Tropical Storm Henriette Forms Southwest of Baja California

Tropical Storm Henriette formed over the Eastern North Pacific Ocean southwest of Baja California on Monday afternoon.  At 5:00 p.m. EDT on Monday the center of Tropical Storm Henriette was located at latitude 14.8°N and longitude 120.6°W which put the center about 895 miles (1440 km) southwest of the southern tip of Baja California.  Henriette was moving toward the west-northwest at 15 m.p.h. (24 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 1004 mb.

A low pressure system over the Eastern North Pacific Ocean southwest of Baja California strengthened on Monday afternoon and the U.S. National Hurricane Center designated the system as Tropical Storm Henriette.

The distribution of thunderstorms in Tropical Storm Henriette was asymmetrical.  Thunderstorms were occurring in bands in the western side of Henriette’s circulation.  Bands in the eastern side of Tropical Storm Henriette consisted primarily of showers and lower clouds.  Storms near the center of Henriette generated upper level divergence that pumped mass away to the west of the tropical storm.  The removal of mass caused the surface pressure to decrease.

The circulation around Tropical Storm Henriette was small.  Winds to tropical storm force extended out 45 miles (75 km) from the center of Henriette’s circulation.

Tropical Storm Henriette will move through an environment somewhat favorable for intensification during the next 24 hours.  Henriette will move over water where the Sea Surface Temperatures are near 27°C.  It will move under the southern side of an upper level ridge over the Eastern North Pacific Ocean.  The upper level ridge will produce easterly winds that will blow toward the top of Henriette’s circulation.  Those winds will cause some vertical wind shear.  The vertical wind shear will inhibit intensification, but the wind shear will not be enough to prevent intensification.  Tropical Storm Henriette will intensify during the next 24 hours.

Tropical Storm Henriette will move around the southern side of a high pressure system over the Eastern North Pacific Ocean.  The high pressure system will steer Henriette toward the west-northwest during the next 24 hours.  On its anticipated track, Tropical Storm Henriette will move farther away from Baja California.

 

Gil Strengthens to a Hurricane

Former Tropical Storm Gil strengthened to a hurricane over the Eastern North Pacific Ocean southwest of Baja California on Friday.  At 11:00 p.m. EDT on Friday the center of Hurricane Gil was located at latitude 16.5°N and longitude 125.1°W which put the center about 1080 miles (1740 km) west-southwest of the southern tip of Baja California.  Gil was moving toward the west-northwest at 20 m.p.h. (32 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.

Former Tropical Storm Gil strengthened to a hurricane on Friday.  The inner end of a rainband wrapped around the western and southern sides of the center of Gil’s circulation.  Bands of showers and thunderstorms were revolving around the center of Hurricane Gil.  Storms near the center of Gil generated upper level divergence that pumped mass away from the hurricane.  The removal of mass caused the surface pressure to decrease.

The strongest winds were occurring in the northeastern part of Hurricane Gil.  Winds to hurricane force extended out 25 miles (40 km) in the northeastern quadrant of Gil’s circulation.  Winds to tropical storm force extended out 125 miles (200 km) from the center of Hurricane Gil.

Hurricane Gil will move through an environment somewhat favorable for intensification during the next 24 hours.  Gil will move over water where the Sea Surface Temperatures are near 27°C.  It will move through a region where there will be little vertical wind shear.  However, Gil will move into a region where there is very dry air.  The dry air will inhibit intensification.  Hurricane Gil could intensify during the next 24 hours if the dry air does not penetrate to the core of Gil’s circulation.

Hurricane Gil will move around the southern side of a high pressure system over the Eastern North Pacific Ocean.  The high pressure system will steer Gil toward the west-northwest during the next 24 hours.  On its anticipated track, Hurricane Gil will continue to move farther away from Baja California.

Elsewhere, former Tropical Storm Iona weakened to a tropical depression as it approached the International Date Line.  At 11:00 p.m. EDT on Friday the center of Tropical Depression Iona was located at latitude 15.8°N and longitude 179.5°W which put the center about 1465 miles (2355 km) west of Honolulu, Hawaii.  Iona was moving toward the west-northwest at 17 m.p.h. (28 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.

Tropical Storm Gil Forms South of Baja California

Tropical Storm Gil formed over the Eastern North Pacific Ocean south of Baja California on Wednesday night.  At 5:00 a.m. EDT on Thursday the center of Tropical Storm Gil was located at latitude 12.7°N and longitude 115.1°W which put the center about 785 miles (1260 km) south-southwest of the southern tip of Baja California.  Gil was moving toward the west at 15 m.p.h. (24 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 1004 mb.

