Tropical Cyclone Funani Brushes Rodrigues, Gelena Also a Threat

The western edge of Tropical Cyclone Funani brushed Rodrigues on Wednesday and Tropical Cyclone Gelena also posed a threat to the island.  At 4:00 p.m. EST on Wednesday the center of Tropical Cyclone Funani was located at latitude 18.1°S and longitude 65.1°E which put it about 515 miles (830 km) east-northeast of Port Louis, Mauritius and about 155 miles (250 km) northeast of Rodrigues.  Funani was moving toward the southeast at 7 m.p.h. (11 km/h).  The maximum sustained wind speed was 105 m.p.h. (170 km/h) and there were wind gusts to 125 m.p.h. (205 km/h).  The minimum surface pressure was 968 mb.

Tropical Cyclone Funani rapidly intensified into the equivalent of a hurricane/typhoon on Wednesday.  An eye was apparent on satellite images.  A ring of strong thunderstorms surrounded the eye and the strongest winds were occurring in that ring of storms.  Storms near the core of Funani generated strong upper level divergence which pumped mass away from the tropical cyclone.  Bands of showers and thunderstorms were revolving around the core of Tropical Cyclone Funani.  There were more bands in the eastern half of the circulation.  Winds to hurricane/typhoon force extended out about 35 miles (55 km) from the center of circulation.  Winds to tropical storm force extended out about 140 miles (225 km) from the center.

Tropical Cyclone Funani will be in an environment favorable for intensification for another 12 to 24 hours.  Funani will move over water where the Sea Surface Temperature is near 29°C.  It will move through an area where the upper level winds are weak and there will be little vertical wind shear.  Tropical Cyclone Funani could strengthen into the equivalent of a major hurricane during the next 24 hours.  Funani will move over cooler water at the end of the week and it will start to weaken in a less favorable environment.

Tropical Cyclone Funani is moving south of a subtropical ridge which is steering the tropical cyclone toward the southeast.  A general motion toward the southeast is expected to continue during the next few days.  On its anticipated track the core of Tropical Cyclone Funani will pass east of Rodrigues.  Surface observations on Rodrigues indicate that the western portion of Funani is dropping rain on that island, but winds are generally blowing at less than tropical storm force.

Tropical Cyclone Gelena also poses a threat to Rodrigues.  At 4:00 p.m. EST on Wednesday the center of Tropical Cyclone Gelena was located at latitude 12.5°S and longitude 53.2°E which put it about 535 miles (865 km) north-northwest of Port Louis, Mauritius.  Gelena was moving toward the south-southwest at 3 m.p.h. (5 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 987 mb.

Tropical Cyclone Gelena also intensified rapidly on Wednesday.  A tiny, pinhole eye was apparent on satellite imagery.  A thin ring of thunderstorms surrounded the eye and the strongest winds were occurring in that ring of storms.  Storms near the core of Gelena were generating upper level divergence which was pumping mass away from the tropical cyclone.  Bands of showers and thunderstorms were revolving around the core of Tropical Cyclone Gelena.  There were more bands in the northern half of the circulation.  Winds to tropical storm force extended out about 90 miles (150 km) from the center of circulation.

Tropical Cyclone Gelena will also move through an environment favorable for intensification.  Gelena will move over water where the Sea Surface Temperature is near 29°C.  It will move through an area where the upper level winds are weak and there will be little vertical wind shear.  Tropical Cyclone Gelena is likely to intensify into the equivalent of a hurricane/typhoon during the next 24 hours.  Gelena could strengthen into the equivalent of a major hurricane during the next several days.

Although Tropical Cyclone Gelena is currently weaker and smaller than Tropical Cyclone Funani, it may pose a greater risk to Rodrigues.  Gelena is forecast to pass closer to Rodrigues than Funani will pass and Gelena may be the equivalent of a major hurricane when it moves near Rodrigues.  Gelena could bring strong winds and heavy rain to Rodrigues in about 48 hours.

Tropical Cyclone Funani Develops Northeast of Mauritius

Tropical Cyclone Funani developed northeast of Mauritius on Tuesday.  At 10:00 p.m. EST on Tuesday the center of Tropical Cyclone Funani was located at latitude 15.8°S and longitude 64.0°E which put it about 505 miles (815 km) east-northeast of Port Louis, Mauritius and about 265 miles (425 km) north of Rodrigues.  Funani was moving toward the southwest at 5 m.p.h. (8 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 990 mb.

