Tropical Cyclone 03S Makes Landfall in Western Australia

Tropical Cyclone 03S made landfall on the coast of Western Australia on Thursday night. At 10:00 p.m. EST on Thursday the center of Tropical Cyclone 03S was located at latitude 20.4°S and longitude 117.8°E which put it about 55 miles (90 km) west of Port Hedland, Australia. It was moving toward the southeast at 28 m.p.h. (45 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 994 mb.

Tropical Cyclone 03S made landfall on the coast of Western Australia west of Port Hedland on Thursday night. The tropical cyclone intensified slightly just before landfall. Winds to tropical storm force extended out 125 miles (200 km) from the center of circulation. The tropical cyclone brought gusty winds to the area around Port Hedland. A weather station in Port Hedland reported a sustained wind speed of 44 m.p.h. (71 km/h) and a wind gust of 56 m.p.h. (91 km/h).

Tropical Cyclone 03S will drop heavy rain over parts of Western Australia as it moves rapidly inland. Flood Warnings were in effect for the Pilbara Coastal Rivers, the Fortescue River, the De Grey River catchment, the Salt Lakes District Rivers, the Sandy Desert, and the Warburton District Rivers.

Elsewhere over the South Indian Ocean, Tropical Cyclone Bongoyo weakened east of Rodrigues. At 10:00 p.m. EST on Thursday the center of Tropical Cyclone Bongoyo was located at latitude 22.2°S and longitude 74.8°E which put it about 640 miles (1035 km) east of Rodrigues. It was moving toward the southwest at 7 m.p.h. (11 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.

Tropical Cyclone 03S Moves Toward Western Australia

Tropical Cyclone 03S moved toward Western Australia on Wednesday. At 10:00 p.m. EST on Wednesday the center of Tropical Cyclone 03S was located at latitude 14.5°S and longitude 111.8°E which put it about 595 miles (955 km) northwest of Port Hedland, Australia. It was moving toward the southeast 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 1000 mb.

There was a well defined low level center of circulation in Tropical Cyclone 03S, but the distribution of thunderstorms was asymmetrical. The strongest thunderstorms were occurring in bands southwest of the center. Bands north and east of the center consisted primarily of showers and lower clouds. Tropical Cyclone 03S was under the western part of an upper level ridge. The ridge was producing northeasterly winds which were blowing toward the top of the circulation. Those winds were causing moderate vertical wind shear and the shear was contributing to the asymmetrical distribution of thunderstorms. Winds to tropical storm force extended out 75 miles (120 km) from the center of circulation.

Tropical Cyclone 03S will move through an environment somewhat favorable for intensification during the next 36 hours. The tropical cyclone will move over water where the Sea Surface Temperature is near 29°C. The upper level ridge will still cause vertical wind shear, but the shear could decrease a little. The wind shear will inhibit intensification, but Tropical Cyclone 03S could strengthen during the next 36 hours.

Tropical Cyclone 03S will move around the southwestern part of a high pressure system over Australia. The high will steer the tropical cyclone toward the southeast. On its anticipated track Tropical Cyclone 03S will make landfall on the coast of Western Australia near Port Hedland in about 36 hours. The tropical cyclone will bring gusty winds and locally heavy rain to parts of Western Australia later this week.

Elsewhere over the South Indian Ocean, Tropical Cyclone Bongoyo moved slowly toward Rodrigues. At 4:00 p.m. EST on Wednesday the center of Tropical Cyclone Bongoyo was located at latitude 20.7°S and longitude 75.8°E which put it about 835 miles (1345 km) east of Rodrigues. Bongoyo was moving toward the southwest 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.

Tropical Cyclone Belna Strengthens to Equivalent of Hurricane/Typhoon North of Madagascar

Tropical Cyclone Belna strengthened to the equivalent of a hurricane/typhoon north of Madagascar on Friday.  At 4:00 p.m. EST on Friday the center of Tropical Cyclone Belna was located at latitude 9.4°N and longitude 48.2°E which put it about 440 miles (710 km) north-northeast of Mahajanga, Madagascar.  Belna was moving toward the south-southwest at 7 m.p.h. (11 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 979 mb.

Tropical Cyclone Belna continued to strengthen on Friday.  Microwave satellite images continued to indicate that an eye was in the process of forming.  The ring of thunderstorms around the developing eye got stronger and the strongest winds were found in that ring of storms.  More thunderstorms developed in the bands revolving around the core of Belna.  Storms near the core generated upper level divergence which pumped mass away from the tropical cyclone.

