Leave a reply

Tropical Storm Danas dropped rain on eastern China on Tuesday.  At 5:00 p.m. EDT on Tuesday the center of Tropical Storm Danas was located at latitude 27.6°N and longitude 120.3°E which put the center about 50 miles (80 km) southwest of Wenzhou, China.  Danas was moving toward the west-southwest at 6 m.p.h. (10 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 986 mb.

The center of Tropical Storm Danas made landfall on the east coast of China just to the south of Wenzhou on Tuesday.  The maximum sustained wind speed was 40 m.p.h. (65 km/h) at the time of landfall.  Winds to tropical storm force extended out 120 miles (195 km) from the center of Danas’ circulation.

Tropical Storm Danas will move around the southern side of a high pressure system over eastern Asia.  The high pressure system will steer Danas toward the southwest during the next 24 hours.  On its anticipated track, Tropical Storm Danas will move farther inland over eastern China.

Tropical Storm Danas will weaken gradually as it moves inland over eastern China.  The heaviest rain will be produced by bands in the southern side of Danas’ circulation.  Bands in the northern side of Tropical Storm Danas will consist primarily of showers and lower clouds.

Tropical Storm Danas will drop heavy rain over parts of Zhejiang.  Heavy rain could cause floods in some locations.

The strongest winds will occur in the eastern side of Danas’ circulation which will be over the East China Sea.  Most of the winds over land will be at less than tropical storm force.

Tropical Storm Danas was nearing eastern China on Monday evening.  At 11:00 p.m. EDT on Monday the center of Tropical Storm Danas was located at latitude 28.1°N and longitude 122.0°E which put the center about 80 miles (130 km) east of Wenzhou, China and about 50 miles (80 km) southeast of Taizhou, China.  Danas was moving toward the north at 6 m.p.h. (10 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.

Even though Tropical Storm Danas was over the East China Sea on Monday, Danas’ circulation was still disrupted from the affects of its passage over Taiwan on Sunday.  The distribution of thunderstorms in Tropical Storm Danas was asymmetrical.  Thunderstorms were occurring in bands in the southern part of Danas’ circulation.  Bands in the northern side of Tropical Storm Danas consisted primarily of showers and lower clouds.

Winds to tropical storm force extended out 90 miles (145 km) from the center of Tropical Storm Danas.

Tropical Storm Danas will move through an environment that will be somewhat favorable for intensification during the next few hours. Danas will move over water where where the Sea Surface Temperatures are near 29°C.  It will move under the middle of an upper level ridge over East China Sea.  The upper level winds are weak near the middle of the ridge and there will be little vertical wind shear.  Even though Tropical Storm Danas will move through a somewhat favorable environment, Danas may not intensify because of the disruption of its circulation during the passage over Taiwan.

Tropical Storm Danas will move around the southern side of a high pressure system over eastern Asia.  The high pressure system will steer Danas toward the west during the next 24 hours.  On its anticipated track, Tropical Storm Danas will move over eastern China in a few hours.

The center of Tropical Storm Danas is likely to make landfall in China between Taizhou and Wenzhou.  Danas will bring gusty winds and locally heavy rain to Zhejiang.  Heavy rain could cause floods in some locations.

Typhoon Danas brought strong winds and heavy rain to Taiwan on Sunday.  Danas weakened to a tropical storm after it moved across Taiwan.  At 11:00 p.m. EDT on Sunday the center of Tropical Storm Danas was located at latitude 25.9°N and longitude 121.6°E which put the center about 30 miles (50 km) north-northwest of Taipei, Taiwan.  Danas was moving toward the north-northeast at 22 m.p.h. (35 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 989 mb.

The center of former Typhoon Danas moved north-northeast across western Taiwan on Sunday.  Danas produced strong winds and heavy rains as it moved across Taiwan.  The heaviest rain fell in parts of southern Taiwan and in a few mountain areas where the winds were blowing up the slopes.  The Central Weather Administration’s radar estimated that up to a foot (300 mm) of rain fell in some locations.

