Hurricane Ernesto Speeds Toward Southeastern Newfoundland

Hurricane Ernesto sped to southeastern Newfoundland on Monday afternoon.  At 5:00 p.m. EDT on Monday the center of Hurricane Ernesto was located at latitude 43.6°N and longitude 56.1°W which put the center about 250 miles (400 km) southwest of Cape Race, Newfoundland.  Ernesto was moving toward the northeast at 26 m.p.h. (43 km/h).  The maximum sustained wind speed was 90 m.p.h. (145 km/h) and there were wind gusts to 105 m.p.h. (165 km/h).  The minimum surface pressure was 968 mb.

Hurricane Ernesto strengthened as it sped over the Gulf Stream toward southeastern Newfoundland on Monday afternoon.  A small circular eye was at the center of Ernesto’s circulation.  The eye was surrounded by a ring of thunderstorms and the strongest winds were occurring in that ring of storms.  Bands of showers and thunderstorms were revolving around the center of Ernesto’s circulation.  Storms near the center of circulation generated upper level divergence that pumped mass away to the east of the hurricane.

The circulation around Hurricane Ernesto was still exhibiting the characteristics of a tropical cyclone.  Winds to hurricane force extended out 45 miles (75 km) in the eastern side of Ernesto’s circulation.  Winds to tropical storm force extended out 220 miles (350 km) from the center of Hurricane Ernesto.

Hurricane Ernesto will move through an environment that will be unfavorable for intensification of a tropical cyclone during the next 24 hours.  Ernesto will move over water where the Sea Surface Temperatures are near 17°C.  It will move under the eastern portion of an upper level trough over the northeastern U.S.  The upper level trough will produce southwesterly winds that will blow toward the top of Ernesto’s circulation.  Those winds will cause strong vertical wind shear.  The colder water and strong wind shear will cause Hurricane Ernesto to weaken during the next 24 hours.  The colder water and vertical wind shear will also cause Hurricane Ernesto to make a transition to an extratropical cyclone.

The upper level trough over the northeastern U.S. will steer Hurricane Ernesto toward the east- northeast during the next 24 hours.  On its anticipated path, Ernesto will pass far to the south of pass near southeastern Newfoundland on Monday night.  Ernesto will move south of Greenland on Tuesday.

The circulation around the northern side of Hurricane Ernesto could bring gusty winds and locally heavy rain to southeastern Newfoundland.

Hurricane Ernesto Moves Toward Southeastern Newfoundland

Hurricane Ernesto moved toward southeastern Newfoundland on Sunday.  At 5:00 p.m. EDT on Sunday the center of Hurricane Ernesto was located at latitude 37.9°N and longitude 62.3°W which put the center about 815 miles (1310 km) southwest of Cape Race, Newfoundland.  Ernesto was moving toward the north-northeast at 17 m.p.h. (28 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 977 mb.

After briefly weakening to a tropical storm north of Bermuda on Saturday night, Ernesto strengthened back to a hurricane on Sunday.  The inner end of a rainband wrapped back around the center of Hurricane Ernesto.  A circular eye was visible again at the center of Ernesto’s circulation.  The eye was surrounded by a ring of thunderstorm and the strongest winds were occurring in that ring of storms.  Thunderstorms also developed in the rainbands revolving around the center of Hurricane Ernesto.  Storms near the center of Ernesto generated upper level divergence that pumped mass away to the northeast of the hurricane.

The size of the circulation around Hurricane Ernesto was a little smaller on Sunday.  Winds to hurricane force extended out 35 miles (55 km) in the southeastern quadrant of Ernesto’s circulation.  Winds to tropical storm force extended out 220 miles (355 km) from the center of Hurricane Ernesto.

Hurricane Ernesto will move through an environment that will be favorable for intensification during the next 24 hours.  Ernesto will move over water where the Sea Surface Temperatures are near 27°C.  It will move under the eastern portion of an upper level trough over the Great Lakes.  The upper level trough will produce southwesterly winds that will blow toward the top of Ernesto’s circulation.  Those winds will cause moderate vertical wind shear.  The wind shear will inhibit intensification, but the shear will not be enough to stop intensification.  Hurricane Ernesto is likely to strengthen during the next 24 hours.  Ernesto will move over colder water on Monday night.  The colder water and vertical wind shear will cause Hurricane Ernesto to make a transition to an extratropical cyclone.

