Typhoon Surigae Stalls East of Luzon

Typhoon Surigae stalled east of Luzon on Monday. At 11:00 p.m. EDT on Monday the center of Typhoon Surigae was located at latitude 15.6°N and longitude 126.1°E which put it about 310 miles (500 km) east of Baler, Philippines. Surigae was moving toward the north-northwest at 4 m.p.h. (6 km/h). The maximum sustained wind speed was 130 m.p.h. (210 km/h) and there were wind gusts to 160 m.p.h. (260 km/h). The minimum surface pressure was 944 mb.

Typhoon Surigae completed an eyewall replacement cycle on Monday. The inner eyewall weakened to a swirl of low clouds. There was a large circular eye at the center of Surigae. The eye had a diameter of 60 miles (95 km). The large 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 Surigae. Storms near the core generated upper level divergence that pumped mass away from the typhoon.

The eyewall replacement cycle left Typhoon Surigae with a symmetrical circulation. Winds to typhoon force extended out 65 miles (105 km) from the center of Surigae. Winds to tropical storm force extended out 180 miles (290 km) from the center. The Hurricane Intensity Index (HII) for Typhoon Surigae was 25.1. The Hurricane Size Index (HSI) was 23.9 and the Hurricane Wind Intensity Size Index (HWISI) was 49.0.

Typhoon Surigae will move through an environment capable of supporting a strong typhoon during the next 24 hours. Surigae will be over water where the Sea Surface Temperatures will be near 29°C. It will move under the western part of an upper level ridge over the Western North Pacific Ocean. The upper level winds are weak near the end of the ridge and there will be little vertical wind shear. Typhoon Surigae will be moving slowly and it could mix cooler water to the surface. The cooler water could cause Surigae to weaken gradually.

Typhoon Surigae will move around the western end of a subtropical high pressure system over the Western North Pacific Ocean during the next 36 hours. The high will steer Surigae toward the north-northwest during the next 36 hours. After that time Typhoon Surigae will approach the westerly winds in the middle latitudes. Those winds will turn Surigae toward the east. On its anticipated track, the core Typhoon Surigae with the strongest winds will remain east of Luzon.

Typhoon Surigae Spins East of the Philippines

Typhoon Surigae spun east of the Philippines on Sunday. At 5:00 p.m. EDT on Sunday the center of Typhoon Surigae was located at latitude 14.2°N and longitude 126.4°E which put it about 260 miles (420 km) east of Daet, Philippines. Surigae was moving toward the northwest at 6 m.p.h. (10 km/h). The maximum sustained wind speed was 140 m.p.h. (225 km/h) and there were wind gusts to 165 m.p.h. (275 km/h). The minimum surface pressure was 934 mb.

An eyewall replacement cycle was underway in the core of Typhoon Surigae and the typhoon was weakening. The inner part of a rainband wrapped around the original eye and eyewall and a much larger outer eyewall formed. The low level winds converged into the outer eyewall and the inner eyewall weakened. The fastest wind speeds were in the inner eyewall. So, the maximum wind speed decreased when the inner eyewall weakened. There were still remnants of the original inner eyewall inside the outer eyewall, but the strongest wind speeds were occurring in the outer eyewall.

Typhoon Surigae was still large and powerful. Winds to typhoon force extended out 60 miles (95 km) from the center of Surigae. Winds to tropical storm force extended out 195 miles (315 km) from the center of circulation. The Hurricane Intensity Index (HII) for Typhoon Surigae was 28.3. The Hurricane Size Index (HSI) was 16.9 and the Hurricane Wind Intensity Size Index (HWISI) was 45.2.

Typhoon Surigae will move through an environment capable of supporting a powerful typhoon during the next 24 hours. Surigae will be over water where the Sea Surface Temperatures will be near 29°C. It will move under the western part of an upper level ridge over the Western North Pacific Ocean. The ridge will produce southerly winds which will blow toward the top of the circulation. However, the winds at lower levels in the atmosphere will also blow from the south and there will be little vertical wind shear. Typhoon Surigae will likely weaken gradually as the eyewall replacement cycle is completed.

Typhoon Surigae will move around the western end of a subtropical high pressure system over the Western North Pacific Ocean during the next 48 hours. The high will steer Surigae toward the north-northwest during the next 48 hours. After that time Typhoon Surigae will approach the westerly winds in the middle latitudes. Those winds will turn Surigae toward the northeast. On its anticipated track, the core Typhoon Surigae with the strongest winds will remain east of Luzon.