The circulation around Tropical Cyclone Funani organized quickly on Tuesday.  An inner rainband wrapped around the northern side of the center of circulation.  Bands of showers and thunderstorms developed and were revolving around the core of Funani.  There were more bands on the eastern side of the circulation.  Storms near the core began to generate upper level divergence which was pumping mass away from the tropical cyclone.  Winds to tropical storm force extended out about 120 miles (195 km) from the center of circulation.

Tropical Cyclone Funani will be moving through an environment favorable for intensification during the next several days.  Funani will be moving over water where the Sea Surface Temperature is near 29°C.  It will move under an area where the upper level winds are weak and there will be little vertical wind shear.  Tropical Cyclone Funani could intensify into the equivalent of a hurricane/typhoon within 24 hours and it could strengthen into the equivalent of a major hurricane in about 48 hours.

Tropical Cyclone Funani will move near the southeastern end of a subtropical ridge.  The ridge and a trough over the southwestern Indian Ocean will steer Funani in a general south-southwesterly direction.  On its anticipated track Tropical Cyclone Funani will remain east of Mauritius and La Reunion.  Funani could be near Rodrigues in about 24 hours.  It could be the equivalent of a hurricane/typhoon at that time.

Elsewhere over the South Pacific Ocean, Tropical Cyclone 13S formed east of Madagascar.  At 10:00 p.m. EST on Tuesday the center of Tropical Cyclone 13S was located at latitude 12.3°S and longitude 53.6°E which put it about 570 miles (920 km) north of Port Louis, Mauritius.  It was moving toward the west-northwest 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 1002 mb.

Tropical Cyclone Cilida Passes East of Mauritius

Strong Tropical Cyclone Cilida passed east of Mauritius on Saturday night.  At 10:00 p.m. EST on Saturday the center of Tropical Cyclone Cilida was located at latitude 20.2°S and longitude 60.3°E which put it about 170 miles (275 km) east of Port Louis, Mauritius.  Cilida was moving toward the south-southeast at 12 m.p.h. (19 km/h).  The maximum sustained wind speed was 115 m.p.h. (185 km/h) and there were wind gusts to 145 m.p.h. (230 km/h).  The minimum surface pressure was 953 mb.

Tropical Cyclone Cilida was being steered to the south-southeast between an upper level trough near Madagascar and a subtropical ridge over the South Indian Ocean.  Those weather systems steered Cilida east of Mauritius.  Northwesterly winds blowing on the eastern side of the upper level trough were causing vertical wind shear.  Tropical Cyclone Cilida was weakening, but it was still the equivalent of a major hurricane.  There was a circular eye at the center of Cilida.  The eye was surrounded by a ring of strong thunderstorms and the strongest winds were occurring in that ring of storms.  Several bands of showers and thunderstorms were revolving around the core of Tropical Cyclone Cilida.

Winds to hurricane/typhoon force extended out about 45 miles (75 km) from the center of Tropical Cyclone Cilida.  Winds to tropical storm force extended out about 115 miles (185 km) from the center.  Cilida passed far enough to the east of Mauritius that the strongest winds remained offshore.  A weather station at Belle Mare on the east coast of Mauritius reported a maximum wind speed of 38 m.p.h. (61 km/h).  An automated weather station on Signal Mountain reported a maximum wind speed of 49 m.p.h. (79 km/h).  Tropical Cyclone Cilida probably brought winds to tropical storm force to Mauritius, especially at higher elevations.

The stronger rainbands around Tropical Cyclone Cilida also passed east of Mauritius.  Cilida dropped light rain over most of Mauritius.  Heavier rain did fall over locations where the wind blew up the slopes of ridges and mountains.  1.44 inches (36.6 mm) of rain fell at Mon Bois and 1.31 inches (33.4 mm) fell at Mare Aux Vacoas.

The upper level trough over Madagascar will continue to steer Tropical Cyclone Cilida toward the south-southeast.  On its anticipated track Cilida will move farther away from Mauritius.  Tropical Cyclone Cilida will continue to weaken as it moves over cooler Sea Surface Temperatures and the vertical wind shear increases.

