Tropical Cyclone Seroja Brings Wind and Rain to Western Australia

Tropical Cyclone Seroja brought wind and rain to Western Australia on Sunday. At 8:00 a.m. EDT on Sunday the center of Tropical Cyclone Seroja was located at latitude 28.1°S and longitude 114.3°E which put it about 30 miles (45 km) south-southeast of Kalbarri, Australia. Seroja was moving toward the southeast at 26 m.p.h. (43 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). The minimum surface pressure was 976 mb.

A Tropical Cyclone Warning was in effect from Overlander Roadhouse to Lancelin. The Warning extended inland to Merredin.

Tropical Cyclone Seroja made landfall on the coast of Western Australia between Kalbarri and Geraldton. Seroja strengthened to the equivalent of a hurricane/typhoon before it made landfall. The airport at Geraldton was reporting sustained winds to 56 m.p.h. (91 km/h) and wind gusts to 75 m.p.h. (120 km/h) as the center of Tropical Cyclone Seroja approached the station.

Tropical Cyclone Seroja will move rapidly across the southwestern part of Western Australia during the next 24 hours. Seroja will bring gusty winds and it will drop locally heavy rain over parts of Western Australia. Flood Watches have been issued for the Wooramel, Murchison, Greenough, Yarra Yarra Lakes, Avon River and parts of the Salt Lake Catchments.

Tropical Cyclone Seroja Turns Toward Western Australia

Tropical Cyclone Seroja turned toward the coast of Western Australia on Saturday. At 5:00 p.m. EDT on Saturday the center of Tropical Cyclone Seroja was located at latitude 23.2°S and longitude 110.2°E which put it about 435 miles (700 km) northwest of Kalbarri, Australia. Seroja was moving toward the southeast at 12 m.p.h. (19 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 Tropical Cyclone Warning was in effect from Minilya Roadhouse to Lancelin, Australia. The Warning included Cape Cuvier, Carnavon, Denham, Kalbarri, Jurien Bay and Lancelin.

Tropical Cyclone Seroja intensified to the equivalent of a hurricane/typhoon after it turned toward the coast of Western Australia on Saturday. The inner end of a rainband wrapped around the center of Seroja and microwave satellite images showed evidence of the formation of an eye. The strongest thunderstorms were occurring in bands in the eastern half of Tropical Cyclone Seroja. Bands in the western half of the circulation consisted primarily of showers and lower clouds. Storms near the center of Seroja generated upper level divergence that pumped mass away to the southeast of the tropical cyclone. Winds to hurricane/typhoon force extended out 30 miles (50 km) from the center of Tropical Cyclone Seroja. Winds to tropical storm force extended out 125 miles (200 km) from the center of circulation.

Tropical Cyclone Seroja will move through an environment favorable for intensification during the next 12 hours. Seroja will move over water where the Sea Surface Temperatures will be near 29°C. An upper level trough over the South Indian Ocean will produce northwesterly winds which will blow toward the top of Seroja. Those winds will cause moderate vertical wind shear. The wind shear will limit intensification, but Tropical Cyclone Seroja could get a little stronger during the next 12 hours. Seroja will begin to weaken when it moves over Western Australia.

The upper level trough over the South Indian Ocean will steer Tropical Cyclone Seroja toward the southeast during the next 36 hours. On its anticipated track the center of Tropical Cyclone Seroja will pass just to the west of Denham during the next 12 hours. Seroja make landfall on the coast of Western Australia near Kalbarri in 15 hours. Tropical Cyclone Seroja will move across the southwestern part of Western Australia after it makes landfall.

Tropical Cyclone Seroja will bring produce winds to hurricane/typhoon force to the portion of the coast near Kalbarri. Winds to tropical storm force could occur along the portion of the coast from Denham to Geraldton. Wind blowing water toward the coast could cause a storm surge of up to 7 feet (2 meters) near where the center makes landfall. Tropical Cyclone Seroja will drop locally heavy rain over parts of Western Australia. Flood Watches have been issued for the Wooramel, Murchison, Greenough, Yarra Yarra Lakes, Avon River and parts of the Salt Lake Catchments.

Tropical Cyclone Seroja Spins Northwest of Australia

Tropical Cyclone Seroja was spinning northwest of Australia on Wednesday night. At 11:00 p.m. EDT on Wednesday the center of Tropical Cyclone Seroja was located at latitude 16.0°S and longitude 113.4°E which put it about 410 miles (665 km) north of Exmouth, Australia. Seroja was moving toward the west-southwest at 8 m.p.h. (13 km/h). The maximum sustained wind speed was 65 m.p.h. (105 km/h) and there were wind gusts to 80 m.p.h. (130 km/h). The minimum surface pressure was 985 mb.

