Typhoon Molave Makes Landfall in Vietnam

Typhoon Molave made landfall on the central coast of Vietnam on Tuesday night. At 11:00 p.m. EDT on Tuesday the center of Typhoon Molave was located at latitude 15.1°N and longitude 109.1°E which put it about 10 miles (15 km) east of Quang Ngai, Vietnam. Molave was moving toward the west-northwest at 18 m.p.h. (30 km/h). The maximum sustained wind speed was 105 m.p.h. (165 km/h) and there were wind gusts to 125 m.p.h. (200 km/h). The minimum surface pressure was 957 mb.

Typhoon Molave made landfall on the coast of Vietnam near Quang Ngai on Tuesday night. Winds to typhoon force extended out 45 miles (75 km) from the center of Molave. Winds to tropical storm force extended out 150 miles (240 km) from the center of circulation. The Hurricane Intensity Index (HII) for Typhoon Molave was 17.8. The Hurricane Size Index (HSI) was 17.2 and the Hurricane Wind Intensity Size Index (HWISI) was 35.0. Molave was capable of causing regional serious damage.

Typhoon Molave will cause winds to typhoon force along the central coast of Vietnam. Molave will cause a significant storm surge near and to the north of where the center made landfall. Typhoon Molave will weaken steadily while it moves inland. Molave will drop locally heavy rain over parts of central Vietnam, southern Laos, northern Cambodia and northeastern Thailand. The surface in those areas is already saturated by rain dropped be previous tropical cyclones and other weather systems. Molave will almost certainly cause floods in some locations.

Elsewhere over the Western North Pacific, a new tropical depression formed east of the Philippines. At 11:00 p.m. EDT on Tuesday the center of Tropical Depression 22W was located at latitude 16.6°N and longitude 139.6°E which put it about 1200 miles (1965 km) east of the Philippines. The depression was moving toward the west at 7 m.p.h. (11 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 1006 mb. The tropical depression is forecast to move toward the Philippines and to strengthen into a typhoon.

Typhoon Molave Brings Wind and Rain to the Philippines

Typhoon Molave brought wind and rain to parts of the Philippines on Sunday. At 11:00 a.m. EDT on Sunday the center of Typhoon Molave was located at latitude 13.5°N and longitude 122.2°E which put it about 75 miles (120 km) east of Calapan, Philippines. Molave was moving toward the west at 22 m.p.h. (350 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 982 mb.

Former Tropical Storm Molave intensified rapidly to a typhoon as it approached Luzon. A circular eye developed at the center of Typhoon Molave. The eye was surrounded by a ring of strong thunderstorms and the strongest winds were occurring in that ring of storms. Winds to typhoon force extended out 30 miles (50 km) from the center of circulation. Winds to tropical storm force extended out 150 miles (240 km) from the center.

The center of Typhoon Molave moved across southeastern Luzon near Tabaco. It was located near Marinduque Island. Molave was dropping heavy rain over parts of southern Luzon, Mariduque Island and Mindoro. Heavy rain could cause flash floods in some locations.

Typhoon Molave will move south of a high pressure system over the Western North Pacific Ocean. The high will steer Molave toward the west. On its anticipated track Typhoon Molave will move across Mindoro and over the South China Sea. Molave could approach the coast of central Vietnam in about 60 hours.

Typhoon Molave will move through an environment favorable for intensification during the next 24 to 48 hours. Molave will move over water where the Sea Surface Temperature is near 29°C. It will move under the southern part of an upper level ridge. The ridge will produce easterly winds which will cause some vertical wind shear. The wind shear will slow the rate of intensification but there will not be enough vertical wind shear to keep Typhoon Molave from intensifying when it moves over the South China Sea.

Elsewhere over the Western North Pacific Ocean, Tropical Storm Saudel was approaching the coast of central Vietnam. At 11:00 a.m. EDT on Sunday the center of Tropical Storm Saudel was located at latitude 17.5°N and longitude 107.4°E which put it about 50 miles (80 km) east of Xuan Duc, Vietnam. Saudel was moving toward the west at 4 m.p.h. (6 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 999 mb.

Saudel Weakens to a Tropical Storm

Former Typhoon Saudel weakened back to a tropical storm over the South China Sea on Friday. At 11:00 p.m. EDT on Friday the center of Tropical Storm Saudel was located at latitude 17.7°N and longitude 113.1°E which put it about 170 miles (280 km) east-southeast of Hainan. Saudel was moving toward the west at 8 m.p.h. (13 km/h). The maximum sustained wind speed was 65 m.p.h. (105 km/h) and there were wind gusts to 80 m.p.h. (130 km/h). The minimum surface pressure was 984 mb.

