Cold front bringing strong winds, rain and the odd storm to southern WA

Sam Brown, Sunday September 6, 2020 - 14:07 AEST


A cold front crossing southern parts of Western Australia on Sunday is causing gusty winds, rain and the odd thunderstorm to develop.


Manjimup and Witchcliffe in the South West district have already picked up 22.4mm and 18.4mm respectively since 9am WST. Northwesterly and westerly wind gusts have reached 87km/h at Albany airport, 91km/h at Cape Leeuwin, 89km/h at Busselton Jetty and 72km/h at Rottnest Island as of 11:50am WST.


24-hour rainfall totals potentially may reach in excess of 30mm from Sunday to Monday morning, with the highest totals expected around Walpole and Albany. In general, areas south of a line from about Denham to about Israelite Bay may see at least a few millimetres of rain from this system.

Winds will tend more westerly on Sunday afternoon and evening in the wake of the front, although continuing in strength. Gusts in excess of 80km/h are expected well into Monday morning in exposed coastal areas in the southwest, while spreading inland.


Isolated thunderstorms are also a chance with the passage of this system. However, there is a higher chance on Monday morning in the far south from about Augusta to Albany. 


Daytime temperatures will also drop across the region on Monday with cold air in the system's wake. Inland areas will feel the largest difference, with Kalgoorlie potentially dropping 10-12 degrees below Sunday's maximum of around 33.


Hot and dry northwesterly winds ahead of the front are also leading to a Catastrophic Fire Danger warning for the Eucla district, and a Severe Fire Danger warning to the Gascoyne Inland, Goldfields and South Interior districts.


Conditions will ease later on Monday as high pressure builds bringing a few colder than average mornings from Tuesday.

A very wet weekend for southeast Qld, northeast NSW

11:48 AEST A prolonged rainfall event is set to bring large totals to parts of NSW and Qld from Saturday, with possible heavy falls and flooding.  A low-pressure system in the Coral Sea, a deepening coastal trough and persistent easterlies will bring moisture-laden air into southeast Qld and northeast NSW will bring days of rainfall to the region.  While there is not a drop of rain on the radar over southeast Qld and Northeast NSW on Friday morning, the mass of cloud associated with a low in the Coral Sea will enhance rainfall over the weekend.
