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.

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.

A Watch was issued for the west coast of the Gulf of Carpentaria from Nhulunbuy to the border between the Northern Territory and Queensland. The Watch included Groote Eylandt.

The center of Tropical Cyclone Tiffany made landfall on the east coast of Queensland east-southeast of Coen on Sunday night. Tiffany was the equivalent of a strong tropical storm at the time of landfall. Bands of showers and thunderstorms in the western half of Tiffany’s circulation brought gusty winds to northern Queensland. Winds to tropical storm force extended out 70 miles (110 km) from the center of circulation. Tropical Cyclone Tiffany was also dropping locally heavy rain over parts of northern Queensland. A Minor Flood Warning was issued for the Daintree River and a Flood Warning was issued for the Mossman River.

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 several days. On its anticipated track Tropical Cyclone Tiffany will move across the Cape York Peninsula during the next 18 hours. Tiffany will weaken while it moves over land. In 18 hours the center of Tropical Cyclone Tiffany will move over the Gulf of Carpentaria. The Sea Surface Temperatures are near 31˚C in the Gulf of Carpentaria. So, Tiffany could strengthen when it moves back over water. An upper level ridge over Australia will produce easterly winds that will blow toward the top of Tiffany’s circulation. Those winds will cause vertical wind shear and they will inhibit intensification, but Tropical Cyclone Tiffany is forecast to intensify after it moves over the Gulf of Carpentaria.

Elsewhere over the South Pacific Ocean, Tropical Cyclone Cody was located southwest of Fiji. At 10:00 p.m. EST on Sunday the center of Tropical Cyclone 05P was located at latitude 20.1°S and longitude 176.1°E which put it about 150 miles (240 km) west-southwest of Tavuki, Fiji.

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.

The minimum surface pressure was 974 mb.

After making a direct hit on Vanua Levu, Tropical Cyclone Yasa moved over the Fiji islands in the Lau Group. There were reports of damage and casualties from Fiji. Tropical Cyclone Yasa weakened after it made landfall on Vanua Levu. The eye and eyewall were disrupted by passage over land. An upper level low centered north of New Zealand produced northerly winds which blew toward the top of Yasa’s circulation on Friday. Those winds caused moderate vertical wind shear and the shear caused the tropical cyclone to weaken steadily on Friday.

The circulation around Tropical Cyclone Yasa exhibited less organization on Friday. The strongest thunderstorms were occurring in a band in the southern half of the circulation. Bands in the northern half of Yasa consisted primarily of showers and lower clouds. The circulation around Tropical Cyclone Yasa was still large. Winds to tropical storm force extended out 200 miles (320 km) from the center of circulation.

Tropical Cyclone Yasa will move through an environment that is mostly unfavorable for intensification during the next several days. Yasa will move over water where the Sea Surface Temperature is near 27°C. However, the upper level low centered north of New Zealand will continue to cause moderate vertical wind shear. The shear is likely to be strong enough to cause Tropical Cyclone Yasa to continue to weaken.

Tropical Cyclone Yasa will move around the eastern side of the upper level low. The low will steer Yasa toward the southwest during the next 48 hours. On its anticipated track Tropical Cyclone Yasa will pass west of Tonga and it will remain north of New Zealand.