The circulation around Tropical Cyclone Belna was relatively small.  Winds to hurricane/typhoon force extended out 20 miles (30 km) from the center of circulation.  Winds to tropical storm force extended out 85 miles (135 km) from the center.

Tropical Cyclone Belna will move through an environment favorable for intensification during the next 24 to 48 hours.  Belna will move over water where the Sea Surface Temperature is near 28.5°C.  It will move through a region where the upper level winds will be weak and there will be little vertical wind shear.  Tropical Cyclone Belna will continue to intensify during the weekend and it could strengthen into the equivalent of a major hurricane.

Tropical Cyclone Belna will move around the western end of a subtropical high pressure system over the South Indian Ocean.  The high will steer Belna toward the south-southwest during the next several days.  On its anticipated track Tropical Cyclone Belna could approach the coast of Madagascar near Mahajanga in about three days.  Belna could be the equivalent of a major hurricane when it approaches the coast.

Elsewhere over the Southwest Pacific Ocean, Tropical Cyclone Ambali weakened almost as fast as it intensified on Thursday.  At 10:00 a.m. EST on Friday the center of Tropical Cyclone Ambali was located at latitude 11.7°S and longitude 62.1°E which put it about 670 miles (1080 km) north-northeast of Port Louis, Mauritius.  Ambali was moving toward the south at 7 m.p.h. (11 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 965 mb.

Tropical Cyclone Ambali Rapidly Intensifies to Threshold of Cat. 5

Tropical Cyclone Ambali rapidly intensified to the threshold of a Category 5 hurricane on the Saffir-Simpson Scale on Thursday.  At 10:00 p.m. EST on Thursday the center of Tropical Cyclone Ambali was located at latitude 10.8°S and longitude 62.1°E which put it about 740 miles (1190 km) north-northeast of Port Louis, Mauritius.  Ambali was moving toward the south-southwest at 7 m.p.h. (11 km/h).  The maximum sustained wind speed was 155 m.p.h. (250 km/h) and there were wind gusts to 190 m.p.h. (305 km/h).  The minimum surface pressure was 932 mb.

Tropical Cyclone Ambali rapidly intensified from a minimal tropical storm to the threshold of a Cat. 5 hurricane in less than 36 hours over the Southwest Indian Ocean.  Nearly perfect environmental conditions including warm water and little vertical wind shear allowed Ambali to strengthen very rapidly.  A small circular eye formed at the center of the tropical cyclone.  The eye was surrounded by 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 Ambali.

The circulation around Tropical Cyclone Ambali was small which also contributed to the rapid intensification.  Winds to hurricane/typhoon force extended out 25 miles (40 km) from the center of circulation.  Winds to tropical storm force extended out 100 miles (160 km) from the center.  The Hurricane Intensity Index (HII) for Tropical Cyclone Ambali was 33.3.  The Hurricane Size Index (HSI) was 7.9 and the Hurricane Wind Intensity Size Index (HWISI) was 41.2.

Tropical Cyclone Ambali may be near its maximum intensity, although it could strengthen a little more during the next six to twelve hours.  Ambali will move over water where the Sea Surface Temperature is near 28°C.  It will remain in an area where the upper level winds are weak during the next six to twelve hours and there will be little vertical wind shear during that time.  Tropical Cyclone Ambali will approach an area where there are strong upper level westerly winds during the weekend.  Ambali will weaken when the wind shear increases.

Tropical Cyclone Ambali will move around the western part of a subtropical high pressure over the South Indian Ocean.  The high will steer Ambali toward the south-southwest during the next several days.  On its anticipated track Tropical Cyclone Ambali will move toward Mauritius.

Elsewhere over the Southwest Indian Ocean, Tropical Cyclone Belna was intensifying north of Madagascar.  At 10:00 p.m. EST on Thursday the center of Tropical Cyclone Belna was located at latitude 7.5°S and longitude 49.0°E which put it about 300 miles (485 km) north of Madagsacar.  Belna was moving toward the southwest 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 982 mb.

The circulation around Tropical Cyclone Belna exhibited much greater organization on Thursday.  An eye appeared to be forming at the center of circulation on microwave satellite images.  The eye was surrounded by a ring of strong thunderstorms and the strongest winds were occurring in that ring of storms.  Bands of showers and thunderstorms were revolving about the core of Belna.  Storms near the core were generating upper level divergence which was pumping mass away from the tropical cyclone.  Winds to tropical storm force extended out 100 miles (160 km) from the center of circulation.