The upper level trough over the Great Lakes will steer Hurricane Ernesto toward the northeast during the next 24 hours.  On its anticipated path, Ernesto will pass far to the south of Nova Scotia on Sunday night.  Hurricane Ernesto will be near southeastern Newfoundland on Monday night.

 

Tropical Storm Ernesto Moves Away from Bermuda

Tropical Storm Ernesto moved away from Bermuda on Saturday evening.  At 11:00 p.m. EDT on Saturday the center of Tropical Storm Ernesto was located at latitude 33.9°N and longitude 63.3°W which put the center about 140miles (220 km) northeast of Bermuda.  Ernesto was moving toward the north-northeast at 8 m.p.h. (13 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 978 mb.

A Tropical Storm Warning was in effect for Bermuda.

Former Hurricane Ernesto weakened to a tropical storm on Saturday evening.  Drier air wrapped all of the way around Ernesto’s circulation.  The drier air caused many of the remaining thunderstorms in Tropical Storm Ernesto to dissipate.  Thunderstorms were still occurring in the northern portion of the former eyewall.  The remnant of former Hurricane Ernesto’s large eye was also visible on satellite imagery.  The bands revolving around the center of Ernesto’s circulation consisted primarily of showers and lower clouds.

The circulation around Tropical Storm Ernesto was large.  Winds to tropical storm force extended out 230 miles (370 km) from the center of Ernesto’s circulation.

Tropical Storm Ernesto will move through an environment that will be somewhat favorable for intensification during the next 24 hours.  Ernesto will move over water where the Sea Surface Temperatures are near 28°C.  It will move under the southern portion of an upper level trough off the east coast of the U.S.  The upper level trough will produce southwesterly winds that will blow toward the top of Ernesto’s circulation.  Those winds will cause some vertical wind shear, but the wind shear will be less on Sunday.  The wind shear and the drier air In Ernesto’s circulation will inhibit intensification.  However, Tropical Storm Ernesto could strengthen a little during the next 24 hours even with the vertical wind shear and drier air.

Tropical Storm Ernesto will move around the western side of a subtropical high pressure system over the Atlantic Ocean.  The high pressure system will steer Ernesto toward the north-northeast during the next 24 hours.  An upper level trough over the Great Lakes will steer Ernesto toward the northeast more quickly on Monday.  Tropical Storm Ernesto could approach southeastern Newfoundland on Monday night.

Hurricane Ernesto Hits Bermuda

Hurricane Ernesto hit Bermuda early on Saturday.  At 8:00 a.m. EDT on Saturday the center of Hurricane Ernesto was located at latitude 32.6°N and longitude 64.6°W which put the center about 15 miles (25 km) north-northeast of Bermuda.    Ernesto was moving toward the north-northeast at 9 m.p.h. (15 km/h).   The maximum sustained wind speed was 85 m.p.h. (135 km/h) and there were wind gusts to 100 m.p.h. (160 km/h).   The minimum surface pressure was 974 mb.

A Hurricane Warning was in effect for Bermuda.

The center of Hurricane Ernesto passed over Bermuda early on Saturday.  A weather station at the L.F. Wade International airport reported a sustained wind speed of 61 m.p.h. (98 km/h) and a wind gust of 84 m.p.h. (135 km/h).  There were reports of widespread electricity outages in Bermuda.

The size of the circulation around Hurricane Ernesto was large when Ernesto moved over Bermuda.  Winds to hurricane force extended out 70 miles (110 km) from the center of Ernesto’s circulation.  Winds to tropical storm force extended out 240 miles (390 km) from the center of Hurricane Ernesto.

The Hurricane Intensity Index (HII) was 12.7.  The Hurricane Size Index (HSI) was 22.3 and the Hurricane Wind Intensity Size Index (HWISI) was 35.0.  Hurricane Ernesto was similar in intensity to Hurricane Irene when Irene hit North Carolina in 2011.  Ernesto was not quite as large as Irene was.

