Tropical Depression Fourteen Forms Over Western Caribbean

Tropical Depression Fourteen formed over the western Caribbean Sea on Thursday morning.  At 11:00 a.m. EDT on Thursday the center of Tropical Depression Fourteen was located at latitude 15.1°N and longitude 79.7°W which put it about 235 miles (375 km) east of Cabo Gracias a Dios.  The depression was moving toward the west at 21 m.p.h. (33 km/h).  The maximum sustained wind speed was 35 m.p.h. (55km/h) and there were wind gusts to 45 m.p.h. (75 km/h).  The minimum surface pressure was 1007 mb.

A Tropical Storm Watch was issued for the portion of the coast of Honduras from the border with Nicaragua to Punta Castilla including the Bay Islands.

Satellite images on Thursday morning indicated that a center of circulation had developed within a tropical wave over the western Caribbean Sea and the National Hurricane Center designated the system as Tropical Depression Fourteen.  The circulation around Tropical Depression Fourteen was still organizing.  Bands of showers and thunderstorms were developing and they were beginning to revolve around the center of circulation.  Storms near the center started to generate upper level divergence which was pumping mass away from the depression.

Tropical Depression Fourteen will move through an environment favorable for intensification during the next 36 to 48 hours.  The depression 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 the will be little vertical wind shear.  Tropical Depression Fourteen will strengthen during the next day or two.

Tropical Depression Fourteen will move around the southwester part of a subtropical high pressure system over the North Atlantic Ocean.  The high will steer the depression toward the west-northwest during the next 24 hours.  The depression will turn toward the northwest on Friday when it gets closer to the western end of the high.  On its anticipated track Tropical Depression Fourteen will pass near the coast of Honduras on Friday.  It will approach the Yucatan Peninsula on Saturday.  The depression could drop heavy rain over eastern Honduras and flash floods will be possible.

Elsewhere over the Atlantic Ocean,, Tropical Depression Thirteen was speeding toward the northern Leeward Islands.  At 11:00 a.m. EDT on Thursday the center of Tropical Depression Thirteen was located at latitude 16.0°N and longitude 52.0°W which put it about 750 miles (1205 km) east-southeast of the northern Leeward Islands.  The depression was moving toward the west-northwest at 21 m.p.h. (33km/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 Watches were in effect for Saba and St. Eustatius, St. Maarten, St. Kitts, Nevis, Antigua, Barbuda and Anguilla.

Tropical Depression Two-E Forms Near Guatemala

Tropical Depression Two-E formed near the coast of Guatemala on Saturday.  At 8:00 p.m. EDT on Saturday the center of Tropical Depression Two-E was located at latitude 12.6°N and longitude 91.0°W which put it about 90 miles (145 km) south of Puerto San Jose, Guatemala.  The depression was moving toward the north-northeast at 4 m.p.h. (6 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 1005 mb.

Tropical Storm Warnings were in effect for the entire coasts of El Salvador and Guatemala.

A distinct center of circulation developed south of the coast of Guatemala on Saturday.  More thunderstorms formed near the center and the National Hurricane Center designated the system as Tropical Depression Two-E.  Thunderstorms continued to form near the center.  Bands of showers and thunderstorms were revolving around the center of the depression.  The depression was near the center of a much larger counterclockwise circulation that is sometimes called a Central American Gyre (CAG).

Tropical Depression Two-E will move through an environment favorable for intensification during the next few hours.  The depression will move over water where the Sea Surface Temperature is near 30°C.  It will move under an upper level ridge over Central America.  The upper level winds are weak and there will be little vertical wind shear.  Tropical Depression Two-E could strengthen during the next few hours and there is a chance it could intensify into a tropical storm.

Tropical Depression Two-E will move around the western end of a high pressure system.  The high will steer the depression toward the north-northeast.  On its anticipated track the center of Tropical Depression Two-E will make landfall on the coast of Guatemala on Sunday.  The depression could drop heavy rain over  Guatemala, El Salvador and western Honduras.  The heavy rain could cause flash floods.

Possible Tropical Development Near Yucatan Peninsula

A tropical cyclone could develop near the Yucatan peninsula during the next few days.  At 2:00 p.m. EDT on Friday the center of Invest 91L was located at latitude 16.0°N and longitude 84.3°W which put it about 400 miles (640 km) southeast of Cancun, Mexico.  It was moving toward the northwest at 6 m.p.h. (10 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.

