Tropical Cyclone Zane (23P) Expected to Make Landfall Over Cape York Peninsula, Australia

Track of TC 23P

Tropical Cyclone Zane (23P) surged in intensity yesterday as a boost in poleward outflow occurred simultaneously with a boost in gradient level flow due to an anticyclone moving off-shore of Queensland.

The system will remain in its current environment of 29 degree surface waters and 15-20 knots of vertical wind shear (VWS) through landfall over the Cape York Peninsula. Track guidance is in excellent agreement up to landfall. Guidance is also consistent that the system will remain weak once it emerges into the Gulf of Carpentaria.

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.

Fires Throughout Cape York Peninsula During Dry Season, Australia – December 6th, 2012

Australia – December 4th, 2012

Wildfires are burning throughout Cape York Peninsula, the northernmost part of Australia, in Queensland. Smoke plumes from multiple fires are visible billowing in various directions, but mostly towards the west.

Fires are common in this region of Australia at this time of year, since humidity drops and temperatures rise beginning with the arrival of the dry season in March, meaning that by the end of November, grasses and woodland trees have reached a very flammable state. Over the last few days, winds blowing at about 20 kilometers (12 miles) per hour have helped sustain fires that were likely started by lightning and human activity.

Australia – November 26th, 2012

Fires continue to affect the Cape York Peninsula, in Queensland, Australia, as of late November (click here for previous images). Here, two main clusters of fires are visible, one above the image center and one below. The smoke from both clusters is blowing westward.

Australia – November 14th, 2012

Smoke from fires on Cape York Peninsula, Queensland, Australia, blows westward over the Gulf of Carpentaria. In the full image, some other, smaller fires can be seen to the south. The peninsula’s land is mostly flat. Although about half of the area is used for grazing cattle, there are also eucalyptus wooded savannahs and tropical rainforests.
