Tropical Storm Fausto Passes Northeast of Hawaii

Leave a reply

Tropical Storm Fausto was weakening as it passed northeast of Hawaii on Tuesday.  At 5:00 p.m. EDT on Tuesday the center of Tropical Storm Fausto was located at latitude 22.5°N and longitude 152.2°W which put the center about 270 miles (435 km) northeast of Hilo, Hawaii.  Fausto was moving toward the west-northwest at 12 m.p.h. (19 km/h).  The maximum sustained wind speed was 50 m.p.h. (80 km/h) and there were wind gusts to 65 m.p.h. (105 km/h).  The minimum surface pressure was 1005 mb.

Tropical Storm Fausto was weakening as it passed northeast of Hawaii on Tuesday afternoon.  An upper level trough that was located north of Hawaii was producing strong southwesterly winds that were blowing across the top of Fausto’s circulation.  Those winds were causing strong vertical wind shear.  The strong upper level winds were also blowing the tops off of many of the thunderstorms in Tropical Storm Fausto.

Thunderstorms were still occurring in bands in the eastern edge of Tropical Storm Fausto.  Bands in the other parts of Fausto’s circulation consisted primarily of showers and lower clouds.  There were no thunderstorms near the center of Fausto to generate upper level divergence to pump mass away from the tropical storm.  Convergence of mass in the lower levels of the atmosphere was causing the surface pressure to increase.

The strongest winds were blowing on the northern side of Tropical Storm Fausto.  Winds to tropical storm force extended out 140 miles (220 km) in the northern side of Fausto’s circulation.  Winds to tropical storm force only extended out 70 miles (110 km) in the southern side of Tropical Storm Fausto.

Tropical Storm Fausto will move through an environment that will be unfavorable for intensification during the next 24 hours.  Fausto will move over water where the Sea Surface Temperatures are near 26°C.  However, the upper level trough north of Hawaii will continue to cause strong vertical wind shear.  Tropical Storm Fausto will continue to weaken steadily during the next 24 hours.  Fausto is likely to weaken to a tropical depression on Wednesday.

Tropical Storm Fausto will move around the southern side of a high pressure system that is over the Central North Pacific Ocean.  The high pressure system will steer Fausto toward the west-northwest during the next 24 hours.  On its anticipated track, Tropical Storm Fausto will continue to pass north of Hawaii on Wednesday.

Elsewhere, Hurricane Genevieve was weakening gradually as it move southwest of Baja California.  At 5:00 p.m. EDT on Tuesday the center of Hurricane Genevieve was located at latitude 18.0°N and longitude 116.9°W which put the center about 565 miles (910 km) southwest of southern tip of Baja California.  Genevieve was moving toward the west-northwest at 9 m.p.h. (15 km/h).  The maximum sustained wind speed was 120 m.p.h. (195 km/h) and there were wind gusts to 140 m.p.h. (220 km/h). The minimum surface pressure was 955 mb.

Typhoon Dolphin rapidly intensified to the equivalent of a major hurricane as it moved over the Western North Pacific Ocean southeast of Wake Island.  At 11:00 a.m. EDT on Tuesday the center of Typhoon Dolphin was located at latitude 13.6°N and longitude 170.3°E which put the center about 490 miles (790 km) southeast of Wake Island.  Dolphin was moving toward the west at 12 m.p.h. (19 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. (2350 km/h).  The minimum surface pressure was 960 mb.

Typhoon Dolphin rapidly intensified to the equivalent of a major hurricane on Tuesday morning.  A very small circular eye was present at the center of Dolphin’s circulation.  The eye was surrounded by a ring of thunderstorms.  The strongest winds were occurring in that ring of storms.  Bands of showers and thunderstorms revolved around the core of Typhoon Dolphin.  Storms near the core of Dolphin generated strong upper level divergence that pumped large amounts of mass from the typhoon.  The removal of large amounts of mass caused the surface pressure to decrease rapidly.

The circulation around Typhoon Dolphin was small.  Winds to typhoon force extended out 20 miles (30 km) from the center of Dolphin’s circulation.  Winds to tropical storm force extended out 80 miles (130 km) from the center of Typhoon Dolphin.

Typhoon Dolphin will move through an environment that will be very favorable for intensification during the next 24 hours.  Dolphin 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.  Typhoon Dolphin will intensify during the next 24 hours.  Dolphin could continue to intensify rapidly during the next few hours.  Typhoon Dolphin is likely to strengthen to the equivalent of a Category 5 hurricane on the Saffir-Simpson Scale on Thursday.

Typhoon Dolphin 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 Dolphin toward the west-northwest during the next 24 hours.  On its anticipated track, the center of Typhoon Dolphin will pass south of Wake Island on Wednesday.

Typhoon Noul will move around the southwestern part of a high pressure system that is over the Western North Pacific Ocean.  The high pressure system will steer Noul toward the northwest during the next 24 hours.  On its anticipated track, the center of Typhoon Noul will make landfall on the coast of southeastern China northeast of Hong Kong in 15 hours.

Typhoon Noul will bring strong winds and locally heavy rain to eastern Guangdong, southern Fujian, and Jiangxi.  Heavy rain is likely to cause flash floods in some locations.  Typhoon Noul could cause a storm surge of up to 12 feet (3.6 meters) along parts of the coast of southeastern China.

Hurricane Fausto Strengthens a Little More

Leave a reply

Hurricane Fausto strengthened a little more on Friday morning as it moved toward the Central Pacific Ocean.  At 11:00 a.m. EDT on Friday the center of Hurricane Fausto was located at latitude 18.6°N and longitude 131.2°W which put the center about 1560 miles (2510 km) east of Hilo, Hawaii.  Fausto 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 967 mb.

Hurricane Fausto continued to strengthen early on Friday.  A circular eye with a diameter of 17 miles (28 km) was at the center of Fausto’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 Fausto’ circulation.  Storms near the center of Fausto generated more upper level divergence that pumped more mass away from the hurricane.  The removal of more mass caused the surface pressure to decrease.

The distribution of wind speeds around Hurricane Fausto became more symmetrical on Friday.  Winds to hurricane force extended out 45 miles (75 km) from the center of Fausto’s circulation.  Winds to tropical storm force extended out 185 miles (295 km) from the center of Hurricane Fausto.

Hurricane Fausto will move into an environment that will become unfavorable for intensification during the next 24 hours.  Fausto will move over water where the Sea Surface Temperatures are near 26°C.  It will move under the middle of an upper level ridge that is southwest of Mexico.  The upper level winds are weak near the middle of the ridge and there will be little vertical wind shear.  There is drier air just to the north and west of Hurricane Fausto.  The drier air is likely to inhibit the development of new thunderstorms in bands in the northern and western parts of Fausto’s circulation.  Hurricane Fausto is likely to weaken during the next 24 hours because of the effects of the drier air.

Hurricane Fausto will move around the southern part of a high pressure system that is over the Eastern North Pacific Ocean.  The high pressure system will steer Fausto toward the west during the next 24 hours.  On its anticipated track, Hurricane Fausto will continue to move toward the Central Pacific Ocean.  Fausto could be near the Hawaiian Islands by the middle of next week.

Elsewhere over the Eastern North Pacific Ocean, Tropical Depression Seven-E formed south of Mexico.  At 11:00 a.m. EDT on Friday the center of Tropical Depression Seven-E was located at latitude 9.0°N and longitude 100.5°W which put the center about 605 miles (975 km) south of Zihuatanejo, Mexico.  The tropical depression was moving toward the west-northwest at 12 m.p.h. (19 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 1005 mb.
