Weekly rainfall wrap + rain outlook, 12 Feb 2020

Bureau of Meteorology, February 12, 2020


Tropical Cyclone Damien brought moderate to heavy rainfall to the northwest of Australia, and thunderstorms produced widespread showers and rain areas along the east Australian coast.

Past seven days: At the start of the week, a tropical low pressure system was located near the coast of the western Kimberley district of Western Australia. A weak monsoon trough extended across Cape York Peninsula and the Gulf of Carpentaria and over the Top End, with showers and thunderstorms across the far north. A trough positioned across inland Queensland and New South Wales produced isolated storms.

In the first half of the week, tropical cyclone Damien developed offshore north of Port Headland, in northwest Western Australia, and continued to move southwest intensifying to a severe tropical cyclone. Across northern Australia a chain of thunderstorms, associated with the monsoon trough, extended  towards the northern Coral Sea, while an influx of moist air from the Coral Sea produced a showers and storms which extended from northern Queensland through to Victoria. A slow-moving coastal trough over the southeast of Queensland and northern New South Wales resulted in showers, extensive areas of rain and heavy falls.

In the second half of the week, tropical cyclone Damien started to move towards the coast; it made landfall near Dampier as a category 3 system, then weakened to tropical low while moving through inland Pilbara and central Western Australia producing heavy rain. A weak monsoon though across central parts of the Northern Territory and northern Queensland produced scattered showers and isolated thunderstorms. A coastal trough positioned parallel to the east Australian coast strengthened, maintaining widespread showers and rain areas across southeastern Queensland and eastern New South Wales, before moving south and weakening.

Rainfall totals in excess of 200 mm were recorded in southeast Queensland, in eastern New South Wales, and around Port Headland in northwest Western Australia.

Rainfall totals in excess of 100 mm were recorded in the northern part of Cape York Peninsula, and southeast Queensland, most of eastern New South Wales, in isolated areas across the Top End in the Northern Territory, and in parts of Pilbara, West Gascoyne and  in isolated pockets in the north of Western Australia.

Rainfall totals in excess of 50 mm were recorded in areas surrounding higher falls, and in the northeast of Victoria.

Rainfall totals between 10 and 50 mm were recorded in East Gascoyne, Central and parts of Southeast and South Coastal districts and areas in the north of Western Australia, in southeast South Australia, parts of the Northern Territory, large areas mostly in northeastern and central Queensland, parts of central New South Wales, most of northern Victoria, and eastern Tasmania.
