The JTWC noted that animated infrared imagery showed that the convection over the weak low-level circulation was poorly organized. Radar imagery showed that bands of thunderstorms were fragmented over the northwestern quadrant of the low pressure area.
Surface observations today (March 11) from Mornington Island and Kowanyama showed light winds (less than 10 knots/11.5 mph/18.5 kph) and sea level air pressure values near 1009 millibars. Maximum sustained surface winds were estimated at 15 to 20 knots/17.2 to 23.0 mph/27.7 to 37.0 kph. JTWC noted that the potential for the re-development into a tropical depression or tropical storm is low over the next day.
The Australian Bureau of Meteorology does not have any current warnings in place for Gillian's remnants, but cautioned, "People from Burketown to the QLD/NT (Queensland/Northern Territory) border, including Mornington Island and Sweers Island should consider what action they will need to take if the cyclone threat increases."
The TRMM Satellite's Precipitation Radar data was used to create this 3-D flyby over Tropical Cyclone Gillian on March 10. Some powerful storms within Gillian reached heights above 16 km/~9.9 miles.
