The center of Tropical Cyclone Anika made another landfall on the coast of Western Australia just to the west of Wallal Downs on Wednesday morning. Anika strengthened as it approached the coast. More thunderstorms developed near the center of Anika’s circulation. The inner end of a rainband wrapped around the southern and eastern sides of the center of circulation. Winds to tropical storm force extended out 60 miles (90 km) from the center of Tropical Cyclone Anika.

Tropical Cyclone Anika will move around the southwestern part of a high pressure system over Australia during the next 36 hours. The high will steer Anika toward the south-southeast. On its anticipated track Tropical Cyclone Anika will move inland over Western Australia. The center of Anika could pass west of Telfer on Thursday. Tropical Cyclone Anika will bring gusty winds and locally heavy rains to parts of Western Australia. A Flood Warning is in effect for the Sandy Desert. Flood Watches are in effect for the Fitzroy River and the De Grey River. Anika will weaken gradually as it moves farther inland.

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 Damien Strengthens to Equivalent of Hurricane/Typhoon

Tropical Cyclone Damien strengthened to the equivalent of a hurricane/typhoon on Thursday night.  At 10:00 p.m. EST on Thursday the center of Tropical Cyclone Damien was located at latitude 18.0°S and longitude 117.2°E which put it about 190 miles (310 km) north of Karratha, Australia.  Damien was moving toward the southwest at 7 m.p.h. (11 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 979 mb.

A Warning was in effect for the portion of the coast of Western Australia from Wallal Downs to Mardie including Port Hedland, Karratha and Dampier.  A Watch was in effect for the coast from Mardia to Onslow.

Tropical Cyclone Damien organized quickly on Thursday.  Microwave satellite imagery suggested that a small eye could be forming at the center of Damien.  A small ring of thunderstorms surrounded the forming eye and the strongest winds were occurring in that ring of storms.  Bands of showers and thunderstorms were revolving around the core of Tropical Cyclone Damien.  Storms near the core were generating upper level divergence which was pumping mass away from the tropical cyclone.  Winds to tropical storm force extended out 90 miles (145 km) from the center of circulation.

Tropical Cyclone Damien will move through an environment favorable for intensification during the next 24 hours.  Damien will move over water where the Sea Surface Temperature is near 30°C.  It will move under the western end of an upper level ridge over Australia.  The ridge will produce northeasterly winds which will blow toward the top of the circulation.  Those winds will cause some vertical wind shear, but the shear will not be strong enough to prevent intensification.  Tropical Cyclone Damien will strengthen during the next 24 hours and it could rapidly intensify into the equivalent of a major hurricane.

Tropical Cyclone Damien will move around the western end of a high pressure system centered over Australia.  The high will steer Damien toward the south during the next 24 hours.  On its anticipated track the center of Tropical Cyclone Damien could make landfall on the coast of Western Australia in the vicinity of Dampier, Karratha and Wickham in about 24 hours.  Damien could be the equivalent of a major hurricane when it reaches the coast.  It will produce strong gusty winds.  Tropical Cyclone Damien will also drop locally heavy rain and flash floods could occur in some locations.

Elsewhere over the South Indian Ocean, Tropical Cyclone Francisco weakened east of Rodrigues.  At 4:00 a.m. EST on Thursday the center of Tropical Cyclone Francisco was located at latitude 19.3°S and longitude 71.7°E which put it about 565 miles (910 km) east of Port Mathurin, Mauritius.  Francisco was moving toward the southeast at 13 m.p.h. (20 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 1001 mb

Tropical Cyclone Develops Near Western Australia, Watch Issued

A tropical cyclone currently designated as 14S (SH14) developed near the coast of Western Australia on Wednesday and a Watch was issued for a portion of the coast.  At 10:00 p.m. EST on Wednesday the center of Tropical Cyclone 14S was located at latitude 17.1°S and longitude 120.2°E which put it about 250 miles (400 km) north-northeast of Port Hedland, Australia.  The tropical cyclone was moving toward the west-southwest at 10 m.p.h. (16 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 998 mb.  A Watch was issued for a portion of the coast of Western Australia from Wallal Downs to Onslow including Port Hedland, Karratha and Dampier.

A Tropical Low previously located over Western Australia moved westward over the South Indian Ocean on Wednesday and it strengthened into Tropical Cyclone 14S.  The circulation around the tropical cyclone was still organizing on Wednesday night.  More thunderstorms were forming near the center of circulation.  Bands of showers and thunderstorms were developing and the bands were revolving around the center of the tropical cyclone.  Storms near the center began to generate upper level divergence which was pumping mass away from the tropical cyclone.

