Some outlets saying will hit Perth at 5:30. Considering the radar updates every 10 mins, I don't like the chances of it reaching metro for another hour at least.

I want you to go to that window and shout at the wind.

Rotto still gusting over 90kmh
Landing at Perth AP starting to get tricky. They are still doing it on first go.

It's not a well defined front. Looking at satellite images, it's more the tail we have sweeping through with undefined cold unstable air being the dominant feature.

Talk of tornado risk and 125kmph winds.

Not liking the fact I have to drive tonight. Even a short distance.

Tornado risk? :/
Who is talking that up Storm Wolf?

Got the water vapour animation and it's looking like the sting is out if this now.
The Sth coast would be likely to see the nasty stuff.

I think this peaked on the Capes.

Watching a qantas flight have a second go. Wind sheer issues at 150ft aborted landing.

Yeah, just to clarify that, there's definitely no chance of tornadoes with this front. Particularly in the metro area.

Here's tonight's sounding and I'll explain:

Image

1) Despite being very strong, shear is pretty much uni-directional throughout the entire atmosphere. For tornadic activity to be remotely possible, there has to be some rapid shear direction shift with height.

2) The atmosphere is actually quite stable. Slight instability occurs from the surface to roughly 10,000ft but above that the upper air is relatively warm. The worst we're looking at is showers and gusty winds.

Just read this article from The Conversation this morning regarding last month’s storm and the ship/bridge incident in Freo harbour. Meteotsunami… - http://theconversation.com/explainer-ho ... 20tsunamis

Interesting... very interesting.
Image

Basically it's similar to a storm surge, except a storm surge is a temporary elevation of sea level from a sudden drop in surface atmospheric pressure, that is then propelled by the sustained surface wind.. a meteo-tsunami forms from the same trigger - except that the storm front has to possess a velocity in unison with the wave formed to produce enough resonance to sustain and amplify the meteo-tsunami. Also a reasonably wide shallow bay is needed because a specific depth of water is needed to allow the necessary propagation of a wave and to enable sufficient energy transfer from the atmosphere to the ocean.
So a storm surge can occur pretty much anywhere around coastal parts of the world, but only specific locations with the right conditions will produce that meteotsunami phenomena.

One guess who talked up 'tornado risk'. Later found no evidence of that on BOM.

The media, obviously. It was on one of the major news networks on the weather and on the news.

Yeah my friends I was going to meet up with freaked out and we had to cancel because they thought it was gonna be armageddon. I only watched Schultzy on Ch10 and got no impression that it was going to be much at all, just 'a bit blowy' I think he said (ahh, faithful reliable Michael Schultz!). Stupid (other) media...

A bit foggy around parts of the SW this morning.
Donnybrook a little misty.

A few places saw light recordings of precip. :P

Between 0.1mm and 2.0mm covers off on most of what was recorded in the Lower West Coast, SW coast, Sth Coast and SE coastal areas.
