Hurricane Dora Moves Southeast of Hawaii

Hurricane Dora moved southeast of Hawaii on Monday. At 11:00 p.m. EDT on Monday the center of Hurricane Dora was located at latitude 12.0°N and longitude 152.3°W which put it about 565 miles (905 km) south-southeast of Hilo, Hawaii. Dora was moving toward the west at 23 m.p.h. (37 km/h). The maximum sustained wind speed was 130 m.p.h. (210 km/h) and there were wind gusts to 155 m.p.h. (250 km/h). The minimum surface pressure was 953 mb.

Hurricane Dora weakened slightly on Monday. The structure of Dora continued to be very symmetrical. An eye with a diameter of 12 miles (19 km) was at the center of Hurricane Dora. 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 Dora’s circulation. Storms near the core generated upper level divergence that pumped mass away from the hurricane.

The size of the circulation around Hurricane Dora increased a little on Monday. Winds to hurricane force extended out 30 miles (50 km) from the center of Dora’s circulation. Winds to tropical storm force extended out 115 miles (185 km) from the center of circulation. The Hurricane Intensity Index (HII) was 25.1. The Hurricane Size Index (HSI) was 9.9 and the Hurricane Wind Intensity Size Index (HWISI) was 35.0.

Hurricane Dora will move through an environment that will be favorable for a major hurricane during the next 24 hours. Dora will move over water where the Sea Surface Temperatures are near 26.5°C. It will move through a region where the upper level winds are weak and there will be little vertical wind shear. Hurricane Dora could move into a region where the air is a little drier. Since the circulation around Hurricane Dora is so small, any changes in the environment will have large effects on the intensity of Dora. Hurricane Dora could weaken a little more during the next 24 hours because of the drier air.

Hurricane Dora will move south of a subtropical high pressure system over the North Pacific Ocean. The high pressure system will steer Dora toward the west during the next 24 hours. On its anticipated track, Hurricane Dora will pass south of Hawaii on Tuesday.

Elsewhere, former Tropical Storm Eugene weakened west of Baja California on Monday. At 5:00 p.m. EDT on Monday the center of Tropical Depression Eugene was located at latitude 25.1°N and longitude 120.4°W which put it about 680 miles (1095 km) west-northwest of the southern tip of Baja California. Eugene was moving toward the west-northwest at 14 m.p.h. (22 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.

Hurricane Dora Moves over the Central Pacific

Hurricane Dora moved over the Central Pacific Ocean on Sunday. At 11:00 p.m. EDT on Sunday the center of Hurricane Dora was located at latitude 12.7°N and longitude 144.0°W which put it about 890 miles (1430 km) east-southeast of the South Point, Hawaii. Dora was moving toward the west at 22 m.p.h. (35 km/h). The maximum sustained wind speed was 140 m.p.h. (225 km/h) and there were wind gusts to 165 m.p.h. (270 km/h). The minimum surface pressure was 950 mb.

Hurricane Dora did not change much on Sunday. The structure of Dora continued to be very symmetrical and it had a a shape sometimes called an annular hurricane. An eye with a diameter of 17 miles (28 km) was at the center of Hurricane Dora. The eye was surrounded by a ring of thunderstorms and the strongest winds were occurring in that ring of storms. Short bands of showers and thunderstorms were revolving around the core of Dora’s circulation. Storms near the core generated upper level divergence that pumped mass away from the hurricane.

The circulation around Hurricane Dora was still very small. Winds to hurricane force extended out 25 miles (40 km) from the center of Dora’s circulation. Winds to tropical storm force extended out 70 miles (110 km) from the center of circulation. The Hurricane Intensity Index (HII) was 28.3. The Hurricane Size Index (HSI) was only 7.0 and the Hurricane Wind Intensity Size Index (HWISI) was 35.36. Hurricane Dora was similar in size and intensity to Hurricane Charley when Charley hit southwest Florida in 2004.

Hurricane Dora will move through an environment that will be favorable for a powerful hurricane during the next 24 hours. Dora will move over water where the Sea Surface Temperatures are near 26.5C. It will move through a region where the upper level winds are weak and there will be little vertical wind shear. Hurricane Dora could move into a region where the air is a little drier. The intensity of an annual hurricane usually remains relatively constant. However, since the circulation around Hurricane Dora is so small, any changes in the environment will have large effects on the intensity of Dora. Hurricane Dora could weaken a little during the next 24 hours, if it moves into a region where the air is a little drier.

