Typhoon Fung-wong Intensifies to Equivalent of a Major Hurricane

Typhoon Fung-wong intensified to the equivalent of a major hurricane east of the Philippines on Saturday.  At 4:00 p.m. EST on Saturday the center of Typhoon Fung-wong was located at latitude 14.0°N and longitude 125.8°E which put the center about 190 miles (305 km) east of Daet, Philippines.  Fung-wong was moving toward the west-northwest at 23 m.p.h. (37 km/h).  The maximum sustained wind speed was 125 m.p.h. (200 km/h) and there were wind gusts to 155 m.p.h. (250 km/h).  The minimum surface pressure was 949 mb.

A circular eye was present at the center of Fung-wong’s circulation.  The eye was surrounded by a ring of thunderstorms and the strongest winds were occurring in that ring of storms.  Bands of showers and thunderstorms revolving around the core of Fung-wong’s circulation.  Storms near the core generated strong upper level divergence that pumped mass away from the typhoon.  The removal of mass caused the surface pressure to decrease.

The circulation around Typhoon Fung-wong was very large.  Winds to typhoon force extended out 110 miles (175 km) in the northern half of Fung-wong’s circulation.  Winds to typhoon force extended out 70 miles (110 km) in the southern side of Typhoon Fung-wong.  Winds to tropical storm force extended out 375 miles (605 km) in the northern side of Fung-wong’s circulation.  Winds to tropical storm force extended out 230 miles (370 km) in the southern half of Typhoon Fung-wong.

The Hurricane Intensity Index (HII) for Typhoon Fung-wong is 23.6.  The Hurricane Size index (HSI) is 37.3 and the Hurricane Wind Intensity Size Index (HWISI) 60.9.  Typhoon Fung-wong is similar in intensity to Hurricane Katrina when Katrina hit Mississippi in 2005.  Fung-wong is larger than Katrina was.

Typhoon Fung-wong will move through an environment favorable for intensification during the next 12 hours.  Fung-wong will move over water where the Sea Surface Temperatures are near 29°C.  It will move under the middle of an upper level ridge that is east of the Philippines.  The upper level winds are weak near the middle of the ridge and there will be little vertical wind shear.  There is drier air to the north and west of Typhoon Fung-wong.  However, that drier air is not likely to be pulled into the typhoon during the next 12 hours.  Typhoon Fung-wong could intensify during the next 12 hours.

Typhoon Fung-wong will move around the southern side of a high pressure system that is over the Western North Pacific Ocean.  The high pressure system will steer Fung-wong toward the west-northwest during the next 24 hours.  On its anticipated track, Typhoon Fung-wong will hit northern Luzon in 18 hours.

Typhoon Fung-wong will be the equivalent of a major hurricane when it reaches Luzon.  Fung-wong will bring strong, gusty winds and very heavy rain to Luzon.  Heavy rain will cause widespread flash floods.  Typhoon Fung-wong could also cause a storm surge of up to 14 fee (4 meters) along portions of the coast of Luzon.

Fung-wong Strengthens to a Typhoon

Former Tropical Storm Fung-wong strengthened to a typhoon east of the Philippines on Friday.  At 10:00 a.m. EST on Friday the center of Typhoon Fung-wong was located at latitude 12.1°N and longitude 134.6°E which put the center about 325 miles (525 km) north of Palau.  Fung-wong was moving toward the west-northwest at 14 m.p.h. (22 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 Fung-wong strengthened to a typhoon on Friday.  The inner end of a rainband wrapped around the center of Typhoon Fung-wong.  Most of the thunderstorms were occurring in bands in the southern half of Fung-wong’s circulation.  Bands in the northern half of Fung-wong consisted primarily of showers and thunderstorms.  Storms near the center of Fung-wong generated upper level divergence that pumped mass away from the typhoon.  The removal of mass caused the surface pressure to decrease.

The circulation around Typhoon Fung-wong was large.  Winds to typhoon force extended out 60 miles (95 km) from the center of Fung-wong’s circulation.  Winds to tropical storm force extended out 250 miles (400 km) in the northern side of Typhoon Fung-wong.  Winds to tropical storm force extended out 160 miles (260 km) in the southern half of Fung-wong’s circulation.

Typhoon Fung-wong will move through an environment favorable for intensification during the next 24 hours.  Fung-wong will move over water where the Sea Surface Temperatures are near 29°C.  It will move under the middle of an upper level ridge that is east of the Philippines.  The upper level winds are weak near the middle of the ridge and there will be little vertical wind shear.  There is drier air to the north and west of Typhoon Fung-wong.  However, that drier is will not be pulled into the typhoon during the next day or so.  Typhoon Fung-wong will intensify during the next 24 hours.  Fung-wong is likely to strengthen to the equivalent of a major hurricane during the weekend.

