Tropical Storm Juliette Weakens

Tropical Storm Juliette weakened as it moved west of Baja California on Wednesday.  At 5:00 p.m. EDT on Wednesday the center of Tropical Storm Juliette was located at latitude 23.9°N and longitude 120.2°W which put the center about 655 miles (1055 km) west of the southern tip of Baja California.  Juliette was moving toward the north-northwest at 14 m.p.h. (22 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 1006 mb.

A combination of cooler water and stronger vertical wind shear caused Tropical Storm Juliette to weaken on Wednesday.  Thunderstorms were still occurring in bands in the northeastern part of Juliette’s circulation.  Bands in the other parts of Tropical Storm Juliette consisted primarily of showers and lower clouds.

The circulation around Tropical Storm Juliette was small.  Winds to tropical storm force extended out 45 miles (75 km) from the center of Juliette’s circulation.

Tropical Storm Juliette will move through an environment that will be unfavorable for intensification during the next 24 hours.  Juliette will move over water where the Sea Surface Temperatures are near 22°C.  It will move under the eastern part of an upper level trough that is west of Baja California.  The upper level trough will produce southwesterly winds that will blow toward the top of Juliette’s circulation.  Those winds will cause strong vertical wind shear.  The combination of cool Sea Surface Temperatures and strong vertical wind shear will cause Tropical Storm Juliette to continue to weaken during the next 24 hours.

The upper level trough west of Baja California will steer Tropical Storm Juliette toward the north during the next 24 hours.  On its anticipated track, Tropical Storm Juliette will remain far to the west of Baja California.

Tropical Storm Juliette Moves Southwest of Baja California

Tropical Storm Juliette moved southwest of Baja California on Tuesday.  At 5:00 p.m. EDT on Tuesday the center of Tropical Storm Juliette was located at latitude 19.9°N and longitude 117.2°W which put the center about 515 miles (825 km) west-southwest of the southern tip of Baja California.  Juliette was moving toward the northwest at 10 m.p.h. (16 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 996 mb.

Tropical Storm Juliette intensified on Tuesday as it moved over the Eastern North Pacific Ocean southwest of Baja California.  More thunderstorms formed near the center of Juliette’s circulation.  Thunderstorms were also occurring in bands in the southern half of Tropical Storm Juliette.  Bands in the northern side of Juliette’s circulation consisted primarily of showers and lower clouds.  Storms near the center of Juliette generated upper level divergence that pumped mass away to the south and west of the tropical storm.

The circulation around Tropical Storm Juliette was small.  Winds to tropical storm force extended out 70 miles (110 km) from the center of Juliette’s circulation.

Tropical Storm Juliette will move through an environment unfavorable for intensification during the next 24 hours.  Juliette will move over water where the Sea Surface Temperatures are near 24°C.  It will move under the southeastern part of an upper level ridge over the Eastern North Pacific Ocean.  The upper level ridge will produce northeasterly winds that will blow toward the top of Juliette’s circulation.  Those winds will cause moderate vertical wind shear.  The combination of cooler Sea Surface Temperatures and moderate vertical wind shear will cause Tropical Storm Juliette to weaken during the next 24 hours.

Tropical Storm Juliette will move around the western end of a high pressure system over northwestern Mexico.  The high pressure system will steer Juliette toward the northwest during the next 24 hours.  On its anticipated track, Tropical Storm Juliette will remain far to the west of Baja California.

Tropical Storm Juliette Forms South of Baja California

Tropical Storm Juliette formed over the Eastern North Pacific Ocean south of Baja California early on Monday.  At 5:00 a.m. EDT on Monday the center of Tropical Storm Julliette was located at latitude 16.8°N and longitude 111.8°W which put the center about 440 miles (770 km) south-southwest of the southern tip of Baja California.  Juliette was moving toward the west-northwest at 13 m.p.h. (21 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 1003 mb.

A low pressure system over the Eastern North Pacific Ocean south of Baja California strengthened early on Monday and the U.S. National Hurricane Center designated the system as Tropical Storm Juliette.

More thunderstorms were developing near the center of Tropical Storm Juliette on Monday morning.  Thunderstorms were also forming in bands revolving around the center of Juliette’s circulation.  Storms near the center of Juliette began to generate upper level divergence that pumped mass away from the tropical storm.  The removal of mass caused the surface pressure to decrease.

The strongest winds were occurring in the northern side of Tropical Storm Juliette.  Winds to tropical storm force extended out 50 miles (80 km) in the northern side of Juliette’s circulation.  The winds in the southern side of Tropical Storm Juliette were blowing at less than tropical storm force.

