensification during the next 24 hours.  Noul will move over water where the Sea Surface Temperatures are near 30°C.  It will move under the southern part of an upper level ridge that is centered east of China.  The upper level ridge will produce northeasterly winds that will blow toward the top of Noul’s circulation.  Those winds will cause some vertical wind shear, but the wind shear will not be enough to prevent intensification.  Tropical Storm Noul will intensify during the next 24 hours.  Noul is likely to strengthen to a typhoon by the weekend.

Tropical Storm Noul will move around the southern part of a high pressure system that is over the Western North Pacific Ocean.  The high pressure system will steer Noul toward the west-northwest during the next 24 hours.  On its anticipated track, the center of Tropical Storm Noul will pass south of Taiwan on Friday.  Noul is likely to hit southeastern China during the weekend.

Tropical Storm Noul will bring gusty winds and heavy rain to northern Luzon.  Heavy rain could cause flash floods.  Noul will also bring strong winds and heavy rain to Taiwan.  Heavy rain is likely to cause flash floods.  Tropical Storm Noul is likely to be a typhoon when it hits southeastern China.

Tropical Storm Co-may Moves Inland Near Shanghai

Tropical Storm Co-may moved inland over eastern China near Shanghai on Wednesday.  At 11:00 a.m. EDT on Wednesday the center of Tropical Storm Co-may was located at latitude 31.4°N and longitude 121.1°E which put the center about 5 miles (10 km) west of Shanghai, China.  Co-may was moving toward the northwest at 7 m.p.h. (11 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 979 mb.

The center of Tropical Storm Co-may made landfall on the coast of eastern China near Shanghai on Wednesday.  Co-may was weakening as it made landfall.  Winds to tropical storm force extended out 115 miles (185 km) from the center of Co-may’s circulation.

Tropical Storm Co-may will move around the southwestern part of a high pressure system over northeastern China.  The high pressure system will steer Co-may toward the west-northwest during the next 24 hours.  On its anticipated track, the center of Tropical Storm Co-may will move inland west of Shanghai during the next 24 hours.

Tropical Storm Co-may will bring gusty winds and rain to the region around Shanghai.  Locally heavy rain could cause floods in Zhejiang and Jiangsu.

Elsewhere over the Western North Pacific Ocean, Tropical Storm Krosa was stalled southeast of Japan.  At 11:00 a.m. EDT on Wednesday the center of Tropical Storm Krosa was located at latitude 29.2°N and longitude 143.2°E which put the center about 475 miles (765 km) south-southeast of Tokyo, Japan.  Krosa was moving toward the northwest at 2 m.p.h. (3 km/h).  The maximum sustained wind speed was 45 m.p.h. (75 km/h) and there were wind gusts to 60 m.p.h. (95 km/h). The minimum surface pressure was 985 mb.

Tropical Storm Co-may Nears Eastern China

Tropical Storm Co-may neared the coast of eastern China on Tuesday.  At 11:00 a.m. EDT on Tuesday the center of Tropical Storm Co-may was located at latitude 28.9°N and longitude 123.1°E which put the center about 215 miles (345 km) south-southeast of Shanghai, China.  Co-may was moving toward the northwest at 9 m.p.h. (15 km/h).  The maximum sustained wind speed was 45 m.p.h. (75 km/h) and there were wind gusts to 60 m.p.h. (95 km/h).  The minimum surface pressure was 982 mb.

After meandering around Okinawa for several days Tropical Storm Co-may started to move toward the coast of eastern China south of Shanghai on Tuesday.  The distribution of thunderstorms in Tropical Storm Co-may was asymmetrical.  Thunderstorms were occurring in bands in the northern and western parts of Co-may’s circulation.  Bands in the eastern and southern parts of Tropical Storm Co-may consisted primarily of showers and lower clouds.

The distribution of wind speeds in Tropical Storm Co-may was also asymmetrical.  Winds to tropical storm force extended out 175 miles (280 km) in the northern side of Co-may’s circulation.  The winds in the southern half of Tropical Storm Co-may were blowing at less than tropical storm force.