Typhoon Fung-wong will move around the southern side of a high pressure system that is over the Western North Pacific Ocean.  The high pressure system will steer Fung-wong toward the west-northwest during the next 24 hours.  On its anticipated track, Typhoon Fung-wong will be northeast of Samar in 24 hours.  Fung-wong will reach northern Luzon in 48 hours.

Typhoon Fung-wong will be the equivalent of a major hurricane when it reaches Luzon.  Fung-wong will bring strong, gusty winds and heavy rain to Luzon.  Heavy rain will cause widespread flash floods.  Typhoon Fung-wong could also cause a storm surge of up to 14 fee (4 meters) along portions of the coast of Luzon.

Typhoon Kalmaegi Moves over the Sulu Sea

Typhoon Kalmaegi moved over the Sulu Sea on Tuesday.  At 4:00 a.m. EST on Tuesday the center of Typhoon Kalmaegi was located at latitude 10.5°N and longitude 121.3°E which put the center about 130 miles (210 km) east-southeast of Taytay, Philippines.  Kalmaegi was moving toward the west at 16 m.p.h. (26 km/h).  The maximum sustained wind speed was 80 m.p.h. (130 km/h) and there were wind gusts to 100 m.p.h. (160 km/h).  The minimum surface pressure was 985 mb.

Typhoon Kalmaegi weakened as it moved across the central Philippines on Monday.  An eye was no longer visible on satellite images.  Thunderstorms were still occurring near the center of Kalmaegi’s circulation.  Thunderstorms were also occurring in bands in the southern half of Typhoon Kalmaegi.  Bands in the northern half of Kalmaegi’s circulation contained fewer thunderstorms.  Storms near the center of Kalmaegi still generated upper level divergence that pumped mass away to the west of the typhoon.  However, there was more mass converging in the lower levels of the atmosphere than there was mass diverging in the upper levels.  So, the surface pressure was increasing.

The size of the circulation around Typhoon Kalmaegi decreases as Kalmaegi weakened.  Winds to typhoon force extended out 30 miles (50 km) from the center of Kalmaegi’s circulation.  Winds to tropical storm force extended out 110 miles (170 km) from the center of Typhoon Kalmaegi.

Typhoon Kalmaegi will move through an environment somewhat favorable for intensification during the next 24 hours.  Kalmaegi will move over water where the Sea Surface Temperatures are near 29°C.  It will move under the southern part of an upper level ridge over the Western North Pacific Ocean.  The upper level ridge will produce easterly winds that will blow toward the top of Kalmaegi’s circulation.  Those winds will cause some vertical wind shear.  The vertical wind shear will inhibit intensification but the wind shear may not be enough to prevent intensification.  Typhoon Kalmaegi could start to intensify again during the next 24 hours.

Typhoon Kalmaegi will move around the southern side of a high pressure system over the Western North Pacific Ocean.  The high pressure system will steer Kalmaegi toward the west-northwest during the next 24 hours.  On its anticipated track, Typhoon Kalmaegi will pass near northern Palawan in a few hours.  Kalmaegi will move over the South China Sea on Tuesday night.

Typhoon Kalmaegi will bring strong winds and locally heavy rain to northern Palawan and the Calamian Group of islands.  Heavy rain is likely to cause flash floods in some locations.

Elsewhere over the Western North Pacific Ocean, Tropical Depression 32W formed south of the Marianas.  At 4:00 a.m. EST on Tuesday the center of Tropical Depression 32W was located at latitude 9.5°N and longitude 142.7°E which put the center about 285 miles (460 km) south-southwest of Guam.  The tropical depression was moving toward the west at 11 m.p.h. (17 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.  It is forecast to strengthen.

Typhoon Kalmaegi Brings Wind and Rain to the Philippines

Typhoon Kalmaegi brought wind and rain to parts of the Philippines on Monday.  At 10:00 a.m. EST on Monday the center of Typhoon Kalmaegi was located at latitude 10.6°N and longitude 125.6°E which put the center about 50 miles (80 km) east of Abuyog, Philippines.  Kalmaegi was moving toward the west at 16 m.p.h. (26 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 968 mb.

Typhoon Kalmaegi continued to strengthen as it approached the central Philippines on Monday.  A small circular eye developed at the center of Kalmaegi’s circulation.  The eye was surrounded by a ring of thunderstorms and the strongest winds were occurring in that ring of storms.  Bands of showers and thunderstorms were revolving around the core of Typhoon Kalmaegi.  Storms neat the center of Kalmaegi generated upper level divergence that pumped mass away from the typhoon.  The removal of mass caused the surface pressure to decrease.