Hurricane Dora will move south of a subtropical high pressure system over the Eastern North Pacific Ocean. The high pressure system will steer Dora toward the west during the next 24 hours. On its anticipated track, Hurricane Dora will pass south of Hawaii on Tuesday.

The minimum surface pressure was 956 mb.

Hurricane Dora continued to intensify rapidly on Wednesday and Dora reached major hurricane intensity on Wednesday evening. A small eye with a diameter of 12 miles (19 km) was at the center of Dora’s circulation. The eye was surrounded by a ring of strong thunderstorms and the strongest winds were occurring in that ring of storms. Bands of showers and thunderstorms were revolving around the core of Hurricane Dora. Storms near the core generated upper level divergence that pumped mass away from the hurricane in all directions.

The circulation around Hurricane Dora was very small. Winds to hurricane force extended out 20 miles (30 km) from the center of Dora’s circulation. Winds to tropical storm force extended out 45 miles (75 km) from the center of circulation. The Hurricane Intensity Index (HII) was 23.6. The Hurricane Size Index (HSI) was only 5.6 and the Hurricane Wind Intensity Size Index (HWISI) was 29.2. Most of Hurricane Dora’s circulation would fit inside the outer eyewall of Typhoon Khanun.

Hurricane Dora will move through an environment favorable for intensification during the next 24 hours. Dora will move over water where the Sea Surface Temperatures are near 28˚C. It through a region where the upper level winds are weak and there will be little vertical wind shear. Hurricane Dora is likely to continue to intensify during the next 24 hours. Dora could continue to intensify rapidly during the next 12 hours. Since the circulation around Hurricane Dora is so small, any changes in the environment will have large effects on the intensity of Hurricane Dora.

Hurricane Dora will move south of a subtropical high pressure system over the Eastern North Pacific Ocean. The high pressure system will steer Dora toward the west-southwest during the next 24 hours. On its anticipated track, Hurricane Dora will move farther away from Mexico. Dora could be southeast of Hawaii by the early next week.

Calvin Intensifies to a Hurricane

Former Tropical Storm Calvin intensified to a hurricane on Thursday morning. At 11:00 a.m. EDT on Thursday the center of Hurricane Calvin was located at latitude 12.7°N and longitude 117.1°W which put it about 850 miles (1365 km) southwest of the southern tip of Baja California. Calvin was moving toward the west at 13 m.p.h. (20 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 993 mb.

Former Tropical Storm Calvin intensified rapidly to a hurricane during the past 30 hours. The inner end of rainband wrapped around the center of Hurricane Calvin’s circulation. An eye was beginning to appear at the center of circulation on satellite images. The eye was surrounded by a broken ring of thunderstorms. The strongest winds were occurring in the northeastern part of the ring of storms. Bands of showers and thunderstorms were revolving around the core of Hurricane Calvin. Storms near the core generated upper level divergence that pumped mass away from the hurricane.

The circulation around Hurricane Calvin was small. Winds to hurricane force extended out 25 miles (40 km) in the northeastern quadrant of Calvin’s circulation. Winds to tropical storm force extended out 70 miles (110 km) from the center of Hurricane Calvin.

Hurricane Calvin will move through an environment that will be favorable for intensification during the next 24 hours. Calvin will move over water where the Sea Surface Temperatures are near 28˚C. It will move through a region where then upper level winds that are weak and there will be little vertical wind shear. Hurricane Calvin will intensify during the next 24 hours. Calvin could intensify rapidly at times once the inner core is more fully formed.

Hurricane Calvin will move around the southern part of a subtropical high pressure system over the Eastern North Pacific Ocean. The high pressure system will steer Calvin toward the west during the next several days. On its anticipated track, Hurricane Calvin will move toward the Central Pacific Ocean. Calvin is likely to weaken when it moves over cooler water in the Central Pacific, but it could be east of Hawaii by early next week.

Tropical Storm Calvin Forms South of Baja California

Tropical Storm Calvin formed over the Eastern North Pacific Ocean south of Baja California on Wednesday morning. At 5:00 a.m. EDT on Wednesday the center of Tropical Storm Calvin was located at latitude 10.4°N and longitude 110.6°W which put it about 725 miles (1170 km) south of the southern tip of Baja California. Calvin was moving toward the west at 16 m.p.h. (26 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. (105 km/h). The minimum surface pressure was 1004 mb.