A low pressure system over the Eastern North Pacific Ocean south of Baja California strengthened on Wednesday night and the U.S. National Hurricane Center designated the system as Tropical Storm Gil.

The circulation around Tropical Storm Gil was organizing quickly on Thursday morning.  Numerous thunderstorms formed near the center of Gil’s circulation.  Thunderstorms also developed in bands revolving around the center of Tropical Storm Gil.  Storms near the center of Gil generated upper level divergence that pumped mass away from the tropical storm.  The removal of mass caused the surface pressure to decrease.

The distribution of wind speed in Tropical Storm Gil was asymmetrical.  Winds to tropical storm force extended out 160 miles (260 km) in the eastern side of Gil’s circulation.  Winds to tropical storm force extended out 60 miles (95 km) in the western side of Tropical Storm Gil.

Tropical Storm Gil will move through an environment very favorable for intensification during the next 24 hours.  Gil will move over water where the Sea Surface Temperatures are near 28°C.   It will move under the southern side of an upper level ridge over the Eastern North Pacific Ocean.  The upper level ridge will produce easterly winds that will blow toward the top of Gil’s circulation.  However, the winds in the lower atmosphere will also blow from the east.  So, there will be little vertical wind shear.  Tropical Storm Gil will intensify during the next 24 hours.  Gil could intensify rapidly,  Tropical Storm Gil could strengthen to a hurricane by Friday.

Tropical Storm Gil will move around the southern side of a high pressure system over the Eastern North Pacific Ocean.  The high pressure system will steer Gil toward the west-northwest during the next 24 hours.  On its anticipated track, Tropical Storm Gil will move away from Baja California.

Elsewhere, Tropical Storm Iona moved quickly away from Hawaii.  At 5:00 a.m. EDT on Thursday the center of Tropical Storm Iona was located at latitude 12.3°N and longitude 166.9°W which put the center about 860 miles (1385 km) southwest of Honolulu, Hawaii.  Iona was moving toward the west at 23 m.p.h. (37 km/h).  The maximum sustained wind speed was 50 m.p.h. (80 km/h) and there were wind gusts to 65 m.p.h. (105 km/h).  The minimum surface pressure was 1001 mb.

Hurricane Flossie Weakens Rapidly

Hurricane Flossie weakened rapidly on Wednesday evening as it moved over the Eastern North Pacific Ocean south of Baja California.  At 11:00 p.m. EDT on Wednesday the center of Hurricane Flossie was located at latitude 19.8°N and longitude 110.2°W which put the center about 215 miles (345 km) south of Cabo San Lucas, Mexico.  Flossie was moving toward the northwest at 8 m.p.h. (13 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 986 mb.

Hurricane Flossie was weakening rapidly on Wednesday evening as it moved over cooler water south of Baja California.  Many of the thunderstorms in Flossie’s circulation were dissipating,  The bands revolving around the center of Hurricane Flossie consisted primarily of showers and lower clouds.  The dissipation of the thunderstorms in Flossie greatly reduced the upper level divergence.  Much less mass was being pumped away from Hurricane Flossie.  The continued convergence of mass in the lower levels of Flossie’s circulation caused the surface pressure to increase quickly.

The circulation around Hurricane Flossie was 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 70 miles (110 km) from the center of Hurricane Flossie.

Hurricane Flossie will move through an environment that will be unfavorable for intensification during the next 24 hours.  Flossie will move over water where where the Sea Surface Temperatures are near 23°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.  Even though there will be little vertical wind shear, the cooler water south of Baja California will cause Hurricane Flossie to continue to weaken on Thursday.

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 remain south of Baja California.

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.

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.

Tropical Depression Barry Brings Rain to Eastern Mexico

Tropical Depression Barry brought rain to eastern Mexico on Sunday night.  At 11:00 p.m. EDT on Sunday the center of Tropical Depression Barry was located at latitude 22.0°N and longitude 97.8°W which put the center about 15 miles (25 km) south-southeast of Tampico, Mexico.  Barry was moving toward the northwest at 9 m.p.h. (15 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. (55 km/h).  The minimum surface pressure was 1007 mb.

Former Tropical Storm Barry weakened to a tropical depression on Sunday night just before it made landfall on the coast of Mexico south of Tampico.  An upper level ridge over southern Mexico produced strong westerly winds that blew toward the top of Barry’s circulation.  Those winds caused strong vertical wind shear.  The strong vertical wind shear caused Barry to weaken to a tropical depression.

