Heavy rain recorded at Gilmore North 15th February

[Gavin O'Brien]

Hi all, 

As seems the pattern in recent years our rainfalls are coming as heavy events over short time scales. Again, this month we have had a heavy fall with a thunderstorm mid evening. We recoded 14.1mm between 8pm and 8.10 pm with a maximum rainfall rate of 101.0mm/hr. at 8.03pm. Our monthly total is now 61.4mm -quite reasonable but also all of the total has come as two short but intense events with storms. Too much water runs off and is not soaking into the ground.

I am noting that many deciduous trees are going into autumn mode already or just shedding leaves, a sign of moisture stress.

The Pilbara seems to have escaped relatively likely from the Cat 5 Tropical Cyclone crossing today.

Cheers,

Gavin

Hi Gav.

 

Similar thing here. There are so many trees falling over and is quite noticeable. Some massive branches are getting dropped as well.

 

Regards Bussy

On the subject of deluges, I noticed yesterday that the hailstorm that affected Harden-Murrumburah and surrounds last Monday morning has left a scar that's visible even in geostationary satellite imagery (the pale area running ENE above the pink arrow).

Presumably it's the result of the massive volume of hail and water temporarily affecting pasture growth.

That's a great photo. Haven't seen anything like that before (but that's probably because I haven't been looking in the right places).

That's a good catch Andrew. I would never have spotted that.

Another recent instance on a slightly finer scale was written up last year, when a scar produced by a tornado in 2022 was found on the Nullarbor.

The ABC story is at https://www.abc.net.au/news/science/2024-11-27/nullarbor-plain-tornado-recorded-storm-weather-event/104638086, and I have some other imagery (including lightning tracks from the storm responsible) at https://posts.anero.id/@andrewmiskelly/statuses/01JDP4DKFGV6T43KPM9GBKVX2D.