A broad area of low pressure is over the western Caribbean Sea, Central America and the adjacent waters of the Eastern North Pacific Ocean.  Several smaller, mesoscale centers of rotation appear to be revolving around the larger low pressure system.  One of the mesoscale centers is over the Eastern North Pacific Ocean just west of the coast of Central America.  One or two other mesoscale centers appear to be over the western Caribbean Sea near Honduras.  The low level circulation is not currently well organized.  It is broad and diffuse.  Thunderstorms are clustered around the mesoscale centers, but large scale rainbands have not formed.

Westerly winds in the upper levels are are blowing over the top of the system.  Those winds are creating moderate vertical wind shear which is inhibiting the development of the low pressure system.  The upper level winds are forecast to weaken during the next few days and the wind shear will diminish.  The Sea Surface Temperature of the water in the northwestern Caribbean Sea and Gulf of Mexico is near 30°C.  The broad low pressure system could slowly organize during the next two to three days.  The National Hurricane Center is indicating that there is a 70% probability of formation of a tropical cyclone near the Yucatan peninsula or over the southern Gulf of Mexico during the next five days.  A reconnaissance plane is scheduled to investigate the low pressure system on Sunday, if necessary.

The broad low is southwest of a subtropical high pressure system over the Atlantic Ocean.  The high is expected to steer the low toward the northwest during the weekend.  On its anticipated track the low will move over the northwestern Caribbean Sea during the next several days.  it could move into the Gulf of Mexico on Monday.

Elsewhere over the Atlantic Ocean, Tropical Storm Leslie continued to meander northeast of Bermuda.  At 11:00 a.m. EDT on Friday the center of Tropical Storm Leslie was located at latitude 36.2°N and longitude 58.4°W which put it about 455 miles (730 km) northeast of Bermuda.  Leslie was moving toward the north-northwest at 9 m.p.h. (15 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 986 mb.

Tropical Storm Selma Makes Landfall in El Salvador

Tropical Storm Selma made landfall in El Salvador on Saturday morning.  Selma weakened to a tropical depression after it moved inland.  At 11:00 a.m. EDT on Saturday the center of Tropical Depression Selma was located at latitude 13.7°N and longitude 88.5°W which put it about 45 miles (75 km) east of San Salvador, El Salvador.  Selma was moving toward the northeast at 8 m.p.h. (13 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.

The coastal warnings and watches for El Salvador and Honduras have been discontinued.

Tropical Depression Selma will continue to weaken as it moves farther inland.  The higher mountains will disrupt the circulation in the lower levels, but the circulation in the middle and upper levels could persist longer.  Tropical Depression Selma will drop locally heavy rain over El Salvador, western Honduras and eastern Guatemala.  The heavy rain could produce flash floods and mudslides.

Potential Tropical Cyclone Eighteen Prompts Warnings for Cuba and Bahamas

Potential Tropical Cyclone Eighteen prompted the governments of Cuba and the Bahamas to issue Tropical Storm Warnings and Watches for portions of those countries on Friday afternoon.  At 5:00 p.m. EDT on Friday the center of Potential Tropical Cyclone Eighteen was located at latitude 17.5°N and longitude 84.5°W which put it about 415 miles (670 km) south-southwest of Havana, Cuba.  It was moving toward the north-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 1006 mb.

Tropical Storm Warnings were issued for the Cuban provinces of Isla de la Juventud, La Habana, Ciudad de la Habana, Matanzas, Cienfuegos, and Villa Clara.  Tropical Storm Warnings were also issued for the northwestern Bahamas including the Abacos, Andros Island, Berry Island, Bimini, Eleuthera, Grand Bahama Island and New Providence.  Tropical Storm Watches were issued for the Central Bahamas including Cat Island, the Exumas, Long Island, Rum Cay and San Salvador.

An Air Force Reserve Hurricane Hunter reconnaissance plane investigated the system formerly known as Invest 93L on Friday afternoon.  The plane found sustained winds to tropical storm force.  The plane also found a broad circulation center with several smaller centers of circulation revolving around inside the broader center.  Based on the observations from the plane, the National Hurricane Center (NHC) chose not to upgrade the system to Tropical Storm Philippe in its 5:00 p.m. EDT advisory.  However, NHC did change the designation of the system from Invest 93L to Potential Tropical Cyclone Eighteen.  If a more well defined center of circulation develops, then NHC could still change designation of the system to Tropical Storm Philippe.

