Tropical Storm Ma-on Brings Wind and Rain to Northern Luzon

Tropical Storm Ma-on brought wind and rain to northern Luzon on Tuesday morning. At 5:00 a.m. EDT on Tuesday the center of Tropical Storm Ma-on was located at latitude 18.0°N and longitude 121.2°E which put it about 50 miles (80 km) southeast of Claveria, Philippines. Ma-on was moving toward the northwest at 12 m.p.h. (19 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 985 mb.

Tropical Storm Ma-on brought gusty winds and locally heavy rain to parts of northern Luzon on Tuesday morning. The center of Ma-on made landfall on the northeastern coast of Luzon east of Tuguegarao during Monday night. Tropical Storm Ma-on moved northwest across northern Luzon. Ma-on intensified before it made landfall and it was almost a typhoon at the time of landfall. Winds to tropical storm force extended out 120 miles (195 km) from the center of Ma-on’s circulation.

Tropical Storm Ma-on will move through an environment favorable for intensification when it moves over the South China Sea. Ma-on will move over water where the Sea Surface Temperatures are 29˚C. It will move under the southern part of an upper level ridge over China. The ridge will produce easterly winds that will blow toward the top of Ma-on’s circulation. Those winds will cause some vertical wind shear, but the wind shear will not be enough to prevent intensification. Tropical Storm Ma-on is likely to strengthen to a typhoon during the next 36 hours.

Tropical Storm Ma-on will move around the southwestern part of a high pressure system over the Western North Pacific Ocean. The high pressure system will steer Ma-on toward the west-northwest during the next 36 hours. On its anticipated track Tropical Storm Ma-on will move away from northern Luzon later on Tuesday. Ma-on will continue to bring gusty winds and locally heavy rain to northern Luzon until it moves farther away. Heavy rain could cause flash floods in some locations. Ma-on could be south of Hong Kong in 36 hours.

Elsewhere over the Western North Pacific Ocean, former Tropical Storm Tokage intensified to a typhoon southeast of Japan. At 5:00 a.m. EDT on Tuesday the center of Typhoon Tokage was located at latitude 30.8°N and longitude 149.6°E which put it about 670 miles (1080 km) southeast of Tokyo, Japan. Tokage was moving toward the north-northwest at 19 m.p.h. (30 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 979 mb.

Tropical Storm Ma-on Develops near Northern Luzon

Tropical Storm Ma-on developed near northern Luzon on Sunday night. At 5:00 a.m. EDT on Monday the center of Tropical Storm Ma-on was located at latitude 16.3°N and longitude 123.4°E which put it about 100 miles (160 km) southeast of Tuguegarao, Philippines. Ma-on 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.

Former Tropical Depression 10W strengthened to Tropical Storm Ma-on just to the east of northern Luzon on Sunday night. The distribution of thunderstorms in Ma-on continued to be asymmetrical. Most of the thunderstorms were in bands in the southern half of Ma-on’s circulation. The bands in the northern half of the circulation consisted primarily of showers and lower clouds. A strong upper level ridge over China was producing strong northerly winds that were blowing toward the top of Tropical Storm Ma-on. Those winds were causing moderate vertical wind shear and the wind shear was causing the asymmetrical distribution of thunderstorms.

Tropical Storm Ma-on will move through an environment favorable for intensification during the next 12 hours. Ma-on will move over water where the Sea Surface Temperatures are 30˚C. The upper level ridge over China will continue to produce northerly winds that will blow toward the top of Ma-on’s circulation. However, Tropical Storm Ma-on could strengthen during the next 12 hours. Ma-on will weaken when the center passes over northern Luzon, but it could strengthen again over the South China Sea later this week.

Tropical Storm Ma-on will move around the southwestern part of a high pressure system over the Western North Pacific Ocean. The high pressure system will steer Ma-on toward the west-northwest during the next 24 hours. On its anticipated track Tropical Storm Ma-on will hit northern Luzon in 12 hours. Ma-on will bring gusty winds and locally heavy rain to northern Luzon. Heavy rain could cause flash floods in some locations.

Elsewhere over the Western North Pacific Ocean, Tropical Storm Tokage formed southeast of Japan. At 5:00 a.m. EDT on Monday the center of Tropical Storm Tokage was located at latitude 25.5°N and longitude 151.6°E which put it about 1010 miles (1635 km) southeast of Tokyo, Japan. Tokage was moving toward the north 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 998 mb.