Powerful Tropical Cyclone Cilida Strengthens to Equivalent of Cat. 4 Hurricane

Powerful Tropical Cyclone Cilida strengthened to the equivalent of a Category 4 hurricane on the Saffir-Simpson Scale on Friday.  At 4:00 p.m. EST on Friday the center of Tropical Cyclone Cilida was located at latitude 15.9°S and longitude 57.8°E which put it about 310 miles (505 km) north of Port Louis, Mauritius.  Cilida was moving toward the south at 6 m.p.h. (10 km/h).  The maximum sustained wind speed was 150 m.p.h. (240 km/h) and there were wind gusts to 185 m.p.h. (295 km/h).  The minimum surface pressure was 931 mb.

The circulation of Tropical Cyclone Cilida was very well organized.  A circular eye was at the center of circulation.  The eye was surrounded by a ring of strong thunderstorms and the strongest winds were occurring in that ring of storms.  Several bands of showers and thunderstorms were revolving around the core of Tropical Cyclone Cilida.  Storms around the core were generating strong upper level divergence which was pumping mass away from the tropical cyclone.

The circulation around Tropical Cyclone Cilida was relatively small.  Winds to hurricane/typhoon force extended out about 35 miles (55 km) from the center of circulation.  Winds to tropical storm force only extended out about 95 miles (155 km) from the center.  The Hurricane Intensity Index (HII) for Tropical Cyclone Cilida was 31.6.  The Hurricane Size Index (HSI) was 11.0 and the Hurricane Wind Intensity Size Index (HWISI) was 42.6.

Tropical Cyclone Cilida may have peaked in intensity, but it will move through an environment capable of supporting a strong tropical cyclone for another 24 to 36 hours.  Cilida will move over water where the Sea Surface Temperature is near 28°C for about another 24 hours.  Then it will start to move over colder waters.  Tropical Cyclone Cilida will move toward the upper level westerly winds in the middle latitudes and the vertical wind shear will increase in about 36 hours.  When Cilida moves over colder water and under stronger upper level winds, it will weaken more quickly.

Tropical Cyclone Cilida is moving around the western end of a subtropical ridge over the South Indian Ocean.  The ridge will start to steer Cilida toward the southeast on Saturday.  On its anticipated track, the center of Tropical Cyclone Cilida could be a little northeast of Mauritius in about 24 hours.  It will still be a powerful tropical cyclone at that time.

Elsewhere over the South Indian Ocean, Tropical Cyclone Kenanga continued to weaken well to the southeast of Diego Garcia.  At 4:00 p.m. EST on Friday the center of Tropical Cyclone Kenanga was located at latitude 16.3°S and longitude 78.5°E which put it about 760 miles (1225 km) southeast of Diego Garcia.  Kenanga was moving toward the west at 7 m.p.h. (11 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 982 mb.

Tropical Cyclone Cilida Quickly Intensifies Into Equivalent of a Major Hurricane

Tropical Cyclone Cilida quickly intensified into the equivalent of a major hurricane north of Mauritius on Thursday.  At 10:00 p.m. EST on Thursday the center of Tropical Cyclone Cilida was located at latitude 14.5°N and longitude 58.0°E which put it about 410 miles (660 km) north of Port Louis, Mauritius.  Cilida was moving toward the southwest at 8 m.p.h. (13 km/h).  The maximum sustained wind speed was 120 m.p.h. (195 km/h) and there were wind gusts to 150 m.p.h. (240 km/h).  The minimum surface pressure was 949 mb.

Tropical Cyclone Cilida intensified quickly on Thursday.  A symmetrical, circular eye appeared more distinctly on satellite images.  The eye was surrounded by a ring of strong thunderstorms and the strongest winds were occurring in that ring of storms.  Several bands of showers and thunderstorms were revolving around the core of Tropical Cyclone Cilida.  Storms near the core of Cilida generated strong upper level divergence which pumped mass away from the tropical cyclone.  The removal of mass allowed the surface pressure to decrease rapidly and the wind speed increased in response to a larger pressure gradient force.  Winds to hurricane/typhoon force extended out about 35 miles (55 km) from the center of circulation.  Winds to tropical storm force extended out about 120 miles (195 km) from the center.