The circulation of Potential Tropical Cyclone Eighteen is still organizing.  As mentioned above, there is a broad center of counterclockwise rotation.  There are also several smaller counterclockwise swirls within the broader center.  More showers and thunderstorms developed closer to the center of circulation on Friday afternoon.  The storms closer to the center of circulation were generating some upper level divergence which was pumping away mass to the northeast of the system.  Some bands of showers and thunderstorms were developing in the outer portions of the circulation.

Potential Tropical Cyclone Eighteen will move through an environment somewhat favorable for intensification.  It will move over water where the Sea Surface Temperature is near 30°C.  The system is embedded in a flow over warm moist air.  However there is a stationary front northwest of the system and there is cooler, drier air north of the stationary front.  The system is currently under the western side of an upper level ridge.  The upper level winds are weak and there is not much vertical wind shear.  Potential Tropical Cyclone Eighteen could slowly intensify during the next 24 hours as the circulation becomes more well organized.

The ridge east of Potential Tropical Cyclone Eighteen is steering the system toward the north-northwest.  That general motion should continue for another six to twelve hours.  An upper level trough will approach the system from the west on Saturday and the trough will start to steer it more toward the northeast.  On its anticipated track Potential Tropical Cyclone Eighteen will approach Cuba on Saturday afternoon.  The center of the system will move south of the Florida Keys on Saturday night and it could move across the northwestern Bahamas on Sunday.

The system will bring gusty winds and locally heavy rain to those locations.  The locally heavy rain could cause flooding.  There could be a storm surge of several feet (one to two meters) on parts of the south coast of Cuba, where the wind blows the water toward the coast.  There could also be some storm surge along the coasts of the Florida Keys.

Tropical Storm Selma Forms South of El Salvador

Tropical Storm Selma formed south of El Salvador on Friday morning.  At 11:00 a.m. EDT on Friday the center of Tropical Storm Selma was located at latitude 11.1°N and longitude 89.5°W which put it about 180 miles (290 km) south of San Salvador, El Salvador.  Selma was moving toward the northwest 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 1005 mb.

A Tropical Storm Warning has been issued for the entire coast of El Salvador.  A Tropical Storm Watch has been issued for the entire Pacific Coast of Guatemala.

A distinct low level center of circulation formed in a larger area of thunderstorms south of El Salvador on Friday morning and the National Hurricane Center designated the system as Tropical Storm Selma.  The circulation of Tropical Storm Selma is very asymmetrical.  Most of the showers and thunderstorms are located in the western half of the circulation.  There are bands of showers in the eastern half of the circulation.  An upper level ridge centered over the Yucatan Peninsula is producing easterly winds which are blowing over the top of the circulation.  Those winds are causing moderate vertical wind shear which is the primary reason for the asymmetrical structure of the circulation.  Selma is a small tropical storm.  Winds to tropical storm force only extend out about 45 miles (75 km) from the center of circulation.

Tropical Storm Selma will be moving through an environment that is neutral for intensification.  Selma will move over water where the Sea Surface Temperature is near 29°C.  The upper level ridge will continue to cause moderate vertical wind shear.  The shear will inhibit further intensification.  If the upper level winds weaken, then some intensification may be possible.  However, if the upper level winds get stronger, then Selma could weaken to a tropical depression.

A large counterclockwise circulation centered over Nicaragua and Honduras is steering Tropical Storm Selma slowly toward the northwest and the general motion is expected to continue on Friday.  The upper level ridge over the Yucatan Peninsula will weaken on Saturday and that will allow Tropical Storm Selma to move more toward the north.  On its anticipated track Tropical Storm Selma will make landfall on the coast of El Salvador or Guatemala on Saturday.

Tropical Storm Selma will bring some gusty winds to the coast.  However, locally heavy rain and flash floods will be the primary risks associated with Tropical Storm Selma when it makes landfall.

Low Pressure Forms Near Northwest Caribbean Sea

An area of low pressure formed near the northwestern Caribbean Sea on Monday and the system has been designated as Invest 93L.  At 8:00 p.m. EDT on Monday the center of Invest 93L was located at latitude 14.0°N and longitude 83.0°W which put it about 75 miles (120 km) south-southeast of Cabo Gracias a Dios.  It was moving toward the north at 6 m.p.h. (9 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.