Drier air was pulled around the southern side of Hurricane Ernesto as it approached Bermuda.  The drier air caused many of the thunderstorms in the western and southern parts of Ernesto’s circulation to weaken.  Bands in the western and southern sides of Hurricane Ernesto consisted primarily of showers and lower clouds.  Thunderstorms were still occurring in bands in the eastern and northern parts of Ernesto.  Storms near the center of Ernesto’s circulation generated upper level divergence that pumped mass away to the northeast of the hurricane.

Hurricane Ernesto will move through an environment that will be somewhat favorable for intensification during the next 24 hours.  Ernesto will move over water where the Sea Surface Temperatures are near 29°C.  It will move under the southern portion of an upper level trough off the east coast of the U.S.  The upper level trough will produce southwesterly winds that will blow toward the top of Ernesto’s circulation.  Those winds will cause moderate vertical wind shear.  The drier air In Ernesto’s circulation will inhibit intensification.  Hurricane Ernesto is likely to maintain its intensity during the next 24 hours.

Hurricane Ernesto will move around the western side of a subtropical high pressure system over the Atlantic Ocean.  The high pressure system will steer Ernesto toward the north-northeast during the next 24 hours.  On its anticipated track, Hurricane Ernesto will move away from Bermuda on Saturday.  An upper level trough over the Great Lakes will steer Ernesto toward the northeast more quickly on Sunday.  Hurricane Ernesto could approach Newfoundland on Monday night.

The wind speeds will diminish in Bermuda as Hurricane Ernesto moves farther away on Saturday.

 

 

Hurricane Lee Prompts Watches for Northeast U.S.

The risk posed by Hurricane Lee prompted the issuance of a Hurricane Watch and a Tropical Storm Watch for a portion of the Northeast U.S. on Wednesday afternoon. At 5:00 p.m. EDT on Wednesday the center of Hurricane Lee was located at latitude 27.4°N and longitude 67.6°W which put it about 380 miles (610 km) south-southwest of Bermuda. Lee was moving toward the north-northwest at 9 m.p.h. (15 km/h). The maximum sustained wind speed was 105 m.p.h. (165 km/h) and there were wind gusts to 125 m.p.h. (200 km/h). The minimum surface pressure was 952 mb.

A Hurricane Watch was in effect for the portion of the coast from Stonington, Maine to the U.S./Canada border. A Tropical Storm Warning was in effect for Bermuda. A Tropical Storm Watch was in effect for the portion of the coast from Watch Hill, Rhode Island to Stonington, Maine. The Tropical Storm Watch included Block Island, Martha’s Vineyard and Nantucket.

Hurricane Lee weakened a little on Wednesday, but Lee remained a large and powerful hurricane. A circular eye with a diameter of 36 miles (50 km) was at the center of Lee’s circulation. The eye was surrounded by a broken ring of thunderstorms and the strongest winds were occurring in that ring of storms. Bands of showers and thunderstorms were revolving around the center of Hurricane Lee. Storms near the center of Lee’s circulation generated upper level divergence that pumped mass away from the hurricane.

Hurricane Lee was still a very large hurricane. Winds to hurricane force extended out 115 miles (185 km) from the center of Lee’s circulation. Winds to tropical storm force extended out 265 miles (425 km) from the center of circulation. The Hurricane Intensity Index (HII) was 17.8. The Hurricane Size Index (HSI) was 28.2 and the Hurricane Wind Intensity Size Index (HWISI) was 46.0. Hurricane Lee was similar in size and intensity to Hurricane Frances when Frances hit Southeast Florida in 2004.

Hurricane Lee will move through an environment that will become more unfavorable for a major hurricane during the next 24 hours. Lee will move over water where the Sea Surface Temperatures are near 28°C. An upper level trough over the eastern U.S. will produce southwesterly winds that will blow toward the top of Lee’s circulation. Those winds will cause the vertical wind shear to increase on Thursday. Hurricane Lee will move over cooler water later on Thursday. The combination of more vertical wind shear and cooler water will cause Hurricane Lee to weaken gradually during the next 24 hours.

