A few records (or near-records) for high minimum temperatures that
have popped up recently:

- Melbourne this morning recorded its ninth 20+ minimum this month.
This is a record for a single month (beating 8 in February 1968 and
January 1981). Not bad when it's only the 15th! The record for a summer 
is 21 set in 1980-81 (the 1998-99 summer total is currently somewhere
between 12 and 14, depending on which side of 20 a couple of January
mins which were 20 to the nearest degree fall).

- there have been 5 consecutive 20+ minima in Melbourne. This is the
  longest such run beginning in February. Taking all months, there has
  been one run of 6 (16-21 January 1908) and three others of 5 
  (9-13 March 1934, 28 January-1 February 1974, 14-18 January 1981).

- there have been 5 consecutive minima exceeding 17.5 in Hobart (I
  only have rounded figures at the moment, so 18 rounded to the 
  nearest degree must be at least 17.6). This is a record for any
  month (previously 4, 13-16 February 1995). 

Hobart is on course to break its record for highest mean minimum for
a month (14.8, February 1972) by a substantial margin - it's currently
on 16.5, so an average of even 13 for the rest of the month would be
enough. Melbourne's mean for the month is currently 19.2, marginally
ahead of the 1997 record of 18.8, but probably not by enough to stay
above it unless there is another heatwave.

[snip thread]

I've taken video at Dee Why (Sydney Northern Beaches) on Saturday
evening (13/2/1999) of waves peaking at between 6m and 8m before
engulfing surf board riders. There was, at times, a considerable surf
operating in the pool that at one time washed a child away in the
kiddies pool unawares to his parents. I was lucky enough to see the
next and larger wave coming with enough time to pluck the child from
the water before he got washed over the side of the pool into the
rocks. These were some of the largest waves that I've videoed since a
similar swell produced monsters near Wollongong nearly 2 years ago.

Bom internet radar images are probably "averaged" over a 10min period.
Many storms produce intense precipitation bursts that last
considerably less than this time over a particular area. To get a
truer picture, you'd have to sit in front of the real radar display
watching and recording each sweep. Perhaps someone else might like to
comment on how effective the BoM internet radar product is at
rendering such precipitation burst conditions typical of many storms.

Tomorrow looks like it could be promising in the sydney region and ive
alrady organised to meet Matt Piper at parramatta station at 11am, from
there we will head to rooty hill and watch and wait..David Croan is also
likely to come with us, and will most likely meet us at Rooty Hill at 11.30am.
Anyone else who wishes to come please mail me so we can get an idea of
numbers/cars etc. If you read this to late, just come along anyway :)
(LI's from -2 to -4, TT's 50+,jet of 50kts + and plenty of moisture around
and a trough to top it off)

At the moment there is alot of moisture haze aruond with temps around 30
and small cu starting to develope around the mountains.Hopefully giving a
hint of what will happen tomorrow!

The images are not averages of 10 mins, but a snapshot at the time
indicated. For details about the BoMs radar check the info on their pages:

http://www.bom.gov.au/reguser/by_prod/radar/
http://www.bom.gov.au/reguser/by_prod/radar/radarexp.shtml
this has some sample images as well.

The local scale (256km diameter) radar images seem to give a fairly good
indication of thunderstorm type rainfall bursts, based on radar I have seen
and the rainfall figures recorded. I'm not sure how effective it is in
large scale rainfall like that from the cyclone, but remember if areas of
yellow are consistently showing up then the area affected is likely to be
receiving at least 20mm/hour, probably more, which soon adds up to a lot of
rainfall in 24 hours. And given strong winds, it's probably more like
30-40mm/hour.

regards, Michael

Those ocean pools can be dangerous, a lady was nearly washed out of the
Kiama rock pool on Sunday, there is a chain and thats all that was stopping
her. The problem was she arrived in calm spot between sets and thought that
the pool edge near this chain was a great place to be. The people in the
pool itself were in no danger as the water is quite deep and only the
surface 12-18ins spills overs the edge after a big wave. Naturally there was
a crowd a daredevils standing on the ocean edge of  pool waiting to get
blasted back into the pool everytime a large wave hit.

Today ( Monday ) there is still 6-8ft of swell, with odd bigger sets on
ocean reefs. Sorry about the imperial measurements, but metres are not
flexible enough for surf size description. For example there is a world of
difference between a 1m wave and a 2 m wave, one is small, the other is a
decent surf.

Looking at the sat motion from the area it seems that the equatorial
section of the system was a separate entity, then another system came
WNW of the NE side of PNG and had some cloud overlap during part of
the time.

Some west to east propagating tropical upper tropospheric wave caused
some subsidence and eroded the cloud overlap and the system NE of PNG
dissipated.

I hope everything goes off for tomorrow, the only nagging doubt I have is
that the Li are nearly as good this afternoon, yet there is nothing, the
southerly change should kick it over the line tomorrow though.

As for the BOM Wednesday forecast of showers and storms, sorry, but I am
writing it off ( which of course has just raised the chances immensely ).

I will not be doing a chase as my wife will have the transport sown up for
the evening, so I hope something develops over lake Illawarra.

At 9.25pm EDT it is still 28 degrees. There is some scattered 
mid level cloud.

The main reason for the post is to pass on a sighting of a pretty
lively looking cell that developed from around 5.30pm well to the 
SE of Canberra (around 100 - 150km to the SE). It seemed to have
an overshooting top and was visibly active until around 7.00pm 
when I lost sight of it as the AC/AS from the west moved in and
obscured visibility.  (It shows up well on the animation at
http://wwwghcc.msfc.nasa.gov/GOES/gms5ir.html  )

So Sydneysiders, there is certainly potential in this evening's 
atmosphere for a good day tomorrow. Just hope the middle level
cloud band doesn't get in the way too early.

Some showers developed over the Brindabellas earlier this 
evening but that activity seems to have dissipated as it 
moves east. 

The GMS shows a thickening of the middle level band so we could 
be in for some light rain overnight. 

Its situations like this where I think about subscribing
to the radar. Come to think of it the daily subscription could
just tempt me if it was available (even at the expensive rate
sought by the BOM - although it seems to be a long time in
coming.