Typhoon Vamco Makes Landfall Northeast of Manila

Typhoon Vamco made landfall on Luzon northeast of Manila on Wednesday. At 4:00 p.m. EST on Wednesday the center of Typhoon Vamco was located at latitude 15.0°N and longitude 120.6°E which put it about 35 miles (55 km) northeast of Manila, Philippines. Vamco was moving toward the west at 17 m.p.h. (28 km/h). The maximum sustained wind speed was 110 m.p.h. (175 km/h) and there were wind gusts to 130 m.p.h. (210 km/h). The minimum surface pressure was 956 mb.

Typhoon Vamco was strengthening when it made landfall on Luzon. Vamco was nearly the equivalent of a major hurricane at the time of landfall. The circulation around Typhoon Vamco also increased in size prior to landfall. Winds to typhoon force extended out 100 miles (160 km) on the northern side of Vamco. Winds to force extended out 40 miles (65 km) on the southern side of the typhoon. Winds to tropical storm force extended out 350 miles in the northern half of the circulation. Winds to tropical storm force extended out 150 miles in the southern half of Vamco. The Hurricane Intensity Index (HII) for Typhoon Vamco was 19.2. The Hurricane Size Index (HSI) was 28.4 and the Hurricane Wind intensity Size Index (HWISI) was 47.6. Typhoon Vamco was capable of causing widespread serious damage to Luzon.

The center of Typhoon Vamco passed over the Polillo Islands before it reached Luzon. The center of Vamco will pass just north Manila, but it will be close enough to cause strong winds. The center will pass near San Fernando and Olongapo before it moves over the South China Sea. Typhoon Vamco will drop very heavy rain over Luzon and significant floods could occur. There will also be widespread power outages.

Typhoon Vamco will weaken as it passes over Luzon, but Vamco could still be a typhoon when it reaches the South China Sea. A high pressure system over eastern Asia will steer Typhoon Vamco toward the west. On its anticipated track Vamco could approach Vietnam in two or three days.

Vamco Rapidly Intensifies to Typhoon East of Luzon

Former Tropical Storm Vamco rapidly intensified into a typhoon east of Luzon on Tuesday. At 10:00 p.m. EST on Tuesday the center of Typhoon Vamco was located at latitude 14.9°N and longitude 124.0°E which put it about 230 miles (375 km) east of Manila, Philippines. Vamco was moving toward the west at 16 m.p.h. (26 km/h). The maximum sustained wind speed was 85 m.p.h. (135 km/h) and there were wind gusts to 105 m.p.h. (165 km/h). The minimum surface pressure was 973 mb.

Typhoon Vamco intensified rapidly on Tuesday. A circular eye was visible 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 Typhoon Vamco. Storms near the center were generating upper level divergence which was pumping mass away from the typhoon. Winds to typhoon force extended out 30 miles (50 km) from the center of Vamco. Winds to tropical storm force extended out 175 miles (280 km) from the center of circulation.

Typhoon Vamco will move through an environment that will be favorable for intensification during the next 12 hours. Vamco will move over water where the Sea Surface Temperature is near 28°C. It will move through a region where the upper level winds are weak and there will be little vertical wind shear. Typhoon Vamco will continue to intensify rapidly and it could strengthen to the equivalent of a major hurricane.

Typhoon Vamco will move south of a high pressure system over the Western North Pacific Ocean. The high will steer Vamco toward the west during the next several days. On its anticipated track Typhoon Vamco will make landfall on the east coast of Luzon in about 12 hours. The center of Vamco will pass north of Manila and the core of Typhoon Vamco could come close to San Francisco.

Typhoon Vamco will bring strong winds and heavy rain to Luzon. Vamco will be capable of causing major damage. The heavy rain will cause flash floods in part of Luzon. Typhoon Vamco could cause a storm surge of up to 10 feet (3 meters) on the east coast of Luzon. Vamco will weaken when the center passes over Luzon, but it is likely to still be a typhoon when it passes north of Manila. Typhoon Vamco is also likely to cause widespread power outages on Luzon.

Elsewhere over the Western North Pacific Ocean, Tropical Depression Etau was dropping heavy rain over Cambodia. At 10:00 p.m. EST on Tuesday the center of Tropical Depression Etau was located at latitude 12.5°N and longitude 105.5°E which put it about 100 miles (160 km) northeast of Phnom Penh, Cambodia. Etau was moving toward the west at 12 m.p.h. (19 km/h). The maximum sustained wind speed was 25 m.p.h. (40 km/h) and there were wind gusts to 30 m.p.h. (50 km/h). The minimum surface pressure was 1006 mb.

