Tropical Storm Amanda Spins Southwest of Baja California

Leave a reply

Tropical Storm Amanda continued to spin over the Eastern North Pacific Ocean far to the southwest of Baja California on Friday.  At 5:00 p.m. EDT on Friday the center of Tropical Storm Amanda was located at latitude 13.1°N and longitude 134.1°W which put the center about 1725 miles (2775 km) west-southwest of the southern tip of Baja California.  Amanda was moving toward the west at 5 m.p.h. (8 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.

Tropical Storm Amanda started to weaken on Friday as it spun far to the southwest of Baja California.  Amanda moved into a region with drier, more stable air.  The drier air and more vertical wind shear caused some of the thunderstorms in Tropical Storm Amanda to dissipate.  Thunderstorms were still occurring in bands west of the center of Amanda’s circulation.  Bands in the other parts of Tropical Storm Amanda consisted primarily of showers and lower clouds.

Thunderstorms west of the center of Tropical Storm Amanda generated less upper level divergence.  The removal of mass in the upper levels of the atmosphere was less than the convergence of mass in the lower levels.  So, the net inflow of mass caused the surface pressure to increase slowly.

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

Tropical Storm Amanda will move through an environment unfavorable for intensification during the next 24 hours.  Amanda will move over water where the Sea Surface Temperatures are near 27°C.  It will move under the western part of an upper level ridge that is west of Mexico.  The upper level ridge will produce southeasterly winds that will blow toward the top of Amanda’s circulation.  Those winds will cause moderate vertical wind shear. In addition, Tropical Storm Amanda will continue to move through a region of drier air.  The vertical wind shear and the drier air will cause Tropical Storm Amanda to continue to weaken during the next 24 hours.

Tropical Storm Amanda will move around the southern part of a high pressure system that is over the Eastern North Pacific Ocean.  The high pressure system will steer Amanda slowly toward the west-southwest during the next 24 hours.  On its anticipated track, Tropical Storm Amanda will remain far to the southwest of Baja California.

Tropical Storm Amanda Strengthens a Little

Tropical Storm Amanda strengthened a little on Thursday as it continued to spin over the Eastern North Pacific Ocean far to the southwest of Baja California.  At 5:00 p.m. EDT on Thursday the center of Tropical Storm Amanda was located at latitude 12.7°N and longitude 131.1°W which put the center about 1560 miles (2510 km) west-southwest of the southern tip of Baja California.  Amanda was moving toward the west-northwest at 9 m.p.h. (15 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.

Even though Tropical Storm Amanda strengthened a little on Thursday, the distribution of thunderstorms in Amanda continued to be asymmetrical.  Thunderstorms were occurring mainly in bands in the western half of Amanda’s circulation.  Bands in the eastern half of Tropical Storm Amanda consisted primarily of showers and lower clouds.  Storms near the center of Amanda generated upper level divergence that pumped mass away to the north of the tropical storm.  The removal of mass caused the surface pressure to decrease slowly.

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

Tropical Storm Amanda will move through an environment marginally favorable for intensification during the next 24 hours.  Amanda will move over water where the Sea Surface Temperatures are near 28°C.  It will move under the western part of an upper level ridge that is west of Mexico.  The upper level ridge will produce southeasterly winds that will blow toward the top of Amanda’s circulation.  Those winds will cause moderate vertical wind shear. The vertical wind shear will inhibit intensification, but the wind shear may not be enough to prevent intensification.  Tropical Storm Amanda could intensify a little more during the next 24 hours.  Amanda will move into a region where the upper level winds are stronger and where there will be more vertical wind shear during the weekend.  Tropical Storm Amanda will start to weaken when the vertical wind shear in creases.

Tropical Storm Amanda will move around the southwestern part of a high pressure system that is over the Eastern North Pacific Ocean.  The high pressure system will steer Amanda slowly toward the west-northwest during the next 24 hours.  On its anticipated track, Tropical Storm Amanda will remain far to the southwest of Baja California.

