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.
