Tropical Cyclone Sunday, January 22, 2017
 Tropical Cyclone

 

The hot or wet season in Vanuatu, which is from November to April, is also known as the cyclone season. The geographical location of the archipelago in the southwest Pacific is on a route occasionally traversed by cyclones, which by definition are associated with winds of at least 34 knots (62 km/hr) or over. 
The area of Vanuatu (land and sea) receives about 2-3 cyclones in a cyclone season, and the greatest frequency is in January and February. On average, Vanuatu and its marginal seas is a common route to some 20 to 30 cyclones per decade, with 3 to 5 causing severe damage.
 
Cyclones are very erratic in their movement therefore often hard to predict, but they generally maintain their southerly movement until about 21 °S to 25 °S when they do a parabolic curve mostly to the east, and dissipate. The archipelago of Vanuatu being small islands grouped together in a north to south distribution are effected by almost every cyclone passing through.
 
Tropical cyclones affecting any islands of Vanuatu can result in heavy rainfall, flooding of low lying areas, coastal flooding, storm surge, land slide, very rough seas and strong to damaging winds inland. These events can cause a great deal of damage to property and live.
 
In the event that a tropical cyclone is expected to affect Vanuatu, the Vanuatu Meteorological Service will give out information regarding the system to all Radio Outlets in Vanuatu as well as the internet (www.meteo.gov.vu). A track map will be also provided on VMS's website.
 
The Vanuatu Meteorological Service encourages all individuals living in Vanuatu, particularly those in rural areas and those who do not have access to internet to always listen to all Radio Vanuatu for information on tropical cyclones. TC Warnings are also disseminated to Radio New Zealand and Radio Australia for broadcasting. The Frequency are as follows:

As Vanuatu is frequently visited by tropical cyclones every cyclone season, the Vanuatu Meteorological Service has in place a very effective Warning System to enure life and property of individuals in Vanuatu is well protected. VMS gives information on a tropical depression or tropical cyclone in three phases, namely Information, Advisory and Warning. VMS also provide the "Vanuatu Tropical Cyclone Tracking Map" position, in both numbers and letters. This is a very effective and simple tool for locals, particularly those in rural areas as it helps to locate the centre of the system.
 
 

Cyclone Names – South West Pacific Ocean

RSMC Nadi is solely responsible to name Tropical Cyclones that occur within Vanuatu’s Area. List A, B, C and D are used in sequence. List E is a standby list; when a cyclones name is retired from lists A, B, C and D, the name from List E is used to replace the retired name.
