However, the system was named Cyril by the FMS during March 17, after a couple of satellite images, revealed more prominent cloud banding and a larger convective overcast around the systems centre. The system subsequently peaked with 10-minute sustained winds of 45 knots during the next day, before it started to accelerate south-eastwards and rapidly weaken. The system was last noted during March 21, while it was located about Cyril caused significant flooding within Fiji's Northern and Western divisions, with a peak of 5.62 m ft on reported during March 18 within the town of Nadi, while a small storm surge of 0.3 m ft on was observed within Nadi's bay on the same day.Mcgree, Simon 33 Risk Frontiers Yeo, Stephen W Flooding in the Fiji Islands between 1840 - 2009 December 16, 2010 http://www.riskfrontiers.com/RFfrontimages/Floods%20in%20Fiji%201840-2009%20-%20Risk%20Frontiers%20final.pdf December 31, 2012 Devi, Swastika dead https://web.archive.org/web/20140316104935/http://www.riskfrontiers.com/RFfrontimages/Floods%20in%20Fiji%201840-2009%20-%20Risk%20Frontiers%20final.pdf March 16, 2014 http://www.pacificdisaster.net/pdnadmin/data/original/FJI_MET_2001_floods1840_2000.pdf Pacific Disaster.net List of floods occurring in the Fiji Islands between 1840 - 2000 August 15, 2001 Fiji Meteorological Service 13 December 31, 2012 Information Sheet No. 125 dead https://web.archive.org/web/20120422154924/http://www.pacificdisaster.net/pdnadmin/data/original/FJI_MET_2001_floods1840_2000.pdf April 22, 2012 mdy-all Unnamed tropical cyclone SPac Unnamed TC 1984-03-23 1200Z.png Unnamed 2 1984 path.png March 23 March 30 990 40 Another unnamed tropical cyclone existed from March 23 to March 30.
