Flossie Intensifies to a Major Hurricane

Hurricane Flossie intensified to a major hurricane over the Eastern North Pacific Ocean southwest of Mexico on Tuesday evening.  At 11:00 p.m. EDT on Tuesday the center of Hurricane Flossie was located at latitude 18.2°N and longitude 107.4°W which put the center about 365 miles (585 km) south-southeast of Cabo San Lucas, Mexico.   Flossie was moving toward the west-northwest at 9 m.p.h. (15 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 962 mb.

A Tropical Storm Warning is in effect for the portion of the coast from Punta San Telmo to Playa Perula, Mexico.

Hurricane Flossie continued to intensify on Tuesday evening.  A circular eye was at the center of Flossie’s circulation.  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 Flossie.  Storms near the center of Flossie generated upper level divergence that pumped mass away from the hurricane in all directions.  The removal of mass caused the surface pressure to decrease.

The circulation around Hurricane Flossie was relatively small.  Winds to hurricane force extended out 25 miles (40 km) from the center of Flossie’s circulation.  Winds to tropical storm force extended out 90 miles (145 km) from the center of Hurricane Flossie.

The Hurricane Intensity Index (HII) for Hurricane Flossie is 20.6.  The Hurricane Size Index (HSI) is 8.3 and the Hurricane Wind Intensity Size Index (HWISI) is 28.9.  Hurricane Flossie is similar in size and intensity to Hurricane Zeta when Zeta hit Louisiana in 2020.

Hurricane Flossie will move through an environment that will be somewhat favorable for intensification during the next 12 hours.  Flossie will move over water where where the Sea Surface Temperatures are near 27°C.  It will move under the middle of an upper level ridge over Mexico and the adjacent part of the Eastern North Pacific Ocean.  The upper level winds are weak near the middle of the ridge and there will be little vertical wind shear.  Hurricane Flossie could continue to intensify during the next 12 hours.  Flossie will move over cooler water later in Wednesday.  Hurricane Flossie will start to weaken when it moves over cooler water.

Hurricane Flossie will move around the southwestern part of a high pressure system over Mexico.  The high pressure system will steer the Flossie toward the northwest during the next 24 hours.  On its anticipated track, Hurricane Flossie will start to move farther away from the coast of southwestern Mexico.  Flossie will move south of Baja California on Wednesday night.

Bands in the northeastern side of Hurricane Flossie will bring gusty winds and locally heavy rain to parts of the coast of southwestern Mexico.  The heaviest rain will fall in parts of Michoacan, Colima, and Jalisco.  Heavy rain could cause flash floods in some locations.

Hurricane Flossie Strengthens to Cat. 2

Hurricane Flossie strengthened to Category 2 on the Saffir-Simpson Scale as it moved over the Eastern North Pacific Ocean southwest of Mexico on Tuesday morning.  At 11:00 a.m. EDT on Tuesday the center of Hurricane Flossie was located at latitude 17.4°N and longitude 105.9°W which put the center about 150 miles (240 km) southwest of Manzanillo, Mexico.  Flossie was moving toward the northwest at 10 m.p.h. (16 km/h).  The maximum sustained wind speed was 100 m.p.h. (160 km/h) and there were wind gusts to 120 m.p.h. (195 km/h).  The minimum surface pressure was 974 mb.

A Tropical Storm Warning is in effect for the portion of the coast from Punta San Telmo to Playa Perula, Mexico.

A Tropical Storm Watch is in effect for the portion of the coast from Playa Perula to Cabo Corrientes, Mexico.  A Tropical Storm Watch is in effect for the portion of the coast from Punta San Telmo to Zihuatanejo, Mexico.

The inner end of a rainband wrapped around the center of Hurricane Flossie on Tuesday morning.  A circular eye was visible at the center of Flossie’s circulation on satellite images.  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 Flossie.  Storms near the center of Flossie generated upper level divergence that pumped mass away from the hurricane in all directions.  The removal of mass caused the surface pressure to decrease.

The area of hurricane force winds speeds in Hurricane Flossie increased on Tuesday.  Winds to hurricane force extended out 25 miles (40 km) from the center of Flossie’s circulation.  Winds to tropical storm force extended out 90 miles (145 km) from the center of Hurricane Flossie.

Hurricane Flossie will move through an environment very favorable for intensification during the next 24 hours.  Flossie will move over water where where the Sea Surface Temperatures are near 29°C.  It will move under the middle of an upper level ridge over Mexico and the adjacent part of the Eastern North Pacific Ocean.  The upper level winds are weak near the middle of the ridge and there will be little vertical wind shear.  Hurricane Flossie will intensify during the next 24 hours.  Flossie could intensify rapidly at times.  Hurricane Flossie is likely to strengthen to a major hurricane by Wednesday.

Hurricane Flossie will move around the southwestern part of a high pressure system over Mexico.  The high pressure system will steer the Flossie toward the northwest during the next 24 hours.  On its anticipated track, Hurricane Flossie will move parallel to the coast of southwestern Mexico.  Flossie is likely to move south of Baja California on Wednesday night.

