Tropical Cyclone Tiffany Crosses Cape York Peninsula

Tropical Cyclone Tiffany crossed the Cape York Peninsula on Monday. At 4:00 p.m. EST on Monday the center of Tropical Cyclone Tiffany was located at latitude 14.8°S and longitude 140.9°E which put it about 55 miles (90 km) west of Pormpuraaw, Australia. Tiffany was moving toward the west at 16 m.p.h. (26 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.

A Warning was in effect for Groote Eylandt. A Watch was in effect for the portion of the coast of the Northern Territory from Nhulunbuy to the border with Queensland. The Watch included Numbalwar, Port Roper and Port McArthur.

The center of Tropical Cyclone Tiffany emerged over the eastern Gulf of Carpentaria near Pormpuraaw on Monday after it moved westward across the Cape York Peninsula. New thunderstorms were forming in bands in the western and northern parts of Tiffany’s circulation. Bands in the eastern and southern parts of the circulation were still over land and those bands contained fewer thunderstorms. The strongest winds were occurring in the bands over the Gulf of Carpentaria. Winds to tropical storm force extended out 30 miles (50 km) from the center of Tropical Cyclone Tiffany.

Tropical Cyclone Tiffany will move through an environment favorable for intensification during the next 24 hours. Tiffany will move over water where the Sea Surface Temperatures are near 31˚C. It will move under the northern part of an upper level ridge over eastern Australia. The ridge will produce easterly winds that will blow toward the top of Tiffany’s circulation. Those winds will cause some vertical wind shear and the wind shear will inhibit intensification. However, Tropical Cyclone Tiffany will intensify over the warm water in the Gulf of Carpentaria. Tiffany could intensify rapidly once more of the circulation moves over water and it could strengthen to the equivalent of a hurricane/typhoon.

Tropical Cyclone Tiffany will move around the northern side of a high pressure system over Australia during the next 36 hours. The high pressure system will steer Tiffany toward west. On its anticipated track Tropical Cyclone Tiffany could approach Groote Eylandt in 24 hours. Tiffany could be the equivalent of a hurricane/typhoon when it approaches Groote Eylandt.

Elsewhere over the South Pacific Ocean, Tropical Cyclone Cody was continued to meander southwest of Fiji. At 4:00 p.m. EST on Monday the center of Tropical Cyclone Cody was located at latitude 20.9°S and longitude 174.1°E which put it about 330 miles (535 km) southwest of Suva, Fiji. Cody was moving toward the west at 13 m.p.h. (20 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 Tiffany Strengthens East of Cape York Peninsula

Tropical Cyclone Tiffany strengthened east of the Cape York Peninsula on Sunday morning. At 7:00 a.m. EST on Sunday the center of Tropical Cyclone Tiffany was located at latitude 13.9°S and longitude 145.9°E which put it about 120 miles (190 km) north-northeast of Cooktown, Australia. Tropical Cyclone was moving toward the west at 9 m.p.h. (14 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.

A Warning was in effect for the portion of the east coast of the Cape York Peninsula from Cape Grenville to Cape Tribulation. A Watch was in effect for the west coast of the Cape York Peninsula from Gilbert River Mouth to Mapoon.

A former Tropical Low east of the Cape York Peninsula strengthened quickly on Sunday morning and the Australian Bureau of Meteorology designated the system as Tropical Cyclone Tiffany. More Thunderstorms developed near the center of Tiffany’s circulation. More thunderstorms also formed in bands revolving around the center of Tropical Cyclone Tiffany. Storms near the center of circulation generated upper level divergence that pumped mass away from the tropical cyclone. Winds to tropical storm force extended out 70 miles (110 km) from the center of Tiffany.

Tropical Cyclone Tiffany will move through an environment favorable for intensification during the next 12 hours. Tiffany will move over water where the Sea Surface Temperatures are near 30˚C. It will move under the northwestern part of an upper level ridge centered east of Australia. The ridge will produce easterly winds that will blow toward the top of the Tropical Low’s circulation. Those winds will cause some vertical wind shear, but the shear will not be strong enough to prevent intensification. The center of Tropical Cyclone Tiffany will pass near Cape Melville in 12 hours. If some of the circulation on the southern side of Tiffany passes over land, that could inhibit intensification.

