Anika was moving toward the southwest at 8 m.p.h (13 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.
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. At 1:00 p.m. EST on Sunday the center of Tropical Cyclone Vernon was located at latitude 12.4°S and longitude 88.3°E which put it about 1140 miles (1835 km) east-southeast of Diego Garcia. Vernon was moving toward the east at 13 m.p.h (09 km/h). The maximum sustained wind speed was 80 m.p.h. (130 km/h) and there were wind gusts to 100 m.p.h. (160 km/h).