Tropical Depression Forms East of Luzon

A tropical depression formed over the Western North Pacific Ocean east of Luzon on Sunday morning. At 5:00 a.m. EDT on Sunday the center of the tropical depression was located at latitude 17.4°N and longitude 127.3°E which put it about 350 miles (565 km) east of Luzon. The tropical depression was moving toward the west at 5 m.p.h. (8 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 1000 mb.

A distinct low level center of circulation formed in an area of lower pressure east of Luzon on Sunday morning and the Japan Meteorological Agency classified the system as a tropical depression. The distribution of thunderstorms in the tropical depression was asymmetrical. Most of the thunderstorms were in bands in the western half of the tropical depression. The bands in the eastern half of the circulation consisted primarily of showers and lower clouds. A strong upper level ridge over China was producing strong northeasterly winds that were blowing toward the top of the tropical depression. Those winds were causing moderate vertical wind shear and the wind shear was causing the asymmetrical distribution of thunderstorms.

The tropical depression will move through an environment favorable for intensification during the next 24 hours. The tropical depression will move over water where the Sea Surface Temperatures are 30˚C. The upper level ridge over China will continue to produce northeasterly winds that will blow toward the top of the tropical depression. However, the upper level winds are forecast to weaken. The vertical wind shear could decrease during the next 24 hours. The tropical depression is forecast to strengthen to a tropical storm.

The tropical depression will move around the southwestern part of a high pressure system over the Western North Pacific Ocean. The high pressure system will steer the tropical depression toward the west during the next 24 hours. On its anticipated track the tropical depression could approach northeastern Luzon in 24 hours. It is likely to be a tropical storm when it approaches Luzon. The weather system will bring gusty winds and locally heavy rain to northern Luzon. Heavy rain could cause flash floods in some locations.

Tropical Storm Kompasu Brings Wind and Rain to Northern Luzon

Tropical Storm Kompasu brought wind and rain to northern Luzon on Monday. At 11:00 a.m. EDT on Monday the center of Tropical Storm Kompasu was located at latitude 18.9°N and longitude 120.9°E which put it about 35 miles (55 km) north of Claveria, Philippines. Kompasu was moving toward the west at 16 m.p.h. (26 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 981 mb.

Rainbands in the southern side of Tropical Storm Kompasu brought wind and rain to northern Luzon on Monday. The center of Kompasu passed just north of Luzon. Thunderstorms in bands in southern half of Tropical Storm Kompasu passed over the northern end of Luzon. Kompasu strengthened as it approached northern Luzon. More thunderstorms developed in bands revolving around the center of Tropical Storm Kompasu. Storms near the center of circulation generated upper level divergence that pumped mass away from the tropical storm. Winds to tropical storm force extended out 145 miles (235 km) from the center of Kompasu.

Tropical Storm Kompasu will move through an environment somewhat favorable for intensification during the next 36 hours. Kompasu will move over water where the Sea Surface Temperatures are near 29˚C. It will move south of an upper level ridge over China. The ridge will produce northeasterly winds that will blow toward the top of Kompasu’s circulation. Those winds will cause moderate vertical wind shear and the wind shear will inhibit intensification. Tropical Storm Kompasu is likely to strengthen gradually during the next 24 hours. Kompasu could intensify to a typhoon over the South China Sea.

Tropical Storm Kompasu will move south of a high pressure system over China. The high pressure system will steer Kompasu toward the west during the next several days. On its anticipated track the center of Tropical Storm Kompasu will pass south of Hong Kong in 24 hours. Kompasu could approach Hainan in 36 hours.

Elsewhere over the Western North Pacific Ocean, Tropical Storm Namtheun intensified east of the northern Marianas. At 11:00 a.m. EDT on Monday the center of Tropical Storm Namtheun was located at latitude 19.4°N and longitude 154.0°E which put it about 555 miles (895 km) east of Agrihan. Namtheun was moving toward the west-northwest at 16 m.p.h. (26 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 988 mb.

Lionrock 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 995 mb.

Tropical Storm Lionrock dropped heavy rain over the part of northern Vietnam between Hanoi and Haiphong on Saturday night. The heaviest rain was falling in bands in the western half of Tropical Storm Lionrock. Bands in the eastern side of Lionrock consisted primarily of showers and lower clouds. Winds to tropical storm force extended out 120 miles (195 km) from the center of Lionrock’s circulation.

Tropical Storm Lionrock will move south of a high pressure system over China during the next 24 hours. The high pressure system will steer Lionrock toward the west during the next day or so. On its anticipated track Tropical Storm Lionrock will move across northern Vietnam and northern Laos. Lionrock will bring gusty winds and locally heavy rain to parts of northern Vietnam and northern Laos. Heavy rain could cause flash floods in some locations.

