STORMPLANET - Severe Event Reports
December 3rd & 4th
2003
Central & Nth Central Districts, Victoria.
December 3rd |
December 4th
Cloud across VIC, NSW and QLD formed a broad trough causing heavy
rain and widespread thunderstorms. The thunderstorms continued
throughout eastern and northern VIC as a broad trough of low pressure
over eastern Australia tapped into a plentiful supply of moisture from
the northeast. A Severe Thunderstorm Advice was issued for all districts
of VIC, except the Western. The heaviest 24 hour totals in VIC on
Tuesday were 120mm at Wonnangatta River, and 108mm at Bulleen which
caused flash flooding. Melbourne was again the target of many storms as
the near stationary trough combined with the sea breeze to set up a
convergence zone northwest of the city. Northwesterly middle level winds
then pushed the storms across the city. The heaviest rain total to
3:30pm was 17mm at Mt Moornapa, however significantly higher totals will
be recorded to 9am.
I was positioned in an area
bordered by Healesville, Yarra Glen and Coldstream. No severe storms
were observed today but some cells near Healesville produced heavy rain
and some nice photographic opportunities.

Some interesting cloud structures
were observed and some photogenic rain bases photographed. There was
some visible lightning, and a lot of thunder as the cell depicted in the
above radar moved through near Healesville. Rain was very heavy however
no hail was observed.
December
4th
A broad, slow moving trough,
combined with an atmosphere rich in moisture that flowed in from the
tropics, continued to trigger widespread severe thunderstorms across
eastern states. There was very intense rainfall in most storms and large
hail with wind squalls in some. The highest falls were centered around
the NSW Riverina, Central West and VIC Northern Country, North Central
and Central districts. To 9am Thursday, Tottenham (NSW) received 74.6mm
and Mt Baw Baw (VIC) 50mm. To 3pm, Mildura (SW NSW) scored 49.6mm with
23.2mm falling in just 10 minutes and Badgery's Creek in Sydney recorded
a wind gust to 100km/h.
I was chasing in the Central &
Nth Central Districts, between Yarra Glen and Seymour. The images below
start with a couple taken from Nth Croydon looking east, nice pileus cap
on the cell which had delivered heavy rain east of Lilydale, as had an
adjacent cell over Mt Dandenong. The remaining images were captured in
the Yea & Seymour area.