Tropical Storm Juliette will move through an environment favorable for intensification during the next 24 hours.  Juliette will move over water where the Sea Surface Temperatures are near 28°C.  It will move under the southwestern part of an upper level ridge centered over Mexico.  The upper level ridge will produce easterly winds that will blow toward the top of Juliette’s circulation.  Those winds will cause some vertical wind shear, but he wind shear will not be enough to prevent intensification.  Tropical Storm Juliette will intensify during the next 24 hours.

Tropical Storm Juliette will move around the southern side of a high pressure system over the Eastern North Pacific Ocean.  The high pressure system will steer Juliette toward the west-northwest during the next 24 hours.  On its anticipated track, Tropical Storm Juliette will move southwest of Baja California.

 

Henriette Rapidly Intensifies to a Hurricane

Former Tropical Storm Henriette rapidly intensified to a hurricane northeast of Hawaii on Sunday.  At 5:00 p.m. EDT on Sunday the center of Hurricane Henriette was located at latitude 25.7°N and longitude 152.5°W which put the center about 455 miles (735 km) northeast of Honolulu, Hawaii.  Henriette was moving toward the northwest at 17 m.p.h. (28 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 990 mb.

Former Tropical Storm Henriette rapidly intensified to a hurricane northeast of Hawaii on Sunday.  The inner end of a rainband wrapped around the center of Henriette’s circulation.  A circular eye with a diameter of 15 miles (24 km) formed at the center of Hurricane Henriette.  The eye was surrounded by a ring of thunderstorms and the strongest winds were occurring in that rings of storms.  Bands of showers and thunderstorms were revolving around the center of Henriette’s circulation.  Storms near the center of Henriette generated upper level divergence that pumped mass away from the hurricane.  The removal of mass caused the surface pressure to decrease.

The circulation around Hurricane Henriette was small.  Winds to hurricane force extended out 20 miles (30 km) from the center of Henriette’s circulation.  Winds to tropical storm force extended out 70 miles (110 km) from the center of Hurricane Henriette.

Hurricane Henriette will move through an environment favorable for intensification during the next 24 hours.  Henriette will move over water where the Sea Surface Temperatures are near 26°C.  It will move under the middle of an upper level trough that is east of Hawaii.  The upper level winds are weak near the middle of the trough and there will be little vertical wind shear. Hurricane Henriette will intensify during the next 24 hours.  Henriette could continue to intensify rapidly.

Hurricane Henriette will move around the southwestern part of a high pressure system over the central North Pacific Ocean.  The high pressure system will steer Henriette toward the northwest during the next 24 hours.  On its anticipated track, Hurricane Henriette will pass well to the north of Hawaii.

Elsewhere, Tropical Storm Ivo continued to churn west of Baja California. At 5:00 p.m. EDT on Sunday the center of Tropical Storm Ivo was located at latitude 22.1°N and longitude 117.2°W which put the center about 470 miles (755 km) west of the southern tip of Baja California.  Ivo was moving toward the west-northwest at 12 m.p.h.

Tropical Storm Henriette Passes Northeast of Hawaii

Tropical Storm Henriette was passing northeast of Hawaii on Sunday.  At 5:00 a.m. EDT on Sunday the center of Tropical Storm Henriette was located at latitude 23.8°N and longitude 150.3°W which put the center about 420 miles (675 km) northeast Hilo, Hawaii.  Henriette was moving toward the northwest at 15 m.p.h. (24 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 1006 mb.

Former Tropical Storm Henriette strengthened back to a tropical storm as it moved northeast of Hawaii on Sunday.  More thunderstorms former near the center of Henriette’s circulation.  The inner end of a rainband wrapped much of the way around the center of Tropical Storm Henriette.  A clear area was forming at the center of Henriette.  Storms near the center of Henriette generated upper level divergence that pumped mass away from the tropical storm.

The circulation around Tropical Storm Henriette was small.  Winds to tropical storm force extended out 105 miles (165 km) from the center of Henriette’s circulation.

Tropical Storm Henriette will move through an environment favorable for intensification during the next 24 hours.  Henriette will move over water where the Sea Surface Temperatures are near 26°C.  It will move under the middle of an upper level trough that is east of Hawaii.  The upper level winds are weak near the middle of the trough and there will be little vertical wind shear.  Tropical Storm Henriette will intensify during the next 24 hours.

Tropical Storm Henriette will move around the southwestern part of a high pressure system over the Eastern North Pacific Ocean.  The high pressure system will steer Henriette toward the northwest during the next 24 hours.  On its anticipated track, Tropical Storm Henriette will pass well to the north of Hawaii.

