Cyclone Guba (JTWC designation: ''02P'', also known as Severe Tropical Cyclone Guba) was a tropical cyclone that resulted in 149 fatalities and severe damage across southeastern Papua New Guinea. The first named cyclone of the 2007-08 Australian region cyclone season, Guba formed on November 13, 2007 close to the island of New Guinea, and reached tropical cyclone intensity the next day by the Tropical Cyclone Warning Centre (TCWC) in Brisbane, with the TCWC in Port Moresby assigning the name Guba. It meandered in the northern Coral Sea for the next week, strengthening to a Category 3 severe tropical cyclone on November 16. It posed a threat to the Australian Cape York Peninsula, but remained offshore, and finally dissipated on November 20. ==Meteorological history==
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,〔(Gale Warning for North Eastern Area: Tropical Low ). Bureau of Meteorology (November 13, 2007). Retrieved on November 15, 2007.〕 while the Joint Typhoon Warning Center (JTWC) issued a Tropical Cyclone Formation Alert on the storm.〔(Tropical Cyclone Formation Alert ). Joint Typhoon Warning Center (November 13, 2007). Retrieved on November 15, 2007.〕 Later that day, the JTWC issued its first advisory, designating the low as Tropical Cyclone 02P.〔(Tropical Cyclone 02P Warning NR 001 ). Joint Typhoon Warning Center (November 13, 2007). Retrieved on November 15, 2007.〕 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.〔(Gale Warning for North Eastern Area: Tropical Cyclone Guba ). Bureau of Meteorology (November 14, 2007). Retrieved on November 15, 2007.〕 The name ''Guba'' is a boy's name in Papua New Guinea meaning 'a rain squall on the sea'.〔Johnson, Leonie. "(First cyclone named )", ''Townsville Bulletin'', November 14, 2007. Retrieved on November 14, 2007.〕 Guba drifted erratically off the Queensland coast for the next two days, and cyclone warnings were cancelled when TCWC Brisbane expected the cyclone to remain slow-moving. Guba began drifting southwards and intensified on November 16, becoming a Category 3 severe tropical cyclone. Guba was a small, but intense system, forming a well-defined eye. Guba began weakening on November 17 and was downgraded to a Category 2. After downgraded to a Category 1 cyclone on November 18, it started to accelerate to the west towards the Queensland coast. Cyclone watches and warnings were declared again on November 19 as the cyclone was expected to move closer to the coast and intensify. This did not materialise, however, as Guba then turned northwards later that day, avoiding the Australian mainland, then northeast while it continued to weaken. TCWC Brisbane downgraded Guba below tropical cyclone strength, and issued its last advisory early on November 20.
