Sounds like she all done.
From Bom Warning centre 4pm

REMARKS:
Ex-Tropical Cyclone Hilda is weakening over land south of Bidyadanga [between
Broome and Port Hedland]. The small tight circulation is just visible on Broome
radar.

Winds are estimated to have eased below gale force intensity although there is
some uncertainty given there remains an area of deep convection in the vicinity
south of the circulation.
Supporting the weakening are the conservative application of the standard decay
rate now that the centre has now been overland for 15 hours and the range of
surface wind model guidance showing the easing of surface winds. However strong
winds remain aloft so thunderstorms are likely to cause wind gusts to 100 km/h
and a severe weather warning is current for this as well as heavy rain near the
track.

The system will continue to move on a general southerly track over land for the
rest of today and tomorrow. It is likely that strong gusty winds will persist
especially in the southeast quadrant for the next 24-36 hours.

Yes Sepo never thought they would change it though...
Must of been reviewed and decision made to change going on wind speeds.

There's always a post-season review which sometimes leads to systems being downgraded or upgraded (there was one a few years ago which was upgraded post-season from a tropical low to a category 2). Less common to see it while an event is still ongoing, but the measured wind gusts are pretty solid evidence.

Yeah I knew they did that Blair but as you say unusual and I had never seen it done so quickly while the event was still underway... Also makes interesting considerations for recording for Broome town site as Des has been saying lately that Broome AP may have 3mm but Cable beach area or even old Broome area would have had at least 10mm from passing storms. For a TC where wind gusts on Peninsula or Cable Beach, (south), area can be greater then may need to look at upgrading measurement gear at Port or somewhere in southern area of town...

Tessie was a rarity Flowin. It stalled just north of Ingham for almost a full day brining torrential rain to Townsville and surrounding areas. 725mm in 27 hours. Wind wasn't all that great of a problem but it was the 2nd (TC Vaughn was a bust) or 3rd major rain event of the season and the ground was already saturated so flooding was the major cause of damage. I'm hoping that something similar happens this season as we are desperately in need of water or at least a cat 1 or 2 wanders close enough for us to get some decent rainfall.
To put a Cat 1 cyclone into perspective. I went through TC Mitchel protected only by the very best quality Australian Army Hutchie. Yes it was windy and wet. No it wasn't all that scary.

I like Mike Brunker's quote about cyclones. "I wouldn't bother getting out of bed for a Cat 1 cyclone" and basically neither would I.