An area of low pressure formed in the southern portion of an area of showers and thunderstorms that has persisted over the western Caribbean Sea for several days.  The circulation of Invest 93L is not well organized.  There is no well organized center of circulation nor are there well organized rainbands.  Most of the showers and thunderstorms are occurring in the northern portion of the circulation.  There are not many showers or thunderstorms in the southern half of the circulation.  Much of the western half of the circulation is over Nicaragua and Honduras.

Invest 93L will move through an environment mostly favorable for the development of a tropical cyclone during the next few days.  It will move over water where the Sea Surface Temperature is near 30°C.  Invest 93L is near the axis of an upper level ridge.  So, the upper level winds are weak over the system.  There are stronger winds farther north over the northern Caribbean Sea.  Invest 93L will be slow to develop as long as almost half of the circulation is over land.  Development will be more likely when the center moves farther away from land.

Invest 93L is just west of the axis of the ridge, which is steering the system slowly toward the north.  That general motion is forecast to continue for several more days.  On its anticipated track Invest 93L will move over the northwestern Caribbean Sea later this week.  Invest 93L will drop locally heavy rain over Nicaragua and Honduras and it could cause flash floods in some areas.

Tropical Storm Nate Makes Landfall in Nicaragua

Tropical Depression Sixteen strengthened into Tropical Storm Nate and Nate made landfall on the coast of northeastern Nicaragua on Thursday morning.  At 2:00 p.m. EDT on Thursday the center of Tropical Storm Nate was located at latitude 14.5°N and longitude 84.0°W which put it about 50 miles (80 km) south-southwest of Puerto Lempira, Honduras.  Nate 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 1001 mb.

A Hurricane Watch was in effect for the portion of the coast from Punta Herrero to Rio Lagartos, Mexico.  A Tropical Storm Warning is also in effect from Punta Herrero to Rio Lagartos.  A Tropical Storm Warning is in effect for the portion of the coast from Sandy Bay Sirpi, Nicaragua to Punta Castilla, Honduras.

The center of Tropical Depression Sixteen strengthened on Thursday morning before it made landfall in Nicaragua and the National Hurricane Center designated the system as Tropical Storm Nate.  Showers and thunderstorms continue to develop near the center of circulation even though it is moving across northeastern Nicaragua.  The winds to tropical storm force are occurring in bands of showers and storms east of the center over the Caribbean Sea.  The winds are weaker in the portions of the circulation that are over land.

Tropical Storm Nate will not strengthen while the center is over land.  Nate will move into a favorable environment when it moves over the northwestern Caribbean Sea on Friday.  The Sea Surface Temperature will be near 30°C.  An upper level low will cause southerly winds to blow toward the top of the circulation, but the vertical wind shear is not likely to be strong enough to prevent intensification.  It could take a few hours for the inner core of the circulation to reorganize after it moves back over water.  Once the inner core reorganizes, then a period of rapid intensification could occur.  Nate could become a hurricane over the northwest Caribbean Sea or southern Gulf of Mexico.

An upper level low west of Florida will drift westward over the Gulf of Mexico.  The upper low and an upper level ridge east of Florida will combine to steer Tropical Storm Nate toward the north-northwest.  On its anticipated track Tropical Storm Nate will emerge over the northwestern Caribbean Sea on Friday.  Nate could be near the Yucatan peninsula on Friday night and it could move into the Gulf of Mexico on Saturday.  Nate could approach the northern Gulf Coast on Saturday night or Sunday morning.

Tropical Storm Nate is dropping heavy rain on parts of Nicaragua and Honduras.  There is the potential for flooding in those areas.  Nate is likely to be a hurricane when it approaches the Gulf Coast.  It will be capable of causing wind damage, a storm surge and locally heavy rain.

Tropical Depression 16 Organizes Near Nicaragua

Tropical Depression Sixteen organized near Nicaragua on Wednesday.  At 11:00 p.m. EDT on Wednesday the center of Tropical Depression Sixteen was located at latitude 12.8°N and longitude 82.7°W which put it about 95 miles (155 km) south-southeast of Puerto Cabezas, Nicaragua.  It was moving toward the northwest 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.