Tropical Depression Barry will move around the southwestern part of a high pressure system that extends from the Atlantic Ocean to over the Gulf of Mexico.  The high pressure system will steer Barry toward the northwest during the next 24 hours.  On its anticipated track, Tropical Depression Barry will move inland over Mexico west of Tampico.

Tropical Depression Barry is likely to weaken quickly as it moves farther inland.  Even though Barry will weaken quickly, it could drop heavy rain on parts of the state of Veracruz.  Heavy rain could cause flash floods in some locations, especially in mountainous areas.

Depression Strengthens to Tropical Storm Flossie

Former Tropical Depression Six-E strengthened to Tropical Storm Flossie over the Eastern North Pacific Ocean south of Mexico on Sunday.  At 11:00 a.m. EDT on Sunday the center of Tropical Storm Flossie was located at latitude 13.4°N and longitude 99.9°W which put the center about 240 miles (390 km) south of Acapulco, Mexico.   Flossie was moving toward the west at 9 m.p.h. (15 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 1005 mb.

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

Former Tropical Depression Six-E continued to strengthen on Sunday.  The U.S. National Hurricane Center upgraded former Tropical Depression Six-E to Tropical Storm Flossie.

The circulation around Tropical Storm Flossie continue to get more organized on Sunday.  More thunderstorms developed near the center of Flossie’s circulation.  More thunderstorms also formed in bands revolving around the center of Tropical Storm Flossie.  Storms near the center of Flossie generated upper level divergence that pumped mass away from the tropical depression.  The removal of mass caused the surface pressure to decrease.

Tropical Storm 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 southeastern 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.  Tropical Storm Flossie will intensify during the next 24 hours.  Flossie could intensify rapidly at times.  Tropical Storm Flossie is likely to strengthen to a hurricane on Monday.

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

Bands in the northern side of Tropical Storm Flossie will bring gusty winds and locally heavy rain to parts of the coast of southern Mexico.  Heavy rains could cause flash floods in some locations.

Depression Strengthens to Tropical Storm Barry

Former Tropical Depression Two strengthened to Tropical Storm Barry over the western Bay of Campeche on Sunday.  At 11:00 a.m. EDT on Sunday the center of Tropical Storm Barry was located at latitude 20.4°N and longitude 96.2°W which put the center about 90 miles (145 km) east-southeast of Tuxpan, Mexico.   Barry was moving toward the northwest at 6 m.p.h. (10 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 1006 mb.

A Tropical Storm Warning is in effect for the portion of the coast from Boca de Catan to Tecolutla, Mexico.

A U.S. Air Force Reserve Hurricane Hunter aircraft found that former Tropical Depression Two had strengthened to Tropical Storm Barry.  The aircraft found a distinct low level center of circulation.  It also found an area where the sustained wind speed was at tropical storm force.  Based on data collected by the reconnaissance flight, the U.S. National Hurricane Center upgraded the system to Tropical Storm Barry.

The circulation around Tropical Storm Barry was exhibiting evidence of strong vertical wind shear.  Thunderstorms were occurring in bands in the eastern side of Barry’s circulation.  Bands in the western side of Tropical Storm Barry consisted primarily of showers and lower clouds.

The distribution of wind speeds in Tropical Storm Barry was also asymmetrical.  Winds to tropical storm force extended out 35 miles (55 km) in the northeastern quadrant of Barry’s circulation.  The winds in the other parts of Tropical Storm Barry were blowing at less than tropical storm force.

Tropical Storm Barry will move through an environment marginally favorable for intensification during the next few hours.  Barry will move over water where where the Sea Surface Temperatures are near 28°C.  It will move under the northern part of an upper level ridge over southern Mexico.  The upper level ridge will produce strong westerly winds that will blow toward the top of Barry’s circulation.  Those winds will cause strong vertical wind shear. The vertical wind shear will inhibit further intensification, but the wind shear may not be enough to prevent some additional intensification.  Tropical Storm Barry could intensify a little more during the next few hours.

Tropical Storm Barry will move around the southwestern part of a high pressure system that extends from the Atlantic Ocean to over the Gulf of Mexico.  The high pressure system will steer Barry toward the northwest during the next 24 hours.  On its anticipated track, Tropical Storm Barry will make landfall between Tuxpan and Tampico in a few hours.

Tropical Storm Barry will bring gusty winds and locally heavy rain to coastal sections of the state of Veracruz.  Heavy rain could cause flash floods, especially in mountainous areas.