Tropical Cyclone Cilida will move through an environment favorable for strong tropical cyclones during the next 24 to 36 hours.  Cilida will move over water where the Sea Surface Temperature is near 28°C.  It will move through an area where the upper level winds are weak and there will be little vertical wind shear.  Tropical Cyclone Cilida will get stronger during the next day or so unless an eyewall replacement cycle begins.  If a rainband wraps around the existing eyewall, then an eyewall replacement cycle could cause Cilida to weaken.

Tropical Cyclone Cilida will move around the western end of a subtropical ridge over the South Indian Ocean.  The ridge is likely to steer Cilida toward the southwest for another 12 hours or so.  Tropical Cyclone Cilida will move more toward the south when it reaches the western end of the ridge.  In 36 to 48 hours Cilida will begin to be affected by the westerly winds in the middle latitudes and those winds will start to steer the tropical cyclone toward the southeast,  On its anticipated track Tropical Cyclone Cilida could approach Mauritius in about 36 hours.

Elsewhere over the South Indian Ocean Tropical Cyclone Kenanga weakened slowly well to the southeast of Diego Garcia.  At 10:00 p.m. EST on Thursday the center of Tropical Cyclone Kenanga was located at latitude 16.2°S and longitude 80.2°E which put it about 825 miles (1330 km) southeast of Diego Garcia.  Kenanga was moving toward the west-northwest at 6 m.p.h. (10 km/h).  The maximum sustained wind speed was 95 m.p.h. (155 km/h) and there were wind gusts to 115 m.p.h. (185 km/h).  The minimum surface pressure was 965 mb.

Tropical Cyclone Cilida Forms North of Mauritius

Tropical Cyclone Cilida formed north of Mauritius on Wednesday.  At 10:00 p.m. EST on Wednesday the center of Tropical Cyclone Cilida was located at latitude 12.2°S and longitude 59.8°E which put it about 585 miles (945 km) north-northeast of Port Louis, Mauritius.  Cilida was moving toward the southwest at 5 m.p.h. (8 km/h).  The maximum sustained wind speed was 55 m.p.h. (90 km/h) and there were wind gusts to 70 m.p.h. (110 km/h).  The minimum surface pressure was 989 mb.

The circulation around Tropical Cyclone Cilida organized quickly on Wednesday. A small circular eye formed at the center of circulation.  A ring of strong thunderstorms formed around the eye and the strongest winds were occurring in that ring of storms.  A strong band of storms wrapped around the western and northern sides of Cilida.  Other bands of showers and thunderstorms were revolving around the core of Tropical Cyclone Cilida.  Winds to tropical storm force extended out about 100 miles (160 km) from the center of circulation.

Tropical Storm Cilida will move through an environment favorable for intensification during the next 48 to 72 hours.  Cilida will move over water where the Sea Surface Temperature is near 27°C.  It will move through an area where the upper level winds are weak and there will be little vertical wind shear.  Cilida is likely to strengthen into the equivalent of a hurricane/typhoon on Thursday and it could intensify rapidly.  Tropical Cyclone Cilida could intensify into the equivalent of a major hurricane in two or three days.

Tropical Cyclone Cilida will move around the western end of a subtropical ridge.  The ridge will steer Cilida toward the south during the next several days.  On its anticipated track Tropical Cyclone Cilida could approach Mauritius from the north in about 48 hours.

Elsewhere over the South Indian Ocean Tropical Cyclone Kenanga drifted southeast of Diego Garcia.  At 10:00 p.m. EST on Wednesday the center Tropical Cyclone Kenanga was located at latitude 16.5°S and longitude 81.9°E which put it about 910 miles (1470 km) southeast of Diego Garcia.  Kenanga was stationary.  The maximum sustained wind speed was 125 m.p.h. (205 km/h) and there were wind gusts to 155 m.p.h. (250 km/h).  The minimum surface pressure was 947 mb.

Tropical Cyclone Kenanga Intensifies Into Equivalent of a Major Hurricane

Tropical Cyclone Kenanga intensified into the equivalent of a major hurricane on Tuesday.  At 10:00 p.m. EST on Tuesday the center of Tropical Cyclone Kenanga was located at latitude 15.9°S and longitude 82.6°E which put it about 920 miles (1485 km) southeast of Diego Garcia.  Kenanga was moving toward the southwest at 7 m.p.h. (11 km/h).  The maximum sustained wind speed was 130 m.p.h. (215 km/h) and there were wind gusts to 160 m.p.h. (260 km/h).  The minimum surface pressure was 944 mb.