Elsewhere over the Western North Pacific Ocean, Tropical Storm Kompasu was spinning east of Luzon and Tropical Storm Namtheun formed east of the northern Marianas. At 11:00 p.m. EDT on Saturday the center of Tropical Storm Kompasu was located at latitude 15.9°N and longitude 129.8°E which put it about 470 miles (760 km) east of Luzon.

Typhoon Chanthu Brings Wind and Rain to Northeast Luzon

Typhoon Chanthu brought wind and rain to northeastern Luzon on Friday. At 5:00 a.m. EDT on Friday the center of Typhoon Chanthu was located at latitude 18.3°N and longitude 123.1°E which put it about 100 miles (160 km) east of Aparri, Philippines. Chanthu was moving toward the northwest at 12 m.p.h. (19 km/h). The maximum sustained wind speed was 165 m.p.h. (265 km/h) and there were wind gusts to 200 m.p.h. (320 km/h). The minimum surface pressure was 915 mb.

Even though the center of Typhoon Chanthu was passing northeast of northeastern Luzon, bands on the western side of Chanthu brought gusty wind and heavy rain to northeastern Luzon. Typhoon Chanthu strengthened back to the equivalent of a Category 5 hurricane on the Saffir-Simpson Scale after it completed an eyewall replacement cycle on Thursday. A circular eye was present at the center of Chanthu. The eye was surrounded by a ring of strong thunderstorms and the strongest winds were occurring in that ring of storms. Storms near the core of Chanthu generated strong upper level divergence that pumped mass away from the typhoon in all directions.

The circulation around Typhoon Chanthu was relatively small. Winds to typhoon force extended out 45 miles (75 km) from the center of Chanthu. Winds to tropical storm force extended out 90 miles (145 km) from the center of circulation. The Hurricane Intensity Index (HII) for Typhoon Chanthu was 36.8. The Hurricane Size Index (HSI) was 14.1 and the Hurricane Wind Intensity Size Index (HWISI) was 50.9. Typhoon Chanthu was capable of causing regional catastrophic damage.

Typhoon Chanthu will move over water capable of supporting an intense typhoon during the next 24 hours. Chanthu 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. If the inner end of a rainband wraps around the existing eye and eyewall, another eyewall replacement cycle could start. If another eyewall replacement cycle occurs, Typhoon Chanthu would weaken, but the size of the circulation would increase.

Typhoon Chanthu will move around the western end of a high pressure system during the next few days. The high pressure system will steer Chanthu toward the northwest during the next 24 hours. On its anticipated track Typhoon Chanthu will gradually move away from northeastern Luzon. Chantu will approach southern Taiwan in 24 hours. Typhoon Chanthu will bring very strong winds and heavy rain to Taiwan. Widespread flash floods could occur.

Elsewhere over the Western North Pacific Ocean, Tropical Storm Conson moved toward central Vietnam. At 5:00 a.m. EDT on Friday the center of Tropical Storm Conson was located at latitude 15.6°N and longitude 111.7°E which put it about 250 miles (400 km) east of Da Nang, Vietnam. Conson was moving toward the west 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 997 mb.

Dangerous Typhoon Chanthu Nears Northeast Luzon

Dangerous Typhoon Chanthu neared northeastern Luzon on Thursday night. At 11:00 p.m. EDT on Thursday the center of Typhoon Chanthu was located at latitude 17.5°N and longitude 123.7°E which put it about 135 miles (215 km) southeast of Aparri, Philippines. Chanthu was moving toward the west-northwest at 12 m.p.h. (19 km/h). The maximum sustained wind speed was 150 m.p.h. (240 km/h) and there were wind gusts to 185 m.p.h. (295 km/h). The minimum surface pressure was 925 mb.

Typhoon Chanthu completed an eyewall replacement cycle on Thursday and Chanthu was strengthening again. The original eye and eyewall were almost entirely dissipated. A new, slightly larger eye was visible at the center of Typhoon Chanthu on satellite images. The eye was surrounded by a ring of strong thunderstorms and the strongest winds were occurring in that ring of storms. Bands of showers and thunderstorms were revolving around the core of Chanthu. Storms near the core generated strong upper level divergence that pumped large quantities of mass away from the typhoon.