Tropical Storm Etau Nears Vietnam, Vamco Threatens Philippines

Tropical Storm Etau neared Vietnam on Monday and newly formed Tropical Storm Vamco threatened the Philippines. At 4:00 a.m. EST on Monday the center of Tropical Storm Etau was located at latitude 12.8°N and longitude 111.6°E which put it about 170 miles (280 km) east of Tuy Hoa, Vietnam. Etau was moving toward the west at 15 m.p.h. (24 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 995 mb.

The distribution of thunderstorms around Tropical Storm Etau was asymmetrical. Etau was moving under the southern part of an upper level ridge over eastern Asia. The ridge was producing easterly winds which were blowing toward the top of Etau. Those winds were causing moderate vertical wind shear. The shear was causing the stronger thunderstorms to occur in bands on the western side of Tropical Storm Etau. The bands in the eastern side of Etau consisted primarily of showers and lower clouds. Winds to tropical storm force extended out 150 miles (240 km) in the northern half of Tropical Storm Etau. Winds to tropical storm force only extended out 50 miles in the southern half of Etau.

Tropical Storm Etau will move south of a high pressure system over eastern Asia. The high will steer Etau toward the west during the next two days. On its anticipated track the center of Etau will make landfall in Vietnam near Tuy Hoa in about 12 hours.

Tropical Storm Etau will move through an environment that should allow it to maintain its intensity until it makes landfall in Vietnam. Etau will move over water where the Sea Surface Temperature is near 28°C. The upper level ridge over eastern Asia will continue to cause moderate vertical wind shear which will limit intensification.

Since the stronger thunderstorms are in the western half of Tropical Storm Etau, heavy rain will fall over central Vietnam before the center of Etau makes landfall. Etau will drop locally heavy rain over central Vietnam, northern Cambodia, southern Laos and northeastern Thailand. The ground is already saturated in that region and flash floods are likely.

Elsewhere over the Western North Pacific Ocean, Tropical Storm Vamco developed east of the Philippines. At 4:00 a.m. EST on Monday the center of Tropical Storm Vamco was located at latitude 12.8°N and longitude 130.6°E which put it about 370 miles (605 km) east of Laoang, Philippines. Vamco was moving toward the northwest at 13 m.p.h. (20 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 1002 mb. Tropical Storm Vamco is forecast to move toward Luzon and to strengthen into a typhoon.

Dangerous Typhoon Goni Hits Catanduanes

Extremely dangerous Typhoon Goni hit Catanduanes Island on Saturday. At 5:00 p.m. EDT on Saturday the center of Typhoon Goni was located at latitude 13.7°N and longitude 124.4°E which put it about 25 miles (40 km) northeast of Virac, Philippines. Goni was moving toward the west-southwest at 16 m.p.h. (26 km/h). The maximum sustained wind speed was 195 m.p.h. (315 km/h) and there were wind gusts to 235 m.p.h. (380 km/h). The minimum surface pressure was 884 mb.

The eye of Typhoon Goni moved over the southern part of Catanduanes Island on Saturday. Despite the development of concentric eyewalls and the occurrence of an eyewall replacement cycle, Goni actually strengthened on Saturday. The original inner eyewall weakened and the outer eyewall contracted around the center of Typhoon Goni. Goni exhibited an eye with a diameter of 14 miles (22 km) when it made landfall on Catanduanes Island.

The circulation around Typhoon Goni increased in size during the eyewall replacement cycle. Winds to typhoon force extended out 60 miles (95 km) from the center of Goni. Winds to tropical storm force extended out 130 miles (210 km) from the center of circulation. The Hurricane Intensity Index (HII) for Typhoon Goni was 48.0. The Hurricane Size Index (HSI) was 16.0 and the Hurricane Wind Intensity Size Index (HWISI) was 64.0. Typhoon Goni was capable of causing catastrophic damage on a regional scale.

Typhoon Goni will also generate a storm surge of up to 20 feet (6 meters) along the coasts of Catanduanes Island and southeastern Luzon. Typhoon Goni will move west across the Philippines. Goni will weaken as the core passes over land. The center of Goni will make landfall in southeastern Luzon near Tabaco. The southern eyewall of Goni will produce strong winds in Legaspi. The northern eyewall will bring strong winds to Naga. Typhoon Goni could be near Manila in 18 hours and it could still be the equivalent of a major hurricane at that time. Goni will also drop locally heavy rain over southern Luzon and flash floods are likely.