Hurricane Lee will move around the western part of a subtropical high pressure system over the Atlantic Ocean. The high pressure system will steer Lee toward the north during the next 24 hours. On its anticipated track, the center of Hurricane Lee will pass west of Bermuda on Thursday evening. Bands in the eastern side of Lee’s circulation will bring gusty winds and locally heavy rain to Bermuda on Thursday.

Hurricane Lee could be east of Cape Cod by Saturday morning. Lee will affect Maine and Nova Scotia later on Saturday. Hurricane Lee could be in the middle of a transition to an extratropical cyclone on Saturday. Lee will bring strong, gusty winds and locally heavy rain to the coast of the Northeast U.S. and Nova Scotia. Heavy rain could cause flash floods in come locations. The winds blowing around the northern side of Hurricane Lee will push water toward the coast. A Storm Surge Watch has been issued for Cape Cod Bay and Nantucket, Massachusetts.

Elsewhere over the Atlantic Ocean, Hurricane Margot was spinning over the Central Atlantic. At 5:00 p.m. EDT on Wednesday the center of Hurricane Margot was located at latitude 34.7°N and longitude 40.6°W which put it about 790 miles (1270 km) west-southwest of the Azores. Margot was moving toward the north at 7 m.p.h. (11 km/h). The maximum sustained wind speed was 90 m.p.h. (145 km/h) and there were wind gusts to 105 m.p.h. (165 km/h). The minimum surface pressure was 971 mb.

Subtropical Storm Ernesto Forms West of the Azores

Subtropical Storm Ernesto formed west of the Azores on Wednesday morning.  At 11:00 a.m. EDT on Wednesday the center of Subtropical Storm Ernesto was located at latitude 38.1°N and longitude 46.0°W which put it about 695 miles (1120 km) southeast of Cape Race, Newfoundland.  Ernesto was moving toward the north 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 1008 mb.

More thunderstorms formed closer to the center of a low pressure system west of the Azores on Wednesday morning and the National Hurricane Center designated the system as Subtropical Storm Ernesto.  Several bands of showers and thunderstorms wrapped around the eastern and northern portions of the circulation.  Bands northwest of the center of Ernesto consisted primarily of showers and lower clouds.  The circulation may have been transporting some cooler, drier, more stable air into that part of the circulation.  Showers and thunderstorms around the center of Ernesto were generating upper level divergence which was pumping mass away to the northeast of the subtropical storm.

Subtropical Storm Ernesto will move through an environment that could support some intensification during the next day or so.  Ernesto will move over water where the Sea Surface Temperature is near 26°C.  It will move through a region where the upper level winds are not too strong and there will not be much vertical wind shear.  Subtropical Storm Ernesto could strengthen during the next 12 to 24 hours.  Ernesto will move over cooler water later on Thursday and it will start to weaken.  An upper level trough east of the U.S. will approach Subtropical Storm Ernesto from the west.  Southwesterly winds ahead of the trough will cause more vertical wind shear and Ernesto could make a transition to an extratropical cyclone.

The southwesterly winds ahead of the upper level trough will steer Subtropical Storm Ernesto in a general northeasterly direction.  On its anticipated track Subtropical Ernesto will pass between the Azores and Greenland.

Beryl Reorganizes as a Subtropical Storm North of Bermuda

A low pressure system associated with former Tropical Storm Beryl reorganized north of Bermuda on Saturday and the National Hurricane Center designated the system as Subtropical Storm Beryl.  At 2:00 p.m. EDT on Saturday the center of Subtropical Storm Beryl was located at latitude 36.4°N and longitude 65.7°W which put it about 575 miles (930 km) south-southwest of Halifax, Nova Scotia.  Beryl was moving toward the northeast 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 1010 mb.

The remnants of former Tropical Storm Beryl moved slowly across the northern Caribbean Sea and then over the southeastern Bahamas to a position northwest of Bermuda.  A low pressure system formed at the surface.  Bands of showers and thunderstorms developed and began to revolve around the the low pressure system.  The low pressure system moved under the eastern side of an upper level trough.  The trough contains colder air in the upper levels and it was also producing southwesterly winds which were blowing toward the top of the surface low pressure system.  The southwesterly winds were generating moderate vertical wind shear and the strongest rainbands were occurring on the eastern side of the surface low.  Some drier air was moving around the western and southern part of the upper level trough, which may have contributed to the weaker bands on the western side of the circulation.  The presence of the upper level trough and the asymmetrical distribution of thunderstorms around the surface low prompted the National Hurricane Center to designate the system as a subtropical storm.