Tropical Storm Co-may will move through an environment somewhat favorable for intensification during then ext 12 hours.  Co-may will move over water where the Sea Surface Temperatures are near 28°C.  It will move under the eastern side of an upper level trough that is over eastern Asia.  The upper level trough will produce southwesterly winds that will blow toward the top of Co-may’s circulation.  Those winds will cause some vertical wind shear.  The vertical wind shear will inhibit intensification but the wind shear may not be enough to prevent intensification.  Tropical Storm Co-may could intensify during the next 12 hours.

Tropical Storm Co-may will move around the western end of a high pressure system over Japan.  The high pressure system will steer Co-may toward the northwest during the next 24 hours.  On its anticipated track, the center of Tropical Storm Co-may will be near Shanghai in less than 24 hours.

Tropical Storm Co-may will bring wind and rain to the region around Shanghai.  Heavy rain could cause floods in Zhejiang and Jiangsu.

Elsewhere over the Western North Pacific Ocean, Tropical Storm Krosa was meandering south of Japan.  At 11:00 a.m. EDT on Tuesday the center of Tropical Storm Krosa was located at latitude 28.6°N and longitude 142.9°E which put the center about 500 miles (805 km) south-southeast of Tokyo, Japan.  Krosa was moving toward the north at 2 m.p.h. (3 km/h).  The maximum sustained wind speed was 60 m.p.h. (95 km/h) and there were wind gusts to 75 m.p.h. (120 km/h).  The minimum surface pressure was 980 mb.

Krosa Strengthens to a Typhoon

Former Tropical Storm Krosa strengthened to a typhoon over the Western North Pacific Ocean north of the Marianas on Sunday.  At 11:00 a.m. EDT on Sunday the center of Typhoon Krosa was located at latitude 23.3°N and longitude 145.4°E which put the center about 270 miles (435 km) north of Agrihan.  Krosa was moving toward the north-northeast at 15 m.p.h. (24 km/h).  The maximum sustained wind speed was 80 m.p.h. (130 km/h) and there were wind gusts to 100 m.p.h. (160 km/h).  The minimum surface pressure was 971 mb.

Former Tropical Storm Krosa strengthened to a typhoon north of the Marianas on Sunday.  The inner end of a rainband wrapped around the northern and western sides of the center of Typhoon Krosa.  Other bands of showers and thunderstorms were revolving around the center of Krosa’s circulation.  Storms near the center of Krosa generated upper level divergence that pumped mass away from the typhoon.  The removal of mass caused the surface pressure to decrease.

The circulation around Typhoon Krosa became more symmetrical on Sunday.  Winds to typhoon force extended out 45 miles (75 km) from the center of Krosa’s circulation.  Winds to tropical storm force extended out 195 miles (315 km) from the center of Typhoon Krosa.

Tropical Storm Krosa will move through and environment somewhat favorable for intensification during the next 24 hours.  Krosa will move over water where the Sea Surface Temperatures are near 28°C.  It will move under the eastern side of an upper level low centered southeast of Japan.  The upper level low will produce southerly winds that will blow toward the top of Krosa’s circulation.  Those winds will cause some vertical wind shear. The vertical wind shear will inhibit intensification, but the wind shear may not be enough to prevent intensification. Typhoon Krosa could intensify during the next 24 hours.

Typhoon Krosa will move around the western end of a high pressure system over the Western North Pacific Ocean.  The high pressure system will steer Krosa toward the north during the next 24 hours. On its anticipated track, the center of Typhoon Krosa will pass east of Iwo To.

Elsewhere over the Western North Pacific Ocean, former Tropical Storm Co-may strengthened back to a tropical storm near Okinawa.  At 11:00 a.m. EDT on Sunday the center of Tropical Storm Co-may was located at latitude 26.8°N and longitude 127.6°E which put the center about 15 miles (25 km) northeast of Okinawa.  Co-may was moving toward the west at 16 m.p.h. (26 km/h).  The maximum sustained wind speed was 45 m.p.h. (75 km/h) and there were wind gusts to 60 m.p.h. (95 km/h).  The minimum surface pressure was 986 mb.

Tropical Storm Co-may Drops Heavy Rain on Taiwan

Tropical Storm Co-may dropped heavy rain on Taiwan on Friday.  At 11:00 a.m. EDT on Friday the center of Tropical Storm Co-may was located at latitude 22.8°N and longitude 123.9°E which put the center about 200 miles (320 km) southeast of Taipei, Taiwan.  Co-may was moving toward the northeast at 41 m.p.h. (67 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.

