Typhoon Phanfone Moves Away from the Philippines

Typhoon Phanfone moved away from the Philippines on Wednesday after bringing wind and rain to the central Philippines.  At 10:00 p.m. EST on Wednesday the center of Typhoon Phanfone was located at latitude 13.2°N and longitude 118.3°E which put it about 190 miles (310 km) west-southwest of Manila, Philippines.  Phanfone was moving toward the west-northwest at 9 m.p.h. (15 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 975 mb.

Typhoon Phanfone weakened earlier on Wednesday.  The core of Phanfone moved over southern Mindoro and the typhoon weakened when the circulation was disrupted by the mountains.  Satellite imagery suggested that the circulation around Typhoon Phanfone might be reorganizing on Wednesday night.  A small circular eye reappeared on visible satellite images.  Thunderstorms in the eyewall were growing taller.  Storms around the core of Phanfone were generating upper level divergence which was pumping mass away from the typhoon.  Winds to typhoon force extended out 40 miles (65 km) north of the center of circulation and out 20 miles (30 km) south of the center.  Winds to tropical storm force extended out 100 miles (160 km) from the center of Phanfone.

Typhoon Phanfone will move through an environment capable of supporting a typhoon for another 24 hours.  Phanfone will move over water where the Sea Surface Temperature is near 29°C.  It will move through a region where the upper level winds are weak and there will be little vertical wind shear.  In about 24 hours Typhoon Phanfone will reach an area where winds near the surface are blowing from the northeast.  Those winds will bring drier air which will get pulled into the circulation around Phanfone.  Typhoon Phanfone will weaken when the drier air enters its circulation.

Typhoon Phanfone will move south of a subtropical high pressure system over the Western North Pacific Ocean.  The high will steer Phanfone toward the west-northwest.  On its anticipated track Typhoon Phanfone will move across the South China Sea and it will move farther away from the Philippines.

Typhoon Phanfone Hits Panay Island

Typhoon Phanfone hit Panay Island on Tuesday.  At 10:00 p.m. EST on Tuesday the center of Typhoon Phanfone was located at latitude 11.9°N and longitude 121.8°E which put it about 50 miles (80 km) southeast of San Jose, Philippines.  Phanfone was moving toward the west at 12 m.p.h. (19 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 963 mb.

The eye of Typhoon Phanfone passed over the northern coast of Panay Island on Tuesday.  The southern part of the eyewall affected Roxas City, Kalibo and Ibajay.  Strong winds and heavy rain moved over the northern coast of Panay.  The northern eyewall was over Tablas Island and the northwestern part of the eyewall reached southeastern Mindoro.  Gusty winds may reach Roxas and San Jose on Mindoro.  Heavy rain was falling over over Tablas Island and southeastern Mindoro.

Typhoon Phanfone strengthened slightly even though parts of the eyewall moved over some of the islands in the central Philippines.  The core of Phanfone remained intact and there was a small circular eye at the center of the typhoon.  The strongest winds were occurring in a ring of thunderstorms around the eye.  Winds to typhoon force extended out 25 miles (40 km) from the center of circulation.  Winds to tropical storm force extended out 125 miles (200 km).  The Hurricane Intensity Index (HII) for Typhoon Phanfone was 19.2.  The Hurricane Size Index (HSI) was 8.3 and the Hurricane Wind Intensity Size Index (HWISI) was 27.5.

Typhoon Phanfone will move through an environment favorable for intensification during the next 24 to 36 hours.  Phanfone will move over water where the Sea Surface Temperature is near 29°C.  It will move through a region where the upper level winds are weak and there will be little vertical wind shear.  Typhoon Phanfone could intensify into the equivalent of a major hurricane if the core of the circulation passes south of Mindoro.

