Downgraded to just a low now and moving Westwards away from the coast .

The obituary will start later today for ex TC Frances .

Any contributions gladly accepted .

TC Frances took awhile to get going but once into the Tmor Sea quickly intensified and went to Cat2 then Cat 3 within a day .

Stayed a TC for 3 days which is not a long time but considering all the factors she had to deal with she did pretty well.

Unfortunately Frances once a couple of hundred kilometers off the North Kimberley coast and heading in a southwesterly encountered some fairly unfavorable shear and dry air which wrapped into its circulation and ultimately cause her demise.

Frances is gone but not forgotten although no real impact on the coast except for some very heavy falls in Tiwi Islands and few other parts of the NT.

Yeh Desieboy was an interesting system that's for sure. After two duds in the same area this one suddenly went "bang" and powered up nicely.
And models were pretty good predicting it as well apart from its intensity that I reckon surprised them a bit.
This mornings sat map shows some good convection in its vicinity again so there may be some good falls about the NW Kimberley coast today.

Yep Jimmy ,models were pretty accurate once they jumped on board with this system .

Frances was pretty amazing how it battled through the Arafura Sea with quite a few different steering mechanisms affecting her and troughs trying to steal away available moisture.

Also Frances was sitting on edge of some pretty strong shear at one stage during her inception and battled through that as well..

All in all think TC Frances was a good system and a good learning curve on how a low may form ,develop ,steer and intensify especially with so many influential factors to deal with.

A bit of convection definitely still there today being drawn in by a bit of a trough from the south.
