1008UTC 24 MAY 2014

There are no active tropical cyclones or suspect areas of convection across the South China Sea.

The latest satellite imagery indicates widely scattered showers and thunderstorms to your east. this area could drift westward over the next 6-8hrs, but should also weaken and gradually dissipate through the night/overnight.

Any thunderstorm activity in the area will be responsible for locally gusty winds in the area.

Along your intended route to Singapore expect:

Sat/24 110UTC - Sun/25 0000UTC

Wind: S-SSE to SE 05-15kts, chance more variable at times through late in the period. Locally gusty winds above 20kts possible in/near any thundershower activity.
Sea: 0.5-1.0mtrs. Locally higher in/near heavier showers/thundershower activity.
Swell: S-SSE 1.0mtrs and less.

Sun/25 00000UTC - Sun/25 1200UTC (through arrival Singapore)

Wind: S-SE to variable 05-15kts. Locally gusty winds above 20kts possible in/near any thundershower activity.
Sea: 0.5-1.0mtrs. Locally higher in/near heavier showers/thundershower activity.
Swell: SSE- confused 1.0mtr and less.

This will be our last scheduled forecast, unless otherwise advised. It has been a pleasure providing our services and being part of the delivery of Nordhavn 86/KOONOONA. If I can be of further assistance for any future travel plans, please let me know. B/Rgds, Bob/OMNI

Thanks for your departure report. I see by the live tracking info on the Nordhavn web site you have made your first stop

There are no active tropical cyclones or suspect areas of convection across the South China Sea. Conditions are not favorable for development during the coming days.

The latest satellite imagery indicates widely scattered to isolated showers/thunderstorms across Indonesia as well as around Singapore. However, currently, the strongest activity is over more inland areas. The activity has eased off during the night time hours and this trend should continue through arrival Singapore.

Expect isolated to widely scattered showers/thunderstorms to develop over offshore waters as well as inland. The offshore waters should see the convection weaken/dissipate during the night/overnight hours. Thunderstorm activity in the area will be responsible for locally gusty winds in the area.

Along your intended route to Singapore expect:

Thu/22 18000UTC - Fri/22 0000UTC

Wind: Ranging SSW-SSE 05-15kt. Locally gusty winds above 20kts possible in/near any thundershower activity.
Sea: 0.5-1.0mtrs. Locally higher in/near heavier showers/thundershower activity.
Swell: Confused to southerly 1.0mtrs and less.

Fri/23 00000UTC - Sat/24 0000UTC

Wind: Tending to range more S-SSE 05-15kts. Locally gusty winds above 20kts possible in/near any thundershower activity.
Sea: 0.5-1.0mtrs. Locally higher in/near heavier showers/thundershower activity.
Swell: S-SSE 1.0mtrs and less.

Sat/24 000UTC - Sun/25 0000UTC

Wind: S-SSE to SE 05-15kts, chance more variable at times through late in the period. Locally gusty winds above 20kts possible in/near any thundershower activity.
Sea: 0.5-1.0mtrs. Locally higher in/near heavier showers/thundershower activity.
Swell: S-SSE 1.0mtrs and less.

Sun/25 00000UTC - Sun/25 1200UTC (through arrival Singapore)

Wind: S-SE to variable 05-15kts. Locally gusty winds above 20kts possible in/near any thundershower activity.
Sea: 0.5-1.0mtrs. Locally higher in/near heavier showers/thundershower activity.
Swell: SSE- confused 1.0mtr and less.

We will continue to watch the pattern to Singapore and update daily through arrival. Please keep us closely advised of your position/weather/speed while enroute. B/Rgds, Bob/OMNI

Well, I hate to sound like a broken record, but conditions have improved now that you are south of 10N/lat and this pattern will continue through arrival.

Satellite imagery has indicated clusters of showers/thunderstorms south and east of the coast of Vietnam extending seaward about 300nm. The areas of convection were on the moderate side, but since this activity is not related to a tropical cyclone threat, this activity should gradually weaken and dissipate through the overnight. Observations around the areas of convection noted some locally gusty winds to 20-25kts. Otherwise sustained winds should remain in the 10-15kts with winds as low as 05-10kts at times.