Typhoon Phanfone will move south of a subtropical high pressure system over the Western North Pacific Island.  The high will steer Phanfone toward the west-northwest during the next several days.  On its anticipated track the center of Typhoon Phanfone will pass near the southern end of Mindoro during the next few hours.  The center will pass near Busuanga Island and Culion Island before Phanfone moves over the South China Sea.  Typhoon Phanfone will bring strong winds and heavy rain to Roxas, San Jose and Coron.  Heavy rain on Tablas Island, southern Mindoro, Busuanga Island and Culion Island could cause flash floods.  Floods are most likely on southern Mindoro because of the steep slopes near mountains.  Conditions will improve over Panay Island as Phanfone moves farther away.

Strengthening Typhoon Phanfone Makes Landfall in Central Philippines

A strengthening Typhoon Phanfone made landfall in the central Philippines on Tuesday morning.  At 10:00 a.m. EST on Tuesday the center of Typhoon Phanfone was located at latitude 11.6°N and longitude 124.1°E which put it about 30 miles (50 km) southeast of Placer, Philippines.  Phanfone was moving toward the west-northwest at 19 m.p.h. (31 km/h).  The maximum sustained wind speed was 105 m.p.h. (170 km/h) and there were wind gusts to 125 m.p.h. (200 km/h).  The minimum surface pressure was 966 mb.

Typhoon Phanfone strengthened quickly as it made landfall in the central Philippines.  A small circular eye became more distinct on  satellite imagery.  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 120 miles (195 km) from the center.  The Hurricane intensity Index (HII) for Typhoon Phanfone was 17.8.  The Hurricane Size Index (HSI) was 10.8 and the Hurricane Wind intensity Size Index (HWISI) was 28.6.

The center of Typhoon Phanfone made landfall near Guiuan on Samar.  The center of Phanfone passed near Tacloban on Leyte before it moved over the Visayan Sea.  Typhoon Phanfone brought strong winds and heavy rain to Samar and Leyte.  The winds were strong enough to cause serious damage and regional power outages.  The heavy rain could cause flash floods in some locations.

Typhoon Phanfone moved through a favorable environment that allowed to strengthen.  Phanfone moved over water where the Sea Surface Temperature was near 29°C.  It moved through a region where the upper level winds were weak and there was little vertical wind shear.  The core of Phanfone moved quickly over narrow portions of Samar and Leyte and the core remained intact.  Typhoon Phanfone could strengthen while the enter moves across the Visayan Sea and it could intensify into the equivalent of a major hurricane.

Typhoon Phanfone will move south of a subtropical ridge over the Western North Pacific Ocean during the next several days.  The ridge will steer Phanfone toward the west-northwest.  On its anticipated track the center of Typhoon Phanfone will pass near Masbate and the northern end of Panay Island.  Phanfone could be near Mindoro in about 12 hours.  Typhoon Phanfone will bring strong winds and heavy rain to Masbate, the northern end of Panay Island, the northern end of Negros and Mindoro.  Conditions will improve gradually when Phanfone moves away from Samar and Leyte.

Typhoon Kammuri Brings Wind and Rain to Southern Luzon

Typhoon Kammuri brought wind and rain to southern Luzon and Mindoro on Tuesday.  At 10:00 a.m. EST on Tuesday the center of Typhoon Kammuri was located at latitude 13.4°N and longitude 114.9°E which put it about 115 miles (185 km) south-southwest of Manila, Philippines.  Kammuri was moving toward the west at 13 m.p.h. (20 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 976 mb.

Typhoon Kammuri made landfall on the coast of southeastern Luzon near Sorsogon and Legaspi on Nonday.  After making landfall, the eye of Kammuri passed over San Pascual on the northern end of Burias Island.  The center of Kammuri moved across the Sibuyan Sea and the core of the typhoon passed over Marinduque Island and northern Mindoro.  Rainbands in the northern half of Typhoon Kammuri produced strong winds and dropped heavy rain over southern Luzon.  There were reports of widespread power outages.  There were also reports of several deaths associated with the passage of Kammuri.