Former Tropical Depression One-E strengthened to Tropical Storm Amanda far to the southwest of Baja California on Wednesday morning.  At 11:00 a.m. EDT on Wednesday the center of Tropical Storm Amanda was located at latitude 10.6°N and longitude 128.2°W which put the center about 1475 miles (2375 km) west-southwest of the southern tip of Baja California.  Amanda was moving toward the northwest at 8 m.p.h. (13 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.

Former Tropical Depression One-E strengthened far to the southwest of Baja California on Wednesday morning and the U.S. National Hurricane Center designated the system as Tropical Storm Amanda.

More thunderstorms formed just to the west of the center of Tropical Storm Amanda on Wednesday morning.  Other thunderstorms were occurring in bands in the northern and western parts of Amanda’s circulation.  Bands in the southern and eastern parts of Tropical Storm Amanda still consisted primarily of showers and lower clouds.  Storms near the center of Tropical Storm Amanda generated upper level divergence that pumped mass away to the north of the tropical storm.  The removal of mass caused the surface pressure to decrease slowly.

The circulation around Tropical Storm Amanda was small.  Winds to tropical storm force extended out 60 miles (95 km) in the northern half of Amanda’s circulation.  The winds in the southern half of Tropical Storm Amanda were blowing at less than tropical storm force.

Tropical Storm Amanda will move through an environment favorable for intensification during the next 24 hours.  Amanda will move over water where the Sea Surface Temperatures are near 28°C.  It will move under the western part of an upper level ridge that is west of Mexico. The upper level ridge will produce southerly winds that will blow toward the top of Amanda’s circulation.  Those winds will cause moderate vertical wind shear.  The vertical wind shear will inhibit intensification, but the wind shear will not be enough to prevent intensification.  Tropical Storm Amanda will intensify during the next 24 hours.

Tropical Storm Amanda will move around the southwestern part of a high pressure system that is over the Eastern North Pacific Ocean.  The high pressure system will steer Amanda slowly toward the northwest during the next 24 hours.  On its anticipated track, Tropical Storm Amanda will remain far to the southwest of Baja California during the next few days.

Tropical Depression One-E formed over the Eastern North Pacific Ocean far to the southwest of Baja California on Tuesday afternoon.  At 5:00 p.m. EDT on Tuesday the center of Tropical Depression One-E was located at latitude 9.4°N and longitude 126.7°W which put the center about 1450 miles (2335 km) southwest of the southern tip of Baja California.  The tropical depression was moving toward the west at 3 m.p.h. (5 km/h).  The maximum sustained wind speed was 30 m.p.h. (50 km/h) and there were wind gusts to 40 m.p.h. (65 km/h).  The minimum surface pressure was 1008 mb.

A low pressure system over the Eastern North Pacific Ocean southwest of Baja California strengthened on Tuesday afternoon and the U.S. National Hurricane Center designated the system as Tropical Depression One-E.

The distribution of thunderstorms in Tropical Depression One-E was asymmetrical.  Thunderstorms were occurring in bands in the northern half of the tropical depression.  Bands in the southern half of Tropical Depression One-E consisted primarily of showers and lower clouds.  Storms near the center of Tropical Depression One-E began to generate upper level divergence that pumped mass away from the tropical depression.  The removal of mass caused the surface pressure to start to decrease slowly.

Tropical Depression One-E will move through an environment favorable for intensification during the next 24 hours.  The tropical depression will move over water where the Sea Surface Temperatures are near 28°C.  It will move under the western part of an upper level ridge that is west of Mexico.  The upper level ridge will produce southerly winds that will blow toward the top of the tropical depression.  Those winds will cause moderate vertical wind shear.  The vertical wind shear will inhibit intensification, but the wind shear will not be enough to prevent intensification.  Tropical Depression One-E is likely to intensify to a tropical storm during the next 24 hours.

Tropical Depression One-E will move around the southwestern part of a high pressure system that is over the Eastern North Pacific Ocean.  The high pressure system will steer the tropical depression slowly toward the northwest during the next 24 hours.  On its anticipated track, Tropical Depression One-E will remain far to the southwest of Baja California during the next few days.