Tropical Cyclone Kenanga intensified quickly into the equivalent of a major hurricane on Tuesday.  A large circular eye with a diameter of 50 miles (80 km) formed at the center of circulation.  A ring of strong thunderstorms surrounded the eye and the strongest winds were occurring in that ring of storms.  Bands of showers and thunderstorms were revolving around the core of Tropical Cyclone Kenanga.  Storms around the core of Kenanga were generating upper level divergence which was pumping mass away to the west and north of the tropical cyclone.  Winds to hurricane/typhoon force extended out about 60 miles (95 km) from the center of circulation.  Winds to tropical storm force extended out about 200 miles (320 km) from the center.

Tropical Cyclone Kenanga may be near its peak intensity.  Kenanga is over water where the Sea Surface Temperature is near 28°C, but it will start to move over slightly cooler water during the next day or two.  Tropical Cyclone Kenanga is in an area where the upper level winds are weak and there is little vertical wind shear.  However, Kenanga will move closer to upper level westerly winds in the middle latitudes later this week and the vertical wind shear will increase.  Tropical Cyclone Kenanga could maintain its intensity or weaken slowly during the next day or so.  Kenanga could weaken more quickly later this week.

Tropical Cyclone Kenanga will move south of a subtropical ridge over the South Indian Ocean.  The ridge will continue to steer Kenanga toward the southwest.  On its anticipated track Tropical Cyclone Kenanga will pass well to the south of Diego Garcia.

Elsewhere over the South Indian Ocean Tropical Cyclone 07S developed north-northeast of Mauritius.  At 10:00 p.m. EST on Tuesday the center of Tropical Cyclone 07S was located at latitude 10.9°S and longitude 60.8°E which put it about 690 miles (1115 km) north-northeast of Port Louis, Mauritius.  It was moving toward the south-southwest at 3 m.p.h. (5 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 998 mb

Tropical Cyclone Gaja Forms Over Bay of Bengal

Tropical Cyclone Gaja formed over the Bay of Bengal on Sunday.  At 4:00 p.m. EST on Sunday the center of Tropical Cyclone Gaja was located at latitude 12.9°N and longitude 86.7°E which put it about 500 miles (805 km) east of Chennai, India.  Gaja was moving toward the west-southwest 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 1002 mb.

An area of low pressure moving over the Bay of Bengal strengthened on Sunday and the India Meteorological Department classified the system as Tropical Cyclone Gaja.  The circulation around Tropical Cyclone Gaja is still organizing.  There is a distinct low level center of circulation.  A short band of thunderstorms is west and north of the center.  Several other bands of showers and thunderstorms are developing in other parts of Tropical Cyclone Gaja.  One stronger band is east of the center of circulation and another stronger band is southeast of the center.  Storms near the center are beginning to generate upper level divergence which will pump mass away from the tropical cyclone.

Tropical Cyclone Gaja will move through an environment somewhat favorable for intensification during the next 48 hours.  Gaja will move over water where the Sea Surface Temperature is near 29°C.  It will move south of an upper level ridge.  The ridge will produce easterly winds which will blow toward the top of the circulation.  The winds will cause some vertical wind shear, but the shear will not be strong enough to prevent intensification.  Tropical Cyclone Gaja will intensify and it could be nearly equivalent to a hurricane/typhoon in two or three days.

The upper level ridge will steer Tropical Cyclone Gaja in a generally west-southwesterly direction.  On its anticipated track Tropical Cyclone Gaja will approach the coast of southern India in about 72 hours.  Gaja could be nearly the equivalent of a hurricane/typhoon at that time.

Elsewhere, over the South Indian Ocean Tropical Cyclone Alcide still was moving slowly east of the northern end of Madgascar and Tropical Cyclone Bouchra developed between Diego Garcia and Cocos Island.  At 4:00 p.m. EST on Sunday the center of Tropical Cyclone Alcide was located at latitude 12.3°N and longitude 51.9°E which put it about 170 miles (275 km) east of Antisiranana, Madagascar.  Alcide was moving toward the northwest at 4 m.p.h. (6 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 997 mb.