A Hurricane Watch was in effect for the portion of the coast from Punta Herrero to Cabo Catoche, Mexico.  A Tropical Storm Warning was in effect for the portion of the coast from Sandy Bay Sirpi, Nicaragua to Punta Castilla, Honduras.

The circulation of Tropical Depression Sixteen exhibited more organization on Wednesday.  An Air Force Reserve Hurricane Hunter reconnaissance aircraft found a distinct surface center of circulation on Wednesday afternoon.  More thunderstorms began to form near the center on Wednesday evening.  Bands of showers and thunderstorms developed on the northern and southern sides of the circulation.  There were sustained winds in some of the bands that were near tropical storm force.

Tropical Depression Sixteen will move through an environment that will be favorable for intensification during the next several days.  It will move over water where the Sea Surface Temperature is near 30°C.  The upper level winds will be weak and there will be little vertical wind shear.  Some of the western part of the circulation is passing over Nicaragua and the increased friction is the only factor inhibiting intensification.  If the center of circulation stays over water, then the depression will likely strengthen into a tropical storm on Thursday.  If the center of circulation moves over northeastern Nicaragua, then the depression will weaken.  The system is likely to strengthen when it moves over the northwestern Caribbean Sea on Friday.

A ridge of high pressure is steering the tropical depression slowly toward the northwest and that motion is expected to continue for another day or so.  An upper low near the west coast of Florida is going to move west across the Gulf of Mexico.  When the upper low gets northwest of Tropical Depression Sixteen, it will start to pull the depression more toward the north.  On its anticipated track the center of Tropical Depression Sixteen will move near or over northeastern Nicaragua on Thursday.  The depression could drop very heavy rain and cause floods in parts of Nicaragua and Honduras.  It is forecast to move over the northwestern Caribbean Sea on Friday and the depression could be near the northeastern Yucatan peninsula by Friday night.  The depression is expected to move into the Gulf of Mexico on Saturday.  There is more uncertainty about the future track of the system after that time.

Low Pressure Develops Over Southwest Caribbean Sea

An area of low pressure developed over the southwestern Caribbean Sea on Tuesday afternoon and the system was designated Invest 90L.  At 5:00 p.m. EDT on Tuesday the center of Invest 90L was located at latitude 12.0°N and longitude 80.7°W which put it about 200 miles (320 km) east of Bluefields, Nicaragua.  It was moving toward the west-northwest at 5 m.p.h. (8 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.

The circulation of Invest 90L was still organizing on Tuesday afternoon.  The area of low pressure appeared to have a distinct center of circulation.  Several bands of showers and thunderstorms were forming south and east of the center of circulation.  There were fewer showers and thunderstorms northwest of the center.  There was some upper level divergence that was pumping mass away to the south and west of the center.

Invest 90L will be moving through an environment favorable for intensification.  The Sea Surface Temperature in the southwest Caribbean Sea is near 30°C and the warm water is fairly deep.  The energy content of the water in that area is high.  An upper level ridge centered over the western Gulf of Mexico is producing northeasterly which are blowing toward the northwestern side of Invest 90L.  Those winds are producing some vertical wind shear, but the shear is not likely to be strong enough to prevent the formation of a tropical cyclone.  Invest 90L is likely to become a tropical depression or storm during the next 24 to 48 hours.  If the center remains east of Nicaragua, rapid intensification could occur after the circulation consolidates around the low level center.

Invest 90L is moving slowly toward the west-northwest as it moves near the southern side of a mid-level ridge.  That ridge could steer Invest 90L close to the coast of Nicaragua during the next several days.  The mid-level ridge is forecast to move east to near the Bahamas during the next 24 to 48 hours.  After that time, southerly winds are forecast to steer Invest 90L toward the north.  On its anticipated track the center of Invest 90L could move very close to Nicaragua during the next day or two.  It could bring locally heavy rain to Nicaragua and Honduras.  Invest 90L could move into the Gulf of Mexico in a few days.  The intensity of Invest 90L when it reaches the Gulf will depend on how much it interacts with Nicaragua and the Yucatan peninsula.  If the center stays over water, then it could be a hurricane when it reaches the Gulf of Mexico.  If the center spends more time over land, then the system will be weaker when it reaches the Gulf.  Some models are forecasting that a hurricane could make landfall on the northern Gulf Coast during the weekend.