Although the eyewall replacement cycle increased the size of the core of Typhoon Chanthu, the total circulation around Chanthu was relative small. Winds to typhoon force extended out 45 miles (75 km) from the center of Chanthu. Winds to tropical storm force extended out 90 miles (145 km) from the center of circulation. The Hurricane Intensity Index (HII) for Typhoon Chanthu was 31.6. The Hurricane Size Index (HSI) was 13.7 and the Hurricane Wind Intensity Size Index (HWISI) was 45.3. Typhoon Chanthu was capable of causing regional severe damage.

Typhoon Chanthu will move through an environment favorable for intensification during the next 12 hours. Chanthu 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. Typhoon Chanthu could strengthen during the next 12 hours. Chanthu will weaken if the core of the typhoon moves over northeastern Luzon. If the core of Typhoon Chanthu passes northeast of Luzon, then it could maintain its intensity during the next 36 hours.

Typhoon Chanthu will move around the western end of a high pressure system during the next few days. The high pressure system will steer Chanthu toward the northwest during the next 24 hours. On its anticipated track the core of Typhoon Chanthu will pass very close to northeastern Luzon. Chanthu could cause severe damage to northeastern Luzon. Typhoon Chantu will bring very strong winds and locally heavy rain. Heavy rain is likely to cause flash floods. Typhoon Chantu could affect Taiwan during the weekend.

Elsewhere over the Western North Pacific Ocean, Tropical Storm Conson moved toward central Vietnam. At 11:00 p.m. EDT on Thursday the center of Tropical Storm Conson was located at latitude 15.8°N and longitude 112.2°E which put it about 280 miles (460 km) east of Da Nang, Vietnam. Conson was moving toward the west-southwest at 13 m.p.h. (20 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.

Typhoon Chanthu Strengthens to Equivalent of Cat. 5 Hurricane

Typhoon Chanthu intensified to the equivalent of a Category 5 hurricane on the Saffir-Simpson Scale east of northern Luzon on Wednesday. At 5:00 a.m. EDT on Wednesday the center of Typhoon Chanthu was located at latitude 15.5°N and longitude 130.8°E which put it about 630 miles (1015 km) east-southeast of Aparri, Philippines. Chanthu was moving toward the west-southwest at 12 m.p.h. (19 km/h). The maximum sustained wind speed was 160 m.p.h. (260 km/h) and there were wind gusts to 195 m.p.h. (315 km/h). The minimum surface pressure was 915 mb.

Typhoon Chanthu intensified to the equivalent of a Category 5 hurricane on Wednesday morning. A small eye was at the center of Typhoon Chanthu. The eye was surrounded by a ring of strong thunderstorms and the strongest winds were occurring in that ring of storms. Bands of showers and thunderstorms revolved around the core of Chanthu. Storms near the core generated strong upper level divergence that pumped mass away from the typhoon. The inner end of a rainband wrapped part of the way around the core of Typhoon Chanthu. Concentric eyewalls might be developing, which would indicate the start of an eyewall replacement cycle.

The circulation around Typhoon Chanthu was small. Winds to typhoon force extended out 20 miles (30 km) from the center of Chanthu. Winds to tropical storm force extended out 80 miles (130 km) from the center of circulation. The Hurricane Intensity Index (HII) for Typhoon Chanthu was 35.0. The Hurricane Size Index (HSI) was 7.1 and the Hurricane Wind Intensity Size Index (HWISI) was 42.1. Typhoon Chanthu was capable of causing localized catastrophic damage.

Typhoon Chanthu will move through an environment capable of maintaining a strong typhoon during the next 48 hours. Chanthu 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. If an eyewall replacement cycle occurs, Typhoon Chanthu will weaken when the inner eyewall weakens. An eyewall replacement cycle would increase the size of the circulation around Chanthu when the outer eyewall forms.

Typhoon Chanthu will move south of a high pressure system over the Western North Pacific Ocean. The high will steer Chanthu toward the west during the next several days. On its anticipated track Typhoon Chanthu could approach northeastern Luzon in 48 hours. Chanthu will likely still be a powerful typhoon when it approaches Luzon.

Elsewhere over the Western North Pacific Ocean, Tropical Storm Conson continued to bring wind and rain to parts of Luzon. At 5:00 a.m. EDT on Wednesday the center of Tropical Storm Conson was located at latitude 14.3°N and longitude 120.5°E which put it about 35 miles (55 km) south-southwest of Manila, Philippines. Conson was moving toward the northwest 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 988 mb.