Tropical Cyclone Tiffany will move north of a high pressure system over Australia. The high pressure system will steer Tiffany toward the west during the next 36 hours. On its anticipated track the center of Tropical Cyclone Tiffany will pass just north of Cape Melville in 12 hours. Tiffany will make landfall on the east coast of the Cape York Peninsula east of Coen within 24 hours. Tropical Cyclone Tiffany will bring gusty winds and locally heavy rain to northern Queensland. Heavy rain is likely to cause flash floods in some locations.

Elsewhere over the South Pacific Ocean, Tropical Cyclone 05P was spinning between Fiji and Vanuatu. At 4:00 a.m. EST on Sunday the center of Tropical Cyclone 05P was located at latitude 18.9°S and longitude 176.3°E which put it about 150 miles (240 km) west of Tavuki, Fiji. Tropical Cyclone 05P was moving toward the east-southeast at 13 m.p.h. (20 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.

Two Tropical Lows Form over South Pacific

Two tropical lows formed over the South Pacific Ocean on Saturday morning. The first Tropical Low formed over the Coral Sea east of the Cape York Peninsula. At 7:00 a.m. EST on Saturday the center of that Tropical Low was located at latitude 13.0°S and longitude 147.8°E which put it about 240 miles (350 km) northeast of Cooktown, Australia. The Tropical Low was nearly stationary. 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 1004 mb.

A well defined low level center of circulation formed in a small low pressure system over the Coral Sea on Saturday morning and the Australian Bureau of Meteorology designated the system as a Tropical Low. A Watch was issued for the portion of the east coast of the Cape York Peninsula from Cape Grenville to Cape Tribulation. The distribution of thunderstorms around the Tropical Low was asymmetrical. The distribution of thunderstorms around the Tropical Low was asymmetrical. The strongest thunderstorms were occurring in bands in the northwestern quadrant of the circulation. Bands in other parts of the circulation consisted primarily of showers and lower clouds. Storms near the center began to generate upper level divergence that pumped mass away from the Tropical Low.

The Tropical Low will move through an environment somewhat favorable for intensification during the next 24 hours. The Tropical Low will move over water where the Sea Surface Temperatures are near 30˚C. It will move under the northwestern part of an upper level ridge centered east of Australia. The ridge will produce easterly winds that will blow toward the top of the Tropical Low’s circulation. Those winds will cause some vertical wind shear and the shear will inhibit intensification. The Tropical Low could intensify gradually during the next 24 hours.

The Tropical Low will move north of a high pressure system centered east of Australia. The high pressure system will steer the Tropical Low toward the west during the next 24 hours. On its anticipate track the Tropical Low could approach the eastern Cape York Peninsula between Lockhart River and Cooktown in 36 hours. It could be a named tropical cyclone when it approaches the coast.

The second Tropical Low developed over the South Pacific Ocean west of Fiji. At 10:00 a.m. EST on Saturday the center of the second Tropical Low was located at latitude 18.6°S and longitude 173.3°E which put it about 320 miles (515 km) west-southwest of Nadi, Fiji. That Tropical Low was moving toward the southeast 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.

A distinct low level center of circulation developed in a large low pressure system over the South Pacific Ocean west of Fiji and the Fiji Meteorological Service designated the system as a tropical low. The circulation around the second Tropical Low was much larger than the one over the Coral Sea, but the distribution of thunderstorms was also asymmetrical. The strongest thunderstorms were occurring in bands north and east of the center of circulation. Bands south and west of the center consisted primarily of showers and lower clouds. Storms near the center generated upper level divergence that pumped mass away from Tropical Low.

The second 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 Temperatures are near 30˚C. It will move through an area where the upper level winds are weak and there will be little vertical wind shear. The Tropical Low is likely to intensify into a named tropical cyclone during the next 24 hours.

The second Tropical Low will be in an area where the steering currents are weak during the next 24 hours. It is likely to meander slowly over the South Pacific Ocean between Fiji and Vanuatu during the next day or so.