Tropical Cyclone Belna will move through an environment favorable for intensification during the next 24 to 48 hours.  Belna will move over water where the Sea Surface Temperature is near 28.5°C.  It will move through a region where the upper level winds are weak and there will be little vertical wind shear.  Tropical Cyclone Belna is likely to strengthen into the equivalent of a hurricane/typhoon on Friday.  Belna could intensify rapidly once an eye and eyewall are full formed.  It could strengthen into the equivalent of a major hurricane during the weekend.

Tropical Cyclone Belna will move around the western end of a ridge of high pressure over the South Indian Ocean.  The high will steer Belna toward the south-southwest during the next few days.  On its anticipated track Tropical Cyclone Blena could approach the coast of northwestern Madagascar in three or four days.  Belna could be the equivalent of a hurricane/typhoon when it approaches Madagascar.

Two Tropical Cyclones Form over Southwest Indian Ocean

One day after a pair of tropical cyclones developed over Arabian Sea, two tropical cyclones formed over the Southwest Indian Ocean on Wednesday.  At 4:00 p.m. EST on Wednesday the center of Tropical Cyclone 02S was located at latitude 6.9°S and longitude 51.2°E which put it about 355 miles (575 km) north of Madagascar.  The tropical cyclone was moving toward the south-southwest 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 1000 mb.

At 4:00 p.m. EST on Wednesday the center of Tropical Cyclone 03S was located at latitude 7.5°S and longitude 64.0°E which put it about 570 miles (915 km) west of Diego Garcia.  The tropical cyclone was moving toward the southwest at 9 m.p.h. (15 km/h).  The maximum sustained wind speed was 40 m.p.h. (65 km/h) snd there were wind gusts to 50 m.p.h. (80 km/h).  The minimum surface pressure was 1000 mb.

Tropical Cyclone 02S was still organizing on Wednesday afternoon and the distribution of thunderstorms was asymmetrical.  Many of the stronger thunderstorms were occurring in bands on the northern side of the circulation.  Bands on the southern side of the tropical cyclone consisted primarily of showers and lower clouds.  Storm near the center of circulation began to generate upper level divergence which was pumping mass away from the tropical cyclone.  Winds to tropical storm force extended out 30 miles (50 km) from the center.

Tropical Cyclone 02S will move through an environment favorable for intensification during the next 48 to 72 hours.  The tropical cyclone will move over water where the Sea Surface Temperature is near 28.5°C.  It will move through a region where there will be weak southeasterly winds in the upper levels.  Those winds will cause some vertical wind shear and they may already have contributed to the asymmetrical distribution of thunderstorms.  The wind shear will slow the rate of intensification, but the shear will not be enough to prevent the Tropical Cyclone 02S from getting stronger. The tropical cyclone could intensify into the equivalent of a hurricane/typhoon in 48 to 72 hours.

Tropical Cyclone 02S will move near the western end of a subtropical high pressure system over the South Indian Ocean.  The high will steer the tropical cyclone toward the south-southwest.  On its anticipated track Tropical Cyclone 02S could approach northern Madagascar in three or four days.

Tropical Cyclone 03S was also still organizing on Wednesday afternoon and it too had an asymmetrical distribution of thunderstorms.  The strongest thunderstorms around Tropical Cyclone 03S were occurring in bands south and west of the center of circulation.  Bands north and east of the center consisted primarily of showers and lower clouds.  Storms near the center of circulation were generating upper level divergence which was pumping mass away from the tropical cyclone.  Winds to tropical storm force extended out 35 miles (55 km) from the center.

Tropical Cyclone 03S will move through an environment favorable for intensification during the next 24 to 48 hours.  The tropical cyclone will move over water where the Sea Surface Temperature is near 28.5°C.  It will move through a region where the upper level winds will blow from the north.  Those winds will cause some vertical wind shear and they may have already contributed to the asymmetrical distribution of thunderstorms.  The wind shear will slow the rate of intensification but it will not be strong enough to prevent Tropical Cyclone 03S from getting stronger.

Tropical Cyclone 03S will also be steered by the subtropical high pressure system over the South Indian Ocean.  The high will steer the tropical cyclone toward the south-southwest.  On its anticipated track Tropical Cyclone 03S could move toward Mauritius.

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.

