Tropical Storm Norbert Develops Southwest of Mexico

Tropical Storm Norbert developed southwest of Mexico on Tuesday morning.  At 5: 00 a.m. EDT on Tuesday the center of Tropical Storm Norbert was located at latitude 13.7°N and longitude 106.2°W which put it about 385 miles (625 km) south-southwest of Manzanillo, Mexico.  Norbert 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.

The wind speed increased around a low pressure system southwest of Mexico on Tuesday morning and the National Hurricane Center designated the system as Tropical Storm Norbert.  More thunderstorms formed near the center of Norbert.  Storms near the center of circulation started to generate upper level divergence which pumped mass away to the northeast of the tropical storm.  Bands of showers and thunderstorms were developing outside the center of Norbert.  The circulation around Tropical Storm Norbert was small.  Winds to tropical storm force extended out 25 miles from the center of circulation.

Tropical Storm Norbert will be in an environment that is somewhat favorable for intensification.  Norbert will move over water where the Sea Surface Temperature is near 29°C.  A large upper level trough extends from northern Mexico over the Eastern North Pacific Ocean.  The trough will produce southwesterly winds which will blow toward the top of Tropical Storm Norbert.  Those winds will cause vertical wind shear and the shear will inhibit intensification.  Tropical Storm Norbert could strengthen if the shear is not too strong.

Tropical Storm Norbert will be in a region where the steering currents are weak..  Norbert is not likely to move very much during the next several days.  If Tropical Storm Norbert remains in the same location for more than a day, its winds will mix cooler water to the surface.  That would limit the energy Norbert could extract from the ocean, and the tropical storm could weaken.

Elsewhere over the Eastern North Pacific, Tropical Storm Marie continued to churn west away from Baja California.  At 5:00 a.m. EDT on Tuesday the center of Tropical Storm Marie was located at latitude 21.7°W and longitude 134.3°W which put it about 1560 miles (2510 km) west of the southern tip of Baja California.  Marie 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 1003 mb.

Tropical Storm Elida Forms Southwest of Mexico

Tropical Storm Elida formed southwest of Mexico on Sunday morning.  At 11:00 a.m. EDT on Sunday the center of Tropical Storm Elida was located at latitude 16.4°N and longitude 105.4°W which put it about 195 miles (310 km) south-southwest of Manzanillo,, Mexico.  Elida was moving toward the west-northwest at 17 m.p.h. (28 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 1005 mb.

The circulation around former Tropical Depression Nine-E exhibited much more organization on Sunday morning and the National Hurricane Center designated the system as Tropical Storm Elida.  Microwave satellite imagery suggested than an eye could be forming at the center of Elida.  A band of thunderstorms wrapped around the eastern side of the center of circulation and the band could represent the beginning of an eyewall.  Other bands of showers and thunderstorms were revolving around the core of Elida.  Storms near the core were generating upper level divergence which was pumping mass away from the tropical storm.  Winds to tropical storm force extended out about 50 miles (80 km) from the center of circulation.

Tropical Storm Elida will move through an environment favorable for intensification during the next several days.  Elida will move over water where the Sea Surface Temperature is near 29°C.  It will move through a region where the upper level winds are weak and there will be little vertical wind shear.  Tropical storm Elida will continue to intensify and it could strengthen into a hurricane within 24 hours.  Elida could rapidly intensify if an eye and eyewall form and it could strengthen into a major hurricane within 48 to 72 hours.

Tropical Storm Elida will move south of a ridge that extends from northern Mexico over the Eastern North Pacific Ocean.  The ridge will steer Elida toward the west-northwest during the next few days.  On its anticipated track Tropical Storm Elida will pass south of Baja California.

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.

Tropical Storm Narda Brings Rain to Mexico

Tropical Storm Narda brought rain to parts of the west coast of Mexico on Sunday.  At 5:00 p.m. EDT on Sunday the center of Tropical Depression Narda was located at latitude 19.1°N and longitude 103.3°W which put it about 55 miles (90 km) east of Manzanillo, Mexico.  Narda was moving toward the northwest at 20 m.p.h. (32 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 1002 mb.