Subtropical Storm Beryl will move through an environment marginally favorable for intensification during the next 24 hours.  Beryl will move over water where the Sea Surface Temperature is near 26°C.  The upper level trough will continue to produce moderate vertical wind shear.  The wind shear and the drier air will inhibit intensification.  Subtropical Storm Beryl could intensify a little more during the next 24 hours.  Beryl will move over colder water later on Sunday and it will start to weaken when that occurs.

The upper level trough was steering Subtropical Storm Beryl toward the northeast and a general motion in that direction is forecast to continue for several more days.  On its anticipated track Subtropical Storm Beryl will pass south of Nova Scotia on Sunday.  Beryl could be near Newfoundland by Tuesday.

Hurricane Chris Weakens South of Nova Scotia

Hurricane Chris weakened slowly on Wednesday as it passed well south of Nova Scotia.  At 11:00 p.m. EDT on Wednesday the center of Hurricane Chris was located at latitude 39.6°N and longitude 63.0°W.  Chris was moving toward the northeast at 29 m.p.h. (46 km/h).  The maximum sustained wind speed was 85 m.p.h. (140 km/h) and there were wind gusts to 100 m.p.h. (160 km/h).  The minimum surface pressure was 980 mb.

Hurricane Chris exhibited the structure of a hurricane on Thursday, but the clouds did not rise quite as high because it was over slightly cooler water.  There was still an eye at the center of circulation.  Several bands of showers and thunderstorms were revolving around the core of the circulation.  The rainbands were weaker in the southwestern part of the hurricane because some drier air was entering that part of the circulation.  Storms in the core of the circulation were generating upper level divergence.

Hurricane Chris is likely to weaken again on Thursday.  It will start to move over much cooler water where there is less energy in the upper ocean.  In addition an upper level trough over the eastern U.S. will produce southwesterly winds which will blow toward the upper part of the hurricane.  Those winds will cause strong vertical wind shear.  The shear will undercut the upper level divergence and tilt the circulation toward the northeast with height.  Hurricane Chris will start to make a transition to an extratropical cyclone when the effects of the cooler water and stronger shear begin to alter the structure of the hurricane.

The upper level trough was steering Hurricane Chris rapidly toward the northeast and that motion is expected to continue for several more days.  On its anticipated track Hurricane Chris will be near Labrador on Thursday night.  The extratropical cyclone that results from the transition of Hurricane Chris will be near Iceland during the weekend.

Chris Strengthens to a Hurricane Southeast of Cape Hatteras

Former Tropical Storm Chris strengthened to a hurricane southeast of Cape Hatteras on Tuesday.  At 5:00 p.m. EDT on Tuesday the center of Hurricane Chris was located at latitude 33.7°N and longitude 72.4°W which put it about 205 miles (330 km) east-southeast of Cape Hatteras, North Carolina.  Chris was moving toward the northeast at 10 m.p.h. (16 km/h).  The maximum sustained wind speed was 85 m.p.h. (135 km/h) and there were wind gusts to 100 m.p.h. (160 km/h).  The minimum surface pressure was 980 mb.

Hurricane Chris strengthened on Tuesday when it moved northeast of cooler water Chris had mixed to the surface while it was meandering off the coast of the Carolinas.  An eye with a diameter of 30 miles (50 km) formed at the center of circulation.  A ring of strong thunderstorms surrounded the eye and the strongest winds were occurring in the eastern side of that ring of storms.  Bands of showers and thunderstorms were revolving around the core of Hurricane Chris.  The strongest rainbands were in the eastern half of the circulation.  Drier air near the western half of the circulation was contributing to the weaker bands in that part of the hurricane.  Storms in the core of the circulation were generating upper level divergence which was pumping mass away to the north and east of the 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 95 miles (155 km) from the center.

