6]  2019/2020 Cyclone Season thoughts on preparation;-

This section will endeavour to generate some thoughts for you

to consider in your preparation for this coming Cyclone season.

One point will be raised each day from today ;-

Point 1;-   Watch the weather forecasts more closely  especially

to the NW around the Solomon Islands, look for Lows monitor

there paths , their strengths, their speed, some times you only

get  3 days warning!!

Point 2;-  Where are you planning to anchor or moor for the

expected Cyclone? If anchoring how many anchors are you

expecting to deploy ? have you checked to ensure your gear

is still servicable . If on a mooring has your mooring been

recently checked for the Cyclone season?

Point 3; General points for your yacht;-

a] Remove Headsail from furler.

b] Tie your mainsail securely to the boom.

c] Remove all awnings.

d] Remove all loose on deck items

e] Ensure  your lines to mooring have chafe gear fitted, do not

run lines through Thimble but use a Knot < bowlin>

f] Ensure you have fuel and provisions for 7 days .

g] You need an anchor light lower than normal  just above

boom height.  More to be added

Point 4;-Your Dinghy/s;-What are you going to do with your

Dinghy? Tie securely on deck? davits are risky! Do not leave

in water behind yacht; Take ashore and tie down –not under

any trees

Point 5-Communications; Ensure your ships VHF is working,

Plus batteries for your handheld, that your cell phone has spare

recharges and that you have the numbers of all your immediate

moored /anchored area fellow Yachts people/crews; numbers of

the Marina's, and Police Station. Ensure you have spare

torch/flashlight batteries and a second torch /flashlight on hand

if possible.

Point 6;- Unmanned Vessels next to you;- Has the vessel  next to

you been prepared for a Tropical Cyclone? If you consider the

vessel is not prepared request in writing to the Marina OR if

Anchored OR if on a private mooring request to the vessel owner

to advise you what plans he /she has in regards to preparing for

a tropical cyclone. Should you be not satisfied contact MSAF

their office is near the main wharf entrance, follow up your

discussions with MSAF with an email to MSAF. It is advisable to

action this point NOW as it may take you some time to make

contact or indeed get any action !!!

Point 7 During Cyclone;- Every vessel should have a constant

Watch reporting on VHF 16 Cruisers Net Control-Curly [ or Cell

phone 868 0878] any problems they have or concerns re other

Vessels.it is hoped that the MSAF Channel Markers and their lights

will survive a Tropical Cyclone, due to terrible Visibility during a

cyclone there has always been a need for marker lights to assist

Vessels to monitor their Position; Regular Weather Updates will

be provided by Net Control(Curly); I am looking for any Cruiser

who has  Winlink-Sailmail to assist in back-up weather-please

respond to Curly. There is a need to Identify a Rescue boat and

crew who could be on standby( in the past years I (Curly) has

done this but I no longer have the big inflatable-Volunteers??

Point 8 ;-  WILL YOU STAY ON BOARD ???? OR GO ASHORE??

DURING THE CYCLONE;-This is a decision only you can make !

Overall the many years  I have been in Fiji the only time I went

ashore my yacht  was washed onto the beach [moderate damage]

and I firmly believed I could have avoided the grounding if I had

been  on board, since then I have always stayed on board and on

7 occassions I believe being on board did make the difference in

avoiding damage to my vessel during the cyclone.

 

IN CONCLUSION;- It is the small prep tasks that cause you major

problems during a Cyclone.perhaps you should format  your own

Tropical Cyclone preparation list ???? START-NOW  ;-))) Action

what  preparation tasks you can do now , AVOID LAST MINUTE

PANIC AS THE TROPICAL CYCLONE APPROACHS…….

 

7]   2019/2020 Tropical Cyclone general Info;-

10 October 2019

NIWA and MetService analyses indicate 9 to 12 named tropical cyclones (TC) could occur in the Southwest Pacific basin between November 2019 and April 2020. This expectation for tropical cyclone activity is close to normal for the region, but with elevated activity east of the International Date Line especially during the late season between February and April.

Tropical cyclones have a significant impact across the Southwest Pacific, with the season officially starting in November and lasting until the end of April.

Vanuatu and New Caledonia typically experience the greatest TC activity, with an average of about two or three named cyclones passing close to those islands each year. For this season, the expectation for those two islands is normal, while Wallis & Futuna, Tuvalu, Fiji, Samoa, American Samoa, Niue, Tonga and the Southern Cook Islands may experience two or more cyclones.  Four severe cyclones reaching Category 3 or higher might occur anywhere across the region.

On average, at least one ex-tropical cyclone passes within 550km of New Zealand each year. For the coming season, the risk for an ex-tropical cyclone affecting New Zealand is considered near normal. If an ex-tropical cyclone comes close to the country, it is more likely to pass east of the North Island, and landfall of a degrading storm system is possible. Significant rainfall, extreme winds, hazardous marine conditions and coastal damage can occur leading up to and during these events. 

At present, sea surface temperature anomalies across the central Pacific are warm (positive), while the eastern equatorial Pacific Ocean is cool (negative). Atmospheric circulation patterns over French Polynesia and northern Australia indicate ENSO (El Niño-Southern Oscillation)  neutral conditions, but are leaning toward El Niño. Oceanic and atmospheric forecasts for ENSO indicate neutral conditions for the TC season are most likely, with lower probabilities that some type of El Niño may develop by mid-summer.  It is worth noting that if  El Niño develops it may be of the Modoki type (central Pacific-based) during summer.

There is no expectation that there will be any reduction from normal tropical cyclone activity for the coming season. Increased TC activity is expected for several islands east of the International Date Line, including Samoa, American Samoa, Tonga, Niue the southern Cook Islands, and especially near the Austral Islands.

Tropical cyclones are categorised in strength from 1 to 5, with 5 being the most intense. For the coming season, about four storms are anticipated to reach at least Category 3 strength, with mean wind speeds of at least 118 km/h winds.

Past years with conditions similar to present suggest several storms that develop could intensify to at least Category 3 strength. Category 5 strength cyclones, where wind gusts exceed 199 km/h, have occurred in some years with similar conditions leading into the 2019/20 season (known as 'analogue' seasons). Therefore, all communities should remain alert and well-prepared for severe events.

New Zealand should also remain vigilant as the season unfolds. During some analogue seasons used in the preparation of this seasonal outlook, multiple ex-tropical cyclones passed within 550 km of the country. Significant wind, waves and rainfall are possible from ex-tropical cyclone interactions. Their effects can be spread over a large area, particularly if the decaying storm system of tropical origin interacts with separate weather systems embedded in the middle latitudes. 

All communities, regardless of changes in TC risk, should remain vigilant and be aware if the regional climate situation (including ENSO) changes. As with most years, TC activity is expected to increase during the second half of the season from February-April. Early season TC activity is expected to be near normal.

NIWA, MetService, MeteoFrance, BoM, NOAA and Pacific Island National Meteorological Services will all continue to track the progression of ENSO and TC activity, with an update to this guidance in January 2020 if needed.

It does not take a direct hit or a severe cyclone to cause significant damage or life-threatening weather. When dangerous weather is forecast, please heed the advice of your local civil defence or disaster management offices.