Former Typhoon Danas weakened to a tropical storm as it moved across western Taiwan.  The center of Danas’ circulation moved over the East China Sea on Sunday night.  Thunderstorms were still occurring near the center of Tropical Storm Danas.  Thunderstorms were also still occurring in bands revolving around the center of Danas’ circulation.

The distribution of wind speeds in Tropical Storm Danas was asymmetrical.  Winds to tropical storm force extended out 175 miles (280 km) in the eastern side of Danas’ circulation.  Winds to tropical storm force extended out 80 miles (130 km) in the western side of Danas.

Tropical Storm Danas will move through an environment that will be somewhat favorable for intensification during the next 24 hours.  Danas will move over water where where the Sea Surface Temperatures are near 29°C.  It will move under the eastern side of an upper level low over eastern China.  The upper level low will produce southwesterly winds that will blow toward the top of Danas’ circulation.  Those winds will cause moderate vertical wind shear.  The wind shear will inhibit intensification, but the shear may not be enough to prevent intensification.  Tropical Storm Danas could intensify during the next 24 hours.

The upper level low over eastern China will steer Tropical Storm Danas toward the north-northeast during the next 24 hours.  On its anticipated track, Danas will move away from Taiwan.  Tropical Storm Danas could approach the east coast of China in 36 hours.

Wind speeds will decrease in Taiwan when Tropical Storm Danas moves farther away.  Heavy rain should also diminish as the circulation around Danas moves away from Taiwan.

Elsewhere over the Western North Pacific Ocean, Tropical Storm Mun weakened east of Japan.  At 11:00 p.m. EDT on Sunday the center of Tropical Storm Mun was located at latitude 35.5°N and longitude 148.7°E which put the center about 520 miles (835 km) east of Tokyo, Japan.  Mun was moving toward the north-northwest at 12 m.p.h. (19 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 986 mb.

Tropical Storm Chantal strengthened a little as it approached the Carolinas on Saturday evening.  Even though Chantal was a little stronger, the distribution of thunderstorms was still asymmetrical.  Thunderstorms were occurring in bands in the eastern side of Chantal’s circulation.  Bands in the western part of Tropical Storm Chantal consisted primarily of showers and lower clouds.  Storms east of the center of Chantal’s circulation generated upper level divergence that pumped mass away to the north and east of the tropical storm.  The removal of mass caused the surface pressure to decrease slowly.

The distribution of wind speeds in Tropical Storm Chantal was also asymmetrical. The strongest winds were occurring in bands of thunderstorms in the northeastern part of Chantal’s circulation.  Winds to tropical storm force extended out 140 miles (220 km) in the eastern side of Tropical Storm Chantal.  Winds to tropical storm force extended out 35 miles (55 km) in the western side of Chantal.

Tropical Storm Chantal will move through an environment that will be somewhat favorable for intensification during the next few hours.  Chantal will move over water where where the Sea Surface Temperatures are near 28°C.  It will move under the northeastern part of an upper level low over the southeastern U.S.  The upper level low will produce southwesterly winds that will blow toward the top of Chantal’s circulation.  Those winds will cause moderate vertical wind shear.  The wind shear will inhibit intensification, but the shear may not be enough to prevent intensification.  Tropical Storm Chantal could intensify a little more during the next few hours.

The upper level low over the southeastern U.S. will steer Tropical Storm Chantal toward the north during the next 24 hours.  On its anticipated track, Tropical Storm Chantal will make landfall on the coast near the border between South Carolina and North Carolina in a few hours.

Tropical Storm Chantal will bring strong winds and locally heavy rain to eastern South Carolina and to eastern North Carolina.  The heaviest rain and strongest winds will occur in the northeastern part of Chantal’s circulation.  Heavy rain could cause flash floods in some locations.  Tropical Storm Chantal could cause a storm surge of up to four feet (one meter).  Chantal will also bring high waves to the coast. The waves could cause beach erosion.

