May 23 rainfall

 This covers the rainfall even of 23 May 2025.  Although the rain came down the East Coast looking at a BoM map it doesn't look to me like an East Coast Low.  Here is the radar at 1150 hrs on 23 May 

.. and again at 1915hrs.
Over the whole day my Weather Station collected 77.6mm.    Here are some other local sites (neither of the Wunderground sites in Mallacoota of which I am aware are currently online, possibly reflecting the unreliable power supply at present).  I am very surprised at the low fall recorded at Gabo.
My WS shows falls through the day becoming very heavy in the evening.
The low fall at Bombala AWS suggests there will be little water coming down from the headwaters of  the Genoa River, but the worthwhile rain at Nungatta gives warning  of a good flow on the Eastern side of the ranges coming down Nungatta Creek affecting the Genoa Gorge Flood Gauge later on 24th.  At present it is well below Minor Flood level, but rising.
The fall at Nungatta may/probably also indicate rain falling in the headwaters of the mighty Wallagaraugh, to join up with the Genoa at Gipsy Point.  Together these flows  may offer interesting times for Bottom Lake in the near future.

The height peaked at 0745 on 24 May and has been slowly dropping since then.
The evening was blessed with an excellent sunset:

THis was a panoramic shot from my phone.  An idea to experiment with.
As the lightfades.
On the 25th I took a drive up to the (not close to a) flood gauge.  When I arrived it was measuring 1.12m so had dropped 0.27m (pretty close to a foot in old money) from the peak around 0800 hrs the previous day.  All was very calm upstream ...
.. but rather less so downstream.
The curious point was the state of the track from Wangarabell Rd.  Someone seems to have tried pruning some of the vegetation beside the track.  However:
  • they seem to have whacked small trees at random (several species, at various distances from the track); 
  • used very crude implements not an axe nor clippers or a brush cutter);
  • given up after about 300m (ie about halfway to the small shed); and
  • just left the material scattered across the track (thus making it more difficult to walk on).