Tropical Cyclone Seroja was exhibiting signs of intensification on Wednesday night, but it was also still being affected by vertical wind shear. More thunderstorms were beginning to form near the center of circulation. However, the distribution of thunderstorms was asymmetrical. Many of the stronger thunderstorms were occurring in bands in the western half of Seroja. Bands in the eastern half of the circulation consisted primarily of showers and lower clouds. Winds to tropical storm force extended out 100 miles (160 km) from the center of circulation.

Tropical Cyclone Seroja will move through an environment more favorable for intensification during the next several days. Seroja will move over water where the Sea Surface Temperatures will be near 30°C. It will move under the northwestern part of an upper level ridge centered over northwestern Australia during the next 24 hours. The ridge will produce northeasterly winds which will blow toward the top of the circulation. Those winds will cause some vertical wind shear. Tropical Cyclone Seroja could intensify gradually during the next 24 hours. Seroja will move closer to the axis of the upper level ridge in a day or so. The winds are weaker near the axis of the ridge and the wind shear will decrease. Tropical Cyclone Seroja could strengthen into the equivalent of a hurricane/typhoon during the next 36 hours. Seroja could strengthen more rapidly when the vertical wind shear decreases and it is forecast to intensify into the equivalent of a major hurricane.

Tropical Cyclone Seroja will move around the northwestern part of a high pressure system over Australia. The high will steer Seroja toward the southwest during the next 48 hours. On its anticipated track Tropical Cyclone Seroja will remain northwest of Western Australia during the next two days. An upper level trough over the South Indian Ocean will approach Seroja during the weekend. The trough will turn Tropical Cyclone Seroja toward the southeast and it could approach the coast of Western Australia south of Denham in 72 hours.

Elsewhere over the South Indian Ocean, Tropical Cyclone 27S was interacting with the western side of Tropical Cyclone Seroja. At 11:00 p.m. EDT on Wednesday the center of Tropical Cyclone 27S was located at latitude 15.8°S and longitude 105.9°E which put it about 645 miles (1040 km) northwest of Exmouth, Australia. The tropical cyclone was moving toward the northeast at 4 m.p.h. (6 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 994 mb.

Tropical Cyclone Seroja Moves away from Indonesia

Tropical Cyclone Seroja moved slowly away to the south of Indonesia on Monday. At 11:00 p.m. EDT on Monday the center of Tropical Cyclone Seroja was located at latitude 11.7°S and longitude 119.8°E which put it about 460 miles (740 km) north-northwest of Broome, Australia. Seroja was moving toward the west-southwest at 8 m.p.h. (13 km/h). The maximum sustained wind speed was 65 m.p.h. (105 km/h) and there were wind gusts to 80 m.p.h. (130 km/h). The minimum surface pressure was 985 mb.

After dropping heavy rain over parts of eastern Indonesia and causing flash floods and mudslides, Tropical Cyclone Seroja moved slowly away from the area on Monday. The circulation around Seroja appeared to be a little stronger on Monday night. Bands of showers and thunderstorms were revolving around a well defined low level center of circulation. Storms near the center generated upper level divergence that pumped mass away to the west of the tropical cyclone. Winds to tropical storms force extended out 100 miles (160 km) from the center of circulation.

Tropical Cyclone Seroja will move through an environment somewhat favorable for intensification during the next several days. Seroja will move over water where the Sea Surface Temperatures will be near 30°C. It will move under the northern part of an upper level ridge centered over northwestern Australia. The ridge will produce easterly winds which will blow toward the top of the circulation. Those winds will cause moderate vertical wind shear. Tropical Cyclone Seroja could intensify gradually during the next 48 hours. Seroja could strengthen into the equivalent of a hurricane/typhoon during the next several days. The wind shear will decrease later this week and Tropical Cyclone Seroja could strengthen more rapidly when that occurs.

Tropical Cyclone Seroja will move around the northwestern part of a high pressure system over Australia. The high will Seroja toward the southwest during the next 48 hours. On its anticipated track Tropical Cyclone Seroja will remain northwest of Western Australia during the next two days. An upper level trough over the South Indian Ocean will approach Seroja later this week. The trough could turn Tropical Cyclone Seroja toward the southeast and it could eventually threaten Western Australia.

Elsewhere over the South Indian Ocean, Tropical Cyclone 27S churned south of Christmas Island. At 11:00 p.m. EDT on Monday the center of Tropical Cyclone 27S was located at latitude 16.3°S and longitude 105.5°E which put it about 700 miles (1100 km) northwest of Learmonth, Australia.