Typhoon Kammuri weakened slowly as the circulation passed over land.  Increased friction caused the wind speed to gradually decrease and mountains disrupted portions of the circulation.  The eastern side of the eyewall weakened and the eye was no longer apparent on infrared satellite images.  The strongest thunderstorms were occurring in bands west and north of the center of circulation.  Bands southeast of the center consisted primarily of showers and lower clouds.  Winds to typhoon force extended out 60 miles (95 km) from the center of circulation.  Winds to tropical storm force extended out 250 miles (400 km) from the center.

Conditions will improve over southern Luzon and Mindoro as Typhoon Kammuri moves farther away.  Kammuri could maintain its intensity over even strengthen slightly during the next 24 hours as it moves over the warm water in the South China Sea.  Typhoon Kammuri will move over water where the Sea Surface Temperature is near 29°C.  Kammuri will reach the eastern end of a surface high pressure system over eastern Asia in about 24 hours.  Strong northeasterly winds will blow around the eastern end of the high and those winds will create strong vertical wind shear as they blow under southwesterly winds in the upper levels.  The strong wind shear is likely to cause Typhoon Kammuri to weaken quickly in about a day or so.

A ridge over the Western North Pacific Ocean will steer Typhoon Kammuri toward the west for about another 24 hours.  On its anticipated track Kammuri will move farther away from the Philippines.  When Typhoon Kammuri reaches the area of more vertical wind shear and the typhoon weakens, it will be steered by winds closer to the surface.  The strong northeasterly winds in that part of the atmosphere will steer Kammuri toward the south-southwest later this week.

Major Typhoon Kammuri Makes Landfall on Southeastern Luzon

Major Typhoon Kammuri made landfall on southeastern Luzon near Sorsogon and Legaspi on Monday.  At noon EST on Monday the center of Typhoon Kammuri was located at latitude 13.2°N and longitude 123.6°E which put it about 10 miles (15 km) west of Legaspi, Philippines and about 230 miles (370 km) east-southeast of Manila.  Kamuri was moving toward the west at 11 m.p.h. (17 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 950 mb.

Typhoon Kammuri rapidly intensified into the equivalent of a major hurricane during the 12 hours prior to landfall on Monday.  A large eye with a diameter to 50 miles (80 km) developed at the center of Kammuri.  A thick ring of strong thunderstorms surrounded the eye and the strongest winds were occurring in that ring of storms.  Bands of showers and thunderstorms were revolving around the core of the typhoon.  Storms near the core generated strong upper level divergence which pumped mass away from the typhoon in all directions.  The removal of large amounts of mass allowed the surface pressure to decrease more quickly.

Typhoon Kammuri also grew larger as it got stronger.  Winds to typhoon force extended out about 50 miles (80 km) in most portions of Kammuri, but those strong winds extended out 90 miles (145 km) in the northwestern part of the circulation.  Winds to tropical storm force extended out 175 miles (280 km) in most parts of the circulation, but they extended out 300 miles (480 km) to the northwest of the center of Kammuri.  The Hurricane Intensity Index (HII) for Typhoon Kammuri was 25.1.  The Hurricane Size Index (HSI) was 25.4 and the Hurricane Wind Intensity Size Index (HWISI) was 50.5.  Typhoon Kammuri was capable of causing widespread major damage to southern Luzon.

Typhoon Kammuri will move south of a ridge of high pressure over the Western North Pacific Ocean.  The ridge will steer Kammuri toward the west-northwest during the next 36 to 48 hours.  On its anticipated track Typhoon Kammuri will move across southeastern Luzon and over the Sibuyan Sea during the next few hours.  The center of Kammuri is forecast to pass south of Manila in 18 to 24 hours.

Typhoon Kammuri will weaken slowly as it moves across southeastern Luzon.  Kammuri will bring strong winds and heavy rain to southern Luzon.  Typhoon Kammuri will also have a big impact on Burias, Marinduque Island and Mindoro.  Kammuri could produce winds to near typhoon force around Manila.  Typhoon Kammuri is likely to cause major damage around Legaspi.  Locally heavy rain could produce flash floods in numerous locations.  Kammuri could cause serious damage around Manila.

