Andres Weakens to a Tropical Depression

Former Tropical Storm Andres weakened to a tropical depression on Monday afternoon. At 5:00 p.m. EDT on Monday the center of Tropical Depression Andres was located at latitude 16.0°N and longitude 109.8°W which put it about 475 miles (765 km) south of the southern tip of Baja California. Andres was moving toward the north-northwest at 7 m.p.h. (11 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 1006 mb.

Strong vertical wind shear caused former Tropical Storm Andres to weaken to a tropical depression on Monday afternoon. An upper level trough northwest of Baja California was producing strong southwesterly winds which were blowing across the top of Tropical Depression Andres. Those winds were causing strong vertical wind shear and they were blowing the tops off of thunderstorms that tried to form. A few thunderstorms developed east of the center of Andres earlier on Monday, but the strong upper level winds blew the tops off of those storms. The circulation around Tropical Depression Andres consisted primarily of showers and lower clouds on Monday afternoon.

Tropical Depression Andres will move through an environment unfavorable for intensification during the next several days. Andres will move over water where the Sea Surface Temperatures will be near 26°C. However, the upper level trough northwest of Baja California will continue to produce strong upper level winds over Tropical Depression Andres. The strong upper level winds will blow the tops off any thunderstorms that begin to form and the circulation around Andres will gradually weaken.

Since the circulation around Tropical Depression Andres exists primarily in the lower levels, it will be steered by the wind closer to the surface. A large surface high pressure system over the Eastern North Pacific Ocean will steer Andres toward the west during the next several days. On its anticipated track Tropical Depression Andres will dissipate southwest of Baja California later this week.

TD 01E Strengthens to Tropical Storm Andres

Former Tropical Depression One-E strengthened to Tropical Storm Andres southwest of Mexico on Sunday morning. At 11:00 a.m. EDT on Sunday the center of Tropical Storm Andres was located at latitude 14.1°N and longitude 107.9°W which put it about 620 miles (1000 km) south-southeast of the southern tip of Baja California. Andres 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 1005 mb.

The circulation around former Tropical Depression One-E strengthened on Sunday morning and the National Hurricane Center designated the system as Tropical Storm Andres. The circulation around Andres was exhibiting more organization. Storms near the center of the circulation generated upper level divergence that pumped mass away from the tropical storm. Bands of showers and thunderstorms were revolving around the center of Andres. The strongest rainbands were in the eastern half of the circulation. Winds to tropical storm force extended out 70 miles (110 km) in the northeastern quadrant of Tropical Storm Andres. The winds in the other parts of the circulation were blowing at less than tropical storm force.

Tropical Storm Andres will move through an environment favorable for intensification during the next 24 hours. Andres will move over water where the Sea Surface Temperatures will be near 28°C. It will move under the center of an upper level ridge southwest of Mexico. The winds are weak near the center of the ridge and there will be little vertical wind shear. Tropical Storm Andres could strengthen during the next 24 hours. An upper level trough over the Eastern North Pacific Ocean will approach Andres from the west on Monday. The trough will produce southwesterly winds which will blow toward the top of the tropical storm. Those winds will cause the vertical wind shear to increase. More wind shear will cause Tropical Storm Andres to weaken early next week.

Tropical Storm Andres will move around the southwestern part of a subtropical high pressure system over the Gulf of Mexico and Mexico. The high will steer Andres toward the northwest on Sunday. Tropical Storm Andres will move southeast of a large high pressure system over the Eastern North Pacific Ocean during the early part of next week. That high pressure system will steer Andres toward the west. On its anticipated track Tropical Storm Andres will remain south of Baja California.

Tropical Depression One-E Forms Southwest of Mexico

Tropical Depression One-E formed southwest of Mexico on Sunday morning. At 5:00 a.m. EDT on Sunday the center of Tropical Depression One-E was located at latitude 13.8°N and longitude 107.7°W which put it about 645 miles (1035 km) south-southeast of the southern tip of Baja California. The depression was moving toward the northwest at 5 m.p.h. (8 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 1006 mb.

More thunderstorms developed near the center of a low pressure system formerly called Invest 90E on Sunday morning and the National Hurricane Center designated the system as Tropical Depression One-E. The circulation around the depression was exhibiting more organization. Storms near the center of the depression began to generate more upper level divergence which pumped mass away from it. Bands of showers and thunderstorms were revolving around the center.