There are no active tropical cyclones or suspect areas of convection across the tropical western Pacific or South China Sea.

Along your intended route to Kuala Terengganu (K.T.) expect:

Fri/16 13000UTC - Sat/17 0000UTC

Wind: SSW-WSW 10-15kts. Locally gusty winds are possible in/near heavier showers and isolated thundershowers.
Sea: 1.0-1.5mtrs. Chance seas ease to 0.5-1.0mtrs by late in the period.
Swell: SW-S 1.0-1.5mts, may mix with WSW to WNW or be just confused, 0.5-1.0mtrs by late in the period.

Sat/17 00000UTC - Sun/18 0000UTC (to arrival)

Wind: WSW-SSW, perhaps some SSE prior to arrival 08-15kts.
Sea: 0.5-1.0mtrs.
Swell: Southerly, maybe confused just prior to arrival, 0.5-1.0mtrs.

We will continue to watch this pattern closely and update daily through arrival. Please continue to advise your daily position/speed/weather reports while enroute. B/Rgds, Bob/OMNI

Observations from the area seem to indicate conditions are starting to improve. Your location as close to the coast of Vietnam is helping ever so slightly to produce a slightly better wind/sea. However, you have passed 15N so conditions are expected to improve to 12N/lat where the trend for improving conditions will prevail through arrival.

Satellite imagery does indicate some showers/thunderstorms off the southern coast of Vietnam. This activity has increased in intensity, but is not considered suspect. Chances are the area is a flare-up of activity that should fall apart during the night/overnight hours.

There are no active tropical cyclones or suspect areas of convection across the tropical western Pacific or South China Sea.

Along your intended route to Kuala Terengganu (K.T.) expect:

Thur/15 1200UTC - Fri/16 0000UTC

Wind: SSE to SSW and subside from 15-25kts to 15-20kts.
Sea: SSW-SW 1.5-2.5mtr, should ease to 1.5-2.0mtrs by late in the period.
Swells: SSW-ly 1.0-2.0mtrs, upto 3.0mtrs still expected at least through 15/1800UTC before tending to subside.

Fri/16 00000UTC - Sat/17 0000UTC

Wind: Easing SSW-WSW 15-20kts to 10-15kts.
Sea: 1.5-2.0mtrs, gradually subside to 1.0-1.5mtrs through the period. Chance down to 0.5-1.0mtrs by late in the period.
Swell: SW-S 1.0-1.5mts, may mix with some WSW to WNW 0.5-1.0mtrs by late in the period.

Sat/17 00000UTC - Sun/18 0000UTC (to arrival)

Wind: WSW-SSW, perhaps some SSE prior to arrival 08-15kts.
Sea: 0.5-1.0mtrs.

Thanks for your latest report.

Observations are showing a slight decrease in the winds very close to the coast of Vietnam. However, it appears to be a very fine line as to where easier winds of 12-20kts are noted, versus where the 20-25kt, gusty redevelop. The direction of the winds continues to remain southerly so there you will continue to have head conditions the next few days.

The only thing you will have going for you is that once you are south of 15N the conditions will start to improve, but should remain 15-20kt at least until 12N/lat. Once conditions ease, the pattern will continue to remain favorable through arrival.

There continue to be no active tropical cyclones or suspect areas of convection across the tropical western Pacific or South China Sea.

Along your intended route to Kuala Terengganu (K.T.) expect:

Wed/14 1800UTC to Thu/15 0000UTC

Wind: SSW-SSE 15-25kt, gusty.
Sea: 1.5-2.5mtrs, 4-6sec.
Swell: SSW-ly 1.0-2.0mtrs. Combined sea/swells of 3.0mtrs expected, 8-9sec.

Thur/15 0000UTC - Fri/16 0000UTC

Wind: Should start seeing some improving conditions by late in the period. SSW-SSE from 15-25kts to 15-20kts.
Sea: SSW-SW 1.5-2.5mtr, should ease to 1.5-2.0mtrs by late in the period.
Swells: SSW-ly 1.0-2.0mtrs, upto 3.0mtrs still expected at least through 15/1800UTC before tending to subside.

