The season ran from February 5, 1985, to May 22, 1986, with tropical cyclones officially monitored by the Fiji Meteorological Service (FMS), Australian Bureau of Meteorology (BoM) and New Zealand's MetService. The United States Joint Typhoon Warning Center (JTWC) and other national meteorological services including Météo-France and NOAA also monitored the basin during the season. During the season there was nine tropical cyclones occurring within the basin, including three that moved into the basin from the Australian region. __TOC__ Seasonal summary During November and December no significant tropical cyclones developed in or moved into the basin in the region, Systems Severe Tropical Cyclone Ima SPac Ima 1986-02-08 0200Z.png Ima 1986 path.png February 5 February 16 940 90 75 Severe Tropical Cyclone Ima existed from February 5 to February 16.

About 24 hours later, the system intensified into a Category 1 cyclone on the Australian intensity scale. Around that same time, the NPMOC followed suit by upgrading the system into a tropical storm. Gradually intensifying, the FMS estimated that June had peaked in intensity with winds of 65 mph km/h on 5 late on February 7. Meanwhile, the JTWC reported that Tropical Cyclone June had also peaked in intensity.Joint Typhoon Warning Center Naval Pacific Meteorology and Oceanography Center Tropical Cyclone 14P Best Track United States Navy, United States Air Force http://www.usno.navy.mil/NOOC/nmfc-ph/RSS/jtwc/best_tracks/1986/1986s-bsh/bsh141986.txt https://web.archive.org/web/20120917021110/http://www.usno.navy.mil/NOOC/nmfc-ph/RSS/jtwc/best_tracks/1986/1986s-bsh/bsh141986.txt dead September 17, 2012 October 27, 2012 By February 9, June had weakened into a tropical depression.

At Honiara International Airport, 340 mm in on of rain was measured over a three-day period. Increased river flow caused by the depositing of saturated material in rivers was the cause for much of the flood damage that occurred. Of all the islands, Malaita was the worst affected by the cyclone.

Season effects This table lists all the storms that developed in the South Pacific basin during the 1985–86 season. It includes their intensity on the Australian Tropical cyclone intensity scale, duration, name, areas affected, deaths, and damages. For most storms the data is taken from TCWC Nadi's and or TCWC Wellington's archives, however data for 03P has been taken from the JTWC/NPMOC archives as opposed to TCWC Nadi's or TCWC Wellington's, and thus the winds are over 1-minute as opposed to 10-minutes. |- | 02 Ima || 1229 February 5 – 16 || bgcolor=#A4|4 Category 4 severe tropical cyclone || bgcolor=#A4|90 kn km/h mph 5 out on on || bgcolor=#A4|940 940 hPa inHg 4 on || Cook Islands || 00 None || 00 None || |- | 01 June || 1226 February 5–10 || bgcolor=#A2|2 Category 2 tropical cyclone || bgcolor=#A2|55 kn km/h mph 5 out on on || bgcolor=#A2|980 980 hPa inHg 4 on || || 00 None || 00 None || |- | 03 Keli || 0109 February 8–14 || bgcolor=#A1|1 Category 1 tropical cyclone || bgcolor=#A1|45 kn km/h mph 5 out on on || bgcolor=#A1|987 987 hPa inHg 4 on || || None || None || |- | 04 Lusi || 0109 March 2–10 || bgcolor=#A1|1 Category 1 tropical cyclone || bgcolor=#A1|150 75 km/h mph on 5 || bgcolor=#A1|990 990 hPa inHg 4 on || Vanuatu || None || None || |- | 05 Alfred || 0116 March 7–11 || bgcolor=#A1|1 Category 1 tropical cyclone || bgcolor=#A1|150 75 km/h mph on 5 || bgcolor=#A1|990 990 hPa inHg 4 on || Vanuatu || None || None || |- | 06 Martin || 0119 April 10–15 || bgcolor=#A3|3 Category 3 severe tropical cyclone || bgcolor=#A3|120 120 km/h mph on 5 || bgcolor=#A3|970 970 hPa inHg 4 on || || None || 00 None || |- | 07 Namu || 0126 May 16–22 || bgcolor=#A3|3 Category 3 severe tropical cyclone || bgcolor=#A3|150 150 km/h mph on 5 || bgcolor=#A3|955 955 hPa inHg 4 on || Solomon Islands || 100000000 $ || 100 63 - 150 || |- 7 systems February 5 – May 22 165 km/h mph on 5 940 hPa inHg 4 on >100000000 $ 103 References 2 External links 1985 y 1980 South Pacific cyclone yes Category:South Pacific cyclone seasons Category:Articles which contain graphical timelines Category:Tropical cyclones in 1985 Category:Tropical cyclones in 1986
