Cyclone Debbie formed in the Coral Sea on 22 March 2017, and eventually intensified to a Category 3 storm (ADT | SATCON) as it moved southward toward Australia. Himawari-8 Visible (0.64 µm) and Infrared Window (10.4 µm) images (above) showed the eye of Debbie as it was making landfall in Queensland, near Prosperpine (YBPN).

The Landsat-8 satellite made an overpass of the eye at 2358 UTC (above), as a large convective burst had developed within the northern semicircle of the eyewall (which was also evident in the corresponding Himawari-8 Visible and Infrared Window images viewed using RealEarth).

Debbie was undergoing an eyewall replacement cycle as the storm center approached the coast — this was evident in Microwave (85 GHz) images from GMI at 1425 (above) and SSMIS at 2017 UTC (below) from the CIMSS Tropical Cyclones site.

The MIMIC Total Precipitable Water product (below; also available as an MP4 animation) showed copious tropical moisture associated with Cyclone Debbie, which led to rainfall accumulations as high as 780 mm (30.7 inches) — with rainfall rates up to 200 mm (7.9 inches) per hour — and record flooding along the coast from Brisbane to Lismore.
