Tropical Storm John Redevelops West of Acapulco

Tropical Storm John redeveloped over the Eastern North Pacific Ocean west of Acapulco on Wednesday.  At 2:00 p.m. EDT on Wednesday the center of Tropical Storm John was located at latitude 16.5°N and longitude 101.4°W which put the center about 105 miles (165 km) west-southwest of Acapulco, Mexico.  John was moving toward the north-northeast at 3 m.p.h. (5 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 999 mb.

A Hurricane Watch is in effect for the portion of the coast from Zihuatanejo to Acapulco, Mexico.

A Tropical Storm Warning is in effect for the portion of the coast from Punta Maldonado to Lazaro Cardenas, Mexico.  The Tropical Storm Warning includes Acapulco.

The middle level circulation of former Hurricane John drifted west-southwest during the past 36 hours.  When the middle level circulation moved back over the Eastern North Pacific Ocean, it began to spin up a surface low pressure system.  The surface low pressure system intensified on Wednesday and the U.S. National Hurricane Center designated it as Tropical Storm John.

The circulation around Tropical Storm John organized rapidly on Wednesday.  The inner end of a rainband wrapped around the eastern, northern and western sides of the center of John’s circulation.  Other bands of showers and thunderstorms were revolving around the center of Tropical Storm John.  Storms near the center generated upper level divergence that pumped mass away from the tropical storm.

The strongest winds were occurring in the eastern side of Tropical Storm John.  Winds to tropical storm force extended out 80 miles (130 km) in the eastern side of John’s circulation.  The winds in the western side of Tropical Storm John were blowing at less than tropical storm force.

Tropical Storm John will move through an environment favorable for intensification during the next 24 hours.  John will move over water where the Sea Surface Temperatures are near 30°C.  It will be in a region where the upper level winds are weak and there will be little vertical wind shear.  Tropical Storm John will intensify during the next 24 hours.  John could strengthen back to a hurricane.

Tropical Storm John will move around the southwestern part of a high pressure system over Mexico.  The high pressure system will steer John slowly toward the north during the next 24 hours.  On its anticipated track, Tropical Storm John will make another landfall on the coast of Mexico on Thursday.  The center of John’s circulation is likely to make landfall between Acapulco and Zihuatanejo.

Tropical Storm John  could be a hurricane when it makes landfall.  John will bring strong winds and locally heavy rain to the coast of Mexico between Acapulco and Zihuatanejo.  Heavy rain will also fall over Guerrero as John moves inland again.  Heavy rain is likely to cause flash floods in some locations.  Tropical Storm John could cause a storm surge of up to 7 feet (2 meters) along parts of the coast of Guerrero.

Tropical Storm Pilar Speeds Westward

Tropical Storm Pilar sped westward over the Eastern North Pacific Ocean south of Mexico on Friday. At 5:00 p.m. EDT on Friday the center of Tropical Storm Pilar was located at latitude 10.1°N and longitude 104.0°W which put it about 560 miles (905 km) south-southwest of Zihuatanejo, Mexico. Pilar was moving toward the west at 20 m.p.h. (32 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 1002 mb.

Tropical Storm Pilar weakened on Friday as it sped westward over the Eastern North Pacific Ocean. Thunderstorms were occurring in a couple of bands west and south of the center of Pilar’s circulation. Bands in the eastern and northern parts of Tropical Storm Pilar consisted primarily of showers and lower clouds. Winds to tropical storm force extended out 80 miles (130 km) in the northern side of Pilar’s circulation. The winds in the southern half of the circulation were blowing at less than tropical storm force.

Tropical Storm Pilar will move through an environment that will be unfavorable for intensification during the next 24 hours. Pilar will move over water where the Sea Surface Temperatures are near 29°C. It will move under the southern part of a narrow, west to east upper level ridge over the Eastern North Pacific Ocean. The upper level ridge will produce easterly winds that will blow toward the top of Pilar’s circulation. Those winds will cause moderate vertical wind shear. The moderate vertical wind shear could cause Tropical Storm Pilar to weaken a little more on Saturday.

Tropical Storm Pilar will move around the southern part of a high pressure system over the Eastern North Pacific Ocean. The high pressure system will steer Pilar toward the west during the next 24 hours. On its anticipated track, Tropical Storm Pilar will continue to move farther away from Mexico on Saturday.

Hurricane Otis continued to intensify rapidly on Tuesday evening. A circular eye with a diameter of 17 miles (28 km) was at the center of Hurricane Otis. 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 Hurricane Otis. Storms near the core of Otis generated strong upper level divergence that pumped large quantities of mass away from the hurricane in all directions. The removal of large amounts of mass caused the surface pressure to decrease rapidly.

Winds to hurricane force extended out 30 miles (50 km) from the center of Hurricane Otis. Winds to tropical storm force extended out 70 miles (110 km) from the center of circulation. The Hurricane Intensity Index (HII) was 35.0. The Hurricane Size Index (HSI) was 9.3 and the Hurricane Wind Intensity Size Index (HWISI) was 44.3. Hurricane Otis was similar in intensity to Hurricane Michael when Michael hit Northwest Florida in 2018. Otis was a little smaller than Michael was.

Hurricane Otis will move around the southwestern part of a high pressure system over the Gulf of Mexico. The high pressure system will steer Otis toward the north-northwest during the next 24 hours. On its anticipated track, the center of Hurricane Otis will make landfall near Acapulco in a few hours.

Hurricane Otis will move through an environment favorable for intensification until it makes landfall on the coast of Mexico. Otis will move over water where the Sea Surface Temperatures are near 29°C. An upper level ridge over Gulf of Mexico will produce southeasterly winds that will blow toward the top of Otis’ circulation. The winds in the lower levels of the atmosphere will also blow from the southeast and there will be little vertical wind shear. Hurricane Otis could intensify more before it makes landfall.

Hurricane Otis could be a Category 5 hurricane when it makes landfall near Acapulco. Otis will be capable of causing catastrophic damage. Hurricane Otis will bring extremely strong winds to Acapulco. Widespread outages of electricity are likely. Otis will also drop heavy rain on Guerrero. Heavy rain is likely to cause flash floods in some locations. Otis could produce a storm surge of up to 15 feet (4.5 meters) along the coast.