Tropical Depression One-E will move through an environment favorable for develop of a tropical cyclone during the next 24 hours. It will move over water where the Sea Surface Temperatures will be near 29°C. The tropical depression will move under the center of an upper level ridge southwest of Mexico. The winds are weak near the center of the ridge and there will be little vertical wind shear. Tropical Depression One-E is likely to strengthen to a tropical storm during the next 24 hours. An upper level trough over the Eastern North Pacific Ocean will approach the depression from the west on Monday. The trough will produce southwesterly winds which will blow toward the top of the circulation. Those winds will cause the vertical wind shear to increase. More wind shear will cause the depression to weaken early next week.

Tropical Depression One-E will move around the southwestern part of a subtropical high pressure system over the Gulf of Mexico and Mexico. The high will steer the tropical depression toward the northwest on Sunday. Tropical Depression One-E will move southeast of a large high pressure system over the Eastern North Pacific Ocean during the early part of next week. That high pressure system will steer the tropical depression toward the west. On its anticipated track Tropical Depression One-E will remain south of Baja California.

Tropical Development Possible Southwest of Mexico

Development of a tropical cyclone southwest of Mexico is possible during the next few days. At 2:00 p.m. EDT on Friday the center of Invest 90E was located at latitude 11.2°N and longitude 102.5°W which put it about 415 miles (670 km) south-southwest of Acapulco, Mexico. The Invest was moving toward the west at 7 m.p.h. (11 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.

An area of low pressure, currently designated as Invest 90E, exhibited more organization on Friday afternoon. The National Hurricane Center (NHC) issued a Special Tropical Weather Outlook for the low pressure system. NHC indicated that there was a 40% probability that the system would develop into a tropical depression or a tropical storm during the next 48 hours and a 60% chance that development would occur during the next five days.

More thunderstorms developed near the center of Invest 90E. Bands of showers and thunderstorms also developed and the bands began to revolve around the center of the low pressure system. Storms near the center began to generate upper level divergence that pumped mass away from the system.

Invest 90E will move through an environment favorable for develop of a tropical cyclone during the next 36 hours. It will move over water where the Sea Surface Temperatures will be near 29°C. The low pressure system will move under the center of an upper level ridge southwest of Mexico. The winds are weak near the center of the ridge and there will be little vertical wind shear. Invest 90E is likely to develop into a tropical depression and it could quickly intensify into a tropical storm.

Invest 90E will move southeast of a large high pressure system over the Eastern North Pacific Ocean. The high pressure system will steer the Invest slowly toward the west-northwest. On its anticipated track the low pressure system will remain southwest of Mexico during the weekend.

Tropical Storm Polo Forms Southwest of Baja California

Tropical Storm Polo formed southwest of Baja California formed southwest of Baja California on Wednesday morning. At 10:00 a.m. EST on Wednesday the center of Hurricane Iota was located at latitude 13.8°N and longitude 116.0°W which put it about 605 miles (970 km) southwest of the southern tip of Baja California. Polo was moving toward the west-northwest at 12 m.p.h. (19 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.

More thunderstorms developed near the center of a low pressure system southwest of Baja California on Wednesday morning and the National Hurricane Center designated the system as Tropical Storm Polo. The circulation around Tropical Storm Polo was small. Winds to tropical storm force extended out 35 miles (55 km) from the center of circulation. The strongest thunderstorms were occurring in a band that wrapped around the eastern and southern sides of the center of Polo. Storms near the center generated upper level divergence which pumped mass away from the tropical storm.

Tropical Storm Polo will move through an environment favorable for intensification during the next 24 hours. Polo will move over water where the Sea Surface Temperature is near 27.5°C. It will move through a region where the upper level winds are weak during the next 24 hours and there will be little vertical wind shear. Tropical Storm Polo could intensify more on Wednesday. Polo will move closer to an upper level trough over the Eastern North Pacific Ocean on Thursday. The trough will produce southwesterly winds which will blow toward the top of Tropical Storm Polo. Those winds will cause moderate vertical wind shear and the shear will cause Polo to start to weaken later this week.

Tropical Storm Polo will move south of an high pressure system over the Eastern North Pacific Ocean. The high will steer Polo toward the west during the next several days. On its anticipated track Tropical Storm Polo will move farther away from Mexico.

Elsewhere, Tropical Depression Iota was moving across El Salvador. At 10:00 a.m. EST on Wednesday the center of Tropical Depression Iota was located at latitude 13.8°N and longitude 89.5°W which put it about 20 miles (30 km) west-northwest of San Salvador, El Salvador. Iota was moving toward the west at 12 m.p.h. (19 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 1006 mb.

