Tropical Cyclone guidance and activity: November 2009 to April 2010
There were two tropical cyclones (TCs) that occurred in the southwest Pacific during January. “Nisha” was the second TC to form in the region, and developed on 27 January to the northeast of Fiji. The system gradually strengthened into a Category 1 TC, reaching winds of 75km/h. The third TC to form during the season was “Oli”, which developed on 29 January and was upgraded to a tropical depression on 30 January. Eventually in February, Oli would be categorised as the first severe TC (with winds up to 185km/h) to form in the southwest Pacific during the 2009/10 TC season. Updated TC guidance indicates increased risk or the Solomon Islands, and to the east of the Date Line for Tonga, Niue, and the Southern Cook Islands for the remainder of the TC season.
