Significant rainfall, strong winds, strong wind gusts and abnormally high and low temperatures for this day are given below. Descriptions
of significant weather events are added here when time permits and reliable information is available. This is sometimes well after the event!
A severe storm that travelled from around Gunning NSW to the southwestern
edge of the Sydney metro area today has been well documented by Andrew Miskelly
here. A severe downburst funnelled down a valley caused massive tree damage
to the north of Taralga.
On the 17th at Bathurst (Central Tablelands) strong winds caused damage
to structures. At Kempsey (Mid North Coast) very heavy rain fell.
On the 16th and 17th a combination of unusually
high surface moisture, a surface trough and mid-level trough produced
many severe thunderstorms resulting in mainly heavy rain and localised
flooding in many parts of southern Western Australia. There were reports
of some unofficial sites recording well over 100 mm.
Some significant daily totals included Cuttening
95 mm, Bridgetown 91 mm, Gairdner 85 mm and Corrigin 76 mm. Although many
farmers welcomed the rains, flooding caused considerable damage mainly
to roads and fences.
At Gin Gin power lines were brought down, large redgums uprooted and
other trees snapped off 3 metres from the base on the 16th. A service
station sustained considerable damage.
From Mt Barker to Jerramungup (17th) hail to golf-ball size smashed
windows and dented vehicles. At Leonora a hailstorm lasting just five
minutes caused considerable damage to the Tarmoola Gold Mine, 30 kilometres
northwest of Leonora on the 17th. Many windows and car windscreens were
smashed and some temporary buildings moved off their bases by winds estimated
at over 150 km/h. Trees were stripped of foliage. One woman was injured
when a hailstone, described as the size of a cricket ball, smashed through
the rear windscreen of her vehicle. Two mine workers were injured, one
being taken to hospital.
On the 17th heavy rainfall from an afternoon monsoonal squall line produced
flash flooding around Darwin city. At Delissaville, 30 kilometres southwest
of Darwin, 47 mm fell in 30 minutes in this squall line, contributing
to a 24 hour rainfall total of 106 mm.
During the night and early morning hours of the 17th, exceptionally
strong east to southeast gully winds, associated with a surging high pressure
system, caused scattered tree damage and power outages across Adelaide's
eastern and southern suburbs