Typhoon Melor Making Landfall on Mindoro as Equivalent of Cat. 4 Hurricane

Typhoon Melor intensified on Monday and it is making landfall on Mindoro in the Philippines as the equivalent of a Category 4 Hurricane on the Saffir-Simpson Scale.  At 10:00 p.m. EST on Monday the center of Typhoon Melor was located at latitude 13.0°N and longitude 121.5°E which put it about 20 miles (32 km) southeast of Calapan and about 125 miles (205 km) south-southeast of Manila, Philippines.  Melor was moving toward the west at 8 m.p.h. (13 km/h).  The maximum sustained wind speed was 140 m.p.h. (230 km/h) and there were wind gusts to 170 m.p.h. (270 km/h).  The minimum surface pressure was 939 mb.

The core of Typhoon Melor passed just north of Samar and it quickly moved over the southeastern tip of Luzon.  Since the core stayed mainly over water, the circulation was not seriously disrupted by the increased friction that would have occurred if it had moved over land.  As a result, the core Typhoon Melor was intact when it moved over the Sibuyan Sea.  The circulation was able to extract energy from the warm water of Sibuyan Sea.  Melor was in an area where the upper level winds were light and there was little vertical wind shear.  The favorable environment allowed the typhoon to intensify further on Monday and Melor reached the equivalent of a Category 4 hurricane.

The center of Typhoon Melor is making a landfall on the northeast coast of Mindoro.  Since the core of Melor will be moving over the island of Mindoro during the next few hours, the typhoon should start to weaken.  Melor will likely still be a typhoon when the center emerges over the South China Sea.  A strong surge of cold, dry air from the north will increase vertical wind shear around Typhoon Melor in 24 to 36 hours.  The dry air and increased wind shear will weaken Melor more rapidly after that occurs.

A subtropical ridge is steering Typhoon Melor toward the west and that general motion is expected to continue for another 24 to 36 hours.  After that time a weakening Melor will be steered by the flow closer to the surface, which should start to push it toward the southwest.

Typhoon Melor will bring very strong winds and heavy rain to Mindoro and southern Luzon.  The core of Melor should stay south of Manila, but locally heavy rain may be possible.  Heavy rain could also cause flooding and mudslides in areas of steep terrain.

Strong Typhoon Melor Along Coast of Samar Heading for SE Luzon

Typhoon Melor reached the Philippines on Sunday and it was moving along the north coast of Samar toward southeastern Luzon.  At 10:00 p.m. EST on Sunday the center of Typhoon Melor was located at latitude 12.6°N and longitude 125.3°E which put it about 20 miles (32 km) north of Laoang, Philippines and about 100 miles (160 km) east-southeast of Legaspi in southeastern Luzon.  Melor was moving toward the west at 13 m.p.h. (21 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 949 mb.

Typhoon Melor has been moving through an environment favorable for intensification.  The Sea Surface Temperatures were near 28°C and there has been little vertical wind shear.  However, the circulation is starting to interact with the Philippines.  The southwestern quarter of the circulation is over Samar.  However, since the core of the circulation is north of the coast of Samar, Melor has remained a strong typhoon.  The circulation of Typhoon Melor is likely to retain much of its integrity until the center makes landfall in southeastern Luzon near Sorsogon.  Melor could remain at typhoon intensity for another 24 hours.  However, eventually the increased friction will slow the portions of the circulation that move over land and Melor will weaken to a tropical storm.

A subtropical ridge is steering Typhoon Melor slightly north of due west and that general motion is expected to continue for several more days.  On its anticipated track the core of Typhoon Melor will pass north of Samar.  It will make landfall on extreme southeastern Luzon near Sorsogon in a few hours.  The center of Melor should pass south of Legaspi before moving over the Sibuyan Sea.  It could move south of Manila in about 36 hours as a tropical storm.

Melor is a strong typhoon and it could bring strong winds and heavy rain to northern Samar, southeastern Luzon, the islands around the Sibuyan Sea and Mindoro.  Heavy rain could cause flooding and trigger mudslides, especially in areas of steep terrain.