Elsewhere, Tropical Storm Ivo was weakening southwest of Baja California.  At 5:00 a.m. EDT on Sunday the center of Tropical Storm Ivo was located at latitude 21.5°N and longitude 114.9°W which put the center about 335 miles (535 km) west-southwest of the southern tip of Baja California.  Ivo was moving toward the west-northwest at 8 m.p.h. (13 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 1006 mb.

Tropical Storm Ivo Moves South of Baja California

Tropical Storm Ivo moved south of Baja California on Friday.  At 5:00 p.m. EDT on Friday the center of Tropical Storm Ivo was located at latitude 20.4°N and longitude 111.2°W which put the center about 190 miles (310 km) south-southwest of the southern tip of Baja California.  Ivo was moving toward the west at 13 m.p.h. (21 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 999 mb.

Tropical Storm Ivo exhibited much more organization on Friday after it moved south of Baja California.  The inner end of a rainband wrapped around the western side of the center of Ivo’s circulation.  Other bands of showers and thunderstorms were revolving around the center of Tropical Storm Ivo.  Storms near the center of Ivo generated upper level divergence that pumped mass away from the tropical storm.  The removal of mass caused the surface pressure to decrease.

The circulation around Tropical Storm Ivo was small.  Winds to tropical storm force extended out 35 miles (55 km) from the center of Ivo’s circulation.

Tropical Storm Ivo will move through an environment mostly favorable for intensification during the next 24 hours.  Ivo will move over water where the Sea Surface Temperatures are near 27°C.  It will move under the southern side of an upper level ridge over Mexico and the Eastern North Pacific Ocean.  The upper level ridge will produce easterly winds that will blow toward the top of Ivo’s circulation.  However, the winds in the lower atmosphere will also blow from the east.  Since the winds in the upper and lower levels of the atmosphere will blow from the same direction, there will be less vertical wind shear.  Tropical Storm Ivo is likely to intensify during the next 24 hours.  Ivo could strengthen to a hurricane on Saturday.  Ivo will move over cooler water on Sunday which will cause it to weaken.

Tropical Storm Ivo will move around the southern side of a high pressure system that is over Mexico and the eastern North Pacific Ocean.  The high pressure system will steer Ivo toward the west during the next 24 hours.  On its anticipated track, Tropical Storm Ivo will move away from Baja California during the weekend.

Tropical Storm Ivo Moves Southeast of Baja California

Tropical Storm Ivo moved southeast of Baja California on Thursday evening.  At 5:00 p.m. EDT on Thursday the center of Tropical Storm Ivo was located at latitude 19.7°N and longitude 107.3°W which put the center about 275 miles (445 km) southeast of the southern tip of Baja California.  Ivo was moving toward the northwest at 22 m.p.h. (35 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 1001 mb.

Even though Tropical Storm Ivo strengthened on Thursday, its structure did not change a lot.  Thunderstorms were still forming near the center of Ivo’s circulation.  Thunderstorms were also occurring in bands in the southern and eastern parts of Tropical Storm Ivo.  Bands in the northern and western parts of Ivo’s circulation consisted primarily of showers and lower clouds.

The circulation around Tropical Storm Ivo was small.  Winds to tropical storm force extended out 45 miles (75 km) from the center of Ivo’s circulation.

Tropical Storm Ivo will move through an environment mostly favorable for intensification during the next 24 hours.  Ivo will move over water where the Sea Surface Temperatures are near 29°C.  It will move under the southern side of an upper level ridge over Mexico.  The upper level ridge will produce easterly winds that will blow toward the top of Ivo’s circulation.  However, the winds in the lower atmosphere will also blow from the east.  Since the winds in the upper and lower levels of the atmosphere will blow from the same direction, there will be less vertical wind shear.  Even though Tropical Storm Ivo will move through an environment most favorable for intensification, Ivo may not intensify a lot on Friday as long as it continues to move quickly toward the west-northwest.  If Tropical Storm Ivo starts to move more slowly, then it could intensify again.

Tropical Storm Ivo will move around the southern side of a high pressure system that is over Mexico.  The high pressure system will steer Ivo toward the west-northwest during the next 24 hours.  On its anticipated track, Tropical Storm Ivo will move south of Baja California on Friday.

Elsewhere over the Eastern North Pacific Ocean, Tropical Storm Henriette weakened slowly as it approached the Central Pacific.  At 5:00 p.m. EDT on Thursday the center of Tropical Storm Henriette was located at latitude 19.1°N and longitude 138.4°W which put the center about 1090 miles (1750 km) east Hilo, Hawaii.  Henriette was moving toward the west at 16 m.p.h. (26 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 1007 mb.

