Tropical Cyclone guidance: November 2009 to April 2010

Tropical cyclone (TC) activity in the southwest Pacific is expected to be near normal for the 2009–10 season. On average, nine TCs occur in the region each year between November and April. Countries east of the date line, including Niue and Tonga, are at higher risk than normal because of the current weak El Niño. French Polynesia (Society and Austral Islands) and the southern Cook Islands can also be affected by TCs during El Niño, so these islands should also remain vigilant. More details about the 2009–10 TC outlook can be found on NIWA's Tropical cyclone outlook webpage.
