Tropical Cyclone Anika Strengthens near Western Australia

Tropical Cyclone Anika strengthened near the coast of Western Australia on Tuesday night. At 10:00 p.m. EST on Tuesday the center of Tropical Cyclone Anika was located at latitude 19.1°S and longitude 121.1°E which put it about 70 miles (110 km) southwest of Bidyadanga, Australia. Anika was moving toward the southwest at 9 m.p.h (15 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 the portion of the coast from Bidyadanga to Pardoo.

Tropical Cyclone Anika strengthened a little near the coast of Western Australia southwest of Bidyadanga on Tuesday night. The inner end of a rainband wrapped around the southern and western sides of the center of Anika. Bands of showers and thunderstorms were revolving around the center of circulation. Storms near the center generated upper level divergence that pumped mass away from the tropical cyclone. Winds to tropical storm force extended out 60 miles (95 km) from the center of Tropical Cyclone Anika.

Tropical Cyclone Anika will move around the western part of a high pressure system over Australia during the next 36 hours. The high pressure system will steer Anika toward the south-southwest during the next 12 hours. On its anticipated track Tropical Cyclone Anika could make landfall on the coast of Western Australia near Wallal Downs in less than 12 hours. The high pressure system will steer Anika toward the south-southeast after it makes landfall.

Tropical Cyclone Anika will move through an environment favorable for intensification during the next 12 hours. Anika will move over water where the Sea Surface Temperatures are near 30˚C. It will move through are region where the upper level winds are weak and there will be little vertical wind shear. Tropical Cyclone Anika could strengthen during the next 12 hours. Anika will start to weaken after the center moves back over land.

Tropical Cyclone Anika will continue to bring gusty winds and locally heavy rain to parts of the coast of Western Australia. A Warning is in effect for the portion of the coast from Bidyadanga to Pardoo. Locally heavy rain could cause flash floods in some locations. Flood Watches are in effect for the Fitzroy River, the De Grey River and the Sandy Desert.

Elsewhere over the South Indian Ocean, Tropical Cyclone Vernon continued to churn southeast of Diego Garcia. At 10:00 p.m. EST on Tuesday the center of Tropical Cyclone Vernon was located at latitude 17.9°S and longitude 84.4°E which put it about 1095 miles (1765 km) southeast of Diego Garcia. Vernon was moving toward the southwest at 7 m.p.h (11 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 994 mb.

Tropical Cyclone Anika Moves Back over Water

The center of Tropical Cyclone Anika moved back over water on Monday night. At 10:00 p.m. EST on Monday the center of Tropical Cyclone Anika was located at latitude 16.7°S and longitude 122.5°E which put it about 85 miles (140 km) north of Broome, Australia.

The minimum surface pressure was 997 mb.

The center of Tropical Cyclone Anika moved back over water near Beagle Bay on Monday night. New thunderstorms began to develop near the center of Anika after the center moved back over water. The strongest thunderstorms were occurring in bands southwest of the center of circulation and northeast of the center. Bands in other parts of Tropical Cyclone Anika consisted primarily of showers and lower clouds. Storms near the center of Anika began to generated more upper level divergence.

Tropical Cyclone Anika will move around the northwestern part of a high pressure system over Australia during the next 24 hours. The high pressure system will steer Anika toward the southwest during that time period. Anika will move toward the south after it reaches the western end of the high pressure system in 24 hours. On its anticipated track Tropical Cyclone Anika could make landfall on the coast of Western Australia between Bidyadanga and De Grey in 42 hours.

Tropical Cyclone Anika will move through an environment favorable for intensification during the next 24 hours. Anika will move over water where the Sea Surface Temperatures are near 30˚C. It will move through are region where the upper level winds are weak and there will be little vertical wind shear. Tropical Cyclone Anika will strengthen during the next 24 hours. However a portion of Anika’s circulation will still be over land, which will inhibit intensification.

Tropical Cyclone Anika will continue to bring gusty winds and locally heavy rain to parts of the coast of Western Australia. A Warning is in effect for the portion of the coast from Beagle Bay to Bidyadanga. The Warning includes Broome. A Watch is in effect for the portion of the coast from Bidyadanga to De Grey. Locally heavy rain could cause flash floods in some locations. Flood Watches are in effect for the Fitzroy River, the De Grey River and the Sandy Desert.

Tropical Cyclone Anika moved along the coast of Western Australia on Sunday afternoon. The center of Anika’s circulation was still over land. The strongest winds were occurring in the northwestern quadrant of Tropical Cyclone Anika, which was still over water. Winds to tropical storm force extended out 70 miles (110 km) in the northwestern quadrant of Anika. The winds over land were blowing at less than tropical storm force.

A Warning was in effect for the portion of the coast from Troughton Island to Beagle Bay. The Warning included Cape Leveque and Derby. A Watch was in effect for the portion of the coast from Beagle Bay to Bidyadanga. The Watch included Broome.

The circulation around Tropical Cyclone Anika remained well organized even though the center was over land. The inner end of a rainband wrapped around the northern side of the center of Anika. The strongest thunderstorms were occurring in a bands in the western side of the circulation. There was also a strong band in the eastern periphery of Tropical Cyclone Anika. Bands in other parts of the circulation consisted primarily of showers and lower clouds. Storms near the center of circulation generated upper level divergence that pumped mass away from the tropical cyclone.

Tropical Cyclone Anika will move around the northwestern part of a high pressure system over Australia. The high pressure system will steer Anika toward the southwest during the next 24 hours. On its anticipated track Tropical Cyclone Anika will continue to move along the coast of Western Australia. Anika will bring gusty winds and locally heavy rain to places near the coast. Locally heavy rain could cause flash floods in some locations. Flood Warnings are in effect for the North Kimberly District and the West Kimberly District. Flood Watches are in effect for the Sandy Desert and for the Fitzroy River. The center of Anika could move back over water southwest of Kuri Bay on Monday.

Tropical Cyclone Anika is not likely to strengthen while the center is over land. However, since a portion of Anika’s circulation will be over water where the Sea Surface Temperatures are near 30˚C, it could maintain its current intensity. Tropical Cyclone Anika will move through an area where the upper level winds are weak and there will be little vertical wind shear. Anika could strengthen again, if the center of circulation moves back over water.

Elsewhere over the South Indian Ocean, Tropical Cyclone Vernon weakened east-southeast of Diego Garcia.
