Himawari-8 Visible (0.64 µm) and Infrared Window (10.4 µm) images
(above) showed Cyclone Kelvin as it made landfall in Western Australia as a
Category 1 storm on 18 February 2018. Kelvin continued to intensify shortly after making landfall, with estimated winds of
80 gusting to 100 knots — and a distinct eye feature could be seen in the Visible and Infrared imagery (as well as
Broome radar data).
A longer animation of Himawari-8 Infrared Window (10.4 µm) images (below) revealed a very large convective burst as Kelvin meandered near the coast early on 17 February — periodic cloud-top infrared brightness temperatures of -90 ºC or colder were seen. After making landfall, the eye structure eventually deteriorated by 18 UTC on 18 February.

The
MIMIC-TC product
(below) showed the development of Kelvin’s compact eye during the 17 February – 18 February period; the eye was well-defined around the time of landfall (
2147 UTC image on 17 February), and persisted for at least 18 hours (
1556 UTC image on 18 February) until rapidly dissipating by
21 UTC.

Deep Layer Wind Shear values remained very low — generally 5 knots or less — prior to, during and after the landfall of Kelvin, which also contributed to the slow rate of weakening. In addition, an upward moisture flux from the warm/wet sandy soil of that region helped Kelvin to intensify after landfall; land surface friction was also small, since that portion of Western Australia is rather flat.

The eye of Cyclone Kelvin could also be seen in Terra MODIS and Suomi NPP VIIRS True-color Red-Green-Blue (RGB) images, viewed using
RealEarth (below). The actual times of the Terra and Suomi NPP satellite overpasses were 0154 UTC and 0452 UTC on 18 February, respectively.