Tropical Storm Sonia Spins Southwest of Baja California

Tropical Storm Sonia continued to spin over the Eastern North Pacific Ocean southwest of Baja California on Sunday.  At 11:00 a.m. EDT on Sunday the center of Tropical Storm Sonia was located at latitude 13.7°N and longitude 119.9°W which put the center about 910 miles (1470 km) southwest of the southern tip of Baja California.  Sonia was moving toward the west at 3 m.p.h. (5 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 1002 mb.

An upper level trough over the Eastern North Pacific Ocean was producing southerly winds that were blowing toward the top of Tropical Storm Sonia.  Those winds were causing moderate vertical wind shear.  The moderate vertical wind shear was causing the distribution of thunderstorms in Tropical Storm Sonia to be asymmetrical.  Thunderstorms were occurring in bands in the northern half of Sonia’s circulation.  Bands in the southern half of Tropical Storm Sonia consisted primarily of showers and lower clouds.

The circulation around Tropical Storm Sonia was small.  Winds to tropical storm force extended out 60 miles (95 km) from the center of Sonia’s circulation.

Tropical Storm Sonia will move through an environment that will be marginally favorable for intensification during the next 24 hours.  Sonia will move over water where the Sea Surface Temperatures are near 27°C.  However, the upper level trough over the Eastern North Pacific Ocean will continue to cause moderate vertical wind shear.  The vertical wind shear will inhibit intensification, but the wind shear may not be enough to prevent intensification.  Tropical Storm Sonia could intensify a little during the next 24 hours.

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

Tropical Storm Sonia Forms Southwest of Baja California

Tropical Storm Sonia formed over the Eastern North Pacific Ocean southwest of Baja California early on Saturday.  At 5:00 a.m. EDT on Saturday the center of Tropical Storm Sonia was located at latitude 13.3°N and longitude 117.6°W which put the center about 835 miles (1340 km) southwest of the southern tip of Baja California.  Sonia 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 1006 mb.

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

More thunderstorms developed near the center of Tropical Storm Sonia early on Saturday.  Thunderstorms also were forming in bands revolving around the center of Sonia’s circulation.  Storms near the center of Sonia started to generate upper level divergence that pumped mass away from the tropical storm.

The circulation around Tropical Storm Sonia was small.  Winds to tropical storm force extended out 60 miles (95 km) in the northern half of Sonia’s circulation.  Winds to tropical storm force extended out 25 miles (40 km) in the southern side of Tropical Storm Sonia.

Tropical Cyclone Sonia will move through an environment that is favorable for intensification during the next 24 hours.  Sonia will move over water where the Sea Surface Temperatures are near 27°C.  It will move under the eastern side of an upper level trough that is over the Eastern North Pacific Ocean.  The upper level trough will produce southwesterly winds that will blow toward the top of Sonia’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 Sonia will intensify during the next 24 hours.

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

Raymond Weakens to a Tropical Depression

Former Tropical Storm Raymond weakened to a tropical depression south of Baja California on Saturday.  At 5:00 p.m. EDT on Saturday the center of Tropical Depression Raymond was located at latitude 22.5°N and longitude 109.9°W which put the center about 30 miles (50 km) south of the southern tip of Baja California.  Raymond was moving toward the north-northwest at 14 m.p.h. (22 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 1005 mb.

Former Tropical Storm Raymond weakened to a tropical depression south of Baja California on Saturday.  Most of the thunderstorms in Raymond’s circulation dissipated.  The bands revolving around the center of Tropical Depression Raymond consisted primarily of showers and lower clouds.  There were no thunderstorms near the center of Raymond’s circulation to generate upper level divergence.  Converging winds in the lower levels of the atmosphere caused the surface pressure to increase.

Tropical Depression Raymond will move through an environment that will be unfavorable for intensification during the next 24 hours.  Raymond will move over water where the Sea Surface Temperatures are near 28°C.  It will move under the southwestern part of an upper level ridge that is over Mexico.  The upper level ridge will produce easterly winds that will blow toward the top of Raymond’s circulation.  Those winds will cause strong vertical wind shear.  The strong wind shear will cause Tropical Depression Raymond to continue to weaken.

