Tropical Cyclone Kimi Strengthens East of Queensland

Tropical Cyclone Kimi strengthened east of Queensland on Sunday. At 1:00 p.m. EST on Sunday the center of Tropical Cyclone Kimi was located at latitude 16.3°S and longitude 146.6°E which put it about 70 miles (110 km) northeast of Cairns, Australia. Kimi was moving toward the south 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 992 mb.

A Warning was in effect for the portion of the Queensland coast from Port Douglas to Lucinda. The Warning includes Cairns, Innisfail and Cardwell. A Watch was in effect for the portion of the coast from Lucinda to Ayr.

Tropical Cyclone Kimi strengthened as it moved parallel to the east coast of Queensland on Sunday. The Australian Bureau of Meteorology radar at Cairns showed a well defined center of circulation. The center was surrounded by a ring of strong thunderstorms and the strongest winds were occurring in that ring of storms. Storms near the center generated upper level divergence which pumped mass away from the tropical cyclone. Bands of showers and thunderstorms were revolving around the core of Kimi. Winds to tropical storm force extended out 50 miles (80 km) from the center of the tropical cyclone.

Tropical Cyclone Kimi will move through an environment favorable for intensification during the next 18 hours. Kimi will move over water where the Sea Surface Temperature is near 28°C. It will move under the axis of an upper level ridge east of Australia. The winds are weak near the axis of the ridge and there will be little vertical wind shear. Tropical Cyclone Kimi is likely to intensify during the next 18 hours. Kimi could strengthen to the equivalent of a hurricane/typhoon.

Tropical Cyclone Kimi will move around the northwestern part of a high pressure system east of Australia. The high will steer Kimi toward the south-southwest during the next 24 hours. On its anticipated track Tropical Cyclone Kimi could approach the coast of Queensland between Innisfail and Cardwell in 24 hours. Kimi could be the equivalent of a hurricane/typhoon or a strong tropical storm when it approaches the coast. Tropical Cyclone Kimi could drop heavy rain over parts of Queensland. The heavy rain could cause flash floods.

Tropical Cyclone Kimi Forms Near Queensland

Tropical Storm Kimi formed near the coast of Queensland on Saturday night. At 10:00 p.m. EST on Saturday the center of Tropical Cyclone Kimi was located at latitude 14.9°S and longitude 146.4°E which put it about 145 miles (235 km) north-northeast of Cairns, Australia. Kimi was moving toward the southwest at 6 m.p.h. (9 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 998 mb.

A Warning was issued for the portion of the coast from Cape Melville to Cardwell. The Warning included Cooktown, Port Douglas and Cairns.

The circulation around a small low pressure system near the coast of Queensland strengthened quickly on Saturday night and the Australian Bureau of Meteorology designated the system as Tropical Cyclone Kimi. The circulation around Kimi was small. Winds to tropical storm force extended out 60 miles (95 km) from the center of circulation. Storms near the center generated upper level divergence which pumped mass away from the tropical cyclone. Bands of showers and thunderstorms were revolving around the center of Kimi.

Tropical Cyclone Kimi will move through an environment favorable for intensification during the next 24 hours. Kimi will move over water where the Sea Surface Temperature is near 28°C. It will move under the axis of an upper level ridge east of Australia. The winds are weak near the axis of the ridge and there will be little vertical wind shear. Tropical Cyclone Kimi is likely to strengthen during the next 24 hours. Kimi could strengthen rapidly because the circulation is small.

Tropical Cyclone Kimi will move around the northwestern part of a high pressure system east of Australia. The high will steer Kimi toward the southwest during the next 24 hours. On its anticipated track Tropical Cyclone Kimi will approach the coast of Queensland between Cooktown and Port Douglas in less than 24 hours. Kimi could be the equivalent of a hurricane/typhoon or a strong tropical storm when it approaches the coast.

Tropical Cyclone Imogen Makes Landfall in Queensland

Tropical Cyclone Imogen made landfall in Queensland on Sunday. At 7:00 a.m. EST on Sunday the center of Tropical Cyclone Imogen was located at latitude 17.4°S and longitude 140.9°E which put it about 5 miles (10 km) north of Karumba, Australia. Imogen was moving toward the southeast at 11 m.p.h. (17 km/h). The maximum sustained wind speed was 50 m.p.h. (80 km/h) and there were wind gusts to 65 m.p.h. (105 km/h). The minimum surface pressure was 992 mb.

The tropical low over the southern Gulf of Carpentaria intensified into Tropical Cyclone Imogen before it made landfall in Queensland on Sunday. The center of Tropical Cyclone Imogen made landfall on the southwest coast of Queensland just to the north of Karumba. Imogen was the equivalent of a tropical storm at the time of landfall.