The center of former Tropical Storm Narda made landfall on the west coast of Mexico between Lazaro Cardenas and Manzanillo on Sunday.  Narda weakened to a tropical depression after the center moved over land.  Bands of showers and thunderstorms were dropping locally heavy rain along and just inland of the portion of the coast from Acapulco to Manzanillo, Mexico.  The rain could be heavy enough in some locations to cause flash floods.

Tropical Depression Narda is moving around the western side of a high pressure system over Mexico.  The high is steering Narda quickly toward the northwest.  Tropical Depression Narda will move along the west coast of Mexico during the next day or two.  The center of Narda could move back over the Eastern North Pacific Ocean near Cabo Corrientes.  Tropical Depression Narda will continue to drop heavy rain near the coast while it moves toward the northwest.

Lorena Strengthens to a Hurricane Near Manzanillo

Former Tropical Storm Lorena strengthened to a hurricane near Manzanillo, Mexico on Wednesday night.  At 11:00 p.m. EDY on Wednesday the center of Hurricane Lorena was located at latitude 18.7°N and longitude 104.7°W which put it 35 miles (55 km) southwest of Manzanillo, Mexico.  Lorena was moving toward the northwest at 12 m.p.h. (19 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 990 mb.

A Hurricane Warning was in effect for the portion of the coast from Punta San Telmo to Cabo Corrientes, Mexico.  A Tropical Storm Warning was in effect for the coast from Cabo Corrientes to Punta Mita, Mexico.

The circulation around Hurricane Lorena exhibited more organization on Wednesday night.  Some satellite images suggested that a small eye might be forming at the center of circulation.  Lorena was a small hurricane.  Winds to hurricane force extended out about 20 miles (30 km) from the center of circulation.  Winds to tropical storm force extended out about 90 miles (145 km) from the center.

Hurricane Lorena will move through an environment favorable for intensification during the next several days.  Lorena will move over water where the Sea Surface Temperature is near 29°C.  It will move through a region where the upper level winds are not too strong and there is not likely to be a lot of vertical wind shear.  However, the center of Hurricane Lorena will move very close to the coast of Mexico.  Small hurricanes often draw drier air over the land into their circulations when they move close to the west coast of Mexico.  If Hurricane Lorena draws in drier air, it will weaken even though the rest of the environment is favorable for intensification.  If the center of Lorena moves farther away from the coast, then the hurricane could strengthen.

Hurricane Lorena will move around the western side of a ridge over Mexico.  The ridge will steer Lorena toward the northwest during the next several days.  On its anticipated track, Hurricane Lorena will pass very close to the west coast of Mexico on Thursday.  Hurricane Lorena could drop locally heavy rain and flash floods could occur.  If Hurricane Lorena doesn’t weaken near the coast, it could approach the southern tip of Baja California on Friday.

Elsewhere over the Eastern North Pacific Ocean, Tropical Storms Kiko and Mario strengthened on Wednesday.  At 11:00 p.m. EDT on Wednesday the center of Tropical Storm Kiko was located at latitude 15.8°N and longitude 127.8°W which put it about 1265 miles (2035 km) west-southwest of the southern tip of Baja California.  Kiko was moving toward the west 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 998 mb.

At 11:00 p.m. EDT on Wednesday the center of Tropical Storm Mario was located at latitude 15.4°N and longitude 112.2°W which put it about 540 miles 9870 km) south-southwest of the southern tip of Baja California.  Mario was moving toward the northwest at 10 m.p.h. (16 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 998 mb.

Tropical Depression One-E Forms West of Mexico

Tropical Depression One-E formed west of Mexico on Tuesday afternoon.  More thunderstorms developed close to the center of a low pressure system over the Eastern North Pacific Ocean and the National Hurricane Center designated the system as Tropical Depression One-E.  At 5:00 p.m. EDT on Tuesday the center of Tropical Depression One-E was located at latitude 15.2°N and longitude 105.7°W which put it about 280 miles (450 km) south-southwest of Manzanillo, Mexico.  The depression was moving toward the west-northwest at 15 m.p.h. (24 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 1007 mb.

The circulation around Tropical Depression One-E exhibited greater organization on Tuesday afternoon.  Several short bands of showers and thunderstorms were developing near the center of circulation.  One band was north of the center, another was west of the center and a third band was south of the center of circulation.  Bands east of the center consisted primarily of showers and lower clouds.  Thunderstorms near the center of circulation were beginning to generate upper level divergence which was pumping mass away from the tropical depression.

