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.

Tropical Storm Priscilla Forms Southwest of Mexico

Tropical Storm Priscilla formed over the Eastern North Pacific Ocean southwest of Mexico on Saturday afternoon.  At 5:00 p.m. EDT on Saturday the center of Tropical Storm Priscilla was located at latitude 15.5°N and longitude 106.6°W which put the center about 285 miles (460 km) south-southwest of Manzanillo, Mexico.  Priscilla was moving toward the northwest at 7 m.p.h. (11 km/h).  The maximum sustained wind speed was 45 m.p.h. (75 km/h) and there were wind gusts to 60 m.p.h. (95 km/h).  The minimum surface pressure was 1002 mb.

A Tropical Storm Watch was issued for the portion of the coast from Punta San Telmo to Punta Mita, Mexico.

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

The circulation around Tropical Storm Priscilla was large.  More thunderstorms formed near the center of Priscilla’s circulation on Saturday afternoon.  Bands of showers and thunderstorms were revolving around the center of Tropical Storm Priscilla.  Storms near the center of Priscilla began to generate upper level divergence that pumped mass away from the tropical storm.

The strongest winds were occurring in the northern side of Tropical Storm Priscilla.  Winds to tropical storm force extended out 140 miles (225 km) in the northern part of Priscilla’s circulation.  The winds in the southern side of Tropical Storm Priscilla were blowing at less than tropical storm force.

Tropical Storm Priscilla will move through an environment favorable for intensification during the next 24 hours.  Priscilla will move over water where the Sea Surface Temperatures are near 28°C.   It will move under the middle of an upper level ridge over Mexico and 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 Priscilla will intensify during the next 24 hours.  Priscilla could strengthen to a hurricane by Monday.

Tropical Storm Priscilla will move around the western end of a high pressure system over Mexico.  The high pressure system will steer Priscilla slowly toward the north-northwest during the next 24 hours.  On its anticipated track, Tropical Storm Priscilla will move a little closer toward the west coast of Mexico.

Elsewhere over the Eastern North Pacific Ocean, Tropical Storm Octave continued to meander far to the south-southwest of Baja California.  At 5:00 p.m. EDT on Saturday the center of Tropical Storm Octave was located at latitude 14.9°N and longitude 123.9°W which put the center about 1065 miles (1720 km) south-southwest of the southern tip of Baja California.  Octave was moving toward the north-northwest at 6 m.p.h. (10 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 997 mb.

Tropical Storm Priscilla Develops Near West Coast of Mexico

Tropical Storm Priscilla developed near the west coast of Mexico on Sunday.  At 2:00 p.m. EDT on Sunday the center of Tropical Storm Priscilla was located at latitude 18.6°N and longitude 104.0°W which put it about 55 miles (90 km) southeast of Manzanillo, Mexico.  Priscilla was moving toward the north at 10 m.p.h. (16 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  1004 mb.

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

A distinct low level center of circulation formed within a cluster of thunderstorms near the west coast of Mexico on Sunday and the National Hurricane Center designated the system as Tropical Storm Priscilla.  Thunderstorms were forming near the center of circulation.  Bands of showers and thunderstorms were also developing and the bands were revolving around the center of Priscilla.  Storms near the center were generating upper level divergence which was pumping mass away to the north of the tropical storm.  The circulation around Priscilla was small.  Winds to tropical storm force extended out 35 miles (55 km) from the center of circulation.

Tropical Storm Priscilla will move through an environment favorable for intensification during the next few hours.  The center of Priscilla will be over water where the Sea Surface Temperature is near 29°C.  It will be in a region where the upper level winds are not too strong and there will not be a lot of vertical wind shear.  However, the center of Tropical Storm Priscilla will be very close to Mexico.  The circulation around Priscilla will begin to pull drier air from over the land into the tropical storm.  Tropical Storm Priscilla could strengthen during the next few hours, but it is likely to weaken quickly when the center moves over Mexico.

Tropical Storm Priscilla will move around the western end of a high pressure system over Mexico.  The high will steer Priscilla on a track that will be a little to the west of straight north.  On its anticipated track, the center of Tropical Storm Priscilla will make landfall on the west coast of Mexico between Tecoman and Manzanillo within a few hours.  Priscilla could drop locally heavy rain which could cause flash floods in some places.