Tropical Storm Saudel weakened over the South China Sea on Friday. An upper level ridge over eastern Asia produced easterly winds which blew toward the top of Saudel. Those winds cause moderate vertical wind shear and they were the primary cause of the weakening of the former typhoon. Breaks developed in the ring of strong thunderstorms surrounding the eye. The distribution of thunderstorms became more asymmetrical. The strongest thunderstorms were occurring in bands in the western half of Tropical Storm Saudel. Bands in the eastern half of the circulation consisted primarily of showers and lower clouds. Winds to tropical storm force extended out 200 miles (320 km) from the center.

Tropical Storm Saudel will move through an environment unfavorable for intensification during the next several days.  Saudel will move over water where the Sea Surface Temperature is near 29°C.  However, the upper level ridge over eastern Asia will continue to cause moderate vertical wind shear. The wind shear, will cause Tropical Storm Saudel to continue to weaken during the weekend.

Tropical Storm Saudel will move south of a ridge of high pressure over eastern Asia.  The ridge will steer Saudel toward the west during the next several days.  On its anticipated track Tropical Storm Saudel will pass south of Hainan Island in about 24 hours. Saudel could approach the coast of Vietnam in about 36 hours. Saudel could still be a tropical storm when it approaches makes landfall on the central coast of Vietnam between Hue and Vinh. Even if Saudel weakens to a tropical depression, it will still drop locally heavy rain over parts of Vietnam and southern Laos. The heavy rain will cause floods in some locations where the ground is already saturated.

Elsewhere over the Western North Pacific Ocean, Tropical Depression Twentyone-W developed east of Luzon. At 11:00 p.m. EDT on Friday the center of Tropical Depression Twentyone-W was located at latitude 12.7°N and longitude 130.7°E which put it about 315 miles (510 km) east of Luzon. The depression was moving toward the west-northwest at 14 m.p.h. (22 km/h). The maximum sustained wind speed was 35 m.p.h. (505 km/h) and there were wind gusts to 45 m.p.h. (75 km/h). The minimum surface pressure was 1006 mb. The depression is forecast to move toward the Philippines and to strengthen into a tropical storm.

Tropical Storm Saudel Brings Wind and Rain to Luzon

Tropical Storm Saudel brought wind and rain to Luzon on Tuesday. At 11:00 a.m. EDT on Tuesday the center of Tropical Storm Saudel was located at latitude 15.8°N and longitude 121.6°E which put it about 120 miles (195 km) northeast of Manila, Philippines. Saudel was moving toward the west at 11 m.p.h. (17 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 997 mb.

The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) determined based on weather radar that the center of Tropical Storm Saudel made landfall on the east coast of Luzon north of Baler on Tuesday. Saudel was getting stronger at the time of landfall. The radar indicated that there was a small, tight center of circulation. Bands of showers and thunderstorms wrapped closely around the center of Tropical Storm Saudel. Other outer rainbands were revolving around the center. Satellite imagery showed that storms near the center were generating upper level divergence which pumped mass away to the west and north of the tropical storm. Winds to tropical storm force extended out 150 miles (240 km) from the center of Saudel.

Tropical Storm Saudel will move across northern Luzon during the next 12 hours. Saudel will bring gusty winds an it will drop locally heavy rain over parts of northern Luzon. Heavy rain could could cause flash floods in some locations. Tropical Storm Saudel will weaken while the center crosses Luzon. The center of Saudel is likely to emerge over the South China Sea near Baguio in about 12 hours.

Tropical Storm Saudel will move through an environment that will be favorable for intensification when it moves over the South China Sea.  Saudel will move over water where the Sea Surface Temperature is near 30°C.  It will be under the southern part of an upper level ridge.  The ridge will produce easterly winds which will blow toward the top of the circulation.  Those winds will cause some vertical wind shear.  The shear will inhibit intensification but it will not be strong enough to keep Tropical Storm Saudel from intensifying. Saudel will begin to strengthen again when it moves back over water and it could intensify into a typhoon.

Tropical Storm Saudel will move south of a ridge of high pressure over eastern Asia.  The ridge will steer Saudel toward the west during the next several days.  On its anticipated track Tropical Storm Saudel will approach the coast of Vietnam in a few days.

Tropical Storm Saudel Develops East of Luzon

Tropical Storm Saudel developed east of Luzon on Monday night. At 11:00 p.m. EDT on Monday the center of Tropical Storm Saudel was located at latitude 15.8°N and longitude 124.3°E which put it about 185 miles (300 km) east of Baler, Philippines. Saudel was moving toward the west-northwest at 15 m.p.h. (24 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 1000 mb.

