Tropical Cyclone “Lincoln” hits Gulf of Carpentaria, heavy rainfall and damaging winds continue, Australia

Tropical Cyclone “Lincoln” made landfall on the Gulf of Carpentaria coast between Port McAarthur and the Northern Territory – Queensland border at 06:00 UTC on February 16, 2024, as a Category 1 storm. Shortly after, it weakened and moved west across the Northern Territory, with heavy rainfall forecasted and a moderate risk of redeveloping into a tropical cyclone.

After making landfall as a Category 1 cyclone on the Australian scale, Lincoln quickly weakened below cyclone intensity near Borroloola.

Despite its downgrade, the system’s remnants continue to pose significant weather threats as they move across the central Northern Territory and towards the Kimberley region in Western Australia. Heavy rainfall, potentially leading to flash flooding and minor river flooding, is expected along its path.

As of February 17, 2024, at 02:10 UTC, Lincoln’s remnants were over the Barkly District, moving towards the northern Tanami and southern Gregory Districts. The Severe Weather Warning forecasts heavy to locally intense rainfall, with totals ranging from 70 – 120 mm (2.76 – 4.72 inches) and isolated heavier falls up to 180 mm (7.09 inches) possible.

Strong winds averaging 50 to 60 km/h (31 to 37 mph) with gusts up to 90 km/h (56 mph) are also anticipated.

The Flood Watch highlights the vulnerability of catchments already saturated from recent rains. Significant rises in rivers, creeks, and streams are anticipated, with minor flooding a possibility in affected areas. The Daly River catchment is currently under a moderate flood warning.

Authorities have issued severe weather advisories, urging residents to secure loose items, avoid unnecessary travel, and prepare for potential isolation due to flooded roads and waterways. Emergency services are on standby for storm and flood response, emphasizing the need for community preparedness and caution.

As Lincoln’s remnants progress, they carry a moderate risk of redeveloping into a tropical cyclone by mid-next week, potentially impacting waters west of the Kimberley and north of the Pilbara.