A Tropical Cyclone Warning was in effect for the portion of the coast of Queensland from Burketown to Kowanyama. The Warning extended inland to Croydon.

A high pressure system north of Australia will steer Tropical Cyclone Imogen toward the east southeast during the next 48 hours. On its anticipated track Tropical Cyclone Imogen could be near Croydon in about 12 hours. Imogen will move more slowly on Monday when the steering currents will be weaker. Tropical Cyclone Imogen could be north of Georgetown in about 36 hours. The circulation around Imogen will weaken as it moves farther inland. Imogen will drop heavy rain over parts of the southern Cape York Peninsula. Heavy rain could cause flash floods along some rivers and streams. Flood Watches and Warnings are in effect for parts of northern Queensland.

Tropical Low Strengthens over Gulf of Carpentaria

A tropical low strengthened over the Gulf of Carpentaria on Saturday. At 1:00 p.m. EST on Saturday the center of the tropical low was located at latitude 15.8°S and longitude 138.5°E which put it about 75 miles (120 km) northwest of Mornington Island. The tropical low was moving toward the southeast at 7 m.p.h. (11 km/h). The maximum sustained wind speed was 35 m.p.h. (55 km/h) and there were wind gusts to 45 m.p.h. (75 km/h). The minimum surface pressure was 998 mb.

A Watch was in effect for the portion of the coast from the border between the Northern Territory and Queensland to Pormpuraaw. The Watch included Mornington Island.

The circulation around the tropical low exhibited better organization on Saturday. More thunderstorms developed near the center of circulation. Storms near the center generated upper level divergence which pumped mass away from the tropical low. The removal of mass was causing the surface pressure to decrease. Bands of showers and thunderstorms were revolving around the center of the tropical low.

The tropical low will move through an environment favorable for intensification during the next 24 hours. The tropical low will move over water where the Sea Surface Temperature is near 30°C. It will move under the axis of an upper level ridge where the winds are weak. There will be little vertical wind shear. The tropical low will strengthen during the next 24 hours and it is likely to intensify to the equivalent of a tropical storm.

The tropical low will move south of a high pressure system centered north of Australia. The high will steer the tropical low toward the southeast during the next 24 hours. On its anticipated track the tropical low will make landfall on the coast of Queensland between Karumba and Gilbert River Mouth in about 24 hours. It will be the equivalent of a tropical storm when it makes landfall. The tropical low could stall when it moves inland, which would cause a prolonged period of heavy rain. Flash floods could occur in parts of northern Queensland.

Tropical Cyclone Esther Makes Landfall in Northern Australia

Tropical Cyclone Esther made landfall in northern Australia just to the east of the border between Queensland and the Northern Territory on Sunday night.  At 10:00 p.m. EST on Sunday the center of Tropical Cyclone Esther was located at latitude 16.7°S and longitude 137.9°E which put it about 65 miles (105 km) west of Mornington Island.  Esther was moving toward the west-southwest at 10 m.p.h. (16 km/h).  The maximum sustained wind speed was 50 m.p.h. (80 km/h) and there were wind gusts to 65 m.p.h. (105 km/h).  The minimum surface pressure was 988 mb.

A Warning remained in effect for the portion of the coast from Port McArthur to Karumba, Australia including Borroloola and Mornington Island.

Tropical Cyclone Esther was intensifying slowly when it made landfall just east of the border between Queensland and the Northern Territory of Australia.  Winds to tropical storm force extended out 75 miles (120 km) from the center of circulation.  A weather station at Mornington Island reported a sustained wind speed of 35 m.p.h. (57 km/h) and a wind gust of 54 m.p.h. (87 km/h).  The station measured 6.77 inches (172 mm) of rain.

Tropical Cyclone Esther will weaken as it moves inland.  Esther will move north of a high pressure system over Australia.  The high will steer Tropical Cyclone Esther toward the west during the next few days.  On its anticipated track Esther will move across the Northern Territory.  Tropical Cyclone Esther will drop locally heavy rain and it could cause flash floods in some locations.  There is a potential for Esther to strengthen again in a few days when it moves over the South Indian Ocean northwest of Australia.

Elsewhere, Tropical Cyclone Ferdinand developed over the South Indian Ocean northwest of Australia.  At 4:00 p.m. EST on Sunday the center of Tropical Storm Ferdinand was located at latitude 13.8°S and longitude 117.8°E which put it about 450 miles (750 km) north of Port Hedland, Australia.  Ferdinand was moving toward the southwest at 7 m.p.h. (11 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 993 mb.  Tropical Cyclone Ferdinand is forecast to move toward the west-southwest and to strengthen into the equivalent of a hurricane/typhoon.