At 4:00 p.m. EDT on Sunday the center of Tropical Cyclone Bouchra was located at latitude 5.4°S and longitude 89.1°E which put it about 700 miles (1130 km) northwest of Cocos Island, Australia.  Bouchra was moving toward the east 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 999 mb.

Tropical Cyclone Alcide Stalls East of Madgascar

Tropical Cyclone Alcide stalled east of northern Madagascar on Friday.  At 4:00 p.m. EDT on Friday the center of Tropical Cyclone Alcide was located at latitude 13.4°N and longitude 53.1°E which put it about 250 miles (400 km) east of Antisiranana, Madagascar.  Alcide was moving toward the south at 4 m.p.h. (6 km/h).  The maximum sustained wind speed was 75 m.p.h. (120 km/h) and there were wind gusts to 95 m.p.h. (155 km/h).  The minimum surface pressure was 978 mb.

Tropical Cyclone Alcide weakened during the past 36 hours.  An eye is no longer apparent on visible satellite images, although an eyelike feature persists on microwave satellite images.  There are breaks in the ring of thunderstorms surrounding the eye.  Winds to hurricane/typhoon force are occurring in the broken ring of storms.  Alcide moved very slowly during the past day or so.  Its slow movement may have allowed its winds to mix cooler water to the surface of the ocean.  If there is cooler water at the surface, then there is less energy available to support the circulation of Tropical Cyclone Alcide.  The circulation of Alcide remains relatively small.  Winds to tropical storm force extend out about 100 miles (160 km) from the center of circulation.

Tropical Cyclone Alcide is in an area where the steering currents are weak.  Alcide could meander over the same area for another day or so.  If it remains over the same cooler water, then Alcide will slowly weaken further.  As the circulation gets weaker, thunderstorms will not rise as high into the atmosphere and Tropical Cyclone Alcide will be steered by winds at lower levels.  If Alcide eventually moves over warmer water, and the upper level winds are not too strong, then new thunderstorms could develop.

Tropical Cyclone Alcide is not forecast to move much during the next 24 hours.  In a day or so the winds in the lower and middle troposphere are forecast to begin to steer Alcide in a more westerly direction.  On its anticipated track Tropical Cyclone Alcide could move closer to northern Madagascar on Sunday.

Tropical Cyclone Alcide Rapidly Intensifies Into Equivalent of Hurricane/Typhoon

Tropical Cyclone Alcide rapidly intensified into the equivalent of a hurricane/typhoon east of northern Madagascar on Wednesday.  At 10:00 a.m. EDT on Wednesday the center of Tropical Cyclone Alcide was located at latitude 10.6°S and longitude 55.7°W which put it about 675 miles (975 km) north of Port Louis, Mauritius.  Alcide was moving toward the west-southwest at 11 m.p.h. (17 km/h).  The maximum sustained wind speed was 85 m.p.h. (135 km/h) and there were wind gusts to 105 m.p.h. (170 km/h).  The minimum surface pressure was 972 mb.

The circulation around Tropical Cyclone Alcide organized rapidly during the past 24 hours.  An eye formed at the center of circulation.  A ring of strong thunderstorms surrounded the eye and the strongest winds were occurring in that ring of storms.  Several bands of showers and thunderstorms were revolving around the core of Alcide.  Storm near the core were generating upper level divergence which was pumping mass away from the tropical cyclone.

The circulation around Tropical Cyclone Alcide is relatively small.  Winds to hurricane/typhoon force extend out about 25 miles (40 km) from the center of circulation.  Winds to tropical storm force extend out about 80 miles (130 km) from the center.

Tropical Cyclone Alcide will move through an environment capable of supporting further intensification during the next 48 hours.  Alcide will move over water where the Sea Surface Temperature is near 27°C.  It will move near the western end of an upper level ridge.  The ridge will produce easterly winds which will blow toward the top of the circulation.  Those winds will cause some vertical wind shear, but the shear will not prevent intensification.  Tropical Cyclone Alcide could strengthen to the equivalent of a major hurricane during the next day or two.

The upper level ridge will steer Tropical Cyclone Alcide in a west-southwesterly direction.  On its anticipated track Alcide would stay north of Mauritius and La Reunion.  Tropical Cyclone Alcide could be east of northern Madagascar in a few days.
