Tropical Storm Ivo Moves South of Baja California

Tropical Storm Ivo moved south of Baja California on Friday.  At 5:00 p.m. EDT on Friday the center of Tropical Storm Ivo was located at latitude 20.4°N and longitude 111.2°W which put the center about 190 miles (310 km) south-southwest of the southern tip of Baja California.  Ivo was moving toward the west at 13 m.p.h. (21 km/h).  The maximum sustained wind speed was 65 m.p.h. (105 km/h) and there were wind gusts to 80 m.p.h. (130 km/h).  The minimum surface pressure was 999 mb.

Tropical Storm Ivo exhibited much more organization on Friday after it moved south of Baja California.  The inner end of a rainband wrapped around the western side of the center of Ivo’s circulation.  Other bands of showers and thunderstorms were revolving around the center of Tropical Storm Ivo.  Storms near the center of Ivo generated upper level divergence that pumped mass away from the tropical storm.  The removal of mass caused the surface pressure to decrease.

The circulation around Tropical Storm Ivo was small.  Winds to tropical storm force extended out 35 miles (55 km) from the center of Ivo’s circulation.

Tropical Storm Ivo will move through an environment mostly favorable for intensification during the next 24 hours.  Ivo 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 Mexico and the Eastern North Pacific Ocean.  The upper level ridge will produce easterly winds that will blow toward the top of Ivo’s circulation.  However, the winds in the lower atmosphere will also blow from the east.  Since the winds in the upper and lower levels of the atmosphere will blow from the same direction, there will be less vertical wind shear.  Tropical Storm Ivo is likely to intensify during the next 24 hours.  Ivo could strengthen to a hurricane on Saturday.  Ivo will move over cooler water on Sunday which will cause it to weaken.

Tropical Storm Ivo will move around the southern side of a high pressure system that is over Mexico and the eastern North Pacific Ocean.  The high pressure system will steer Ivo toward the west during the next 24 hours.  On its anticipated track, Tropical Storm Ivo will move away from Baja California during the weekend.

Tropical Storm Ivo Moves Southeast of Baja California

Tropical Storm Ivo moved southeast of Baja California on Thursday evening.  At 5:00 p.m. EDT on Thursday the center of Tropical Storm Ivo was located at latitude 19.7°N and longitude 107.3°W which put the center about 275 miles (445 km) southeast of the southern tip of Baja California.  Ivo was moving toward the northwest at 22 m.p.h. (35 km/h).  The maximum sustained wind speed was 60 m.p.h. (95 km/h) and there were wind gusts to 75 m.p.h. (120 km/h).  The minimum surface pressure was 1001 mb.

Even though Tropical Storm Ivo strengthened on Thursday, its structure did not change a lot.  Thunderstorms were still forming near the center of Ivo’s circulation.  Thunderstorms were also occurring in bands in the southern and eastern parts of Tropical Storm Ivo.  Bands in the northern and western parts of Ivo’s circulation consisted primarily of showers and lower clouds.

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

Tropical Storm Ivo will move through an environment mostly favorable for intensification during the next 24 hours.  Ivo will move over water where the Sea Surface Temperatures are near 29°C.  It will move under the southern side of an upper level ridge over Mexico.  The upper level ridge will produce easterly winds that will blow toward the top of Ivo’s circulation.  However, the winds in the lower atmosphere will also blow from the east.  Since the winds in the upper and lower levels of the atmosphere will blow from the same direction, there will be less vertical wind shear.  Even though Tropical Storm Ivo will move through an environment most favorable for intensification, Ivo may not intensify a lot on Friday as long as it continues to move quickly toward the west-northwest.  If Tropical Storm Ivo starts to move more slowly, then it could intensify again.

Tropical Storm Ivo will move around the southern side of a high pressure system that is over Mexico.  The high pressure system will steer Ivo toward the west-northwest during the next 24 hours.  On its anticipated track, Tropical Storm Ivo will move south of Baja California on Friday.

Elsewhere over the Eastern North Pacific Ocean, Tropical Storm Henriette weakened slowly as it approached the Central Pacific.  At 5:00 p.m. EDT on Thursday the center of Tropical Storm Henriette was located at latitude 19.1°N and longitude 138.4°W which put the center about 1090 miles (1750 km) east Hilo, Hawaii.  Henriette was moving toward the west at 16 m.p.h. (26 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 1007 mb.