Even though the center of Tropical Storm Co-may was passing east of Taiwan, bands in the western side of Co-may’s circulation were dropping heavy rain on parts of southern Taiwan.

Heavy Rain Advisories were in effect for parts of southern Taiwan.

Strong vertical wind shear was causing Tropical Storm Co-may to weaken as it passed east of Taiwan on Friday.  An upper level low centered over eastern China was producing strong southwesterly winds that were blowing toward the top of Co-may’s circulation.  Those winds were causing strong vertical wind shear.  The strong vertical wind shear was causing Tropical Storm Co-may to weaken.

The distribution of wind speeds in Tropical Storm Co-may became asymmetrical when Co-may weakened.  Winds to tropical storm force extended out 115 miles (185 km) in the southeastern quadrant of Co-may’s circulation.  The winds in the other parts of Tropical Storm Co-may were blowing at less than tropical storm force.

Tropical Storm Co-may will move through an environment that will be unfavorable for intensification during the next 24 hours.  Co-may will move over water where the Sea Surface Temperatures are near 29°C.  However, it will move under the eastern side of the upper level low that is centered over eastern China.  The upper level low will continue to produce strong southwesterly winds that will blow toward the top of Co-may’s circulation.  Those winds will cause strong vertical wind shear.  The strong vertical wind shear will cause Tropical Storm Co-may to weaken to a tropical depression during the next 24 hours.

The upper low over eastern China will steer Tropical Storm Co-may quickly toward the northeast during the next 24 hours.  On its anticipated track, Tropical Storm Co-may will move across the southern Ryukyu Islands.

Tropical Storm Co-may will bring gusty winds and locally heavy rain to the southern Ryukyu Islands.

Elsewhere over the Western North Pacific Ocean, former Tropical Storm Francisco weakened to a tropical depression north of Taiwan and Tropical Storm Krosa strengthened gradually west of the Marianas.

At 11:00 a.m. EDT on Friday the center of Tropical Depression Francisco was located at latitude 26.2°N and longitude 121.4°E which put the center about 75 miles (120 km) north of Taipei, Taiwan.  Francisco was moving toward the west-southwest at 11 m.p.h. (17 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 993 mb.

At 11:00 a.m. EDT on Friday the center of Tropical Storm Krosa was located at latitude 18.0°N and longitude 143.8°E which put the center about 225 miles (365 km) northwest of Saipan.  Krosa was moving toward the northeast at 7 m.p.h. (11 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 994 mb.

Co-may Strengthens to a Typhoon

Former Tropical Storm Co-may strengthened to a typhoon over the Western North Pacific Ocean west of northern Luzon on Thursday.  At 5:00 a.m. EDT on Thursday the center of Tropical Storm Co-may was located at latitude 16.2°N and longitude 119.6°E which put the center about 65 miles (105 km) west of Baguio, Philippines.  Co-may was moving toward the east at 9 m.p.h. (15 km/h).  The maximum sustained wind speed was 80 m.p.h. (130 km/h) and there were wind gusts to 100 m.p.h. (160 km/h).  The minimum surface pressure was 974 mb.

Former Tropical Storm Co-may strengthened to a typhoon as it approached the coast of northwestern Luzon on Thursday.  Numerous thunderstorms were occurring near the center of Co-may’s circulation.  Bands of showers and thunderstorms were revolving around the center of Typhoon Co-may.  Storms near the center of Co-may generated upper level divergence that pumped mass away from the typhoon.  The removal of mass caused the surface pressure to decrease.

The circulation around Typhoon Co-may was small.  Winds to typhoon force extended out 20 miles (30 km) from the center of Co-may’s circulation.  Winds to tropical storm force extended out 100 miles (160 km) from the center of Typhoon Co-may.

Typhoon Co-may will move through an environment somewhat favorable for intensification during the next few hours.  Co-may will move over water where the Sea Surface Temperatures are near 29°C.  It will move under the southeastern side of an upper level low that is centered over the east coast of China.  The upper level low will produce southwesterly winds that will blow toward the top of Co-may’s circulation.  Those winds will cause moderate vertical wind shear. The vertical wind shear will inhibit intensification, but the wind shear may not be enough to prevent intensification. Typhoon Co-may could intensify a little more during the next few hours.