Tropical Depression One-E will move through an environment favorable for intensification during the next day or two.  The depression will move over water where the Sea Surface Temperature is near 28°C.  It will move south of an upper level ridge over Mexico and the Eastern North Pacific Ocean.  The ridge will produce northeasterly winds which will blow toward the top of the circulation.  Those winds will cause some vertical wind shear which will slow the rate of intensification, but the shear will not be strong enough to prevent intensification.  Tropical Depression One-E is likely to intensify into a tropical storm during the next 24 to 36 hours.

A subtropical ridge north of Tropical Depression One-E will steer the depression toward the west-northwest.  On its anticipated track Tropical Depression One-E will move away from Mexico.  It is forecast to pass south of Baja California.

Tropical Storm Xavier Causes Warning for Coast of Mexico

Potential impacts of Tropical Storm Xavier caused the government of Mexico to issue a Tropical Storm Warning for a portion of the coast.  The Tropical Storm Warning was in effect from Punta San Telmo to Playa Perula, Mexico.  At 1:00 p.m. EST the center of Tropical Storm Xavier was located at latitude 17.8°N and longitude 105.4°W which put it about 110 miles (175 km) southwest of Manzanillo, Mexico.  Xavier was moving toward the north at 6 m.p.h. (10 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.

An upper level trough is producing strong southwesterly winds which are blowing toward the top of Tropical Storm Xavier.  Those winds are causing significant vertical wind shear and they blew the upper portion of Xavier northeast of the lower level circulation earlier on Sunday morning.  However, new thunderstorms formed around the center of circulation and in a rainband northeast of the center.  There are several bands of showers and thunderstorms west of the center of circulation.  The bands southeast of the center consist primarily of low clouds and showers.  The strongest winds are occurring in the northeast portion of Tropical Storm Xavier.  Winds to tropical storm force extend out about 80 miles (130 km) from the center of circulation.  Winds are blowing to tropical storm force near the coast of Mexico which is why the Tropical Storm Warning was issued.

The future intensity of Tropical Storm Xavier will be determined by the strength of the upper level winds.  Xavier will move over water where the Sea Surface Temperature is near 28°C.  So, there is plenty of energy in the upper ocean to support a tropical storm.  However, the upper level winds were almost strong enough to shear Xavier apart on Sunday morning.  If the upper level winds do not get any stronger, then Xavier could persist as a tropical storm for another day or two.  If the upper level winds do get stronger, which is the forecast of many numerical models, then Xavier will quickly weaken to a tropical depression.  The official forecast from the National Hurricane Center follows the second scenario and it weakens Xavier to a tropical depression by Monday night.

The upper level trough will also determine future track of Tropical Storm Xavier.  If the upper level winds allow Xavier to persist as a tropical storm, then the trough will steer Xavier north-northeast toward the coast of Mexico.  If the upper level winds blow the top of the circulation away from the lower level circulation, then the winds closer to the surface would turn the lower part of Xavier back toward the west.  The official forecast from the National Hurricane Center follows the second scenario.

Bands of showers and thunderstorms in the northeaster part of Tropical Storm Xavier are already dropping rain over the coastal regions of Colima and Jalisco.  Prolonged heavy rain could cause flash floods in some locations.  Winds could reach tropical storm force along the coast even if the center of Tropical Storm Xavier does not make landfall.  There could also be a minor storm surge where the wind blows water toward the coast.

Tropical Storm Xavier Forms Southwest of Manzanillo

Tropical Storm Xavier formed southwest of Manzanillo, Mexico on Friday night.  At 11:00 p.m. EDT on Friday the center of Tropical Storm Xavier was located at latitude 14.5°N and longitude 108.2°W which put it about 405 miles (650 km) southwest of Manzanillo, Mexico.  Xavier was moving toward the east-northeast 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.

A center of circulation developed in an area of thunderstorms southwest of Mexico on Friday.  When more thunderstorms developed closer to the center of circulation on Friday night, the National Hurricane Center designated the system as Tropical Storm Xavier.  The core of Tropical Storm Xavier was small.  The inner part of a band of showers and thunderstorms was wrapping around the center of circulation.  Storms near the core were generating upper level divergence.  Other short bands of showers and thunderstorms were revolving around the center of Tropical Storm Xavier.  Winds to tropical storm force extended out about 70 miles (110 km) from the center of circulation, but the strongest winds were occurring primarily in the southeastern quadrant of Xavier.