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.

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.

Tropical Cyclone Trevor Brings Wind and Rain to Northern Queensland

Tropical Cyclone Trevor brought wind and rain to northern Queensland on Tuesday.  At 11:00 p.m. EDT on Tuesday the center of Tropical Cyclone Trevor was located at latitude 13.1°S and longitude 141.9°E which put it about 35 miles (55 km) south of Weipa, Australia.  Trevor was moving toward the west at 6 m.p.h. (10 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 973 mb.

A Tropical Cyclone Warning remained in effect for the west coast of the Cape York Peninsula from Cape York to Pormpuraaw.  The Australian Bureau of Meteorology issued a Tropical Cyclone Watch for the east coast of the Northern Territory from Nhulunbuy to the border between the Northern Territory and Queensland.

Tropical Cyclone Trevor made landfall on the east coast of the Cape York Peninsula near Lockhart River on Tuesday.  Trevor was the equivalent of a major hurricane when it made landfall.  Tropical Cyclone Trevor moved slowly westward across the peninsula to a position south of Weipa.  Trevor brought strong gusty winds and dropped locally heavy rain over the Cape York Peninsula.

Tropical Cyclone Trevor weakened steadily while it move over land.  The eye filled with lower clouds and the number of strong thunderstorms around the core and in the rainbands decreased.  However, the circulation remained intact.  Tropical Cyclone Trevor retained a well defined low level circulation with a distinct tight center.

The center of Tropical Cyclone Trevor will move over the eastern Gulf of Carpentaria in a few hours.  Trevor will move through an environment very favorable for intensification during the next several days.  It will move over water where the Sea Surface Temperature is near 31°C.  Tropical Cyclone Trevor will move through a region where the upper level winds are weak and there will be little vertical wind shear.  Trevor is likely to intensify when it moves back over water.  It could intensify rapidly once an eye and an eyewall redevelop at the core of the circulation.  Tropical Cyclone Trevor could strengthen into the equivalent of a major hurricane within 48 hours.

Tropical Cyclone Trevor will move around the northwestern part of a subtropical ridge.  The ridge will continue to steer Trevor toward the west for another day or so.  After that time Tropical Cyclone Trevor will move more toward the west-southwest.  On its anticipated track Trevor could reach the east coast of the Northern Territory in about 72 hours.  It is likely to be the equivalent of a major hurricane at that time.

Elsewhere, Tropical Cyclone Veronica developed quickly off the coast of Western Australia on Tuesday.  At 11:00 p.m. EDT on Tuesday the center of Tropical Cyclone Veronica was located at latitude 15.0°S and longitude 119.5°E which put it about 630 miles (1015 km) northeast of Learmonth, Australia.  Veronica was moving toward the west-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 990 mb.  Tropical Cyclone Veronica is also forecast to strengthen into the equivalent of a major hurricane and it could approach the coast of Western Australia in about four days.

Rapidly Intensifying Tropical Cyclone Trevor Nears Cape York Peninsula

Rapidly intensifying Tropical Cyclone Trevor neared the Cape York Peninsula on Monday.  At 5:00 p.m. EDT on Monday the center of Tropical Cyclone Trevor was located at latitude 13.0°S and longitude 144.3°E which put it about 80 miles (130 km) east of Lockhart River, Australia.  Trevor was moving toward the west-southwest at 5 m.p.h. (8 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 955 mb.

The Australian Bureau of Meteorology issued Tropical Cyclone Warnings for the portion of the east coast of the Cape York Peninsula from Orford Ness to Cape Flattery, from Mapoon to Pormpuraaw on the west coast of the peninsula and for inland locations between the two coasts.

Tropical Cyclone Trevor rapidly intensified into the equivalent of a hurricane/typhoon on Monday.  An eye with a diameter of 15 miles (24 km) developed at the center of circulation.  The eye was surround by a ring of strong thunderstorms and the strongest winds were occurring in that ring of storms.  Bands of showers and thunderstorms were revolving around the core of Tropical Cyclone Trevor.  Storms near the core were generating strong upper level divergence which was pumping mass away from the tropical cyclone in all directions.

