DAMAGING WINDS RETURN FOR SOUTHEAST AUSTRALIA TUESDAY

Another belt of strong and gusty northwest winds are expected to descend across SA during Tuesday, into western and central VIC during Tuesday afternoon and evening and over Alpine VIC and NSW through elevated southeastern NSW on Wednesday morning.


The winds will drag in a milder day, but that warmer air clashing with the colder air are typical for this time of year and lead to land gales as we head through August and September which is the windiest time of the year.


The winds will ease later Wednesday but may return again on Friday.


Damaging Winds Forecast Risk for Tuesday.

Damaging winds are expected to develop ahead of a cold front. That cold front will bring a tightening pressure gradient over the southeast causing a strong northwest wind flow to form. Winds average 50-60km/h with gusts to 90km/h are possible. Above about 800m in the southeast states, winds may exceed 120km/h. The winds will ease behind the front below warning strength during Wednesday from west to east.

18Z GFS - Wind Gust Swathe for the coming 3 days. Note there are wind gusts of up to 80kmh through vast areas of inland SA and NSW extending southeast. This model smooths out the wind gusts, but clearly over elevation there will be winds over 100kmh with peak gusts closer to 120kmh over Alpine areas later Tuesday through Wednesday.

Tree damage is still a high risk through elevated VIC after the significant storm of June. Those trees remain unstable in the rural and regional settings so be aware of the high risk of fallen trees once again during this week.


There is another risk of gale force winds later this week.
