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.

 

Tropical Storm Akoni Develops Southeast of Hawaii

Tropical Storm Akoni developed southeast of Hawaii on Thursday.  At 7:00 p.m. EDT on Thursday the center of Tropical Storm Akoni was located at latitude 12.2°N and longitude 144.8°W which put it about 855 miles (1380 km) southeast of Hilo, Hawaii.  Akoni was moving toward the west at 7 m.p.h. (11 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 1003 mb.

More thunderstorms developed near an area of low pressure southeast of Hawaii on Thursday and the Central Pacific Hurricane Center designated it as Tropical Storm Akoni when satellites indicated there were winds to tropical storm force.  The circulation around Tropical Storm Akoni was still organizing.  Bands of showers and thunderstorms were forming.  The strongest rainbands were in the southern half of the circulation.  Bands in the northern half of the circulation were not as strong.  Winds to tropical storm force extended out about 70 miles (110 km) from the center of circulation.

Tropical Storm Akoni will move through an environment favorable for intensification during the next several days.  Akoni will move over water where the Sea Surface Temperature is near 28°C.  It will move southeast of an upper level trough northeast of Hawaii.  The trough will produce southwesterly winds which will cause some vertical wind shear, but the shear will not be strong enough to prevent intensification.  Tropical Storm Akoni is forecast to strengthen gradually during the next several days.

Tropical Storm Akoni will move south of a subtropical high pressure system over the eastern and central Pacific Ocean.  The high will steer Akoni toward the west-northwest.  On its anticipated track Tropical Storm Akoni will be south of Hawaii on Sunday.

Elsewhere, Hurricane Juliette was weakening slowly southwest of Baja California.  At 5:00 p.m. EDT on Thursday the center of Hurricane Juliette was located at latitude 21.3°N and 120.8°W which put it about 870 miles (1380 km) west-southwest of the southern tip of Baja California.  Juliette was moving toward the northwest at 12 m.p.h. (19 km/h).  The maximum sustained wind speed was 85 m.p.h. (135 km/h) and there were wind gusts to 100 m.p.h. (160 km/h).  The minimum surface pressure was 980 mb.

Juliette Rapidly Intensifies Into a Major Hurricane

Hurricane Juliette rapidly intensified into a major hurricane southwest of Baja California on Monday. At 11:00 p.m. EDT on Monday the center of Hurricane Juliette was located at latitude 17.8°N and longitude 114.0°W which put it abou 440 miles (710 km) southwest of the southern tip of Baja California.  Juliette was moving toward the northwest 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 140 m.p.h. (220 km/h).  The minimum surface pressure was 963 mb.

Hurricane Juliette intensified rapidly on Monday as it moved through an environment of warm water and littler vertical wind shear.  An eye developed at the center of circulation.  The eye was surrounded by a ring of strong thunderstorms and the strongest winds were occurring in that ring of storms.  Bands of strong thunderstorms increased in the eastern half of the circulation.  Bands in the western half of the circulation contained fewer thunderstorms.  Storms around the core of Juliette generated strong upper level divergence which pumped mass away from the hurricane.  Winds to hurricane force extended out about 20 miles (30 km) from the center of circulation.  Winds to tropical storm force extended out about 125 miles (200 km) from the center.

Hurricane Juliette will remain in an environment favorable for intensification for another day or so.  Juliette will move over water where the Sea Surface Temperature is near 28°C.  It will move through a region where the upper level winds are not too strong and there will be little vertical wind shear.  Hurricane Juliette could strengthen further on Tuesday.  Juliette will move over cooler water later this week and it will start to weaken.

Hurricane Juliette will move southwest of a ridge over the southwestern U.S.  The ridge will steer Juliette toward the northwest.  On its anticipated track Hurricane Juliette will remain well west of Baja California.

Tropical Storm Juliette Develops Rapidly South of Baja California

Tropical Storm Juliette developed rapidly south of Baja California on Sunday.  At 11:00 a.m. EDT on Sunday the center of Tropical Storm Juliette was located at latitude 14.3°N and longitude 108.8°W which put it about 600 miles (965 km) south of the southern tip of Baja California.  Juliette was moving toward the northwest at 14 m.p.h. (22 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 1000 mb.

The circulation around Tropical Storm Juliette organized very rapidly on Sunday.  The inner end of a rainband wrapped around the center of circulation and a circular eye appeared to be forming at the center of Juliette.  Other bands of showers and thunderstorms were revolving around the core of the circulation.  Storms near the core were generating upper level divergence which was pumping mass away from the tropical storm.  Winds to tropical storm force extended out about 80 miles (130 km) from the center of circulation.

Tropical Storm Juliette will move through an environment very favorable for intensification.  Juliette will move over water where the Sea Surface Temperature is near 29°C.  It will move through a region where the upper level winds are weak and there will is little vertical wind shear.  Tropical Storm Juliette is likely to continue to intensify rapidly during the next day or two.  Juliette is likely to strengthen into a hurricane within 12 hours and it could be a major hurricane within 48 hours.
