Leave a reply

Former Tropical Storm Kong-rey strengthened to a typhoon over the Western North Pacific Ocean southeast of Taiwan on Monday.  At 5:00 p.m. EDT on Monday the center of Typhoon Kong-rey was located at latitude 17.4°N and longitude 127.6°E which put the center about 690 miles (1115 km) southeast of Taipei, Taiwan.  Kong-rey was moving toward the northwest at 8 m.p.h. (13 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.

Former Tropical Storm Kong-rey strengthened to a typhoon on Monday.  The inner end of a rainband wrapped around the center of Kong-rey’s circulation.  A circular eye was starting to form at the center of Typhoon Kong-rey.  A ring of thunderstorms surrounded the developing eye and the strongest winds were occurring in that ring of storms.  Bands of showers and thunderstorms were revolving around the core of Kong-rey’s circulation.  Storms near the core of Kong-rey generated upper level divergence that pumped mass away from the typhoon.  The removal of mass caused the surface pressure to decrease.

The size of the circulation around Typhoon Kong-rey increased as Kong-rey strengthened.  Winds to typhoon force extended out 105 miles (165 km) on the south side of Kong-rey’s circulation.  Winds to tropical storm force extended out 230 miles (370 km) from the center of Typhoon Kong-rey.

Typhoon Kong-rey will move through an environment favorable for intensification during the next 24 hours.  Kong-rey 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 northeasterly winds that will blow toward the top of Kong-rey’s circulation.  Those winds will cause some vertical wind shear, but the wind shear will not be enough to prevent intensification.  Typhoon Kong-rey will intensify during the next 24 hours.  Kong-rey could strengthen to the equivalent of a major hurricane.

Typhoon Kong-rey will move around the southern part of a high pressure system over the Western North Pacific Ocean.  The high pressure system will steer Kong-rey toward the northwest during the next 24 hours.  On its anticipated track, Typhoon Kong-rey will move closer to Taiwan.  Kong-rey could reach Taiwan later this week.  Typhoon Kong-rey could be the equivalent of a major hurricane when it reaches Taiwan,

Tropical Storm Trami made landfall on the coast of Vietnam early on Sunday.  At 5:00 a.m. EDT on Sunday the center of Tropical Storm Trami was located at latitude 16.0°N and longitude 107.7°E which put the center about 35 miles (55 km) west-northwest of Da Nang, Vietnam.  Trami was moving toward the southwest at 8 m.p.h. (13 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 996 mb.

The center of Tropical Storm Trami made landfall on the coast of Vietnam near Da Nang early on Sunday.  Trami was a relatively small tropical storm at the time of landfall.  Winds to tropical storm force extended out 80 miles (130 km) from the center of Trami’s circulation.

Tropical Storm Trami will move around the southern side of a high pressure system over eastern China.  The high pressure system will steer Trami toward the southwest during the next 24 hours.  On its anticipated track, the center of Tropical Storm Trami will move inland over Southeast Asia.

Tropical Storm Trami will bring gusty winds and locally heavy rain to central Vietnam, southern Laos, northern Cambodia and northeastern Thailand.  Heavy rain is likely to cause floods in some locations.

Elsewhere over the Western North Pacific Ocean, Tropical Storm Kong-rey started to strengthen southeast of Taiwan.  At 5:00 a.m. EDT on Sunday the center of Tropical Storm Kong-rey was located at latitude 16.3°N and longitude 131.6°E which put the center about 680 miles (1095 km) southeast of Taipei, Taiwan.  Kong-rey was moving toward the west at 13 m.p.h. (20 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 994 mb.

Leave a reply

Former Hurricane Kristy weakened to a tropical storm over the Eastern North Pacific Ocean west of Baja California on Saturday.  At 5:00 p.m. EDT on Saturday the center of Tropical Storm Kristy was located at latitude 20.7°N and longitude 129.2°W which put the center about 1245 miles (2005 km) west of the southern tip of Baja California.  Kristy was moving toward the northwest at 14 m.p.h. (22 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 993 mb.

