Weather News - Wild weather on the way for Victoria and TasmaniaCraig McIntosh, 30 April 2016
As a deep low and cold front approaches Australia's southeast, Victoria and Tasmania are preparing for the brunt of the nasty weather.
As a prelude to what's coming, parts of Victoria are already feeling strong wind gusts. Mount Gellibrand and Mount William have both recorded gusts of 63km/h this morning. A strong wind warning is currently in place for the West Coast. Melbourne is not escaping the wind either, with gusts up to 52km/h felt at the airport just before 11am.
Western Tasmania is in the same boat as their northern neighbour, with Low Rocky Point and Mount Read both recording gusts of 63km/h. Over in the east, Hobart clocked a gust of 33km/h, while Mount Wellington blew the opposition away with the strongest recorded gust so far at 76km/h. A strong wind warning for the Southwest and Central West coasts is in effect, alongside a Small Craft Alert for the South West Lakes.
So far the rain has mostly held off, however that will change throughout today and into tomorrow.
Victoria has the potential for widespread thunderstorms overnight and into tomorrow. They will most likely spark up in the Mallee and track east throughout the day. These storms may bring damaging winds and heavy rain.
Tasmania will be battening down the hatches tomorrow with a Storm Force Wind Warning issued in advance for the Lower East and South East Coasts. This means sustained winds of over 85km/h with potential gusts over 120km/h. A Gale Warning has also been issued in advance for all remaining coasts, including the Derwent Estuary and Hobart Waters.

Weather News - Red sky in the morning, shepherd's warningGuy Dixon, 29 April 2016
Sydney-siders were graced with a beautiful sunrise this morning, a hue of orange and pink to start the end of the week.
The old saying, "Red sky in the morning, shepherd's warning, red sky at night, shepherd's delight." actually has quite a bit of science behind it.
Today, conditions were primed with relatively poor air quality due to hazard reduction burns in the area and the perfect synoptic setup.
Usually, as a low pressure trough approaches from the west, a high pressure ridge will be residing to the east. Often an inversion can be found under areas of high pressure, a phenomenon where warm air rests on top of cold air. This is exactly what happened today.
As the pollutants in the air collected within this inversion, the morning sun shining through created a beautiful array of warm colours.
Ultimately, as the low pressure trough continues to bare down along its eastward movement, conditions will often deteriorate with wind, cloud and showers threatening, hence the shepherds and sailors warning each other.
This old saying is likely to prove itself correct once again with showers developing just in time for the weekend for Sydney, including much of NSW and the nation's southeast.

Weather News - Cyclone season wrap-upGuy Dixon, 30 April 2016
Today marks the final day of Australia's tropical cyclone season, and it has been an absolute fizzer.
Coupled with one of the strongest El Nino events on record, Australia has seen it's quietest cyclone season on record, with only three systems within the Australian region - Stan, Tatiana and Uriah.
Severe Tropical Cyclone Winston stands out as a significant system of the season, but actually falls under the jurisdiction of Fiji, despite later impacting the Tropical coast of QLD as a tropical low.
On average, we usually observe 11 cyclones within the Australian region but the impacts of a strong El Nino event typically reduces the number of systems that develop and can hamper the chances of coastal crossings, particularly in QLD by up to 50%.
Stan was the only system to make landfall, keeping the 46 year tradition alive with at least one coastal crossing per season.
A delayed onset of the monsoon season and development of initial systems is also often observed, with El Nino seasons usually kicking off between 2-6 weeks later than a La Nina season.
Instead, the more favourable conditions were positioned further east over the Central and South Pacific Ocean.