The distribution of wind speeds around Typhoon Kalmaegi was symmetrical.  Winds to typhoon force extended out 35 miles (55 km) from the center of Kalmaegi’s circulation.  Winds to tropical storm force extended out 125 miles (200 km) from the center of Typhoon Kalmaegi.

The Hurricane Intensity Index (HII) for Typhoon Kalmaegi was 17.8.  The Hurricane Size Index (HSI) was 13.7 and the Hurricane Wind Intensity Size Index (HWISI) was 31.5.  Typhoon Kalmaegi was similar in size and intensity to Hurricane Sally when Sally hit South Alabama in 2020.

Typhoon Kalmaegi will weaken when the center of circulation passes over the central Philippines.  Kalmaegi will move into an environment favorable for intensification when it reaches the Sulu Sea on Tuesday.  Kalmaegi will move over water where the Sea Surface Temperatures are near 29°C.  It will move under the southern part of an upper level ridge over the Western North Pacific Ocean.  The upper level ridge will produce easterly winds that will blow toward the top of Kalmaegi’s circulation.  Those winds will cause some vertical wind shear, but the wind shear will not be enough to prevent intensification.  Typhoon Kalmaegi will start to intensify again when it reaches the Sulu Sea.

Typhoon Kalmaegi will move around the southern side of a high pressure system over the Western North Pacific Ocean.  The high pressure system will steer Kalmaegi toward the west during the next 24 hours.  On its anticipated track, Typhoon Kalmaegi will move through the central Philippines during the next 24 hours.  The center of Kalmaegi will pass near southern Leyte, Bohol, Cebu, northern Negros, and Panay Island.  Typhoon Kalmaegi will pass near northern Palawan on Tuesday.

Typhoon Kalmaegi will bring strong winds and heavy rain to the central Philippines.  The strongest winds and heaviest rain will occur at Dinagat Island, southern Leyte, Bohol, Cebu, northern Negros, Panay Island, and northern Palawan.  Heavy rain is likely to cause flash floods in some locations.  Typhoon Kalmaegi could also cause a storm surge of up to 10 feet (3 meters) along the coast.

Kalmaegi Strengthens to a Typhoon

Former Tropical Storm Kalmaegi strengthened to a typhoon east of the Philippines on Sunday.  At 10:00 p.m. EST on Sunday the center of Typhoon Kalmaegi was located at latitude 10.5°N and longitude 128.3°E which put the center about 190 miles (305 km) east-northeast of Dinagat, Philippines.  Kalmaegi was moving toward the west-southwest at 15 m.p.h. (24 km/h).  The maximum sustained wind speed was 80 m.p.h. (130 km/h) and there were wind gusts to 100 m.p.h. (160 km/h).  The minimum surface pressure was 985 mb.

Tropical Storm Kalmaegi is likely to be a typhoon when it reaches the Philippines.  Kalmaegi will bring strong winds and heavy rain to the central Philippines.  Heavy rain is likely to cause flash floods in some locations.

Tropical Storm Fengshen Brings Wind and Rain to Philippines

Tropical Storm Fengshen brought wind and rain to the Philippines on Saturday.  At 5:00 p.m. EDT on Saturday the center of Tropical Storm Fengshen was located at latitude 14.3°N and longitude 122.0°E which put the center about 115 miles (185 km) east-southeast of Manila, Philippines.  Fengshen was moving toward the west-northwest at 14 m.p.h. (22 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 998 mb.

Tropical Storm Fengshen was maintaining its intensity as it brought wind and rain to the Philippines on Saturday.  Bands of showers and thunderstorms were dropping heavy rain on parts of Luzon.  Those same bands of thunderstorms were also producing gusty winds.

The strongest winds were occurring in the eastern side of Tropical Storm Fengshen.  Winds to tropical storm force extended out 90 miles (145 km) in the eastern half of Fengshen’s circulation.  The winds in the western side of Tropical Storm Fengshen were blowing at less than tropical storm force.

Tropical Storm Fengshen will move into an environment favorable for intensification when it moves over the South China Sea on Sunday.  Fengshen will move over water where the Sea Surface Temperatures are near 29°C. It will move under the middle of an upper level ridge that is over the Western North Pacific Ocean.  The upper level winds are weak near the middle of the ridge and there will be little vertical wind shear.  Tropical Storm Fengshen is likely to maintain its intensity during the next 12 hours while it moves across Luzon.  Fengshen will intensify when it moves over the South China Sea on Sunday.

Tropical Storm Fengshen will move through an environment favorable for intensification during the next 24 hours.  Fengshen will move over water where the Sea Surface Temperatures are near 30°C.  It will move under the southern part of an upper level ridge that is south of Japan.  The upper level ridge will produce easterly winds that will blow toward the top of Fengshen’s circulation.  Those winds will cause some vertical wind shear.  The vertical wind shear will inhibit intensification, but the wind shear will not be enough to prevent intensification.  Tropical Storm Fengshen will intensify during the next 24hours.