Tropical Storm Xavier will move through an environment somewhat favorable for intensification during the weekend.  Xavier will move over water where the Sea Surface Temperature is near 28°C.  So, there will be plenty of energy in the upper ocean to support intensification.  However, an upper level trough west of Xavier will produce strong southwesterly winds which will blow toward the top of the tropical storm.  Those winds will cause moderate vertical wind shear and they will inhibit upper level divergence to the west of Tropical Storm Xavier.  Xavier is likely to intensify on Saturday, but its small circulation means that it could weaken if the wind shear increases.

The upper level trough will also steer Tropical Storm Xavier in a north-northeasterly direction during the next day or two.  On its anticipated track the center of Tropical Storm Xavier could approach the west coast of Mexico by Sunday night.

Tropical Storm Tara Develops South of Manzanillo

Tropical Storm Tara developed south of Manzanillo, Mexico on Monday.  At 11:00 a.m. EDT on Monday the center of Tropical Storm Tara was located at latitude 17.6°N and longitude 104.4°W which put it about 95 miles (155 km) south of Manzanillo, Mexico.  Tara was moving toward the west-northwest at 2 m.p.h. (3 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 1001 mb.  A Tropical Storm Watch was in effect for the portion of the coast from Punta San Telmo to Cabo Corrientes, Mexico.

The circulation around Tropical Storm Tara is still organizing.  More thunderstorms are developing near the center of circulation.  Several bands of showers and thunderstorms are beginning to form around the center.  Storms near the center are starting to generate upper level divergence which is pumping mass away to the east of the tropical storm.  The circulation around  Tropical Storm Tara is small.  Winds to tropical storm force only extend out about 35 miles (55 km) from the center of circulation.

Tropical Storm Tara will be in an environment somewhat favorable for intensification.  Tara will move over water where the Sea Surface Temperature is near 29°C.  An upper level trough near Baja California will produce southwesterly winds which will blow toward the top of the circulation.  Those winds will cause some vertical wind shear which will inhibit intensification.  The wind shear will not stop intensification, but they will slow it.  Tropical Storm Tara will remain close to Mexico and there is a chance that drier air from land could enter the northern part of the circulation.  Tropical Storm Tara is forecast to strengthen gradually.  However, because the circulation around Tropical Storm Tara is small, it could intensify or weaken very quickly if the environmental conditions change.

Tropical Storm Tara will be in an area where the steering currents are weak for another day or two.  Tara is forecast to move slowly toward the west-northwest during the next 24 to 48 hours.  On its anticipated track Tropical Storm Tara will remain west of Mexico.  However, several forecast models predict that Tara will move more northward and make landfall west of Manzanillo.  The government of Mexico issued a Tropical Storm Watch for that portion of the coast in case Tara brings tropical storm force winds to the coast.

Tropical Storm Rosa Develops Southwest of Mexico

Tropical Storm Rosa developed southwest of Mexico on Tuesday morning.  At 11:00 a.m. EDT on Tuesday the center of Tropical Storm Rosa was located at latitude 14.7°N and longitude 108.0°W which put it about 385 miles (620 km) southwest of Manzanillo, Mexico.  Rosa 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.

A distinct center of circulation consolidated in an area of thunderstorms southwest of Mexico on Tuesday morning and the National Hurricane Center designated the system as Tropical Storm Rosa.  An inner rainband wrapped tightly around the center.  Several other bands of showers and thunderstorms were revolving around the core of Tropical Storm Rosa.  The circulation was symmetrical and rainbands were occurring in all parts of the tropical storm.  Storms near the core began to generate upper level divergence which was pumping mass away from Rosa.

Tropical Storm Rosa will move through an environment favorable for intensification during the next several days.  Rosa will move over water where the Sea Surface Temperature is near 29°C.  It will move through a region where the upper level winds are weak and there will be little vertical wind shear.  Tropical Storm Rosa could intensify into a hurricane by later on Wednesday.

Tropical Storm Rosa will move southwest of a middle level ridge over northern Mexico.  The ridge will steer Rosa in a general west-northwesterly direction during the next several days.  On its anticipated track Tropical Storm Rosa will move southwest of Baja California later this week.