Fri/16 00000UTC - Sat/17 0000UTC

Wind: Easing SSW-WSW 15-20kts to 10-15kts.
Sea: 1.5-2.0mtrs, gradually subside to 1.0-1.5mtrs through the period. Chance down to 0.5-1.0mtrs by late in the period.
Swell: Southerly 1.0-1.5mts, may mix with some WSW to WNW 0.5-1.0mtrs by late in the period.

Sat/17 00000UTC - Sun/18 0000UTC (to arrival)

Wind: WSW-SSW, perhaps some SSE prior to arrival 08-15kts.
Sea: 0.5-1.0mtrs.
Swell: Southerly, maybe confused just prior to arrival, 0.5-1.0mtrs.

Thanks for your earlier report.

The latest available observations indicate the unavoidable increased winds you are will need to be dealt with over the next 24-48hrs. However, thereafter conditions begin to improve and once they improve conditions will remain on the lighter side for the duration of the voyage. There are still no active tropical cyclones or suspect areas of convection across the tropical western Pacific or South China Sea.

Conditions are expected to begin easing after crossing south of 15N/lat, but you will still have force/4-5 conditions until you near 12N/lat. The more SSW-SW to occ WSW-W winds should remain at 08-15kts, but as low as 08kt and less during the last 36hrs of the voyage is very possible.

Between Hong Kong to Kuala Terengganu (K.T.) Malaysia Basis along your intended route, expect:

Tue/13 1800UTC to Wed/14 0000UTC

Wind: SSW-SSE 15-25kt gusty,
Sea: 1.5-2.5mtrrs, 5-7sec.

Wed/14 0000UTC to Thu/15 0000UTC

Wind: SSW-SSE 15-25kt, gusty. Winds could begin to ease/veer SSW-WSW 15-20kts late in the period.
Sea: 1.5-2.5mtrs, 4-6sec. Should subside to 1.5-2.0mtrs by 15/0000UTC.
Swell: SSW-ly 1.0-2.0mtrs. Combined sea/swells of 2.5-3.0mtrs still possible, 8-9sec.

Thur/15 0000UTC - Fri/16 0000UTC

Wind: Continuing to ease SW-WSW to WNW: from 15-20kts to as low as 10-15kts through the period.
Sea: SSW-SW 1.5-2.0mtrs to start, subside to 1.0-1.5mtrs to 0.5-1.0mtrs through the period.
Swell: Southerly 0-5.1.0mtrs.

Fri/16 00000UTC - Sat/17 1200UTC (to arrival)

Thanks for your departure and position report.

The latest available observations indicate the winds are a bit easier to your S-SW with winds closer to 10-15kts and sea/swell heights 0.5-1.5mtrs. However these lighter conditions are not expected to continue as they should gradually increase the further south/west you travel.

There continues to be no active tropical cyclones or suspect activity across the tropical western Pacific Ocean or South China Sea. The latest satellite imagery indicates the cluster of moderate to even isolated heavy showers/rain and embedded thundershowers to your south has weakened over the last few hours. A weather front to the north continues to remain well north. However the developing of a low center/trough NW of Hainan island and associated trough extending SE-SSE to off/along the coast of Vietnam will help develop and maintain the stronger southerly wind/sea flow over the next few days.

Conditions are expected to begin easing as you near/cross 12N/lat. In fact, once the conditions ease, the winds will likely subside to 15kts and less with sea/swells 1.0mtrs and less for the remainder of the voyage.

Between Hong Kong to Kuala Terengganu (K.T.) Malaysia Basis along your intended route, expect:

Mon/12 1800UTC to Tue 13 0000UTC

Wind: Increase SSW-SSE 10-15kt to as much as 15-20kt.
Sea: increase from/about 1.0mtrs to 1.5-2.0mtrs, 4-6sec. as the winds increase.
Swell: SSW-S 1.0-2.0mtrs. 8-10sec.

Tue/13 0000UTC to Wed/14 0000UTC

Wind: SSW-SSE 15-25kt gusty,
Sea: 1.5-2.5mtrrs, 5-7sec.
Swell: SW-S 1.5-2.5mtrs. Combined sea/swells upto 3.0mtrs still possible, 8-9sec.