Tropical Cyclone 14S will move through an environment favorable for intensification during the next 48 hours.  The tropical cyclone will move over water where the Sea Surface Temperature is near 30°C.  It will move under the northwestern part of an upper level ridge centered over northern Australia.  The ridge will produce easterly winds which will blow toward the top of the circulation.  Those winds will cause moderate vertical wind shear, but the shear will not be strong enough to prevent intensification.  Tropical Cyclone 14S will continue to intensify and it could strengthen into the equivalent of a hurricane/typhoon in 24 to 36 hours.

Tropical Cyclone 14S will move around the northwestern end of a high pressure system over Australia.  The high will steer the tropical cyclone toward the west-southwest during the next 12 to 24 hours.  Tropical Cyclone 14S will turn more toward the south on Friday when it reaches the western end of the high pressure system.  On its anticipated track Tropical Cyclone 14S could approach the coast of Western Australia between Port Hedland and Karratha in about 48 hours.  It will likely be the equivalent of a hurricane/typhoon when it approaches the coast.

Elsewhere over the South Indian Ocean, Tropical Cyclone Francisco formed northeast of Rodrigues.  At 4:00 p.m. EST on Wednesday the center of Tropical Cyclone Francisco was located at latitude 17.8°S and longitude 70.4°E which put it about 485 miles (785 km) east-northeast of Port Mathurin, Mauritius.  Francisco was moving toward the east-southeast 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 998 mb.

Tropical Cyclone Blake Makes Another Landfall in Western Australia

Tropical Cyclone Blake made another landfall on the coast of Western Australia on Tuesday.  At 4:00 p.m. EST on Tuesday the center of Tropical Cyclone Blake was located at latitude 20.1°S and longitude 120.5°E which put it about 20 miles (35 km) south-southwest of Wallal Downs, Australia.  Blake was moving toward the southwest at 6 m.p.h. (10 km/h).  The maximum sustained wind speed was 45 m.p.h. (75 km/h) and there were wind gusts to 55 m.p.h. (90 km/h).  The minimum surface pressure was 990 mb.

The center of Tropical Cyclone Blake moved across the coast of Western Australia just to the west of Wallal Downs on Tuesday.  Blake was beginning to weaken, but winds to tropical storm force were still occurring in the northwestern part of the circulation that was still over water.  A weather station at Bedout Island which is just off the coast of Western Australia was reporting a sustained wind speed of 43 m.p.h. (69 km/h) and wind gusts to 50 m.p.h. (82 km/h).  A weather station in Mandora, Australia had already received 2.69 inches (64.4 mm) of rain from the rainbands in eastern side of the tropical cyclone.

Tropical Cyclone Blake will move around the western end of a high pressure system over Australia.  Blake will move more toward the south when it reaches the western end of the high.  On its anticipated track the center of Tropical Cyclone Blake could be near Marble Bar in about 12 hours.  Blake could approach Newman in about 24 hours.  Tropical Cyclone Blake will weaken as it moves farther inland.  Blake could drop locally heavy rain over parts of Western Australia and the potential for flash floods exists.

Elsewhere, a Tropical Low was slowly organizing over the Arafura Sea north of Australia.  At 1:00 p.m. EST on Tuesday the center of the Tropical Low was located at latitude 11.2°S and longitude 137.7°E which put it about 70 miles (115 km) north-northeast of Nhulunbuy, Australia.  The Tropical Low was moving toward the west at 3 m.p.h. (5 km/h).  The maximum sustained wind speed was 30 m.p.h. (50 km/h) and there were wind gusts to 40 m.p.h. (65 km/h).  The minimum surface pressure was 1003 mb.  The Tropical Low is forecast to move westward and to strengthen.  A Watch has been issued for the portions of the coast from Cape Don to Point Stuart and from Goulburn Island to Cape Shield.

Tropical Cyclone Blake Brings Wind and Rain to Western Australia

Tropical Cyclone Blake brought wind and rain to portions of Western Australia on Monday.  At 10:00 p.m. EST on Monday the center of Tropical Cyclone Blake was located at latitude 18.7°S and longitude 121.5°E which put it about 60 miles (95 km) southwest of Broome, Australia.  Blake was moving toward the south-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 989 mb.