Typhoon Chanthu Rapidly Intensifies to Equivalent of Major Hurricane

Typhoon Chanthu rapidly intensified to the equivalent of a major hurricane over the Western North Pacific Ocean on Tuesday. At 5:00 p.m. EDT on Tuesday the center of Typhoon Chanthu was located at latitude 16.3°N and longitude 133.0°E which put it about 915 miles (1475 km) east-southeast of Taiwan. Chanthu was moving toward the west at 13 m.p.h. (20 km/h). The maximum sustained wind speed was 145 m.p.h. (230 km/h) and there were wind gusts to 175 m.p.h. (280 km/h). The minimum surface pressure was 929 mb.

Former Tropical Storm Chanthu rapidly intensified from a minimal tropical storm to the equivalent of a major hurricane during the past 24 hours. A small eye quickly developed at the center of Typhoon Chanthu. The eye was surrounded by a ring of strong thunderstorms and the strongest winds were occurring in that ring of storms. Bands of showers and thunderstorms were revolving around the core of Chanthu. Storms near the core generated strong upper level divergence that pumped mass away from the typhoon.

The circulation around Typhoon Chanthu was small. Winds to typhoon force extended out 20 miles (30 km) from the center of Chanthu. Winds to tropical storm force extended out 85 miles (135 km) from the center of circulation. The Hurricane Intensity Index (HII) for Typhoon Chanthu was 30.0. The Hurricane Size Index (HSI) was 7.4 and the Hurricane Wind Intensity Size Index (HWISI) was 37.4. Typhoon Chanthu was capable of causing localized severe damage.

Typhoon Chanthu will move through an environment favorable for intensification during the next 24 hours. Chanthu 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. Typhoon Chanthu could continue to intensify during the next 24 hours and there is a chance it could strengthen to the equivalent of a Category 5 hurricane on the Saffir-Simpson Scale.

Typhoon Chanthu will move south of a high pressure system over the Western North Pacific Ocean. The high will steer Chanthu toward the west during the next several days. On its anticipated track Typhoon Chanthu could approach northeastern Luzon in 60 hours. Chanthu could be near Taiwan in less than four days.

Elsewhere over the Western North Pacific Ocean, Tropical Storm Conson brought wind and rain to Luzon. At 5:00 p.m. EDT on Tuesday the center of Tropical Storm Conson was located at latitude 13.5°N and longitude 121.7°E which put it about 110 miles (175 km) southeast of Manila, Philippines. Conson was moving toward the west-northwest at 9 m.p.h. (15 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 988 mb.

Tropical Storm Conson Brings Wind and Rain to Central Philippines

Tropical Storm Conson brought wind and rain to the central Philippines on Monday. At 5:00 p.m. EDT on Monday the center of Tropical Storm Conson was located at latitude 11.7°N and longitude 124.6°E which put it about 50 miles (80 km) south-southeast of Calbayog, Philippines. Conson was moving toward the west-northwest at 12 m.p.h. (19 km/h). The maximum sustained wind speed was 70 m.p.h. (110 km/h) and there were wind gusts to 85 m.p.h. (135 km/h). The minimum surface pressure was 985 mb.

The center of Tropical Storm Conson made landfall on the east coast of Samar near Borongan on Monday. Conson was nearly a typhoon at the time of landfall. A small eye was visible at the center of Tropical Storm Conson on both radar and microwave satellite images. Conson produced gusty winds as it passed over Samar. Winds to tropical storm force extended out 45 miles (75 km) from the center of circulation. Tropical Storm Conson dropped heavy rain on Samar, Leyte, northern Cebu and northeastern Panay. Heavy rain could result in flash floods in some locations.

Tropical Storm Conson will move around the southern side of a high pressure system over the Western North Pacific Ocean. The high will steer Conson toward the northwest during the next 36 hours. On its anticipated track Tropical Storm Conson will pass over the Visayan Sea and the Sibuyan Sea. The center of Conson could pass over Masbate during the next 12 hours. Tropical Storm Conson could reach southern Luzon in a day or so. Conson could be be near Manila in 48 hours. Tropical Storm Conson will bring gusty winds and locally heavy rain to parts of Masbate, Mindoro and southern Luzon.

Tropical Storm Conson will move through an environment mostly favorable for intensification during the next 24 hours. Conson 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. Since the circulation around Tropical Storm Conson is small, it is likely to weaken each time the center passes over land. The intensity of Conson could fluctuate when it moves over islands and water surfaces.

Elsewhere over the Western North Pacific Ocean, Tropical Depression 19W was organizing quickly and it appeared to be on the verge of strengthening to a tropical storm. At 5:00 p.m. EDT on Monday the center of Tropical Depression 19W was located at latitude 15.5°N and longitude 137.1°E which put it about 1170 miles (1890 km) east-southeast of Taiwan.
