The 2007-08 Australian region cyclone season is an event in the ongoing cycle of tropical cyclone formation. It officially started on November 1, 2007, and will end on April 30, 2008. However, the formation of a tropical cyclone on July 27, 2007 marked an earlier beginning to the season. The regional tropical cyclone operational plan also defines a tropical cyclone year separately from a tropical cyclone season; the "tropical cyclone year" began on July 1, 2007 and will end on June 30, 2008.
Tropical cyclones in this area are monitored by five Tropical Cyclone Warning Centres (TCWCs): the Australian Bureau of Meteorology in Perth, Darwin, and Brisbane; TCWC Jakarta in Indonesia; and TCWC Port Moresby in Papua New Guinea.

An area of low pressure on the edge of the area of responsibility with Perth formed into tropical disturbance on July 29. Although no advisory was issued it was monitored and designated a number by Meteo-France. The Joint Typhoon Warning Center had issued a Tropical Cyclone Formation Alert on the developing system a day earlier, and began warnings on Tropical Cyclone 01S later on July 29 with the storm estimated to be centred within Perth's region. The cyclone began to dissipate early on July 30, with the JTWC discontinuing advisories later that day and the Bureau of Meteorology issuing its last warning the next day.
The Bureau of Meteorology upgraded the disturbance to a tropical cyclone in its post-storm analysis, with maximum 10-min sustained winds of 75 km/h (45 mph) based on QuikSCAT observations. The cyclone's intensity was estimated to have reached cyclone intensity from July 29 to July 30. The cyclone is the second on record to exist in the Western Australian region in July, the other being Cyclone Lindsay in 1996.
Tropical Cyclone Guba

| Peak intensity | Winds not specified; |
Template:HurricaneActive The Tropical Cyclone Warning Centre (TCWC) in Brisbane began issuing warnings on a developing tropical low located near the southern Papua New Guinea mainland on November 13, 2007, while the Joint Typhoon Warning Centre (JTWC) issued a Tropical Cyclone Formation Alert on the storm. Later that day, the JTWC issued its first advisory, designating the low as Tropical Cyclone 02P. TCWC Brisbane initiated tropical cyclone advices on the tropical low early on November 14, with a cyclone watch declared for the northern coastal and island communities in the Cape York Peninsula. Shortly after, TCWC Brisbane upgraded the system to Tropical Cyclone Guba, a name assigned by the TCWC in Port Moresby. The name Guba is a boy's name in Papua New Guinea meaning 'a rain squall on the sea'. Guba drifted erratically off the Queensland coast for the next two days, and cyclone warnings for the coast and island communities were cancelled when TCWC Brisbane expected the cyclone to remain slow-moving.
Flooding in Papua New Guinea led to three deaths and about 2,000 people were evacuated as a result.
Guba was the first tropical cyclone to be assigned a name from Port Moresby's name lists since Tropical Cyclone Epi in 2003. It is the first cyclone to occur in the Queensland region in the month of November since 1977.
Current storm information
As of 5 p.m. AEST (0000 UTC) November 16, the BOM reports Tropical Cyclone Guba to be located near 11.4°S 146.7°E, about 390 km (250 mi) east-northeast of Lockhart River, Queensland and 480 km (315 mi) north-northeast of Cooktown, Queensland. The system has maximum 10-minute sustained winds of 65 kt (120 km/h, 75 mph), gusting to 90 kt (170 km/h, 105 mph). It has a minimum central pressure of 970 hPa (mbar), and is drifting south.
As of 0000 UTC November 16, the JTWC reports Tropical Cyclone 02P (Guba) to be located at 11.0°N 146.5°E. The system has maximum 1-minute sustained winds of 50 kt (95 km/h, 60 mph). It has a maximum associated wave height of 16 ft (4.9 m).

Tropical Cyclone Lee-Ariel

| Peak intensity | Winds not specified; |
On November 13, the Tropical Cyclone Warning Centre (TCWC) in Perth began issuing warnings on a developing tropical low which was located within the area of responsibilty of TCWC Jakarta, and was also on the edge off Metro France's area of responsibility. On November 14, TCWC Perth upgraded the Tropical Low to Tropical Cyclone Lee, while the cyclone was still in TCWC Jakarta's area of responsibility. Later that day the Joint Typhoon Warning Centre (JTWC) issued a Tropical Cyclone Formation Alert on Tropical Cyclone Lee, and then designated the storm as Tropical Cyclone 03S shortly after. The TCWC in Perth upgraded Lee to a Category 2 on November 15. Later that day, TCWC Perth issued its final advisory on Lee, due to it moving into Metro France's area of responsibility. As a consequence, it was renamed Ariel by the Sub-Regional Tropical Cyclone Advisory Centre in Mauritius.
Current storm information
Tropical Cyclone Lee is now within the Area of Responsibility of RSMC La Reunion Please see the 2007-08 South-West Indian Ocean cyclone season for current storm infomation
