Fires Near Gulf of Carpentaria, Australia

17.7S 137.9E

Australia – April 22nd, 2013

Fires can be seen near the Gulf of Carpentaria, in the border area between Queensland (right) and the Northern Territory (left), in Australia. Red markers show the precise locations of the fires, while the smoke emanating from them can be seen blowing in a more generalized cloud towards the southwest.

Area of Convection Over Gulf of Carpentaria, Australia

Australia – January 26th, 2013

An area of convection hangs over the Gulf of Carpentaria, between the Northern Territory and Queensland, Australia. Warning centers have not reported any concern over the system developing into a tropical storm. Although the convection covers the gulf, its shoreline can be seen thanks to the use of the Chelys Satellite Rapid Response System (SRRS) “borders” feature (best observed in full image).

Track of TC 11P

On 17 January, TCWC Darwin reported that a tropical low had formed near the coast of Northern Australia. The system intensified into a category one tropical cyclone on 21 January (click here for previous images).

Tropical Cyclone Oswald (11P), located approximately 155 nm east-northeast of Mornington Island, Australia, has tracked east- northeastward at 05 knots over the past six hours. The initial position is based on radar imagery with good confidence.  In the full image, the outline of the Cape York Peninsula can be observed in grey, through the convection, due to the use of the Chelys Satellite Rapid Response System (SRRS) “borders” feature.

Over the past twelve hours, animated infrared (IR) satellite imagery has depicted slight weakening of deep convection near the center. However, IR imagery continues to show an extensive area of deep convection displaced to the north. The initial intensity is assessed at 35 knots

Radar imagery depicts weak convective banding associated with the broad low-level circulation center (LLCC). Recent observations from Kowanyama, approximately 20 nm southwest of the center, indicate sustained surface winds of only 15 to 20 knots with gusts as high as 30 knots.

TC 11P is forecast to track east-northeastward through TAU 12 and is expected to dissipate by TAU 12. The remnants of the system should turn southward to southwestward in response to a building high to the south and are not forecast to track over the Coral Sea. Dynamic guidance is in good agreement on turning the system southward over land but differs on the timing and degree of the turn. Due to the broad nature of the LLCC and the spread in model solutions, there is low confidence in the JTWC forecast track.

Area of Convection Over Gulf of Carpentaria Has Medium Chance of Becoming Cyclone

Track of Area of Convection

An area of convection is located near 16.6S 136.9E, approximately 425 nm southeast of Darwin, Australia.

Animated enhanced infrared satellite imagery shows a steady increase in deep convection over the northern half of a poorly defined low level circulation center (LLCC). The LLCC continues to track eastward towards the Gulf of Carpentaria, but currently remains over land. In the full image, the outline of the gulf can be observed in grey, through the convection, due to the use of the Chelys Satellite Rapid Response System (SRRS) “borders” feature.

Radar imagery from Mornington Island, Australia supports the LLCC approaching the coast. Upper level analysis indicates the LLCC is located poleward of a subtropical ridge axis and in a region of weak upper level convergence, which is hampering outflow. Observations in the vicinity of the LLCC indicate a central pressure of approximately 998 mb.

Maximum sustained surface winds are estimated at 15 to 20 knots. Minimum sea level pressure is estimated to be near 998 mb. Based on the persistent deep convection and the LLCC approaching the Gulf of Carpentaria, the potential for the development of a significant tropical cyclone within the next 24 hours is upgraded to medium.

Fires in Queensland, Australia and Area of Convection Over Gulf of Carpentaria – December 12th, 2012

Australia – December 12th, 2012

Fires in Queensland, Australia, just south of the base of the Cape York Peninsula and southeast of the Gulf of Carpentaria, release plumes of smoke that blow in a slightly curved shape towards the south-southwest.

Also visible here is the use of the Chelys Satellite Rapid Response System (SRRS) “borders” feature, which allows users to download images with countries’ outlines superimposed over cloudcover. Although an area of convection hangs over the southeastern shores of the Gulf of Carpentaria, the Queensland shoreline can be seen thanks to this feature.