The center of Tropical Cyclone Blake made landfall on the coast of Western Australia north of Broome earlier on Monday.  The center moved back out over water slightly north of Broome and then the center passed just to the west of that city.  A weather station in Broome measured sustained winds of 30 m.p.h. (50 km/h) and a wind gust to 50 m.p.h. (82 km/h).  5.83 inches (148 mm) of rain fell over Broome.  A rainband in the northeastern periphery of the circulation dropped rain over the area around the Kimberly Plateau during much of Monday.

Tropical Cyclone Blake weakened while the center was over land, but it appears to be strengthening again now that the center is back over water.  More thunderstorms developed near the center of circulation during the past few hours.  Those storms started to generated upper level divergence again.  Bands farther away from the center consisted primarily of showers and lower clouds.  Winds to tropical storm force extended out about 100 miles (160 km) from the center of circulation mainly in portions of circulation over water.

Tropical Cyclone Blake will move through an environment favorable for intensification during the next 12 hours.  Blake will move over water where the Sea Surface Temperature is near 29°C.  It will move through a region where the upper level winds are weak and there will be little vertical wind shear.  Tropical Cyclone Blake could strengthen during the next 12 hours.

Tropical Cyclone Blake will move around the western end of a high pressure system over Australia.  The high will steer Blake toward the south-southwest during the next 24 to 36 hours.  On its anticipated track Tropical Cyclone Blake could make another landfall on the coast of Western Australia near Wallal Downs.  A Warning is in effect for the portion of the coast from Bidyadanga to De Grey.  Blake will bring gusty winds and rain to that portion of the coast.

Elsewhere, a new Tropical Low developed over the Arafura Sea north of Australia.  At 8:00 p.m. EST on Monday the center of the Tropical Low was located at latitude 10.7°S and longitude 137.7°E which put it about 120 miles (195 km) north-northeast of Nhulunbuy, Australia.  The Tropical Low was moving toward the east at 6 m.p.h. (9 km/h).  The maximum sustained wind speed was 30 m.p.h. (50 km/h) and there were wind gusts to 40 m.p.h. (65 km/h).  The minimum surface pressure was 1003 mb.  The Tropical Low is forecast to move back toward the west and to strengthen.  A Watch has been issued for the portion of the Australian coast from Cape Shield to Cape Don including Goulburn Island.  On its anticipated track the center of the Tropical Low could pass near Cape Wessel in about 24 hours.

Tropical Cyclone Blake Strengthens Near Western Australia

Tropical Cyclone Blake strengthened near Western Australia on Sunday.  At 10:00 p.m. EST on Sunday the center of Tropical Cyclone Blake was located at latitude 16.1°S and longitude 121.9°E which put it about 140 miles (220 km) north of Broome, Australia.  Blake was moving toward the east-southeast 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 995 mb.

A Warning has been issued for the portion of the coast of Western Australia from Kuri Bay to De Grey including Broome.  A Watch has been issued for the portion of the coast from De Grey to Whims Creek including Port Hedland.

The circulation around a Tropical Low over the South Indian Ocean northwest of Australia became more organized on Sunday night and the Australian Bureau of Meteorology designated the system as Tropical Cyclone Blake.  The inner end of a rainband wrapped around the southern and western sides of the center of circulation.  Storms near the center of circulation began to generate upper level divergence which pumped mass away from the tropical cyclone.  Many of the thunderstorms were occurring in a primary rainband on the eastern side of Blake.  Bands in other parts of the circulation consisted primarily of showers and lower clouds.  Winds to tropical storm force extended out 150 miles (240 km) from the center of circulation.

Tropical Cyclone Blake will move through an environment favorable for intensification during the next 24 to 36 hours.  Blake will move over water where the Sea Surface Temperature is near 30°C.  It will move through a region where the upper level winds are weak and there will be little vertical wind shear.  Tropical Cyclone Blake will continue to intensify and it could strengthen into the equivalent of a hurricane/typhoon.

The center of Tropical Cyclone Blake shifted eastward on Sunday as the circulation reorganized closer to the inner end of the primary rainband.  Blake will move around the western end of a high pressure system centered near northern Australia.  The high will steer Blake toward the south-southwest.  On its anticipated track the center of Tropical Cyclone Blake will pass just west of Broome in about 24 hours.  Blake could make landfall on the coast of Western Australia near Wallal Downs in about 36 hours.  Tropical Cyclone Blake will bring gusty winds and locally heavy rain to the coast of Western Australia.