Former Tropical Storm Danas intensified to a typhoon over the South China Sea southwest of Taiwan on Saturday.  At 5:00 p.m. EDT on Saturday the center of Typhoon Danas was located at latitude 21.4°N and longitude 118.3°E which put the center about 170 miles (275 km) southwest of Kaohsiung, Taiwan.  Danas was moving toward the north-northeast at 4 m.p.h. (6 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 977 mb.

Former Tropical Storm Dana intensified to a typhoon over the South China Sea southwest of Taiwan on Saturday.  The distribution of thunderstorms in Typhoon Danas became more symmetrical as Danas intensified.  More thunderstorms developed near the center of Danas’ circulation.  More thunderstorms also formed in bands revolving around the center of Typhoon Danas.  Storms near the center of Danas generated upper level divergence that pumped mass away from the typhoon.  The removal of mass caused the surface pressure to decrease.

The size of the circulation around Typhoon Danas increased as Danas intensified.  Winds to typhoon force extended out 35 miles (55 km) from the center of Danas’ circulation.  Winds to tropical storm force extended out 140 miles (220 km) from the center of Typhoon Danas.

Typhoon Danas will move through an environment mostly favorable for intensification during the next 18 hours.  Danas will move over water where where the Sea Surface Temperatures are near 29°C.  It will move under the western part of an upper level ridge over that is centered east of Taiwan.  The upper level ridge will produce southwesterly winds that will blow toward the top of Danas’ circulation.  Those winds will cause some vertical wind shear.  The wind shear will inhibit intensification, but the shear will not be enough to prevent intensification. Typhoon Danas will intensify during the next 18 hours.  Danas could intensify rapidly at times.

Typhoon Danas will move around the western end of a high pressure system over the Western North Pacific Ocean.  The high pressure system will steer Danas toward the north-northeast during the next 24 hours.  On its anticipated track, Typhoon Danas will approach the west coast of Taiwan in 18 hours.

Typhoon Danas will bring strong winds and locally heavy rain to Taiwan. Heavy rain is likely to cause flash floods. Typhoon Danas could also cause a storm surge of up to 10 feet (3 meters) along parts of the coast of Taiwan.

A Tropical Storm Watch is in effect for the portion of the coast from Edisto Beach to Little River Inlet, South Carolina.

A low pressure system over the Atlantic Ocean off the Southeast U.S. coast strengthened on Friday afternoon.  Based on satellite images and data collected by a U.S. Air Force Reserve Hurricane Hunter aircraft, the U.S. National Hurricane Center designated the system as Tropical Depression Three.

More thunderstorms formed near the center of Tropical Depression Three.  Thunderstorms also developed in bands in the northern and eastern parts of the tropical depression.  Storms near the center of circulation began to generate upper level divergence that pumped mass away to the north and east of the tropical depression.

Tropical Depression Three will move through an environment that will be somewhat favorable for intensification during the next 24 hours.  Tropical Depression Three will move over water where where the Sea Surface Temperatures are near 29°C.  It will move under the eastern side of an upper level trough over the southeastern U.S.  The upper level trough will produce southwesterly winds that will blow toward the top of the tropical depression.  Those winds will cause moderate vertical wind shear.  The wind shear will inhibit intensification, but the shear will not be enough to prevent intensification.  Tropical Depression Three is likely to intensify to a tropical storm during the next 24 hours.

The upper level trough over the Southeastern U.S. will steer Tropical Depression Three toward the north-northwest during the next 24 hours.  On its anticipated track, Tropical Depression Three will move toward the coast of South Carolina.  It could make landfall early on Sunday.

Tropical Depression Three is likely to strengthen to a tropical storm before it makes landfall.  It will bring winds and locally heavy rain.  Heavy rain could cause flash floods in some locations.
