It is extremely rare for a powerful tropical cyclone to make landfall,
weaken significantly, then later re-intensify back into a powerful storm
again--but Cyclone Ingrid did just that. After crossing Queensland's Cape
York Peninsula on the 10th of March 2005, Cyclone Ingrid appeared to have
all but dissipated. On the 11th of
March a greatly-weakened Ingrid re-emerged over open water in the Gulf
of Carpentaria. In a phenomenal re-birth, Ingrid rapidly re-intensified
going from tropical storm strength back to a Category 4 cyclone with
maximum sustained winds estimated at 120 knots (138 mph) by the Joint
Typhoon Warning Center in the span of just 12 hours. The Tropical Rainfall
Measuring Mission satellite captured this image of a rejuvenated Ingrid
just off of the northeastern tip of Australia's Northern Territory. The
image was taken at 16:05 UTC 11 March 2005 (2:05 am 12 March 2005 Australian
CST). The image shows the horizontal distribution of rain intensity (top down
view) as viewed by the TRMM satellite. Rain rates in the center swath are
from the TRMM Precipitation Radar (PR), while rain rates in the outer swath
are from the TRMM Microwave Imager (TMI). The rain rates are overlaid on
infrared (IR) data from the TRMM Visible Infrared Scanner (VIRS). The center
of Ingrid appears well-defined with a tight, symmetrical eye. Heavy rain
rates (red areas) are embedded in the eyewall, and good banding is evident
in the arcs of moderate rain intensity (green arcs) surrounding the eye.
Ingrid continued to move due west, paralleling the coast and remaining over
over water. This also allowed the storm to strengthen even further, becoming
a Category 5 Super Cyclone on the evening of the 12th (local time). During
the night of the 12th and early morning of the 13th (local time), Ingrid
hammered Croker Island with reports of recorded winds reaching 320 kph (198
mph), devastating the island. Fortunately, there were no reported deaths or
injuries as residents took shelter. Continuing westward, Ingrid next crossed
northern portions of the Cobourg Peninsula followed by Melville and Bathurst
Islands north of Darwin. This next image taken by TRMM at 15:50 UTC on the
13th (1:50 am 14 March Australian CST) shows Ingrid right over the northern
tip of Melville Island. At the time, Ingrid was a Category 3 storm with
maximum sustained winds estimated at 100 knots (115 mph). An eye is not
readily apparent with the storm's circulation having been disrupted by its
passage over the Cobourg Peninsula and Melville Island. However, a large
area of intense rain (red area) still exists near the center with prominant
banding still visible in the surrounding rain field.
After passing over the northern tip of Bathurst Island, Ingrid entered the
Timor Sea and was once more over open water. The storm now took a more
southerly course heading southwest and began to strengthen yet again. On
the 14th of March, remarkably, Ingrid reached Category 4 intensity for the
3rd time with winds estimated at 115 knots (132 mph). The final image was
taken at 05:45 UTC (3:45 pm Australian CST) on the 15th. Although the center
of Ingrid only falls within the TMI swath, a complete eye is clearly visible
once again (green circle) with localized areas of heavy rain (red areas)
embedded in the eyewall. Near the time of this image, Ingrid's sustained
winds were estimated at 130 knots (150 mph). Ingrid finally came ashore
on the northern coastline of Kimberley in Western Australia on the night of
the 15th of March (local time) near Faraway Bay.
