Tropical Storm Hilary Forms South of Mexico

Tropical Storm Hilary formed over the Eastern North Pacific Ocean south of Mexico on Wednesday morning. At 11:00 a.m. EDT on Wednesday the center of Tropical Storm Hilary was located at latitude 12.4°N and longitude 102.6°W which put it about 470 miles (755 km) south-southeast of Manzanillo, Mexico. Hilary was moving toward the west-northwest 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 1002 mb.

A low pressure system over the Eastern North Pacific Ocean south of Mexico strengthened on Wednesday morning and the U.S. National Hurricane Center designated the system as Tropical Storm Hilary. The circulation around Tropical Storm Hilary was organizing quickly. Multiple bands of showers and thunderstorms were revolving around the center of Hilary’s circulation. Storms near the center generated upper level divergence that pumped mass away from the tropical storm. Winds to tropical storm force extended out 200 miles (325 km) in the northeastern quadrant of Tropical Storm Hilary. Winds in the other parts of Hilary’s circulation were blowing at less than tropical storm force.

Tropical Storm Hilary will move through an environment very favorable for intensification during the next 24 hours. Hilary will move over water where the Sea Surface Temperatures are near 30°C. It will move through a region where the upper level winds are weak and there will be little vertical wind shear. Tropical Storm Hilary will intensify during the next 24 hours. Hilary could intensify rapidly at times. Tropical Storm Hilary is likely to strengthen to a hurricane on Thursday.

Tropical Storm Hilary will move around the western part of a high pressure system over Mexico. The high pressure system will steer Hilary toward the west-northwest during the next 24 hours. On its anticipated track Tropical Storm Hilary will move parallel to the west coast of Mexico. Hilary will move more toward the north when it reaches the western end of the high pressure system during the weekend. Hilary could be near Baja California by Sunday.

Hurricane Fernanda will move through an environment favorable for intensification during the next 12 hours. Fernanda will move over water where the Sea Surface Temperatures are near 29°C. It will move through a region where the upper level winds are weak and there will be little vertical wind shear. Hurricane Fernanda is likely to continue to intensify during the next 12 hours. Fernanda will move over slightly cooler water on Tuesday. The cooler water will cause Fernanda to start to weaken.

Hurricane Fernanda will move south of a subtropical high pressure system over the Eastern North Pacific Ocean. The high pressure system will steer Fernanda toward the west during the next 24 hours. On its anticipated track, Hurricane Fernanda will move farther away from Baja California.

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.

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.