Former Hurricane Kristy moved under the eastern side of an upper level trough east of Hawaii.  The upper level trough produced strong southwesterly winds that blew across the top of Kristy’s circulation.  Those winds caused strong vertical wind shear.  The wind shear blew the tops off of many of the thunderstorms in Tropical Storm Kristy, which caused Kristy to weaken rapidly.

The former eye of then Hurricane Kristy was still visible on satellite images.  However, the eye was surrounded by a ring of low clouds.  A few thunderstorms were still occurring in bands in the northern side of Tropical Storm Kristy.  Most of the bands revolving around the center of Kristy’s circulation consisted primarily of showers and lower clouds.

Despite the strong vertical wind shear, the distribution of wind speeds in Tropical Storm Kristy was fairly symmetrical.  Winds to tropical storm force extended out 115 miles (185 km) from the center of Kristy’s circulation.

Tropical Storm Kristy will move through an environment that will be unfavorable for intensification during the next 24 hours.  Kristy will move over water where the Sea Surface Temperatures are near 25°C.  The upper level trough east of Hawaii will continue to cause strong vertical wind shear.  Tropical Storm Kristy will continue to weaken during the next 24 hours.

The upper level trough east of Hawaii will steer Tropical Storm Kristy toward the northwest during the next 12 hours.  After the last thunderstorms in Kristy’s circulation dissipate, the tropical storm will be steered by the winds in the lower levels of the atmosphere.  A high pressure system over the Eastern North Pacific Ocean will steer Kristy toward the west-southwest on Sunday.  On its anticipated track, Tropical Storm Kristy will remain far from any land area.

Leave a reply

Tropical Storm Trami approached the coast of Vietnam on Saturday.  At 5:00 p.m. EDT on Saturday the center of Tropical Storm Trami was located at latitude 16.9°N and longitude 109.5°E which put the center about 165 miles (265 km) northeast of Da Nang, Vietnam.  Trami was moving toward the west at 10 m.p.h. (16 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 985 mb.

Tropical Storm Trami was weakening as it approached the coast of Vietnam on Saturday.  Trami was moving under the southern part of an upper level ridge over eastern China.  The upper level ridge was producing easterly winds that were blowing toward the top of Trami’s circulation.  Those winds were causing moderate vertical wind shear and the wind shear was causing Tropical Storm Trami to weaken gradually.

The upper level winds were also causing the distribution of thunderstorms in Tropical Storm Trami to be asymmetrical.  Thunderstorms were occurring in bands in the western side of Trami’s circulation.  The bands in the eastern side of Tropical Storm Trami consisted primarily of showers and lower clouds.

Despite the moderate vertical wind shear, the distribution of wind speeds in Tropical Storm Trami was still fairly symmetrical.  Winds to tropical storm force extended out 150 miles (240 km) from the center of Trami’s circulation.

Tropical Storm Trami will move through an environment unfavorable for intensification.  Trami will move over water where the Sea Surface Temperatures are near 29°C.  However, the upper level ridge over eastern China will continue to cause moderate vertical wind shear.  The wind shear will prevent intensification of Tropical Storm Trami.  Trami is likely to continue to weaken gradually during the next 24 hours.

Tropical Storm Trami will move around the southern side of a high pressure system over eastern China.  The high pressure system will steer Trami toward the west-southwest during the next 24 hours.  On its anticipated track, the center of Tropical Storm Trami will make landfall on the coast of Vietnam north of Da Nang in about 24 hours.

Tropical Storm Trami will bring strong winds and heavy rain to central Vietnam.  Heavy rain is likely to cause floods in some locations.

Elsewhere over the Western North Pacific Ocean, Tropical Storm Kong-rey was spinning southeast of Taiwan.  At 5:00 p.m. EDT on Saturday the center of Tropical Storm Kong-rey was located at latitude 16.7°N and longitude 134.0°E which put the center about 830 miles (1335 km) southeast of Taipei, Taiwan.  Kong-rey was moving toward the west 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 990 mb.