Tropical Storm Odalys Forms Southwest of Baja California

Tropical Storm Odalys formed southwest of Baja California on Tuesday afternoon. At 4:00 p.m. EST on Tuesday the center of Tropical Storm Odalys was located at latitude 14.1°N and longitude 116.1°W which put it about 730 miles (1175 km) southwest of the southern tip of Baja California. Odalys was moving toward the west-northwest at 13 m.p.h. (20 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.

The circulation around an area of low pressure southwest of Baja California exhibited more organization on satellite images and the National Hurricane Center designated the system as Tropical Storm Odalys. The circulation around Odalys was still organizing on Tuesday afternoon. There were a few thunderstorms around the broad center of circulation. A band of showers and thunderstorms wrapped around the western side of the circulation and a second band of showers and thunderstorms wrapped around the eastern side of Tropical Storm Odalys. Winds to tropical storm force extended out 100 miles (160 km) in the eastern half of Odalys. Winds int he western half of the circulation were blowing at less than tropical storm force.

Tropical Storm Odalys will move through an environment somewhat favorable for intensification during the next 24 hours. Odalys will move over water where the Sea Surface Temperature is near 28°C. An upper level trough over the Eastern North Pacific Ocean will produce southwesterly winds which will blow toward the top of the circulation. Those winds will cause moderate vertical wind shear and they will limit intensification. Tropical Storm Odalys could strengthen during the next 24 hours. The trough will move closer to Odalys on Thursday and the wind shear will increase. Stronger vertical wind shear will cause Tropical Storm Odalys to weaken later this week.

Tropical Storm Odalys will move around the southwestern part of a ridge of high pressure centered over northern Mexico. The ridge will steer Odalys toward the west-northwest during the next several days hours. On its anticipated path Tropical Storm Odalys will move farther away from Baja California.

Zeta Brings Hurricane Force Winds to Yucatan, Warnings Issued for Gulf Coast

Zeta brought hurricane force winds to part of the Yucatan Peninsula early on Tuesday and warnings were issued for the Gulf Coast. At 5:00 a.m. EDT on Tuesday the center of Tropical Storm Zeta was located at latitude 21.0°N and longitude 88.4°W which put it about 85 miles (135 km) east-southeast of Progreso, Mexico. Zeta was moving toward the northwest at 14 m.p.h. (22 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 984 mb.

A Hurricane Warning was issued for the portion of the coast from Morgan City, Louisiana to the Mississippi/Alabama border. THe Hurricane Warning includes New Orleans, Lake Pontchartrain and Lake Maurepas. A Tropical Storm Warning was issued for the portion of the coast from the Mississippi/Alabama border to the Okaloosa/Walton County Line, Florida. The Hurricane Warning for the coast of Mexico from Punta Allen to Progreso was changed to a Tropical Storm Warning. A Tropical Storm Watch was in effect for the portion of the coast from Intracoastal City to Morgan City, Louisiana.

Hurricane Zeta made landfall on the northeastern part of the Yucatan Penisula just north of Tulum, Mexico on Monday night. Weather stations in Playa del Carmen and on Cozumel reported sustained wind speeds of hurricane force. Zeta dropped heavy rain over parts of the northern Yucatan Peninsula. The heavy rain could cause flash floods in some locations.

Zeta weakened to a tropical storm when it moved across the northern Yucatan. The center of Tropical Storm Zeta was just about to emerge over the southern Gulf of Mexico on Tuesday morning. The circulation around Zeta remained intact. Thunderstorms were occurring around the center of circulation. Bands of showers and thunderstorms were revolving around the core of Tropical Storm Zeta. Storms near the core generated upper level divergence which pumped mass away from the tropical storm. Wins to tropical storm force extended out 140 miles (220 km) from the center of Zeta.

Tropical Storm Zeta will move over the southern Gulf of Mexico during the next few hours. Zeta will move over water where the Sea Surface Temperature is near 29°C when it reaches the Gulf.  It will be under the western part of an upper level ridge where the upper level winds are weak and there will be little vertical wind shear.  Tropical Storm Zeta is likely to intensify back into a hurricane on Tuesday. An upper level trough over the southwestern U.S. will produce southwesterly winds which will blow toward the top of Hurricane Zeta on Wednesday. Those winds will cause more vertical wind shear and Zeta could weaken when it moves over the northern Gulf of Mexico.