Tropical Depression Raymond will move around the western side of a high pressure system that is over Mexico.  The high pressure system will steer Raymond toward the north during the next 24 hours.  On its anticipated track, Tropical Depression Raymond will move across the southern part of Baja California on Saturday night.

Tropical Depression Raymond will bring gusty winds and isolated heavy rain to parts of southern Baja California.

Tropical Storm Raymond Moves West of Mexico

Tropical Storm Raymond moved west of Mexico on Friday afternoon.  At 5:00 p.m. EDT on Friday the center of Tropical Storm Raymond was located at latitude 19.1°N and longitude 106.5°W which put the center about 145 miles (230 km) west of Manzanillo, Mexico.  Raymond was moving toward the northwest at 17 m.p.h. (28 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 1000 mb.

A Tropical Storm Warning was in effect for the portion of the coast from Manzanillo to Cabo Corrientes, Mexico.  A Tropical Storm Warning was in effect for Las Islas Marias.  A Tropical Storm Warning was in effect for the portion of the coast from Los Barriles to Santa Fe, Mexico.

The distribution of thunderstorms in Tropical Storm Raymond was still asymmetrical on Friday afternoon. Thunderstorms were occurring in bands in the southern and western parts of Raymond’s circulation.  Bands in the northern and eastern parts of Tropical Storm Raymond consisted primarily of shower and lower clouds.  Storms near the center of Raymond generated some upper level divergence that pumped mass away to the west of the tropical storm.

The circulation around Tropical Storm Raymond was small.  Winds to tropical storm force extended out 80 miles (130 km) from the center of Raymond’s circulation.

Tropical Storm Raymond will move through an environment that will be only marginally favorable for intensification during the next 24 hours.  Raymond will move over water where the Sea Surface Temperatures are near 28°C.  It will move under the southwestern part of an upper level ridge that is over Mexico.  The upper level ridge will produce easterly winds that will blow toward the top of Raymond’s circulation.  Those winds will cause strong vertical wind shear.  The strong wind shear will inhibit intensification. Tropical Storm Raymond is likely to weaken on Saturday because of the strong vertical wind shear.

Tropical Storm Raymond will move around the western side of a high pressure system that is over Mexico.  The high pressure system will steer Raymond toward the northwest during the next 24 hours.  On its anticipated track, Tropical Storm Raymond will reach the southern end of Baja California on Saturday.

Tropical Storm Raymond will bring gust winds and locally heavy rain to the southern part of Baja California.  Heavy rain could cause flash floods in some locations.

Elsewhere over the Eastern North Pacific Ocean, former Tropical Storm Priscilla weakened west of Baja California.  At 5:00 p.m. EDT on Friday the center of Tropical Depression Priscilla was located at latitude 26.3°N and longitude 115.4°W which put the center about 220 miles (355 km) west-northwest of Cabo San Lazaro, Mexico.  Priscilla was moving toward the north at 6 m.p.h. (10 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 1004 mb.

Tropical Storm Raymond Forms South of Mexico

Tropical Storm Raymond formed over the Eastern North Pacific Ocean south of Mexico on Thursday.  At 2:00 p.m. EDT on Thursday the center of Tropical Storm Raymond was located at latitude 16.1°N and longitude 101.0°W which put the center about 115 miles (185 km) south-southeast of Zihuatanejo, Mexico.  Raymond was moving toward the northwest 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 1002 mb.

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

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

The distribution of thunderstorms in Tropical Storm Raymond was asymmetrical.  Thunderstorms were occurring in bands in the southern and western parts of Raymond’s circulation.  Bands in the northern and eastern parts of Tropical Storm Raymond consisted primarily of shower and lower clouds.  Storms near the center of Raymond started to generate upper level divergence that pumped mass away to the west of the tropical storm.