Tropical Cyclone Esther Develops Over Southern Gulf of Carpentaria

Tropical Cyclone Esther developed over the southern Gulf of Carpentaria on Sunday.  At 1:00 p.m. EST on Monday the center of Tropical Cyclone Esther was located at latitude 16.0°S and longitude 139.1°E which put it about 50 miles (80 km) north of Mornington Island.  Esther was moving toward the southwest at 6 m.p.h. (10 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 991 mb.

The Australian Bureau of Meteorology issued a warning for the portion of the coast from Port Roper to Gilbert River Mouth including Borroloola and Mornington Island.

A Tropical Low over the southern Gulf of Carpentaria strengthened into Tropical Cyclone Esther on Sunday.  The circulation around Esther was large.  Winds to tropical storm force extended out about 125 miles (200 km) from the center of circulation.  There were a few thunderstorms near the center.  Most of the thunderstorms were in two large bands in the outer part of the circulation.  One of the bands was south of the center of Tropical Cyclone Esther and the other band was north of the center of circulation.

Tropical Storm Esther will move through an environment favorable for intensification during the next 12 hours.  Esther will move over water where the Sea Surface Temperature is near 30°C.  It will move under and upper level ridge.  The upper level winds will be weak and there will be little vertical wind shear.  Esther could make intensify before it makes landfall on the coast of Australia.

Tropical Cyclone Esther will move around the northwestern part of a high pressure system during the next 12 to 24 hours.  The high will steer Esther toward the southwest.  On its anticipated track Tropical Cyclone Esther could make landfall on the coast of Australia near the border between Queensland and the Northern Territory in about 12 hours.  Esther will bring gusty winds to coastal locations.  Tropical Cyclone Esther is already dropping locally heavy rain over far northwestern Queensland and the eastern part of the Northern Territory.  Flood watches have been issued for river basins near the Gulf of Carpentaria.  Esther could move westward across the Northern Territory after it makes landfall.

Tropical Low Strengthens Over Gulf of Carpentaria

A Tropical Low designated as Invest 99P by some agencies strengthened over the Gulf of Carpentaria on Saturday.  At 4:00 p.m. EST on Saturday the center of the Tropical Low was located at latitude 14.3°S and longitude 138.2°E which put it about 110 miles (180 km) east of Groote Eylandt, Australia.  The Tropical Low was moving toward the south 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 1000 mb.

The Australian Bureau of Meteorology issued a Warning for the portion of the coast from Numbulwar to Kowanyama including Mornington Island.

More bands of thunderstorms began to develop around a Tropical Low on Saturday.  The bands were revolving around the center of circulation.  The Tropical Low will move through an environment favorable for intensification during the next 24 hours.  It will move over water where the Sea Surface Temperature is near 30°C.  The Tropical Low is under an upper level ridge and the upper level winds are weak.  There will be little vertical wind shear and the Tropical Low is forecast to strengthen into a tropical cyclone.

The Tropical Low will move around the western end of a high pressure system.  The high will steer the Low toward the south.  On its anticipated track the Tropical Low will approach the coast of Australia near the border between Queensland and the Northern Territory.  It will bring gusty winds and locally heavy rain.  Heavy rain could cause flash floods in some locations.

Weaker Tropical Cyclone Ann Nears Northern Queensland

A weaker Tropical Cyclone Ann neared northern Queensland on Monday.  At 11:00 p.m. EDT on Monday the center of Tropical Cyclone Ann was located at latitude 14.4°S and longitude 148.4°E which put it about 230 miles (370 km) east-northeast of Cooktown, Australia.  Ann was moving toward the west-northwest at 14 m.p.h. (22km/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 996 mb.  The Australian Bureau of Meteorology issued a Tropical Cyclone Warning that extended from Lockhart River to Cooktown including Coen and Lizard Island.

The circulation around Tropical Cyclone Ann weakened on Monday because of a drier, more stable environment and more vertical wind shear.  Low level convergence pulled drier, more stable air closer to the center of Tropical Cyclone Ann.  The drier, more stable air caused many of the stronger thunderstorms to weaken.  Despite the drier, more stable environment stronger thunderstorms redeveloped south of the center of circulation late on Monday.  Tropical Cyclone Ann was moving near the northwestern portion of an upper level ridge.  The ridge produced easterly winds which caused moderate vertical wind shear.  The wind shear also contributed to the weakening of storms in the northern half of the circulation.

Tropical Cyclone Ann continued to have a distinct low level center of circulation despite the less favorable environment.  However, the wind field exhibited a more asymmetric structure.  The strongest winds were occurring in an area of thunderstorms south of the center of circulation.  Winds to tropical storm force extended out about 100 miles (160 km) from the center in the southern half of the circulation.  Winds to tropical storm force only extended out about 50 miles (80 km) from the center in the northern half of the circulation.