Tropical Storm Zeta will move around the western end of a ridge of high pressure. The ridge will steer Zeta toward the northwest on Tuesday. Zeta will move more toward the north on Wednesday when it moves around the western end of the ridge. The upper level trough is likely to steer Zeta toward the northeast as it approaches the Gulf Coast. Zeta could approach the coast of southeast Louisiana on Wednesday afternoon. Zeta is likely to still be a hurricane when it approaches the Gulf Coast

Zeta Intensifies to a Hurricane, Watches Issued for Gulf Coast

Former Tropical Storm Zeta intensified into a hurricane over the northwestern Caribbean Sea on Monday. At 5:00 p.m. EDT on Monday the center of Hurricane Zeta was located at latitude 19.5°N and longitude 86.0°W which put it about 90 miles (145 km) southeast of Cozumel, Mexico. Zeta was moving toward the northwest at 10 m.p.h. (16 km/h). The maximum sustained wind speed was 80 m.p.h. (130 km/h) and there were wind gusts to 100 m.p.h. (160 km/h). The minimum surface pressure was 981 mb.

A Hurricane Warning was in effect for the portion of the coast from Tulum to Dzilam, Mexico and the warning included Cancun and Cozumel. A Hurricane Watch was issued for the portion of the coast from Morgan City, Louisiana to the Mississippi/Alabama border. The Hurricane Watch included New Orleans, Lake Pontchartrain and Lake Maurepas. Tropical Storm Warnings were in effect for the portions of the coast from Punta Allen to Tulum, Mexico and from Dzilam to Progresso. Tropical Storm Watches were issued for the portions of the coast from Intracoastal City to Morgan City, Louisiana and from the Mississippi/Alabama border to Okaloosa/Walton County Line, Florida.

Former Tropical Storm Zeta intensified quickly into a hurricane on Monday. More thunderstorms formed near the center of circulation and the circulation became more symmetrical. Storms that formed near the center of Hurricane Zeta generated upper level divergence which pumped mass away from the hurricane. The removal of mass allowed the surface pressure to decrease, which contributed to the increase in wind speed. Winds to hurricane force extended out 25 miles (40 km) from the center in the northeast quadrant of Zeta. The winds in the other quadrants were blowing at less than hurricane force. Winds to tropical storm force extended out 120 miles (195 km) in the eastern half of Hurricane Zeta. Winds to tropical storm force extended out 80 miles (130 km) in the western half of Zeta.

Hurricane Zeta will move through an environment favorable for intensification during the next few hours and it could strengthen more. Zeta will move across the Yucatan Peninsula on Monday night. It will likely weaken while the center passes over land. Hurricane Zeta will move over the southern Gulf of Mexico on Tuesday. Zeta will move over water where the Sea Surface Temperature is near 29°C when it reaches the Gulf.  It will be under the western part of an upper level ridge where the upper level winds are weak and there will be little vertical wind shear.  Hurricane Zeta is likely to intensify on Tuesday. An upper level trough over the southwestern U.S. will produce southwesterly winds which will blow toward the top of Hurricane Zeta. Those winds will cause more vertical wind shear and Zeta could weaken when it moves over the northern Gulf of Mexico.

Hurricane Zeta will move around the western end of a ridge of high pressure. The ridge will steer Zeta toward the northwest on Monday and Tuesday. On its anticipated track Hurricane Zeta will pass over the northeastern tip of Yucatan Peninsula on Monday night. Zeta will bring gusty winds and locally heavy rain to the northeastern Yucatan. It will also cause a storm surge of 4 to 7 feet (1 to 2 meters) along the coast where the wind blows the water toward the shore. Hurricane Zeta will move more toward the north on Wednesday when it moves around the western end of the ridge. Zeta could approach the coast of southeast Louisiana on Wednesday afternoon. Zeta is likely to still be a hurricane when it approaches the Gulf Coast

Tropical Storm Zeta Strengthens over Northwest Caribbean

Tropical Storm Zeta strengthened over the northwestern Caribbean Sea on Sunday. At 11:00 p.m. EDT on Sunday the center of Tropical Storm Zeta was located at latitude 18.1°N and longitude 83.8°W which put it about 260 miles (425 km) southeast of Cozumel, Mexico. Zeta was moving toward the north-northwest at 2 m.p.h. (3 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 997 mb.

The government of Mexico issued a Hurricane Warning for the coast of the Yucatan Peninsula from Tulum to Rio Lagartos and for Cozumel. The Hurricane Warning included Cancun. A Tropical Storm Warning was in effect for the Cuban province of Pinar del Rio.