A low pressure system east of Luzon strengthened on Monday night and the Japan Meteorological Agency designated the system as Tropical Storm Saudel. The circulation around Tropical Storm Saudel exhibited more organization on satellite images. Bands of showers and thunderstorms were revolving around the center of Saudel. Storms near the center generated upper level divergence which pumped mass away from the tropical storm. Winds to tropical storm force extended out 100 miles (160 km) from the center of circulation.

Tropical Storm Saudel will move through an environment that will be somewhat favorable for intensification during the next 12 hours.  Saudel will move over water where the Sea Surface Temperature is near 30°C.  It will be under the southern part of an upper level ridge.  The ridge will produce easterly winds which will blow toward the top of the circulation.  Those winds will cause some vertical wind shear.  Tropical Storm Saudel will start to move across northern Luzon in about 12 hours. Saudel will weaken while it moves over Luzon. Tropical Storm Saudel will move over the South China Sea in about 24 hours. Saudel will begin to strengthen again when it moves back over water.

Tropical Storm Saudel will move south of a ridge of high pressure over eastern Asia.  The ridge will steer Saudel toward the west-northwest.  On its anticipated track Tropical Storm Saudel will reach the coast of northern Luzon in about 12 hours. Saudel will bring gusty winds and locally heavy rain to northern Luzon. Heavy rain could cause flash floods in some parts of Luzon. Tropical Storm Saudel could approach the coast of Vietnam in a few days.

Tropical Storm Linfa Makes Landfall in Vietnam

Tropical Storm Linfa made landfall on the coast of Vietnam on Sunday.  At 11:00 a.m. EDT on Sunday the center of Tropical Storm Linfa was located at latitude 15.4°N and longitude 107.4°E which put it about 50 miles (80 km) east of Lamam, Laos.  Linfa was moving toward the west 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 1000 mb.

The center of Tropical Storm Linfa made landfall on the central coast of Vietnam south of Da Nang on Sunday.  Linfa brought tropical storm force winds to the portion of the coast south of Da Nang.  Tropical Storm Linfa dropped heavy rain over central Vietnam, southern Laos and northeastern Cambodia.  Linfa is forecast to continue to move toward the west and it will be over northeastern Thailand on Monday.

Elsewhere over the Western North Pacific Ocean, Tropical Storm Chan-hom weakened southeast of Japan and a new tropical depression formed west of the Philippines.  At 11:00 a.m. EDT on Sunday the center of Tropical Storm Chan-hom was located at latitude 31.1°N and longitude 142.2°E which put it about 300 miles (485 km) south-southeast of Tokyo, Japan.  Chan-hom was moving toward the southeast at 8 m.p.h. (13 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 1000 mb.

(16 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 1002 mb.

Maysak Intensifies into a Typhoon East of Luzon

Former Tropical Storm Maysak intensified into a typhoon on Saturday.  At 5:00 p.m. EDT on Saturday the center of Typhoon Maysak was located at latitude 17.2°N and longitude 128.7°E which put it about 335 miles (540 km) east of Luzon.  Maysak was moving toward the west-northwest 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 976 mb.

The circulation around Typhoon Maysak exhibited greater organization on Saturday.  The inner end of a rainband wrapped partially around the center of circulation and an eye could be forming at the center of Maysak.  Bands of showers and thunderstorms were revolving around the core of Maysak.  Storms near the core were generating upper level divergence which was pumping mass away from the core.  Winds to typhoon force extended out 30 miles (50 km) from the center of circulation.  Winds to tropical storm force extended out 185 miles (295 km) from the center.

Typhoon Maysak will move through an environment favorable for intensification during the next 36 to 48 hours.  Maysak will move over water where the Sea Surface Temperature is near 30°C.  It will move through a region where the upper level winds will be weak and there will be little vertical wind shear.  Typhoon Maysak will continue to strengthen and it could intensify rapidly when an eye and eyewall are fully formed.  Maysak could strengthen into the equivalent of a major hurricane within 24 to 36 hours.

Typhoon Maysak will move around the western end of a subtropical high pressure system over the Western North Pacific Ocean.  The high will steer Maysak toward the north during the next several days.  On its anticipated track Typhoon Maysak will move toward the southern Ryukyu Islands.  Maysak could pass near Okinawa in about 48 hours.  Typhoon Maysak is likely to be the equivalent of a major hurricane when it passes near Okinawa.

Tropical Storm Maysak Forms East of Luzon

Tropical Storm Maysak formed east of Luzon on Friday.  At 11:00 a.m. EDT on Friday the center of Tropical Storm Maysak was located at latitude 16.4°N and longitude 129.4°E which put it about 435 miles (700 km) east of Luzon.  Maysak was moving toward the west-southwest 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 997 mb.

