Typhoon Kalmaegi Strikes Central Vietnam

Typhoon Kalmaegi struck central Vietnam on early on Thursday.  At 4:00 a.m. EST on Thursday the center of Typhoon Kalmaegi was located at latitude 13.6°N and longitude 109.9°E which put the center about 50 miles (80 km) southeast of Quy Nohn, Vietnam.  Kalmaegi was moving toward the west-northwest at 17 m.p.h. (28 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 951 mb.

The center of Typhoon Kalmaegi made landfall on the coast of central Vietnam near Song Cau early on Thursday.  Kalmaegi was the equivalent of a major hurricane at the time of landfall.  The maximum sustained wind speed was 125 m.p.h. (200 km/h) at the time of landfall.

At the time of landfall winds to typhoon force extended out 45 miles (75 km) from the center of Kalmaegi’s circulation.  Winds to tropical storm force extended out 160 miles (260 km) from the center center of Typhoon Kalmaegi.

The Hurricane Intensity Index (HII) for Typhoon Kalmaegi at the time of landfall was 23.6.  The Hurricane Size Index (HSI) was 18.4 and the Hurricane Wind Intensity Size Index (HWISI) was 42.0.  Typhoon Kalmaegi was similar in size and intensity to Hurricane Milton when Milton hit Florida in 2024.

Typhoon Kalmaegi will move around the southern side of a high pressure system that is over China.  The high pressure system will steer Kalmaegi toward the west during the next 24 hours.  On its anticipated track, Typhoon Kalmaegi will move inland over central Vietnam during the next few hours.  Kalmaegi will then move near the border between Laos and Cambodia.

Typhoon Kalmaegi will continue to bring strong winds and heavy rain to central Vietnam during the next few hours.  Heavy rain will cause flash floods in some locations.

Typhoon Kalmaegi will weaken steadily as it moves farther inland over Southeast Asia.  Kalmaegi will also drop heavy rain over southern Laos, Cambodia, and northern Thailand.

Elsewhere over the Western North Pacific Ocean, Tropical Storm Fung-wong continued to strengthen gradually east of Yap.  At 4:00 a.m. EST on Thursday the center of Tropical Storm Fung-wong was located at latitude 9.9°N and longitude 140.62E which put the center about 170 miles (280 km) east of Yap.  Fung-wong was moving toward the west-northwest at 3 m.p.h. (5 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 992 mb.  Tropical Storm Fung-wong is forecast to intensify to a typhoon.

Typhoon Kalmaegi Intensifies to Equivalent of a Major Hurricane

Typhoon Kalmaegi intensified to the equivalent of a major hurricane east of Vietnam on Wednesday.  At 4:00 p.m. EST on Wednesday the center of Typhoon Kalmaegi was located at latitude 13.4°N and longitude 113.6°E which put the center about 335 miles (540 km) east-southeast of Quy Nohn, Vietnam.  Kalmaegi was moving toward the west-northwest at 21 m.p.h. (33 km/h).  The maximum sustained wind speed was 115 m.p.h. (185 km/h) and there were wind gusts to 145 m.p.h. (235 km/h).  The minimum surface pressure was 960 mb.

Typhoon Kalmaegi continued to strengthen on Wednesday as it moved over the South China Sea east of Vietnam.  A small circular eye was 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 center of Typhoon Kalmaegi.  Storms near 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 circulation around Typhoon Kalmaegi was relatively small. Winds to typhoon force extended out 30 miles (50 km) from the center of Kalmaegi’s circulation. Winds to tropical storm force extended out 115 miles (185 km) from the center of Typhoon Kalmaegi.

The Hurricane Intensity Index (HII) for Typhoon Kalmaegi was 20.6.  The Hurricane Size Index (HSI) was 12.5 and the Hurricane Wind Intensity Size Index (HWISI) was 33.1.  Typhoon Kalmaegi was similar in size and intensity to Hurricane Delta when Delta hit Louisiana in 2020.

Typhoon Kalmaegi will move through an environment somewhat favorable for intensification during the next 18 hours.  Kalmaegi will move over water where the Sea Surface Temperatures are near 28°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 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.  There is drier air to the north of Kalmaegi.  Typhoon Kalmaegi could intensify during the next 18 hours if the drier air remains north of the typhoon.

Typhoon Kalmaegi will move around the southern side of a high pressure system that is over China.  The high pressure system will steer Kalmaegi toward the west-northwest during the next 24 hours.  On its anticipated track, Typhoon Kalmaegi will reach the coast of central Vietnam in 18 hours.

The center of Typhoon Kalmaegi is likely to make landfall on the coast of Vietnam near Quy Nohn.  Kalmaegi will bring strong winds and heavy rain to central Vietnam.  Heavy rain will cause flash floods in some locations.  Typhoon Kalmaegi could also cause a storm surge of up to 10 feet (3 meters) along parts of the coast.

Typhoon Kalmaegi will also drop heavy rain over southern Laos, Cambodia, and northern Thailand.

Elsewhere over the Western North Pacific Ocean, former Tropical Depression 32W strengthened to Tropical Storm Fung-wong east of Yap.  At 4:00 p.m. EST on Wednesday the center of Tropical Storm Fung-wong was located at latitude 9.7°N and longitude 140.6°E which put the center about 190 miles (305 km) east of Yap.  Fung-wong 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 996 mb.  Tropical Storm Fung-wong is forecast to intensify to a typhoon.

Typhoon Kalmaegi Moves over South China Sea

Typhoon Kalmaegi moved over the South China Sea on Wednesday.  At 10:00 a.m. EST on Wednesday the center of Typhoon Kalmaegi was located at latitude 12.7°N and longitude 115.2°E which put the center about 450 miles (725 km) east-southeast of Quy Nohn, Vietnam.  Kalmaegi was moving toward the west-northwest at 14 m.p.h. (22 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 970 mb.

Typhoon Kalmaegi strengthened again on Wednesday as it moved over the South China Sea.  A new, small circular eye formed 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 center of Typhoon Kalmaegi.  Storms near 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 circulation around Typhoon Kalmaegi was relatively small.  Winds to typhoon force extended out 35 miles (55 km) from the center of Kalmaegi’s circulation.  Winds to tropical storm force extended out 140 miles (225 km) from the center of Typhoon Kalmaegi.

The Hurricane Intensity Index (HII) for Typhoon Kalmaegi was 17.8.  The Hurricane Size Index (HSI) was 12.0 and the Hurricane Wind Intensity Size Index (HWISI) was 29.8.  Typhoon Kalmaegi was similar in size and intensity to Hurricane Sally when Sally hit South Alabama in 2020.