Tropical Cyclone Ann will continue to move through a less favorable environment during the next 24 hours.  Ann will move over water in the Coral Sea where the Sea Surface Temperature is near 27.5°C.  It will continue to move through a region where there is drier, more stable air and the upper level ridge will continue to cause moderate vertical wind shear.  The drier, more stable air and moderate vertical wind shear will prevent significant intensification.  Tropical Cyclone Ann could maintain its intensity during the next 12 hours, but it may weaken when it approaches the coast of the Cape York Peninsula.

Tropical Cyclone Ann will move north of a ridge which will steer Ann toward the west-northwest.  On its anticipated track Tropical Cyclone Ann will make landfall on the Cape York Peninsula in northern Queensland in about 24 hours.  Ann will bring some gusty winds, but the greatest risk will be locally heavy rain.

Tropical Cyclone Ann Strengthens Over Coral Sea

Tropical Cyclone Ann strengthened over the Coral Sea on Sunday.  At 11:00 p.m. EDT on Sunday the center of Tropical Cyclone Ann was located at latitude 15.4°S and longitude 153.6°E which put it about 565 miles (910 km) east of Cairns, Australia.  Ann was moving toward the west-northwest at 15 m.p.h. (24 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 987 mb.

The circulation around Tropical Cyclone Ann exhibited greater organization on Sunday.  There were indications on satellite images that a cloud filled eye might be trying to form at the center of circulation.  A broken ring of 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 Tropical Cyclone Ann.  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 about 100 miles (160 km) from the center of circulation.

Tropical Cyclone Ann will be moving through an environment that contains factors favorable for intensification and a factor that will inhibit potential intensification.  Ann will move over water where the Sea Surface Temperature is near 28°C.  So, there will be sufficient energy in the upper ocean to support intensification.  Tropical Cyclone Ann will move north 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 be strong enough to prevent intensification.  Tropical Cyclone Ann is surrounded by drier more stable air and the drier air is the factor that will inhibit intensification.  So far, the circulation around Ann has kept the drier air outside the tropical cyclone.  If the drier air remains outside the circulation, then Tropical Cyclone Ann would have a chance to strengthen.  However, if the drier air gets pulled into the circulation, then Ann will weaken.  The higher probability is that Tropical Cyclone Ann could maintain its intensity or weaken slowly during the next day or two depending on what happens to the drier air.

Tropical Cyclone Ann will move north of an area of high pressure, which will steer the tropical cyclone toward the west-northwest.  On its anticipated track Ann will approach the Cape York Peninsula north of Coen in less than 48 hours.  Tropical Cyclone Ann could bring gusty winds and locally heavy rain to northern Queensland.

Tropical Cyclone Ann Forms Over Coral Sea

Tropical Cyclone Ann formed over the Coral Sea on Saturday.  At 5:00 p.m. EDT on Saturday the center of Tropical Cyclone Ann was located at latitude 16.3°S and longitude 158.7°E which put it about 875 miles (1410 km) east of Cairns, Australia.  Ann was moving toward the west 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 999 mb.

A distinct low level center of circulation became more evident in satellite images of a low pressure system over the eastern Coral Sea on Saturday and the system was designated as Tropical Cyclone Ann.  A rainband wrapped around the southern and western sides of the center of circulation.  A microwave satellite image indicated that the band may have wrapped completely around the center in the middle levels of the circulation.  Storms near the center of circulation began to generate upper level divergence which was pumping mass away from the tropical cyclone.  The circulation around Tropical Cyclone Ann was relatively small.  Winds to tropical storm force extended out about 85 miles (135 km) from the center of circulation in the southern half of Ann.

Tropical Cyclone Ann will move through an environment somewhat favorable for intensification during the next day or two.  Ann will move over water where the Sea Surface Temperature is near 28.5°C.  It will move south of an upper level ridge.  The ridge will produce easterly winds which will cause some vertical wind shear.  The shear will inhibit intensification, but it is not likely to be strong enough to prevent intensification.  Tropical Cyclone Ann is likely to intensify during the next 24 hours.

The ridge will steer Tropical Cyclone Ann toward the west-northwest during the next two to three days.  On its anticipated track Tropical Cyclone Ann will approach the Cape York Peninsula in northern Queensland in about 72 hours.  Ann could bring gusty winds and locally heavy rain.

Elsewhere around the tropics in the southern hemisphere, Tropical Cyclone Lili was weakening near the coast of East Timor.  At 5:00 p.m. EDT on Saturday the center of Tropical Cyclone Lili was located at latitude 9.1°S and longitude 126.8°E which put it about 120 miles (195 km) east-northeast of Suai, East Timor.  Lili was moving toward the west at 4 m.p.h. (6 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 1000 mb.