Typhoon Co-may will get pulled toward the northeast by the much larger circulation around Tropical Storm Francisco.  On its anticipated track, Typhoon Co-may will make landfall on the coast of northern Luzon near Bolinao in a few hours.  The center of Co-may will pass just west of Baguio.  The center will pass south of Vigan.

Typhoon Co-may will bring strong winds and locally heavy rain to northern Luzon.  Heavy rain could cause flash floods and mudslides.  Typhoon Co-may is likely to cause widespread outages of electricity in northern Luzon.  Co-may could also cause a storm surge of up to 7 feet (2 meters) along the coast of northwestern Luzon.

Elsewhere over the Western North Pacific Ocean, the center of Tropical Storm Francisco was approaching  Okinawa.  At 5:00 a.m. EDT on Thursday the center of Tropical Storm Francisco was located at latitude 25.2°N and longitude 127.4°E which put the center about 110 miles (175 km) south of Okinawa.  Francisco was moving toward the north at 12 m.p.h. (19 km/h).  The maximum sustained wind speed was 45 m.p.h. (75 km/h) and there were wind gusts to 60 m.p.h. (95 km/h).  The minimum surface pressure was 987 mb.

(15 km/h).  The maximum sustained wind speed was 45 m.p.h. (75 km/h) and there were wind gusts to 60 m.p.h. (95 km/h).  The minimum surface pressure was 992 mb.

A low pressure system over the Western North Pacific Ocean west of Luzon strengthened on Wednesday and the Japan Meteorological Agency designated the system as Tropical Storm Co-may.

The circulation around Tropical Storm Co-may was organizing quickly.  More thunderstorms formed near the center of Co-may’s circulation.  Bands of showers and thunderstorms were revolving around the center of Tropical Storm Co-may.  Storms near the center of Co-may generated upper level divergence that pumped mass away from the tropical storm.  The removal of mass caused the surface pressure to decrease.

The strongest winds were occurring in the western side of Tropical Storm Co-may.  Winds to tropical storm force extended out 100 miles (160 km) in the western half of Co-may’s circulation.  The winds in the eastern side of Tropical Storm Co-may were blowing at less than tropical storm force.

Tropical Storm Co-may will move through an environment favorable for intensification during the next 24 hours.  Co-may will move over water where the Sea Surface Temperatures are near 29°C.  It will move under the southeastern side of an upper level low that is centered east of Taiwan.  The upper level low will produce southwesterly winds that will blow toward the top of Co-may’s circulation.  Those winds will cause some vertical wind shear.  The vertical wind shear will inhibit intensification, but the wind shear will not be enough to prevent intensification.  Tropical Storm Co-may will intensify during the next 24 hours.  Co-may could strengthen to a typhoon on Thursday.

Tropical Storm Co-may will get pulled toward the northeast by the much larger circulation around Tropical Storm Francisco.  On its anticipated track, Tropical Storm Co-may will approach northern Luzon in 24 hours.

Tropical Storm Co-may could be a typhoon when it approaches the coast of northwestern Luzon.  Co-may will bring strong winds and locally heavy rain to northern Luzon.  Heavy rain could cause flash floods and mudslides.  Tropical Storm Co-may is likely to cause widespread outages of electricity in northern Luzon.  Co-may could also cause a storm surge of up to 7 feet (2 meters) along the coast of northwestern Luzon.

Elsewhere over the Western North Pacific Ocean, Tropical Storm Francisco strengthened a little as it moved toward the southern Ryukyu Islands.  At 11:00 a.m. EDT on Wednesday the center of Tropical Storm Francisco was located at latitude 22.5°N and longitude 129.1°E which put the center about 325 miles (525 km) south-southeast of Okinawa.  Francisco was moving toward the northwest at 7 m.p.h. (11 km/h).  The maximum sustained wind speed was 45 m.p.h. (75 km/h) and there were wind gusts to 60 m.p.h. (95 km/h).  The minimum surface pressure was 994 mb.