Tropical Storm Raymond will move through an environment that will be somewhat favorable for intensification during the next 24 hours.  Raymond will move over water where the Sea Surface Temperatures are near 29°C.  It will move under the southern part of an upper level ridge that is over Mexico.  The upper level ridge will produce easterly winds that will blow toward the top of Raymond’s circulation.  Those winds will cause strong vertical wind shear.  The strong wind shear will inhibit intensification.  Tropical Storm Raymond could intensify a little on Friday if the upper level winds do not get any stronger.

Tropical Storm Raymond will move around the western side of a high pressure system that is over Mexico.  The high pressure system will steer Raymond toward the northwest during the next 24 hours.  On its anticipated track, the center of Tropical Storm Raymond will move near the coast of Mexico between Zihuatanejo and Cabo Corrientes on Friday.

Tropical Storm Raymond will bring gusty winds and locally heavy rain to coastal sections of Colima, Michoacan, and western Guerrero.

Elsewhere over the Eastern North Pacific Ocean, Tropical Storm Priscilla continued to weaken west of Baja California.  At 11:00 a.m. EDT on Thursday the center of Tropical Storm Priscilla was located at latitude 23.8°N and longitude 114.7°W which put the center about 165 miles (265 km) west-southwest of Cabo San Lazaro, Mexico.  Priscilla was moving toward the north-northwest at 8 m.p.h. (13 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 996 mb.

Priscilla Weakens to a Tropical Storm

Former Hurricane Priscilla weakened to a tropical storm over the Eastern North Pacific Ocean south of Baja California on Wednesday afternoon.  At 2:00 p.m. EDT on Wednesday the center of Tropical Storm Priscilla was located at latitude 21.7°N and longitude 112.7°W which put the center about 195 miles (310 km) west-southwest of the southern tip of Baja California.  Priscilla was moving toward the northwest at 7 m.p.h. (11 km/h).  The maximum sustained wind speed was 70 m.p.h. (110 km/h) and there were wind gusts to 85 m.p.h. (135 km/h).  The minimum surface pressure was 985 mb.

A Tropical Storm Watch was in effect for the portion of the coast from Cabo San Lucas to Cabo San Lazaro, Mexico.

Former Hurricane Priscilla rapidly weakened to a tropical storm south of Baja California on Wednesday.  Thunderstorms around the center of Priscilla’s circulation and in the northern half of the circulation weakened.  Bands in those parts of Tropical Storm Priscilla consisted primarily of showers and lower clouds.  Thunderstorms were still occurring in bands in the southern and western periphery of Priscilla’s circulation.  Weakening of the thunderstorms near the core of Tropical Storm Priscilla greatly reduced the upper level divergence.  With much less upper level divergence the inflow of mass in the lower levels of the atmosphere caused the surface pressure to increase.

The circulation around Tropical Storm Priscilla was still large.  Winds to tropical storm force extended out 160 miles (260 km) from the center of Priscilla’s circulation.

Tropical Storm Priscilla will move through an environment that will become even more unfavorable for intensification during the next 24 hours.  Priscilla will move over water where the Sea Surface Temperatures are near 26°C.  An upper level trough near the west coast of the U.S. will produce southwesterly winds that will blow toward the top of Priscilla’s circulation.  Those winds will cause the vertical wind shear to increase.  The effects of cooler water and increasing vertical wind shear will cause Tropical Storm Priscilla to continue to weaken during the next 24 hours.

Tropical Storm Priscilla will move around the western end of a high pressure system over Mexico.  The high pressure system will steer Priscilla toward the north-northwest during the next 24 hours.  On its anticipated track, Tropical Storm Priscilla will move west of Cabo San Lazaro on Thursday.

Elsewhere over the Eastern North Pacific Ocean, Tropical Storm Octave continued to gradually weaken far to the southwest of Baja California.  At 11:00 a.m. EDT on Wednesday the center of Tropical Storm Octave was located at latitude 15.4°N and longitude 116.2.°W which put the center about 660 miles (1065 km) southwest of the southern tip of Baja California.  Octave was moving toward the east at 12 m.p.h. (19 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 1003 mb.