The circulation around Tropical Storm Zeta strengthened during Sunday, but the distribution of thunderstorms was still asymmetrical. The stronger thunderstorms were mostly occurring in bands in the southern half of Zeta. Bands in the northern half of the circulation consisted primarily of showers and lower clouds. Despite the asymmetrical structure, thunderstorms near that center of circulation generated upper level divergence which pumped mass away from the tropical storm. The removal of mass allowed the surface pressure to decrease, which caused the wind speed to increase. Winds to tropical storm force extended out about 100 miles (160 km) from the center on the eastern side of Tropical Storm Zeta. The winds on the western side of Zeta were blowing at less than tropical storm force.

Tropical Storm Zeta will move through an environment favorable for intensification during the next 24 hours.  Zeta will move over water where the Sea Surface Temperature is near 29°C.  It will be under an upper level ridge where the upper level winds are weak and there will be little vertical wind shear.  Tropical Storm Zeta will intensify during the next 24 hours and it could strengthen to a hurricane. Zeta could weaken if the center passes over the northeastern Yucatan Peninsula.

A ridge of high pressure will strengthen to the northeast of Tropical Storm Zeta on Monday. The ridge will steer Zeta toward the northwest on Monday and Tuesday. On its anticipated track Tropical Storm Zeta could pass near the northeastern tip of Yucatan Peninsula on Monday night. Zeta could be a hurricane when it reaches the Yucatan. Zeta will move more toward the north on Wednesday when it moves around the western end of the ridge. Zeta could reach the central coast of the Gulf of Mexico on Wednesday afternoon.

Elsewhere over the Atlantic Ocean, Tropical Storm Epsilon made a transition to a powerful extratropical cyclone east of Newfoundland. At 11:00 p.m. EDT on Sunday the center of Tropical Storm Epsilon was located at latitude 48.6°N and longitude 38.8°W which put it about 675 miles (1090 km) east-northeast of Cape Race, Newfoundland. Epsilon was moving toward the northeast at 46 m.p.h. (74 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 968 mb.

Tropical Depression 28 Forms over Northwest Caribbean Sea

Tropical Depression Twentyeight formed over the northwestern Caribbean Sea on Saturday afternoon. At 5:00 p.m. EDT on Saturday the center of Tropical Depression Twentyeight was located at latitude 18.7°N and longitude 83.0°W which put it about 255 miles (405 km) south-southeast of the western tip of Cuba. The depression was moving toward the north-northwest at 2 m.p.h. (3 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. (650 km/h). The minimum surface pressure was 1005 mb. The government of Cuba issued a Tropical Storm Watch for the province of Pinar del Rio.

Based on data from a NOAA ariplane and visible satelite images, the National Hurricane Center determined than an area of low pressure over the northwestern Caribbean possessed sufficient organization to be designated Tropical Depression Twentyeight. The circulation around the depression was still organizing on Saturday afternoon. More thunderstorms were forming near the center of circulation. Bands of showers and thunderstorms were also developing in other parts of the depression. Storms near the center began to generate upper level divergence which pumped mass away from the tropical depression.

Tropical Depression Twentyeight will move through an environment favorable for intensification during the next several days.  The depression will move over water where the Sea Surface Temperature is near 29°C.  It will be under an upper level ridge where the upper level winds are weak and there will be little vertical wind shear.  Tropical Depression Twentyeight could intensify into a tropical storm during the next 24 hours and it could strengthen to a hurricane early next week.

Tropical Depression Twentyeight will be in an area where the steering winds are weak during the next 12 to 24 hours. The depression could drift toward the northwest during that time. A ridge of high pressure will strengthen to the northeast of the depression later on Sunday. The ridge will steer the depression toward the west-northwest on Monday and Tuesday. On its anticipated track Tropical Depression Twentyeight could pass near the western end of Cuba on Monday.

Elsewhere over the Atlantic Ocean, Hurricane Epsilon was passing south of Newfoundland. At 5:00 p.m. EDT on Saturday the center of Hurricane Epsilon was located at latitude 39.4°N and longitude 58.2°W which put it about 565 miles (910 km) south-southwest of Cape Race, Newfoundland. Epsilon was moving toward the northeast at 22m.p.h. (35 km/h). The maximum sustained wind speed was 80 m.p.h. (130 km/h) and there were wind gusts to 95 m.p.h. (150 km/h). The minimum surface pressure was 958 mb.