Tropical Storm Fengshen will move around the southern side of a high pressure system that is over the Western North Pacific Ocean.  The high pressure system will steer Fengshen toward the west-northwest during the next 24 hours.  On its anticipated track, Tropical Storm Fengshen will move near the coast of southeastern Luzon on Saturday.

Tropical Storm Fengshen will bring strong winds and locally heavy rain to Luzon.  Heavy rain is likely to cause flash floods in some locations.

Tropical Storm Matmo Moves over South China Sea

Tropical Storm Matmo moved over the South China Sea on Friday morning after crossing northern Luzon.  At 11:00 a.m. EDT on Friday the center of Tropical Storm Matmo was located at latitude 17.7°N and longitude 118.7°E which put the center about 120 miles (195 km) west of Vigan, Philippines.  Matmo was moving toward the west-northwest at 17 m.p.h. (28 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 993 mb.

Former Typhoon Matmo weakened back to a tropical storm after it moved across northern Luzon.  A circular eye was still visible at the center of Matmo’s circulation on satellite images.  The eye was surrounded by a broken ring of thunderstorms and the strongest winds were occurring in that ring of storms.  Bands of showers and thunderstorms were revolving around the center of Matmo’s circulation.  Storms near the center of Matmo generated upper level divergence that pumped mass away from the tropical storm.

The circulation around Tropical Storm Matmo was symmetrical.  Winds to tropical storm force extended out 120 miles (195 km) from the center of Matmo’s circulation.

Tropical Storm Matmo will move through an environment favorable for intensification during the next 24 hours.  Matmo will move over water where the Sea Surface Temperatures are near 29°C.  It will move under the southern part of an upper level ridge that is over China.  The upper level ridge will produce easterly winds that will blow toward the top of Matmo’s circulation.  Those winds will cause some vertical wind shear, but the wind shear will not be enough to prevent intensification.  Tropical Storm Matmo will intensify during the next 24hours.  Matmo is likely to strengthen back to a typhoon later today.

Tropical Storm Matmo will move around the southern side of a high pressure system that is over southern China.  The high pressure system will steer Matmo toward the west-northwest during the next 24 hours.  On its anticipated track, Tropical Storm Matmo will pass south of Hong Kong in 24 hours. Matmo will be near Hainan in 36 hours.

Typhoon Matmo Brings Wind and Rain to Luzon

Typhoon Matmo brought strong winds and rain to Luzon on Thursday night.  At 11:00 p.m. EDT on Thursday the center of Typhoon Matmo was located at latitude 16.6°N and longitude 119.6°E which put the center about 25 miles (40 km) southeast of Canayan, Philippines.  Matmo was moving toward the west-northwest at 14 m.p.h. (22 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 989 mb.

Former Tropical Storm Matmo strengthened to a typhoon as it approached Luzon on Thursday.  The inner end of a rainband wrapped most of the way around the center of Matmo’s circulation.  An eye started to form at the center of Typhoon Matmo before if made landfall in Luzon.  The eye was surrounded by a ring of thunderstorms and the strongest winds were occurring in that ring of storms.  Bands of showers and thunderstorms were revolving around the center of Matmo’s circulation.  Storms near the center of Matmo generated upper level divergence that pumped mass away from the typhoon.  The removal of mass caused the surface pressure to decrease.

The circulation around Typhoon Matmo was small.  Winds to typhoon force extended out 20 miles (30 km) from the center of Matmo’s circulation.  Winds to tropical storm force extended out 120 miles (195 km) from the center of Typhoon Matmo.

Typhoon Matmo will weaken slightly while it moves across northern Luzon during the next few hours.  Matmo will move into an environment favorable for intensification when it moves over the South China Sea on Friday.  Matmo will move over water where the Sea Surface Temperatures are near 29°C.  It will move under the southern part of an upper level ridge over the Western North Pacific Ocean.  The upper level ridge will produce easterly winds that will blow toward the top of Matmo’s circulation.  Those winds will cause some vertical wind shear, but the wind shear will not be enough to prevent intensification. Typhoon Matmo will start to intensify again when it moves over the South China Sea.

Typhoon Matmo will move around the southern side of a high pressure system that is south of Japan.  The high pressure system will steer Matmo toward the west-northwest during the next 24 hours.  On its anticipated track, Typhoon Matmo will move across northern Luzon during the next few hours.  Matmo will move over the South China Sea on Friday.

Typhoon Matmo will cause strong winds and heavy rain in northern Luzon.  The strong winds could cause electricity outages.  Heavy rain is likely to cause flash floods in some location. Typhoon Matmo could also cause a storm surge of up to 7 feet (2 meters).