Hurricane Kristy weakened over the Eastern North Pacific Ocean on Friday morning,  At 11:00 a.m. EDT on Friday the center of Hurricane Kristy was located at latitude 15.6°N and longitude 124.8°W which put the center about 1085 miles (1750 km) west-southwest of the southern tip of Baja California.  Kristy was moving toward the west-northwest at 14 m.p.h. (22 km/h).  The maximum sustained wind speed was 125 m.p.h. (200 km/h) and there were wind gusts to 150 m.p.h. (240 km/h).  The minimum surface pressure was 952 mb.

Hurricane Kristy weakened over the Eastern North Pacific Ocean on Friday morning after reaching Category 5 on the Saffir-Simpson Scale on Thursday.  Clouds were developing inside the eye at the center of Kristy’s circulation.  The eye was still 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 Hurricane Kristy.  Storms near the core of Kristy’s circulation generated less upper level divergence than they did on Thursday.  The removal of less mass caused the surface pressure to increase.

The circulation around Hurricane Kristy continued to be small.  Winds to hurricane force extended out 30 miles (50 km) from the center of Kristy’s circulation.  Winds to tropical storm force extended out 105 miles (165 km) from the center of Hurricane Kristy.

Hurricane Kristy will move through an environment that will be unfavorable for intensification during the next 24 hours.  Kristy will move over water where the Sea Surface Temperatures are near 27°C.  It will move under the southern end of an upper level trough east of Hawaii.  The upper level trough will produce southwesterly winds that will blow toward the top of Kristy’s circulation.  Those upper level winds will cause the vertical wind shear to increase.  Hurricane Kristy will continue to weaken during the next 24 hours because of the increased vertical wind shear.

Hurricane Kristy will move around the southwestern part of a high pressure system over the Eastern North Pacific Ocean.  The high pressure system will steer Kristy toward the northwest during the next 24 h.  On its anticipated track, Hurricane Kristy will continue to remain far from any land mass.

Leave a reply

Hurricane Kristy intensified to Category 5 on the Saffir-Simpson Scale over the Eastern North Pacific Ocean southwest of Baja California on Thursday afternoon.  At 5:00 p.m. EDT on Thursday the center of Hurricane Kristy was located at latitude 14.2°N and longitude 121.6°W which put the center about 970 miles (1565 km) southwest of the southern tip of Baja California.  Kristy was moving toward the west at 16 m.p.h. (26 km/h).  The maximum sustained wind speed was 160 m.p.h. (260 km/h) and there were wind gusts to 190 m.p.h. (305 km/h).  The minimum surface pressure was 926 mb.

Hurricane Kristy looked like a Category 5 hurricane on visible satellite images on Thursday afternoon.  A circular eye with a diameter of 17 miles (28 km) was at the center of Kristy’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 Hurricane Kristy.  Storms near the core generated strong upper level divergence that pumped large amounts of mass away from the hurricane.  The removal of large amounts of mass caused the surface pressure to decrease.

The circulation around Hurricane Kristy was small.  Winds to hurricane force extended out 25 miles (40 km) from the center of Kristy’s circulation.  Winds to tropical storm force extended out 105 miles (165 km) from the center of Hurricane Kristy.

The Hurricane Intensity Index (HII) for Hurricane Kristy was 35.0.  The Hurricane Size Index (HSI) was 8.2 and the Hurricane Wind Intensity Size Index (HWISI) was 8.2.  Hurricane Kristy is smaller than Hurricane Milton was when Milton was over the Gulf of Mexico.

Hurricane Kristy will move through an environment that will become less favorable for a powerful hurricane during the next 24 hours.  Kristy will move over water where the Sea Surface Temperatures are near 29°C.  It will move toward the southern end of an upper level trough between Hawaii and California.  The upper level trough will produce southwesterly winds that will start to affect Hurricane Kristy on Friday.  Those upper level winds will cause the vertical wind shear to increase.  Hurricane Kristy will start to weaken when the vertical wind shear increases.

Hurricane Kristy will move around the southwestern part of a high pressure system over the Eastern North Pacific Ocean.  The high pressure system will steer Kristy toward the northwest during the next 24 h.  On its anticipated track, Hurricane Kristy will continue to remain far from any land mass.
