This could be interesting if it manages to keep itself from running aground over Australia, but my current thinking is the land interaction will limit it, much like several of the systems earlier this season.

I think it's far enough from Australia to develop. Atm, its satellite signature looks pretty nice.

REMARKS:
The centre was located using animated Visible satellite imagery. Satellite
depicts an exposed small, tight vortex close to the deep convection moving in a
southerly direction.

Dvorak intensity at 00Z is based a shear pattern averaged over 3h giving a
DT=2.0. MET is not available. Max winds set at 25kt.

The low is in a region of high 20-30kt ESE wind shear based on CIMSS. The upper
ridge is located further south and is providing good upper diffluence and
allowing the convection to develop to the W of the LLCC.

The low is expected to move S to SW during the next 2-3 days placing the low in
a more favourable shear environment. Intensity forecast is based on a standard
development rate with TC strength expected by 00Z on 5 March.

Tropical Low crossing the Tiwi Islands. Tropical Cyclone may form later this morning.


Areas affected:

Warning zone: Point Stuart to Wadeye, including Darwin, Tiwi Islands and Wadeye.

Watch zone: Kuri Bay to Wadeye.

Cancelled zones: Cape Don to Croker Island.


Details of Tropical Low at 5:00 am AWST:

Intensity: tropical low, sustained winds near the centre of 55 kilometres per hour with wind gusts to 85 kilometres per hour.
Location: within 55 kilometres of 11.7 degrees South, 130.6 degrees East , 30 kilometres south southwest of Milikapiti and 85 kilometres north northwest of Darwin .
Movement: south southwest at 17 kilometres per hour .

The tropical low is currently passing over the Tiwi Islands at below tropical cyclone intensity. The tropical low is continuing to intensify and may reach tropical cyclone intensity later this morning or afternoon, offshore from the northwest Top End coast. The system is expected to continue tracking to the southwest and intensify further, crossing the north Kimberley coast later on Monday as a Category 2 system.


Hazards:

GALES with gusts to 110 kilometres per hour may develop about the Tiwi Islands later this morning. GALES may develop between Point Stuart and Daly River Mouth, including Darwin from early this afternoon, and extend south to Wadeye (Port Keats) later Sunday or early Monday.

GALES may develop between Wadeye (Port Keats) and Kuri Bay during Monday.

Tides will be HIGHER THAN NORMAL between Point Stuart in the NT and Kuri Bay in WA today and Monday. Large waves may produce MINOR FLOODING of low-lying coastal areas.

HEAVY RAIN and SQUALLS are likely to continue over the Tiwi Islands and northwestern Top End, extending to the southwestern Top End later today and to the Kimberley region tonight or Monday.

DAMAGING WIND GUSTS are possible in squally showers and storms across the northwest Top End during the next day or two even if the low does not reach cyclone intensity.
