Track of TC 20P

Tropical Depression Tim (20P) is tracking southeastward under the influence of the mid-level NER to the north. After TAU 36, this steering mechanism is expected to weaken and be gradually replaced by a deep layer subtropical ridge (STR) to the southeast, which is expected to build in behind Tropical Cyclone Sandra (19P).

Storm motion will slow as the steering transition takes place, allowing for further intensification, to a peak of 75 knots. Around TAU 72, the building STR will deflect Tim westward, back toward the Australian coast. Increasing VWS after TAU 72 should start to gradually weaken the system. Maximum significant wave height is 12 feet.