A low pressure system over the Eastern North Pacific Ocean south of Baja California strengthened on Wednesday morning and the U.S. National Hurricane Center designated the system as Tropical Storm Calvin. The distribution of thunderstorms in Tropical Storm Calvin was asymmetrical. Most thunderstorms were occurring in bands in the western side of Calvin’s circulation. Bands in the eastern side of Calvin consisted primarily of showers and lower clouds. The inner end of a rainband wrapped around the southern side of the center of Tropical Storm Calvin. Storms near the center generated upper level divergence that pumped mass away from the tropical storm. The circulation around Calvin was small. Winds to tropical storm force extended out 45 miles (75 km) from the center of Calvin’s circulation.

Tropical Storm Calvin will move through an environment that will be mostly favorable for intensification during the next 36 hours. Calvin 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 over Mexico and the southwestern U.S. The upper level ridge will produce easterly winds that will blow toward the top of Calvin’s circulation. Those winds will cause vertical wind shear. The wind shear will inhibit intensification, but the shear will not be enough to prevent Calvin from getting stronger. Tropical Storm Calvin will intensify during the next 36 hours. Calvin could strengthen to a hurricane by Friday.

Tropical Storm Calvin will move around the southern part of a subtropical high pressure system over the Eastern North Pacific Ocean. The high pressure system will Calvin toward the west during the next few days. On its anticipated track, Tropical Storm Calvin will move farther away from Mexico. Calvin could move over the Central Pacific Ocean early next week.

Tropical Storm Beatriz Moves Along West Coast of Mexico

Tropical Storm Beatriz was moving along the west coast of Mexico on Saturday morning. At 8:00 a.m. EDT on Saturday the center of Tropical Storm Beatriz was located at latitude 19.8°N and longitude 105.4°W which put it about 45 miles (75 km) south-southeast of Cabo Corrientes, Mexico. Beatriz was moving toward the northwest at 13 m.p.h. (20 km/h). The maximum sustained wind speed was 60 m.p.h. (75 km/h) and there were wind gusts to 75 m.p.h. (120 km/h). The minimum surface pressure was 1001 mb.

Tropical Storm Warnings were in effect for the portions of the coast from Manzanillo to Punta Mita, Mexico. A Tropical Storm Watch was in effect for the portion of the coast from Punta Mita to San Blas, Mexico. A Tropical Storm Watch was also in effect for Las Islas Marias.

The center of former Hurricane Beatriz made a landfall near Punta San Telmo, Mexico during Friday night. When the center of Beatriz made landfall, it significantly disrupted the inner core of Beatriz’ circulation. The disruption of the inner core caused Beatriz to weaken to a tropical storm. The distribution of thunderstorms in Tropical Storm Beatriz became asymmetrical after if made landfall. Most of the thunderstorms were occurring in bands in the western half of Beatriz’ circulation. Bands in the eastern part of the tropical storm consisted primarily of showers and lower clouds. Winds to tropical storm force extended out 80 miles (130 km) from the center of Tropical Storm Beatriz.

Former Hurricane Beatriz brought gusty winds and locally heavy rain to the west coast of Mexico from Punta San Telmo to Cabo Corrientes during Friday night. The heaviest rain fell along the coast in Michoacan, Colima and Jalisco.

Tropical Storm Beatriz will move through an environment that will be only marginally favorable for intensification during the next 36 hours. Beatriz 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 over northern Mexico. The upper level ridge will produce easterly winds that will blow toward the top of Beatriz’ circulation. Those winds will cause the wind shear to increase. Since Tropical Storm Beatriz is near the west coast of Mexico, it’s circulation will pull drier air into the eastern and northern parts of Beatriz. The drier air will inhibit the formation of thunderstorms in those parts of the circulation. Since the inner core of Tropical Storm Beatriz was disrupted when it moved over the coast, Beatriz is likely to continue to weaken during the next 36 hours.

The upper level ridge over northern Mexico will steer Tropical Storm Beatriz toward the northwest during the next 36 hours. On its anticipated track, Tropical Storm Beatriz will gradually move away from the west coast of Mexico. The gusty winds and locally heavy rain in Jalisco will gradually diminish on Saturday. Beatriz could move southeast of Baja California on Sunday.

Elsewhere over the Eastern North Pacific Ocean, Hurricane Adrian weakened south of Baja California. At 5:00 a.m. EDT on Saturday the center of Hurricane Adrian was located at latitude 18.1°N and longitude 114.0°W which put it about 425 miles (685 km) southwest of the southern tip of Baja California. Adrian was moving toward the west-northwest at 7 m.p.h. (11 km/h). The maximum sustained wind speed was 80 m.p.h. (130 km/h) and there were wind gusts to 95 m.p.h. (150 km/h). The minimum surface pressure was 983 mb.