Bands in the northeastern side of Hurricane Flossie will bring gusty winds and locally heavy rain to parts of the coast of southwestern Mexico.  The heaviest rain will fall in parts of Guerrero, Michoacan, Colima, and Jalisco.  Heavy rain could cause flash floods in some locations.

Flossie Intensifies to a Hurricane South of Mexico

Former Tropical Storm Flossie intensified to a hurricane over the Eastern North Pacific Ocean south of Mexico on Monday night.  At 11:00 p.m. EDT on Monday the center of Hurricane Flossie was located at latitude 16.5°N and longitude 104.3°W which put the center about 175 miles (280 km) south of Manzanillo, Mexico.  Flossie was moving toward the west-northwest at 10 m.p.h. (16 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 988 mb.

A Tropical Storm Warning is in effect for the portion of the coast from Punta San Telmo to Playa Perula, Mexico.

A Tropical Storm Watch is in effect for the portion of the coast from Playa Perula to Cabo Corrientes, Mexico.  A Tropical Storm Watch is in effect for the portion of the coast from Punta San Telmo to Zihuatanejo, Mexico.

Former Tropical Storm Flossie intensified steadily on Monday and the U.S. National Hurricane Center upgraded Flossie to a hurricane on Monday night.

The inner end of a rainband wrapped around the northern side of the center of Hurricane Flossie.  An eye appeared to be forming at the center of Flossie’s circulation.  The strongest winds were occurring in the inner end of the rainband that wrapped around the center of Hurricane Flossie.  Other bands of showers and thunderstorms were revolving around the center of Flossie’s circulation.  Storms near the center of Flossie generated upper level divergence that pumped mass away from the hurricane in all directions. The removal of mass caused the surface pressure to decrease.

The distribution of winds speeds in Hurricane Flossie became more symmetrical on Monday.  Winds to hurricane force extended out 15 miles (25 km) from the center of Flossie’s circulation.  Winds to tropical storm force extended out 115 miles (185 km) from the center of Hurricane Flossie.

Hurricane Flossie will move through an environment very favorable for intensification during the next 24 hours.  Flossie will move over water where where the Sea Surface Temperatures are near 30°C.  It will move under the middle of an upper level ridge over southern Mexico and the adjacent part of the Eastern North Pacific Ocean.  The upper level winds are weak near the middle of the ridge and there will be little vertical wind shear.  Hurricane Flossie will intensify during the next 24 hours.  Flossie could intensify rapidly at times.  Hurricane Flossie could strengthen to a major hurricane.

Hurricane Flossie will move around the southwestern part of a high pressure system over Mexico.  The high pressure system will steer the Flossie toward the northwest during the next 24 hours.  On its anticipated track, Hurricane Flossie will move parallel to the coast of southwestern Mexico.

Bands in the northern side of Hurricane Flossie will bring gusty winds and locally heavy rain to parts of the coast of southwestern Mexico.   The heaviest rain will fall in parts of Guerrero, Michoacan, Colima, and Jalisco.  Heavy rain could cause flash floods in some locations.

A Tropical Storm Warning was in effect for the portion of the coast from El Roblito to Mazatlan, Mexico. A Tropical Storm Warning was also in effect for the portion of the coast from Manzanillo to Punta San Telmo, Mexico.

Hurricane Lidia rapidly intensified to Category 4 on the Saffir-Simpson Scale prior to making landfall on the west coast of Mexico. Winds to hurricane force extended out 30 miles (50 km) from the center of Lidia. Winds to tropical storm force extended out 140 miles (220 km) from the center of circulation. The Hurricane Intensity Index (HII) was 28.3. The Hurricane Size Index (HSI) was 9.8 and the Hurricane Wind Intensity Size Index (HWISI) was 38.1. Hurricane Lidia was similar in size and intensity to Hurricane Charley when Charley hit Southwest Florida in 2004.

An upper level trough west of Baja California will steer Hurricane Lidia toward the northeast during the next 24 hours. On its anticipated track, Hurricane Lidia will move quickly inland over Jalisco. Lidia will weaken steadily as it moves farther inland. Even though it will weaken, Hurricane Lidia be capable of causing severe damage. Lidia will bring strong, gusty winds and locally heavy rain. Regional outages of electricity are likely. Heavy rain will fall in Jalisco and Nayarit. The heavy rain is likely to cause flash floods in some locations. Hurricane Lidia could cause a storm surge of up to 13 feet (4 meters) along the coast of Jalisco.

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.

Beatriz Rapidly Intensifies to a Hurricane

Former Tropical Storm Beatriz rapidly intensified to a hurricane over the Eastern North Pacific Ocean south of Lazaro Cardenas, Mexico on Friday morning. At 11:00 a.m. EDT on Friday the center of Hurricane Beatriz was located at latitude 17.3°N and longitude 102.3°W which put it about 50 miles (80 km) south of Lazaro Cardenas, Mexico. Beatriz was moving toward the northwest 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 991 mb.

