7 day weather forecast

     Effective as of 4:00 PM Tuesday June 8 2021

Explanatory notes:

Plenty of high and middle level clouds associated with tropical moisture aloft streaming from the strengthening subtropical low pressure system over the Indian Ocean ahead of an upper level trough.

At 4:10 PM, surface observations indicate the formation of a rotor near the foothills. There were strong easterlies flowing down the Hills but winds were from a westerly direction at Millendon (Swan Valley).

The subtropical low pressure system strengthens with the strong upper level divergence and moves to the southeast to lies to the west of the region on Wednesday leading to strong gusty winds and possible raised dust if rain doesn't moisten soils sufficiently. The most likely scenario is first some rain, elevated showers and possibly thunderstorms in the morning with upper level divergence ahead of the upper level trough, then another round of showers overnight associated with an area of low level wind convergence followed by moist onshore flow.

The Australian Bureau of Meteorology (BOM) has issued a severe weather warning for damaging winds, abnormally high tides and damaging surf for the southwest of the state including Mandurah. View the latest warning at http://www.bom.gov.au/products/IDW21037.shtml .