Tropical Storm Ivo Forms South of Mexico

Tropical Storm Ivo formed over the Eastern North Pacific Ocean on Wednesday afternoon.  At 5:00 p.m. EDT on Wednesday the center of Tropical Storm Ivo was located at latitude 14.2°N and longitude 99.1°W which put the center about 195 miles (310 km) south-southeast Acapulco, Mexico.  Ivo was moving toward the west-northwest at 22 m.p.h. (35 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 1008 mb.

A low pressure system over the Eastern North Pacific Ocean south of Mexico strengthened on Wednesday afternoon and the U.S. National Hurricane Center designated the system as Tropical Storm Ivo.

The circulation around Tropical Storm Ivo organized quickly on Wednesday afternoon.  Thunderstorms developed near the center of Ivo’s circulation.  Thunderstorms also formed in bands revolving around the center of Tropical Storm Ivo.  Storms near the center of Ivo began to generate upper level divergence that pumped mass away from the tropical storm.

The circulation around Tropical Storm Ivo was small.  Winds to tropical storm force extended out 25 miles (40 km) in the northern side of Ivo’s circulation.  The winds in the southern side of Tropical Storm Ivo were blowing at less than tropical storm force.

Tropical Storm Ivo will move through an environment mostly favorable for intensification during the next 24 hours.  Ivo will move over water where the Sea Surface Temperatures are near 29°C.  It will move under the southern side of an upper level ridge over Mexico.  The upper level ridge will produce easterly winds that will blow toward the top of Ivo’s circulation.  However, the winds in the lower atmosphere will also blow from the east.  Since the winds in the upper and lower levels of the atmosphere will blow from the same direction, there will be less vertical wind shear.  Tropical Storm Ivo is likely to strengthen during the next 24 hours.

Tropical Storm Ivo will move around the southern side of a high pressure system that is over Mexico.  The high pressure system will steer Ivo toward the west-northwest during the next 24 hours.  On its anticipated track, Tropical Storm Ivo will move parallel to the coast of southern Mexico.

Bands in the northern side of Ivo’s circulation could drop heavy rain on parts of southern Mexico.  Heavy rain could cause flash floods in Guerrero, Michoacan, and Colima.

Elsewhere over the Eastern North Pacific Ocean, Tropical Storm Henriette continued to churn toward the Central Pacific.  At 5:00 p.m. EDT on Wednesday the center of Tropical Storm Henriette was located at latitude 18.1°N and longitude 131.3°W which put the center about 1555 miles (2505 km) east Hilo, Hawaii.  Henriette was moving toward the west at 16 m.p.h. (26 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 1005 mb.

Tropical Storm Henriette Churns Westward

Tropical Storm Henriette churned westward over the Eastern North Pacific Ocean on Tuesday.  At 5:00 p.m. EDT on Tuesday the center of Tropical Storm Henriette was located at latitude 17.0°N and longitude 125.6°W which put the center about 1095 miles (1765 km) west-southwest of the southern tip of Baja California.  Henriette was moving toward the west-northwest at 16 m.p.h. (26 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 1003 mb.

The structure of Tropical Storm Henriette did not change much on Tuesday.  The distribution of thunderstorms in Tropical Storm Henriette continued to be 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 on the western side of the center of Henriette generated upper level divergence that pumped mass away to the west of the tropical storm.  The removal of mass in the upper levels was balanced by an inflow of mass in the lower levels of the atmosphere.  The balance of outflow and inflow of mass caused the surface pressure to remain nearly constant.

The size of the circulation around Tropical Storm Henriette increased a little on Tuesday.  Winds to tropical storm force extended out 70 miles (110 km) from the center of Henriette’s circulation.

Tropical Storm Henriette will move through an environment marginally favorable for intensification during the next 24 hours.  Henriette will move over water where the Sea Surface Temperatures are near 26°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.  The intensity of Tropical Storm Henriette is likely to remain nearly constant 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 continue to move farther away from Baja California.

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.

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.
