Tropical Cyclone Narelle Hits Cape York Peninsula

Tropical Cyclone Narelle hit the Cape York Peninsula northwest of Cape Melville on Thursday.  At 11:00 p.m. EDT on Thursday the center of Tropical Cyclone Narelle was located at latitude 13.4°S and longitude 142.5°E which put the center about 50 miles (85 km) northwest of Coen, Australia.  Narelle was moving toward the west at 12 m.p.h. (19 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 951 mb.

The Australian Bureau of Meteorology issued a Warning for the east coast of the Cape York Peninsula that is in effect from Lockhart River to Cape Melville.  The Warning includes Coen.  A Warning is also in effect for the west coast of the Cape York Peninsula from Mapoon to Pormpuraaw.  That Warning includes Weipa.

A Watch is in effect for the portion of the west coast of the Gulf of Carpentaria from south of Nhulunbuy to Port McArthur.

Even though Tropical Cyclone Narelle weakened after it moved over the Cape York Peninsula, the circulation around Narelle was still intact.  A well defined center of circulation was visible on satellite images.  Bands of showers and thunderstorms were revolving around the center of Narelle’s circulation.

The circulation around Tropical Cyclone Narelle was still very symmetrical.  Winds to hurricane/typhoon force extended out 65 miles (105 km) from the center of Narelle’s circulation. Winds to tropical storm force extended out 165 miles (265 km) from the center of Tropical Cyclone Narelle.

The Hurricane Intensity Index (HII) for Tropical Cyclone Narelle is 22.1.  The Hurricane Size Index (HSI) is 20.1 and the Hurricane Wind Intensity Size Index (HWISI) is 42.1. Tropical Cyclone Narelle is similar in size and intensity to Hurricane Milton when Milton hit Florida in 2024.

Tropical Cyclone Narelle will continue to weaken during the next few hours while the center is over the Cape York Peninsula.  Narelle will move into an environment favorable for intensification when it moves over the Gulf of Carpentaria.  Narelle will move over water where the Sea Surface Temperatures are near 29°C.  It will move under the middle of an upper level ridge that is over the northern part of Australia.  The upper level winds are weak near the middle of the ridge and there will be little vertical wind shear.  Tropical Cyclone Narelle is likely to intensify again when it moves over the Gulf of Carpentaria.

Tropical Cyclone Narelle will move around the northern side of a high pressure system that is over Australia.  The high pressure system will steer Narelle toward the west during the next 24 hours.  On its anticipated track, Tropical Cyclone Narelle will move over the Gulf of Carpentaria in a few hours.

Tropical Cyclone Narelle will continue to bring strong winds and heavy rain to the northern part of the Cape York Peninsula during the next few hours.  Narelle will be capable of causing major damage.  Heavy rain is likely to cause flash floods in some locations.

Flood Watches are in effect for parts of the Cape York Peninsula and the North Tropical Coast of Queensland.

A Watch is in effect for the portion of the west coast of the Gulf of Carpentaria from south of Nhulunbuy to Port Mcarthur.

A circular eye with a diameter of 10 miles (16 km) was present at the center of Tropical Cyclone Narelle.  The eye was surrounded by a ring of thunderstorms and the strongest winds were occurring in that ring of storms.  Bands of showers and thunderstorms were revolving around the center of Narelle’s circulation.  Storms near the center of Narelle generated upper level divergence that pumped mass away from the tropical cyclone.  The removal of mass caused the surface pressure to decrease.

The size of the circulation around Tropical Cyclone Narelle increased on Wednesday night.  Winds to hurricane/typhoon force extended out 65 miles (105 km) from the center of Narelle’s circulation.  Winds to tropical storm force extended out 165 miles (265 km) from the center of Tropical Cyclone Narelle.

The Hurricane Intensity Index (HII) for Tropical Cyclone Narelle is 29.9.  The Hurricane Size Index (HSI) is 20.1 and the Hurricane Wind Intensity Size Index (HWISI) is 50.0.  Tropical Cyclone Narelle is similar in size and intensity to Hurricane Laura when Laura hit southwest Louisiana in 2020.

Tropical Cyclone Narelle will move through an environment that will be favorable for intensification during the next few hours. Narelle will move over water where the Sea Surface Temperatures are near 29°C.  It will move under the middle of an upper level ridge that is over the northern part of the Coral Sea.  The upper level winds are weak near the middle of the ridge and there will be little vertical wind shear.  Tropical Cyclone Narelle could intensify during the next few hours.

Tropical Cyclone Narelle will move around the northern side of a high pressure system that is over Australia.   The high pressure system will steer Narelle toward the west during the next 24 hours.   On its anticipated track, Tropical Cyclone Narelle will hit the coast of Queensland northwest of Cape Melville in a few hours.

Tropical Cyclone Narelle will bring very strong winds and heavy rain to the northern part of the Cape York Peninsula.  Narelle will be capable of causing severe damage.  Heavy rain is likely to cause flash floods in some locations.  Tropical Cyclone Narelle could also cause a storm surge of up to 13 feet (4 meters) along the coast near where the center of circulation makes landfall.

Flood Watches are in effect for parts of the Cape York Peninsula and the North Tropical Coast of Queensland.

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).

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.