More thunderstorms developed near the center of a low pressure system east of Luzon on Friday and the Japan Meteorological Agency designated the system as Tropical Storm Maysak.  Thunderstorms were also forming in bands revolving around the center of Maysak.  Storm nears the center were generating upper level divergence which was pumping mass away from the tropical storm.  Winds to tropical storm force extended out 140 miles (225 km) from the center of circulation.

Tropical Storm Maysak will move through an environment favorable for intensification during the next 48 hours.  Maysak will move over water where the Sea Surface Temperature is near 30°C.  It will move through a region where the upper level winds are weak and there will be little vertical wind shear.  Tropical Storm Maysak will intensify quickly and it could strengthen into a typhoon within 24 hours.  Once an inner core with an eye and an eyewall is established Maysak could rapidly intensify into the equivalent of a major hurricane.

Tropical Storm Maysak will move around the western end of a subtropical high pressure system over the Western North Pacific Ocean.  The high will steer Maysak toward the north-northwest.  On its anticipated track Tropical Storm Maysak could approach the Ryukyu Islands within 72 hours.  Maysak could be the equivalent of a major hurricane by that time.

Tropical Depression Develops West of Luzon

A tropical depression developed west of Luzon on Thursday night.  At 11:00 p.m. EDT on Thursday the center of Tropical Depression 02W was located at latitude 16.3°N and longitude 119.2°E which put it about 135 miles (215 km) northwest of Manila, Philippines.  The depression was moving toward the west-northwest at 14 m.p.h. (22 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 1002 mb.

An area of low pressure moved west of Luzon on Thursday night and several weather agencies classified the system as a tropical depression.  The circulation around Tropical Depression 02W was not well organized.  There were a number of fragmented bands of showers and thunderstorms revolving around the center of the depression.  The strongest thunderstorms were in bands west and north of the center.  Bands east of the center of circulation were still over the Philippines and those bands consisted primarily of showers and lower clouds.

Tropical Depression 02W will move through an environment favorable for intensification during the next 24 to 36 hours.  The depression will move over water where the Sea Surface Temperature is near 30.5°C.  It will move under the southwestern portion of an upper level ridge centered northeast of Taiwan.  The ridge will produce easterly winds which will blow toward the top of the depression.  Those winds will cause some vertical wind shear and the shear will inhibit intensification.  Tropical Depression 02W is likely to intensify into a tropical storm during the next 24 hours in spite of the vertical wind shear.

Tropical Depression 02W will move around the southwestern end of a subtropical high pressure system over the Western North Pacific Ocean.  The high will steer the depression toward the northwest during the next 36 to 48 hours.  On its anticipated track Tropical Depression 02W will approach the coast of China west of Hong Kong in about 48 hours.  It will likely be a tropical storm at that time.

Tropical Storm Vongfong Brings Wind and Rain to Luzon

Tropical Storm Vongfong brought wind and rain to Luzon on Friday.  At 11:00 am. EDT on Friday the center of Tropical Storm Vongfong was located at latitude 15.6°N and longitude 121.2°E which put it about 45 miles (75 km) northeast of Manila, Philippines.  Vongfong was moving toward the north-northwest at 13 m.p.h. (20 km/h).  The maximum sustained wind speed was 65 m.p.h. (105 km/h) and there were wind gusts to 80 m.p.h. (130 km/h).  The minimum surface pressure was 990 mb.

Former Typhoon Vongfong weakened to a tropical storm on Friday after the center passed across northern Samar and southeastern Luzon.  The circulation around Tropical Storm Vongfong was small but it remained well organized.  The strongest winds were occurring in rainbands in the eastern half of the circulation which was over the Philippine Sea.  Winds to tropical storm force extended out 50 miles (80 km) from the center of circulation.  The wind speeds were not as strong over land, although stronger winds may have been occurring at locations in mountainous regions.

Tropical Storm Vongfong dropped locally heavy rain over southeastern and eastern Luzon.  The center of Vongfong passed west of Legaspi and east of Manila.  Heavy rain may have fallen on the slopes of the Mayon Volcano and flash floods could have occurred in that region.

Tropical Storm Vongfong will move around the western end of a high pressure system centered southeast of Japan.  The high steer Vongfong toward the north during the next 24 hours.  The tropical storm will start to move toward the northeast during the weekend after it moves around the western end of the high pressure system.  On its anticipated track Tropical Storm Vongfong will move over northern Luzon during the next 24 hours.  Vongfong will continue to bring gusty winds and drop locally heavy rain over parts of northern Luzon.