The circulation around Tropical Cyclone Trevor was relatively small.  Winds to hurricane/typhoon force extended out about 30 miles (50 km) from the center of circulation.  Winds to tropical storm force extended out about 90 miles (145 km) from the center.  The Hurricane Intensity Index (HII) for Tropical Cyclone Trevor was 17.8.  The Hurricane Size Index (HSI) was 11.0 and the Hurricane Wind Intensity Size Index (HWISI) was 28.8.

Tropical Cyclone Trevor will remain in an environment favorable for intensification for another 12 hours until it makes landfall.  Trevor will move over water where the Sea Surface Temperature is near 30°C.  It will move through a region where the upper level winds are weak and there will be little vertical wind shear.  Tropical Cyclone Trevor could intensify into the equivalent of a major hurricane before it makes landfall.  It will take Trevor about 24 hours to cross the Cape York Peninsula.  Tropical Cyclone Trevor will weaken during that time.  Trevor will emerge over the Gulf of Carpentaria in about 36 hours and it will strengthen again after it gets back over water.

Tropical Cyclone Trevor will move around the northwestern portion of a subtropical ridge.  The ridge will steer Trevor toward the west-southwest.  On its anticipated track Tropical Cyclone Trevor will make landfall near or just to the south of Lockhart River in about 12 hours.    Trevor is forecast to move westward across the Cape York Peninsula.  it is likely to emerge over the Gulf of Carpentaria between Weipa and Aurukun in about 36 hours.  Tropical Cyclone Trevor will be capable of causing major damage.  It will bring strong winds and a storm surge to the area around Lockhart River.  Trevor will drop locally heavy rain over parts of the Cape York Peninsula and flooding could occur in some locations.  Tropical Cyclone Trevor could threaten the Northern Territory of Australia later this week.

Tropical Cyclone Penny Forms Over Gulf of Carpentaria

Tropical Cyclone Penny formed over the eastern Gulf of Carpentaria on Monday.  At 4:00 p.m. EST on Monday the center of Tropical Cyclone Penny was located at latitude 12.7°S and longitude 140.9°E which put it about 70 miles (110 km) west of Weipa, Australia.  Penny was moving toward the east-southeast at 5 m.p.h. (8 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 996 mb.

A Tropical Cyclone warming was in effect for the portion of the coast from Cape York to Pormpuraaw including adjacent coast areas.

A tropical low over the eastern Gulf of Carpentaria strengthened on Monday and the Australian Bureau of Meteorology designated the system as Tropical Cyclone Penny.  The circulation around Tropical Cyclone Penny was still organizing.  A band of showers of showers and thunderstorms wrapped around the western and northern sides of the center of circulation.  Other bands of showers and thunderstorms were revolving around the core of Tropical Cyclone Penny.  Storms near the core were generating upper level divergence which was pumping mass away from the tropical cyclone.

Tropical Cyclone Penny could strengthen during the next few hours.  Penny will move over water where the Sea Surface Temperature is near 30°C.   It will move through an area where the upper level winds are weaker and there will be little vertical wind shear.  Tropical Cyclone Penny will make landfall on the Cape York Peninsula near Weipa in about 12 hours.  Penny will weaken while it crosses northern Queensland.  Tropical Cyclone Penny could strengthen again when it moves over the Coral Sea in 24 to 36 hours.

Tropical Cyclone Penny will move south of a ridge centered northeast of Australia.  The ridge will steer Penny in an east-southeasterly direction.  On its anticipated track Tropical Cyclone Penny will make landfall on the Cape York Peninsula near Weipa in about 12 hours.  Penny could emerge over the Coral Sea south of the Lockhart River in 24 to 36 hours.

Tropical Cyclone Penny will bring rain and wind to the west coast of the Cape York Peninsula.  Penny will drop locally heavy rain over parts of northern Queensland.  The heavy rain could cause flooding.  A Flood Watch is in effect for coastal catchments north of Caldwell, Australia and the Cape York Peninsula.
