TROPICAL CYCLONE INFORMATION BULLETIN
Issued at 2:41 pm WST on Sunday 14 December 2025


Severe Tropical Cyclone Bakung (Category 3) was located at 2:00 pm AWST (12:30
pm CCT) near 10.3S 91.0E,
that is 670 km west northwest of Cocos (Keeling) Islands and moving west
southwest at 11 kilometres per hour.

Severe Tropical Cyclone Bakung (05U) was named by Jakarta, Indonesia, on Friday
night. Bakung intensified rapidly as it moved into the Australian area of
responsibility last night but has recently shown signs of weakening. It is
expected to continue weakening tonight and on Monday.

Bakung has been moving towards the west-southwest but is beginning to slow down
as it interacts with a second tropical low further northeast. Bakung may turn
back towards the east tomorrow, but uncertainty in its future movement is high.

Bakung is expected to remain far enough northwest of the Cocos (Keeling)
Islands for no direct impacts to occur. However, there is a small chance Bakung
could move closer to the Cocos (Keeling) Islands during the week. Residents on
the Cocos (Keeling) Islands should keep up-to-date with the latest forecasts.

The next Information Bulletin will be issued at 9:00 pm AWST Sunday 14 December
(7:30 pm CCT Sunday 14 December).

17DEC25. TROPICAL CYCLONE 07S (BAKUNG), LOCATED APPROXIMATELY 331
NM WEST?NORTHWEST OF THE COCOS ISLANDS, HAS TRACKED NORTH?
NORTHWESTWARD AT 05 KNOTS OVER THE PAST SIX HOURS. ANIMATED ENHANCED
INFRARED SATELLITE IMAGERY DEPICTS 07S WITH A DECOUPLED  LOW-LEVEL
CIRCULATION CENTER (LLCC) THAT IS DISPLACED FAR TO THE NORTHWEST OF
THE DEEP CONVECTION. A 171533Z METOP-B ASCAT PASS REVEALED A HIGHLY
ASYMMETRIC WIND FIELD WITH WINDS OF 25-30 KTS CONFINED TO THE
SOUTHERN SEMICIRCLE. WINDS WITHIN THE NORTHERN PERIPHERY OF THE LLCC
ARE MUCH LOWER, AT AROUND 10-15 KTS. ENVIRONMENTAL ANALYSIS
INDICATES THAT 07S IS IN AN UNFAVORABLE ENVIRONMENT CHARACTERIZED
BY WEAK POLEWARD OUTFLOW, HIGH (25-30 KTS) NORTHEASTERLY VERTICAL
WIND SHEAR, AND SIGNIFICANT DRY AIR ENTRAINMENT. 07S IS FORECAST TO
TRACK GENERALLY NORTHWESTWARD OVER THE NEXT 24 HOURS AND THE HOSTILE
ENVIRONMENT IS EXPECTED TO CAUSE GRADUAL WEAKENING. THIS IS THE
FINAL WARNING ON THIS SYSTEM BY THE JOINT TYPHOON WRNCEN PEARL
HARBOR HI. THE SYSTEM WILL BE CLOSELY MONITORED FOR SIGNS OF
REGENERATION. MINIMUM CENTRAL PRESSURE AT 171800Z IS 1004 MB.
