Overnight, a tiny tropical cyclone rapidly spun up a few hundred miles off the coast of Queensland. Named Edna, it had winds of 35kts this morning, but winds have since weakened to 30kts, prompting BOM to declare Edna an remnant low. Convection was persistant over the small LLC this morning, but shear has risen which has caused the convection to flare and wane, which has caused the LLC to weaken. Ex-Edna is currently drifting west but is expected to swing north then northeast around the west side of a trough over the Coral Sea. This trough is expected to keep shear at moderate to high levels across the system, so BOM do not expect Edna to become a TC again, though they aren't ruling it out. JTWC have not recognised this system as having reached TC intensity, instead just giving the system's chances of development a MEDIUM risk.
An unusual track to say the least. And a blink and you'll miss it kind of cyclone, unless it comes back:
