Tropical Cyclone Tiffany made landfall near Port Roper, Australia on Tuesday night. At 10:00 p.m. EST on Tuesday the center of Tropical Cyclone Tiffany was located at latitude 14.9°S and longitude 134.7°E which put it about 45 miles (75 km) west of Port Roper, Australia. Tiffany was moving toward the west at 16 m.p.h. (26 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 991 mb.

The center of Tropical Cyclone Tiffany made landfall near Port Roper on the west coast of the Gulf of Carpentaria on Tuesday night. Tiffany was the equivalent of a strong tropical storm at the time of landfall. Winds to tropical storm force extended out 65 miles (105 km) from the center of circulation. Bands of showers and thunderstorms were dropping heavy rain over the region west of Port Roper. A Flood Watch was in effect for many of the rivers in the area.

Tropical Cyclone Tiffany will move around the northern side of a high pressure system over Australia. The high pressure system will steer Tiffany toward the west during the next 24 hours. On its anticipated track Tropical Cyclone Tiffany will move across the northern part of the Northern Territory. The center of Tiffany will pass near Ngukurr, Mataranka, Barunga and Katherine. Tropical Cyclone Tiffany will weaken gradually as it moves farther inland, but it will continue to drop heavy rain over the northern part of the Northern Territory. Locally heavy rain is likely to cause flash floods in some location.

Elsewhere over the South Pacific Ocean, Tropical Cyclone Cody was moving farther southwest of Fiji. At 10:00 p.m. EST on Tuesday the center of Tropical Cyclone Cody was located at latitude 23.1°S and longitude 174.1°E which put it about 435 miles (705 km) southwest of Suva, Fiji. Cody was moving toward the south at 12 m.p.h. (19 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).

Tropical Cyclone Tiffany Strengthens over Gulf of Carpentaria

Tropical Cyclone Tiffany strengthened over the Gulf of Carpentaria on Tuesday morning. At 10:00 a.m. EST on Tuesday the center of Tropical Cyclone Tiffany was located at latitude 15.2°S and longitude 137.4°E which put it about 100 miles (160 km) southeast of Groote Eylandt, Australia. Tiffany was moving toward the west at 16 m.p.h. (26 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 991 mb.

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

Tropical Cyclone Tiffany exhibited greater organization as it strengthened on Tuesday morning. The inner end of a rainband wrapped around the northern side of the center of circulation and a partial eyewall appeared to be developing. Bands of showers and thunderstorms were revolving around the center of Tiffany’s circulation. Storms near the center generated upper level divergence that pumped mass away to the west of the tropical cyclone. Winds to tropical storm force extended out 60 miles (95 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 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 during the next 12 hours.

Tropical Cyclone Tiffany will move around the northern side of a high pressure system over Australia during the next 24 hours. The high pressure system will steer Tiffany toward west. On its anticipated track the center of Tropical Cyclone Tiffany will pass south of Groote Eylandt during the next few hours. Tiffany will make landfall on the coast of the Northern Territory near Port Roper in about 12 hours. Tropical Cyclone Tiffany will bring gusty winds and locally heavy rain to the eastern part of the Northern Territory. Heavy rain could cause flash floods in some locations. Flood Watches have been issued for rivers in the eastern part of the Northern Territory.

Elsewhere over the South Pacific Ocean, Tropical Cyclone Cody was continued to churn southwest of Fiji. At 10:00 a.m. EST on Tuesday the center of Tropical Cyclone Cody was located at latitude 21.5°S and longitude 173.5°E which put it about 390 miles (625 km) southwest of Suva, Fiji. Cody was moving toward the south-southeast at 4 m.p.h. (6 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 991 mb.

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 Low Forms over Timor Sea

A Tropical Low formed over the Timor Sea north of Darwin, Australia on Thursday night. At 10:00 p.m. EST on Thursday the center of the Tropical Low was located at latitude 9.8°S and longitude 129.6°E which put it about 200 miles (325 km) north-northwest of Darwin, Australia. The Tropical Low was moving toward the south-southwest at 7 m.p.h. (11 km/h). The maximum sustained wind speed was 25 m.p.h. (40 km/h) and there were wind gusts to 35 m.p.h. (55 km/h). The minimum surface pressure was 1007 mb.

A Watch was issued for the portion of the coast from Point Stuart, Northern Territory to Kalumburu, Western Australia including Darwin and the Tiwi Islands.

A low pressure system over the Timor Sea north of Darwin, Australia exhibited more organization on Thursday night and the Australian Bureau of Meteorology designated the system as a Tropical Low. More thunderstorms formed in bands revolving around the center of the Tropical Low. The strongest rainbands were occurring in the western half of the circulation. 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 favorable for intensification during the next 24 hours. It will will move over water where the Sea Surface Temperatures are near 30˚C. The Tropical Low will move under the southwestern part of an upper level ridge centered north of Australia. The ridge will produce northwesterly 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 Tropical Low is likely to strengthen during the next 24 hours.

The Tropical Low will move around the western side of a high pressure system centered north of Australia during the next 24 hours. The high pressure system will steer the Tropical Low toward the south during the next day or so. On its anticipated track the Tropical Low could approach Bathurst Island and Melville Island within 24 hours. The Tropical Low could bring gusty winds and locally heavy rain to a portion of the coast of the Northern Territory during the weekend.

Tropical Cyclone Ferdinand Strengthens to Equivalent of Hurricane/Typhoon

Tropical Cyclone Ferdinand strengthened to the equivalent of a hurricane/typhoon over the South Indian Ocean northwest of Australia on Monday night.  At 10:00 p.m. EST on Monday the center of Tropical Cyclone Ferdinand was located at latitude 15.4°S and longitude 117.0°E which put it about 520 miles (840 km) north-northeast of Learmonth, Australia.  Ferdinand was moving toward the southwest at 5 m.p.h. (8 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 975 mb.

The circulation around Tropical Cyclone Ferdinand exhibited much greater organization on Monday.  A very small circular eye formed at the center of circulation.  The eye was surrounded by a ring of strong thunderstorms surrounded the eye and the strongest winds were occurring in that ring of storms.  Storms around the eye generated upper level divergence which was pumping mass away form the tropical cyclone.  Bands of showers and thunderstorms were revolving around the core of Ferdinand.  Winds to hurricane/typhoon force extended out 25 miles (40 km) from the center of circulation.  Winds to tropical storm force extended out 70 miles (100 km) from the center.

Tropical Cyclone Ferdinand will move through an environment favorable for intensification during the next 24 to 36 hours.  Ferdinand will move over water where the Sea Surface Temperature is near 29°C.  It will move under an upper level ridge over the South Indian Ocean northwest of Australia.  The upper level winds will be weak and there will be little vertical wind shear.  Tropical Cyclone Ferdinand will continue intensify and it could strengthen to the equivalent of a major hurricane during the next 24 to 36 hours.

Tropical Cyclone Ferdinand will move north of a high pressure system over the South Indian Ocean.  The high will steer Ferdinand slowly toward the west-southwest during the next several days.  On its anticipated track Tropical Cyclone Ferdinand will remain well to the northwest of Western Australia.

Elsewhere, Tropical Cyclone Esther was moving westward over the Northern Territory of Australia.  At 10:00 p.m. EST on Monday the center of Tropical Cyclone Esther was located at latitude 17.3°S and longitude 135.4°E which put it about 125 miles (200 km) east of Newcastle Waters, Australia.  Esther was moving toward the west at 7 m.p.h. (11km/h).  The maximum sustained wind speed was 35 m.p.h. (55 km/h) and there were wind gusts to 45 m.p.h.