Tropical Cyclone Alcide Forms North of Mauritius

Tropical Cyclone Alcide formed north of Mauritius on Tuesday.  At 10:00 a.m. EDT on Tuesday the center of Tropical Cyclone Alcide was located at latitude 9.7°S and longitude 58.9°E which put it about 740 miles (1190 km) north of Port Louis, Mauritius.  Alcide was moving toward the west-southwest 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 999 mb.

A distinct center of circulation consolidated in an area of thunderstorms over the South Indian Ocean and the system was designated as Tropical Cyclone Alcide.  The circulation around Alcide was slowly becoming better organized.  The inner end of a band of thunderstorms was wrapping around the western side of the center of circulation.  Several other bands were developing south and west of the center.  Bands north and east of the center consisted primarily of showers and lower clouds.  Storms near the center of circulation were starting to generate upper level divergence which was pumping mass away from the core of the tropical cyclone.

Tropical Cyclone Alcide will move through an environment that will support intensification.  Alcide will move over water where the Sea Surface Temperature is near 27.5°C.  It will move around the northwestern side 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 which will slow the rate of intensification, but the winds are not likely to be strong enough to prevent intensification.  Tropical Cyclone Alcide could strengthen into the equivalent of a hurricane/typhoon during the next 48 to 72 hours.

The upper level ridge will steer Tropical Cyclone Alcide slowly toward the west-southwest during the next two or three days.  On its anticipated track Alcide could be northeast of Madagascar in a few days.  It could be the equivalent of a hurricane/typhoon at that time.

Tropical Low Forms Over Western Australia

A Tropical Low formed over Western Australia on Monday and a Tropical Cyclone Watch was issued for a portion of the coast.  At 2:00 p.m. EST on Monday the center of the Tropical Low was located at latitude 15.9°S and longitude 126.1°E which put it about 135 miles (220 km) west-southwest of Wyndham, Australia.  It was moving toward the southwest a 8 m.p.h. (13 km/h).  The maximum sustained wind speed was 20 m.p.h. (30 km/h) and there were wind gusts to 50 m.p.h. (85 km/h).  The minimum surface pressure was 1005 mb.  The Australia Bureau of Meteorology has issued a Tropical Cyclone Watch for the portion of the coast of Western Australia from Kuri Bay to Wallal Downs including Broome.

The circulation of the Tropical Low is still organizing.  There is a broad low level center of circulation, but there are not many showers and thunderstorms near the center.  There are numerous bands of showers and storms developing in bands on the eastern and western peripheries of the circulation.  The strongest wind gusts are occurring in those storms.  The lack of storms near the center of circulation is keeping the system from generating much upper level divergence.

The core of the Tropical Low is likely to remain over land for another 12-24 hours, which will inhibit the organization of the circulation.  When the center moves off the coast and over the South Indian Ocean, it will move into an environment favorable for intensification.  The Sea Surface Temperature of the water west of the coast of Western Australia is near 30°C.  The Tropical Low is moving north of the axis of a subtropical ridge.  The ridge is producing easterly winds which are blowing toward the top of the circulation, but there is not a lot of vertical wind shear.  The Tropical Low is likely to strengthen when it moves over water and it could intensify rapidly if a more concentrated center of circulation develops.

A subtropical ridge is current steering the Tropical Low toward the southwest, but a general motion toward the west-southwest is expected during the next 24 to 48 hours.  The Tropical Low will reach the western end of the ridge in about two days and then it will turn more toward the south.  On its anticipated track the center of the Tropical Low is expected to move off the coast between Kuri Bay and Derby on Tuesday.  The center is forecast to pass near Cape Leveque and then turn south toward Wallal Downs.

Elsewhere over the South Indian Ocean, Tropical Cyclone Ava continued to swirl near southern Madagascar and stronger Tropical Cyclone Irving was passing well to the south of Diego Garcia.  At 4:00 p.m. EST on Monday the center of Tropical Storm Ava was located at latitude 27.7°S and longitude 46.8°E which put it about 180 miles (295 km) south of Farodofay, Madagascar.  Ava was moving toward the west-southwest at 17 m.p.h. (27 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 994 mb.

At 4:00 p.m. EST on Monday the center of Tropical Cyclone Irving was centered at latitude 19.6°S and longitude 76.1°E which put it about 875 miles (1415 km) south-southeast of Diego Garcia.  Irving was moving toward the west-southwest at 18 m.p.h. (29 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 960 mb.  Tropical Cyclone Irving was the equivalent of a Category 2 hurricane on the Saffir-Simpson Scale.