Tropical Storm Henriette Churns Westward

Tropical Storm Henriette churned westward over the Eastern North Pacific Ocean on Tuesday.  At 5:00 p.m. EDT on Tuesday the center of Tropical Storm Henriette was located at latitude 17.0°N and longitude 125.6°W which put the center about 1095 miles (1765 km) west-southwest of the southern tip of Baja California.  Henriette was moving toward the west-northwest at 16 m.p.h. (26 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 1003 mb.

The structure of Tropical Storm Henriette did not change much on Tuesday.  The distribution of thunderstorms in Tropical Storm Henriette continued to be asymmetrical.  Thunderstorms were occurring in bands in the western side of Henriette’s circulation.  Bands in the eastern side of Tropical Storm Henriette consisted primarily of showers and lower clouds.  Storms on the western side of the center of Henriette generated upper level divergence that pumped mass away to the west of the tropical storm.  The removal of mass in the upper levels was balanced by an inflow of mass in the lower levels of the atmosphere.  The balance of outflow and inflow of mass caused the surface pressure to remain nearly constant.

The size of the circulation around Tropical Storm Henriette increased a little on Tuesday.  Winds to tropical storm force extended out 70 miles (110 km) from the center of Henriette’s circulation.

Tropical Storm Henriette will move through an environment marginally favorable for intensification during the next 24 hours.  Henriette will move over water where the Sea Surface Temperatures are near 26°C.  It will move under the southern side of an upper level ridge over the Eastern North Pacific Ocean.  The upper level ridge will produce easterly winds that will blow toward the top of Henriette’s circulation.  Those winds will cause some vertical wind shear. The vertical wind shear will inhibit intensification.  The intensity of Tropical Storm Henriette is likely to remain nearly constant during the next 24 hours.

Tropical Storm Henriette will move around the southern side of a high pressure system over the Eastern North Pacific Ocean.  The high pressure system will steer Henriette toward the west-northwest during the next 24 hours.  On its anticipated track, Tropical Storm Henriette will continue to move farther away from Baja California.

Tropical Storm Henriette Forms Southwest of Baja California

Tropical Storm Henriette formed over the Eastern North Pacific Ocean southwest of Baja California on Monday afternoon.  At 5:00 p.m. EDT on Monday the center of Tropical Storm Henriette was located at latitude 14.8°N and longitude 120.6°W which put the center about 895 miles (1440 km) southwest of the southern tip of Baja California.  Henriette was moving toward the west-northwest at 15 m.p.h. (24 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 1004 mb.

A low pressure system over the Eastern North Pacific Ocean southwest of Baja California strengthened on Monday afternoon and the U.S. National Hurricane Center designated the system as Tropical Storm Henriette.

Gil Strengthens to a Hurricane

Former Tropical Storm Gil strengthened to a hurricane over the Eastern North Pacific Ocean southwest of Baja California on Friday.  At 11:00 p.m. EDT on Friday the center of Hurricane Gil was located at latitude 16.5°N and longitude 125.1°W which put the center about 1080 miles (1740 km) west-southwest of the southern tip of Baja California.  Gil was moving toward the west-northwest at 20 m.p.h. (32 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 991 mb.

Former Tropical Storm Gil strengthened to a hurricane on Friday.  The inner end of a rainband wrapped around the western and southern sides of the center of Gil’s circulation.  Bands of showers and thunderstorms were revolving around the center of Hurricane Gil.  Storms near the center of Gil generated upper level divergence that pumped mass away from the hurricane.  The removal of mass caused the surface pressure to decrease.

The strongest winds were occurring in the northeastern part of Hurricane Gil.  Winds to hurricane force extended out 25 miles (40 km) in the northeastern quadrant of Gil’s circulation.  Winds to tropical storm force extended out 125 miles (200 km) from the center of Hurricane Gil.

Hurricane Gil will move through an environment somewhat favorable for intensification during the next 24 hours.  Gil will move over water where the Sea Surface Temperatures are near 27°C.  It will move through a region where there will be little vertical wind shear.  However, Gil will move into a region where there is very dry air.  The dry air will inhibit intensification.  Hurricane Gil could intensify during the next 24 hours if the dry air does not penetrate to the core of Gil’s circulation.

Hurricane Gil will move around the southern side of a high pressure system over the Eastern North Pacific Ocean.  The high pressure system will steer Gil toward the west-northwest during the next 24 hours.  On its anticipated track, Hurricane Gil will continue to move farther away from Baja California.

Elsewhere, former Tropical Storm Iona weakened to a tropical depression as it approached the International Date Line.  At 11:00 p.m. EDT on Friday the center of Tropical Depression Iona was located at latitude 15.8°N and longitude 179.5°W which put the center about 1465 miles (2355 km) west of Honolulu, Hawaii.  Iona was moving toward the west-northwest at 17 m.p.h. (28 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 1008 mb.