Elsewhere over the Western North Pacific Ocean, Tropical Storm Atsani was organizing slowly east of the Philippines. At 5:00 p.m. EDT on Saturday the center of Tropical Storm Atsani was located at latitude 15.2°N and longitude 135.8°E which put it about 900 miles (1450 km) east of Luzon. Atsani was moving toward the west-northwest at 11 m.p.h. (17 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 1001 mb. Tropical Storm Atsani was forecast to move toward the west and to strengthen.

Potentially Catastrophic Typhoon Goni Nears Luzon

Potentially catastrophic Typhoon Goni neared Luzon on Saturday morning. At 5:00 a.m. EDT on Saturday the center of Typhoon Goni was located at latitude 14.6°N and longitude 126.9°E which put it about 300 miles (485 km) east-northeast of Labo, Philippines. Goni was moving toward the west-southwest at 15 m.p.h. (24 km/h). The maximum sustained wind speed was 180 m.p.h. (290 km/h) and there were wind gusts to 220 m.p.h. (355 km/h). The minimum surface pressure was 898 mb.

Typhoon Goni exhibited a double eyewall structure sometimes seen in very intense tropical cyclones. There was a small inner eye with a diameter of 6 miles (10 km). That eye was surrounded by a ring of strong thunderstorms and the strongest winds were occurring in that inner eyewall. A second, outer eyewall with a diameter of 35 miles (56 km) surrounded the inner core of Typhoon Goni. Storms near the core of Gone generated strong upper level divergence which pumped large quantities of mass away from the typhoon. The removal of so much mass allowed the surface pressure to remain very low. Bands of showers and thunderstorms were revolving around the core of the typhoon.

The circulation around Typhoon Goni increased in size when the double eyewalls formed. Winds to typhoon force extended out 35 miles (55 km) from the center of Goni. Winds to tropical storm force extended out 130 miles (210 km) from the center of circulation. The Hurricane Intensity Index (HII) for Typhoon Goni was 42.2. The Hurricane Size Index (HSI) was 13.6 and the Hurricane Wind Intensity Size Index (HWISI) was 55.8. Typhoon Goni was capable of causing catastrophic damage.

Typhoon Goni will move through an environment favorable for a strong typhoon during the next 12 hours. Goni 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. An eyewall replacement cycle could cause Typhoon Goni to start to weaken. If the original inner eyewall dissipates and convergence becomes concentrated into the new outer eyewall, then the wind speed will decrease. However, Goni is likely to maintain much of its intensity until it reaches Luzon.

Typhoon Goni will move south of a subtropical high pressure system over the Western North Pacific Ocean. The high will steer Goni toward the west. On its anticipated track Typhoon Goni will be near Cataduanes Island in 12 48 hours. Goni could be near Manila in 24 hours. Typhoon Goni is capable of causing catastrophic damage to Luzon. Goni could generate a storm surge of up to 20 feet (6 meters) along the coast of southeastern Luzon. Typhoon Goni will drop heavy rain over parts of Luzon and flash floods are likely.

Elsewhere over the Western North Pacific Ocean, Tropical Storm Atsani moved north of Yap. At 5:00 a.m. EDT on Saturday the center of Tropical Storm Atsani was located at latitude 14.6°N and longitude 138.2°E which put it about 1060 miles (1705 km) east of Luzon. Astani was moving toward the west 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 1001 mb. Tropical Storm Atsani was forecast to move toward the northwest and to strengthen.

Typhoon Goni Rapidly Intensifies Into Equivalent of Cat. 5 Hurricane

Typhoon Goni intensified rapidly into the equivalent of a Category 5 hurricane on the Saffir-Simpson Scale east of the Philippines on Thursday night. At 5:00 a.m. EDT on Friday the center of Typhoon Goni was located at latitude 16.2°N and longitude 131.2°E which put it about 620 miles (1000 km) east of Luzon. Goni was moving toward the west at 13 m.p.h. (20 km/h). The maximum sustained wind speed was 175 m.p.h. (280 km/h) and there were wind gusts to 205 m.p.h. (330 km/h). The minimum surface pressure was 912 mb. Typhoon Goni is capable of causing catastrophic damage.

Typhoon Goni continued to intensify rapidly on Thursday night. A small circular eye with a diameter of 10 miles (16 km) was at the center of Goni. 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 tight core of Typhoon Goni. Storms near the core generated strong upper level divergence which pumped mass away from the typhoon. The removal of mass allowed the surface pressure to decrease quickly which contributed to the rapid increase in wind speed.