A Hurricane Warning was in effect for the portion of the coast from Zihuatenajo to Cabo Corrientes, Mexico. The Hurricane Warning included Manzanillo. A Hurricane Watch was in effect for the portion of the coast from Cabo Corrientes to Punta Mita, Mexico. Tropical Storm Warnings were in effect for the portions of the coast from Tecpan de Galeana to Zihuatenajo and from Cabo Corrientes 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.

Former Tropical Storm Beatriz rapidly intensified to a hurricane on Friday morning. The inner end of a rainband wrapped around the center of Beatriz’ circulation. Visible and microwave satellite images showed that an eye was forming at the center of Hurricane Beatriz. Bands of showers and thunderstorms were revolving around the core of Beatriz. Storms near the core generated upper level divergence that pumped mass away from the hurricane.

The circulation around Hurricane Beatriz was small. Winds to hurricane force extended out 15 miles (25 km) in the northeastern quadrant of Beatriz’ circulation. Winds to tropical storm force extended out 70 miles (110 km) from the center of circulation.

Hurricane Beatriz will move through an environment favorable for intensification during the next 12 hours. Beatriz will move over water where the Sea Surface Temperatures are near 30˚C. It will move under the southwestern part of an upper level ridge over Mexico and the southern U.S. The upper level ridge will produce easterly winds that will blow toward the top of Hurricane Beatriz. However, the winds in the lower levels of the atmosphere will also blow from the east. So, there will be little vertical wind shear. Hurricane Beatriz is likely to intensify during the next 12 hours. Beatriz will be near the coast of Mexico on Saturday. If the core of Hurricane Beatriz remains over the Eastern North Pacific Ocean, then it will be in an environment favorable for intensification. If Beatriz moves over land on Saturday, it will weaken quickly.

The upper level ridge over Mexico and the southern U.S. will steer Hurricane Beatriz toward the northwest during the next 24 hours. On its anticipated track, Hurricane Beatriz will move very close to the coast of Mexico. The center of Beatriz could be near Manzanillo by Friday night. Beatriz could make landfall near Manzanillo or the center of circulation could pass just to the west of Manzanillo. Bands in the northern side of Hurricane Beatriz will bring strong winds and locally heavy rain to parts of the west coast of Mexico. Beatriz will bring strong winds and locally heavy rain to Guerrero, Michoacan, Colima and Jalisco. Heavy rain could cause flash floods in some locations.

Elsewhere over the Eastern North Pacific Ocean, Hurricane Adrian intensified south-southwest of Baja California. At 11:00 a.m. EDT on Friday the center of Hurricane Adrian was located at latitude 17.3°N and longitude 112.2°W which put it about 415 miles (665 km) south-southwest of the southern tip of Baja California. Adrian was moving toward the northwest at 7 m.p.h. (11 km/h). The maximum sustained wind speed was 105 m.p.h. (165 km/h) and there were wind gusts to 125 m.p.h. (200 km/h). The minimum surface pressure was 970 mb.

Former Tropical Depression Two-E strengthened to Tropical Storm Beatriz over the Eastern North Pacific Ocean near Mexico on Thursday afternoon. A distinct low level center of circulation was evident on visible satellite images of Tropical Storm Beatriz. Bands of showers and thunderstorms were revolving around the center of Beatriz’ circulation. Storm near the center of circulation generated upper level divergence that pumped mass away from the tropical storm. Winds to tropical storm force extended out 45 miles (75 km) in the northeastern quadrant of Tropical Storm Beatriz. The winds in the other parts of Beatriz’ circulation were blowing at less than tropical storm force.

Tropical Storm Beatriz will move through an environment favorable for intensification during the next 24 hours. Beatriz will move over water where the Sea Surface Temperatures are near 30˚C. It will move under the southwestern part of an upper level ridge over Mexico and the southern U.S. The upper level ridge will produce easterly winds that will blow toward the top of Tropical Storm Beatriz. However, the winds in the lower levels of the atmosphere will also blow from the east. So, there will be little vertical wind shear. Tropical Storm Beatriz will intensify during the next 24 hours. Beatriz could intensify rapidly at times. Tropical Storm Beatriz could strengthen to a hurricane during the next 24 hours.

The upper level ridge over Mexico and the southern U.S. will steer Tropical Storm Beatriz toward the northwest during the next 36 hours. On its anticipated track, Tropical Storm Beatriz will move closer to the coast of Mexico. The center of Beatriz could be near Manzanillo by Friday evening. Beatriz could be a hurricane when it gets near Manzanillo. Bands in the northern side of Tropical Storm Beatriz could bring gusty winds and locally heavy rain to parts of the west coast of Mexico. Locally heavy rain could fall in parts of Oaxaca and Guerrero. Strong winds and locally heavy rain could affect Michoacan, Colima and Jalisco. Heavy rain could cause flash floods in some locations.
