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. The tropical cyclone was moving toward the southeast 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.