Typhoon Goni will move through an environment favorable for a strong typhoon during the next 36 to 48 hours. Goni 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, then an eyewall replacement cycle could occur. The cycle would cause Goni to weaken when the original inner eyewall dissipates and convergence becomes concentrated into a new outer eyewall. An eyewall replacement cycle would also cause the size of the circulation around Goni to Increase.

Typhoon Goni will move south of a subtropical high pressure system over the Western North Pacific Ocean. The high will steer Goni toward the west. On its anticipated track Typhoon Goni will approach the coast of Luzon in about 48 hours. Goni is likely to be the equivalent of a major hurricane when it approaches Luzon.

Elsewhere over the Western North Pacific Ocean, Tropical Storm Atsani moved south of the Marianas. At 5:00 a.m. EDT on Friday the center of Tropical Storm Atsani was located at latitude 11.6°N and longitude 142.6°E which put it about 170 miles (275 km) south-southwest of Guam. Astani was moving toward the west-northwest at 30 m.p.h. (48 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 1001 mb. Tropical Storm Atsani was forecast to move toward the northwest and to strengthen.

Typhoon Goni Rapidly Intensifies to Equivalent of a Major Hurricane

Typhoon Goni intensified rapidly into the equivalent of a major hurricane east of the Philippines on Thursday. At 11:00 p.m. EDT on Thursday the center of Typhoon Goni was located at latitude 16.2°N and longitude 132.2°E which put it about 690 miles (1115 km) east of Luzon. Goni was moving toward the west at 7 m.p.h. (11 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 934 mb.

Typhoon Goni intensified rapidly on Thursday. A small circular eye with a diameter of 12 miles (19 km) was at the center of Goni. 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 Typhoon Goni. Storms near the core generated strong upper level divergence which pumped mass away from the typhoon. The removal of mass allowed the surface pressure to decrease quickly which contributed to the rapid increase in wind speed.

The circulation around Typhoon Goni was small. Winds to typhoon force extended out 25 miles (40 km) from the center of Goni. Winds to tropical storm force extended out 100 miles (160 km) from the center of circulation. The Hurricane Intensity Index (HII) for Typhoon Goni was 29.9. The Hurricane Size Index (HSI) was 6.3 and the Hurricane Wind Intensity Size Index (HWISI) was 36.2.

Typhoon Goni will move through an environment favorable for intensification during the next 24 hours. Goni 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. Goni could intensify more during the next 24 hours. If the inner end of a rainband wraps around the existing eye and eyewall, then an eyewall replacement cycle could cause Goni to weaken.

Typhoon Goni will move south of a subtropical high pressure system over the Western North Pacific Ocean. The high will steer Goni toward the west. On its anticipated track Typhoon Goni will approach the coast of Luzon in about 48 hours. Goni is likely to be the equivalent of a major hurricane when it approaches Luzon.

Elsewhere over the Western North Pacific Ocean, Tropical Storm Atsani moved south-southeast of the Marianas. At 11:00 p.m. EDT on Thursday the center of Tropical Storm Atsani was located at latitude 10.7°N and longitude 145.3°E which put it about 245 miles (400 km) south-southeast of Guam. Astani was moving toward the northwest at 18 m.p.h. (30 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 1001 mb. Tropical Storm Atsani was forecast to move toward the northwest and to strengthen.

At 11:00 a.m. EDT on Thursday the center of Typhoon Goni was located at latitude 16.7°N and longitude 134.1°E which put it about 820 miles (1320 km) east of Luzon. Goni was moving toward the west at 14 m.p.h. (22 km/h). The maximum sustained wind speed was 90 m.p.h. (145 km/h) and there were wind gusts to 115 m.p.h. (185 km/h). The minimum surface pressure was 973 mb.

Typhoon Goni intensified rapidly on Thursday. A small circular eye was at the center of Goni. 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 Typhoon Goni. Storms near the core generated strong upper level divergence which pumped mass away from the typhoon. The removal of mass allowed the surface pressure to decrease quickly which contributed to the rapid increase in wind speed. The circulation around Typhoon Goni was small. Winds to typhoon force extended out 20 miles (30 km) from the center of Goni. Winds to tropical storm force extended out 80 miles (130 km) from the center of circulation.

Typhoon Goni will move through an environment favorable for intensification during the next several days. Goni 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. Goni could intensify into the equivalent of a major hurricane during the next 24 hours.

Typhoon Goni will move south of a subtropical high pressure system over the Western North Pacific Ocean. The high will steer Goni toward the west. On its anticipated track Typhoon Goni will approach the coast of Luzon in about 72 hours. Goni is likely to be the equivalent of a major hurricane when it approaches Luzon.