Hurricane Chris will move through an environment favorable for intensification on Wednesday.  Chris will move over water where the Sea Surface Temperature is near 28°C.  An upper level trough over the northeastern U.S. will produce southwesterly winds that will blow toward the top of the hurricane.  The winds speeds are similar at most levels and they will not generate a lot of vertical wind shear during the next 24 hours.  Hurricane Chris will strengthen on Wednesday and it could intensify rapidly.  Chris will move over cooler water when it gets north of the Gulf Stream and it will start to weaken when that occurs.

The trough over the northeastern U.S. will steer Hurricane Chris toward the northeast.  On its anticipated track Chris will move away from the coast of North Carolina.  Chris could be south of Nova Scotia in about 36 hours and it could be near Newfoundland in several days.

Elsewhere, the remnants of former Tropical Storm Beryl crossed Hispaniola and they were moving toward the southeastern Bahamas.  At 2:00 p.m. EDT on Tuesday the center of Former Tropical Storm Chris was located at latitude 20.1°N and longitude 72.6°W which put it about 40 miles (65 km) northeast of Port de Paix, Haiti.  It was moving toward the northwest at 17 m.p.h. (28 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 1013 mb.  A reconnaissance aircraft is scheduled to investigate the system on Wednesday if there are signs that it could be reorganizing into a tropical cyclone.

Hurricane Gert Intensifies to Cat. 2 South of Nova Scotia

Hurricane Gert intensified to Category 2 on the Saffir-Simpson Scale as it sped over the Gulf Stream south of Nova Scotia on Wednesday afternoon.  At 5:00 p.m. EDT on Wednesday the center of Hurricane Gert was located at latitude 38.7°N and longitude 62.4°W which put it about 410 miles (665 km) south of Halifax, Nova Scotia.  Gert was moving toward the northeast at 31 m.p.h. (50 km/h).  The maximum sustained wind speed was 100 mp.h. (160 km/h) and there were wind gusts to 120 m.p.h. (195 km/h).  The minimum surface pressure was 970 mb.

Although Hurricane Gert is at a fairly high latitude, it has the classic structure of a Hurricane.  There is a fairly small eye at the center of circulation.  The eye is surround by a ring of strong thunderstorm and the strongest winds are occurring in this ring of thunderstorms.  There are additional bands of showers and thunderstorms revolving around the core of the hurricane.  The circulation is symmetrical and thunderstorms in the core are producing upper level divergence which is pumping away mass to the northeast of the hurricane.  Winds to hurricane force extend out about 40 miles (65 km) primarily to the east of the center of circulation.  Winds to tropical storm force extend out about 140 miles (225 km) from the center.

Hurricane Gert is moving over the Gulf Stream which means it is moving over water where the Sea Surface Temperature (SST) is near 28.5°C.  An upper level trough west of Gert is producing southwesterly winds which are blowing toward the top of the hurricane.  However, there is not much change of wind speed with height, which means that there is little vertical wind shear.  The combination of the warm water of the Gulf Stream and little vertical shear, allowed Hurricane Gert to strengthen on Wednesday.

Hurricane Gert could intensify during the next few hours, but it will soon move into a much less favorable environment.  Gert will soon move north of the Gulf Stream where the SSTs are much cooler.  The upper level trough is moving closer to Hurricane Gert and the winds are the upper level are forecast to get stronger.  When those winds increase, there will be much more vertical wind shear.  Colder water and more wind shear will cause Hurricane Gert to weaken on Thursday.  Gert could make a transition to an extratropical cyclone in colder environment of the North Atlantic.

Southwesterly winds in the upper level trough are steering Hurricane  Gert quickly toward the northeast and that general motion is expected to continue.  On its anticipated track, Hurricane Gert will move south of Labrador and Greenland.

Even as Hurricane Gert speeds away over the North Atlantic three new tropical waves over the tropical Atlantic have the potential to develop into tropical cyclones.  A tropical wave about 800 miles (1290 km) east of the Lesser Antilles designated as Invest 91L showed signs of organization on Wednesday.  A few more thunderstorms developed closed to the center of circulation.  A reconnaissance plane is scheduled to investigate this system on Thursday.  A little farther to the east another tropical wave designated Invest 92L was also showing evidence or more organization.  A third tropical wave just west of Africa also has the potential to develop during the next few days.