Wed/14 0000UTC to Thu/15 0000UTC

Wind: SSW-SSE 15-25kt, gusty. Winds could begin to ease/veer SSW-WSW 15-20kts late in the period.
Sea: 1.5-2.5mtrs, 4-6sec. Should subside to 1.5-2.0mtrs by 15/0000UTC.
Swell: SSW-ly 1.0-2.0mtrs. Combined sea/swells of 2.5-3.0mtrs still possible, 8-9sec.

Thur/15 0000UTC - Fri/16 0000UTC

Available observations continue to indicate a SSW-SE winds pattern southward the east coast of Vietnam 10-20kts. with sea/heights generally 1.0-2.0mtrs.

There continues to be no active tropical cyclones or suspect activity across the tropical western Pacific Ocean or South China Sea.

A cold front across SE China should stall over the next 12-24hrs while the associated low center moves north/east. The front should lay WSW very close to Hong Kong during Mon/12-Tue/13, while a wave of low pressure forms along the front west of Hainan Island. The combination of the stalled front and low center will enhance the SSW-SSE wind/sea flow persist in the force 4-6 range from SE China to/off the east coast of Vietnam the next few days.

Conditions are expected to begin easing as you near/cross 12N/lat even thought the SSW-SW direction should continue. a bit longer. Once you begin to move more WSW-ly off the coast of Vietnam and across into the the Gulf of Thailand area, light WSW-WNW winds and low sea/swells should develop and prevail through arrival.

Between Hong Kong to Kuala Terengganu (K.T.) Malaysia Basis an ETD Mon/12 along your intended route, expect:

Sun/11 1800UTC to Mon/12 0000UTC

Wind: SSW-SSE 10-20kt, gusty in/around Hong Kong and offshore.

As of today we will resume our daily forecasts for the trip from Hong Kong to Kuala Tenengganu (K.T.) based on an ETD of Mon/12th.

Available observations indicate SSW-SE winds prevail southward from southward toward the east coast of Vietnam 10-20kts. with sea/heights generally 1.0-2.0mtrs. However, reports of as much as 3.5mtrs have been reported (although not verified) east of your intended route.

There are no active tropical cyclones or suspect activity across the tropical western Pacific Ocean or South China Sea. This pattern should continue for the next several days.

A low center across eastern China will move north/east through Sun/11th, while its trailing cold front tends to work its way toward SE China. The southern half of the front should stall across SE China after Sun/1200UTC and then should weaken through Mon/1200UTC-Tue/0000UTC. This will help improve visibility as the risk of heavier/steady rain/showers will ease a bit at departure.

However the trend for the coming days is for the pressure/wind gradient to be strongest along your intended route. Unavoidable forces 4-6 will prevail the first 3-4 days of the voyage. Gradually easing conditions are expected after Ho Chi Minh city that should continue to arrival. Showers/thunderstorms should also be more widely scattered to isolated the further south you go.

Between Hong Kong to Kuala Terengganu (K.T.) Malaysia Basis an ETD Mon/12 along your intended route, expect:

Sun/11 1200UTC to Mon/12 0000UTC

Wind: SSW-S 15-20kt, gusty in/around Hong Kong and offshore.
Sea: 1.0-1.5mtrs, 4-6sec to start, but could build to 2.0mtrs during the strongest once late (if at sea by 12/0000UTC.
Swell: SW-S 1.0-2.0mtrs, Combined sea/swells upto 2.5mtrs possible further offshore, 8-10sec.

Mon/12 0000UTC to Tue 13 0000UTC

Wind: SSW-SSE 15-20kt, upto 25kts very possible at times, once underway and away front the coast.
Sea: 1.5-2.0mtrs, 4-6sec. Seas could also reach upto 2.5mtrs more exposed waters with shorter period (choppy seas)
Swell: SSW-S 1.5-2.0mtrs. Upto 2.5-3.0mtrs still expected, 8-10sec.

Tue/13 0000UTC to Wed/14 0000UTC

Wind: SSW-SSE 15-25kt gusty,
Sea: 1.5-2.0mtrs, upto 2.5mtrs possible (briefly) the more exposed you are, 5-7sec.
Swell: SW-SSW 1.5-2.0mtrs.Combined sea/swells of 2.5-3.0mtrs still possible, 8-9sec.
