  • Hurricane Katia in the southwestern Gulf of Mexico has maximum sustained winds of 80kt near the centre and is moving slowly WSW towards southern Mexico.
  • Hurricane Irma now west of Inagua Islands has maximum sustained winds of 135kt and is moving WNW skirting the northern coast of Cuba towards southern Florida.

Typhoon Hato is one of the strongest tropical cyclones that hit Hong Kong and Macau in the past 20 years, triggering the highest Severe Typhoon Warning 10 from the Hong Kong Observatory.

The system started as a weak circulation over the NW Pacific well east of northern Philippines on 19th August 2017. It then intensified and moved WNW-NW crossing Luzon Strait on the 21st and the northern South China Sea on the 22nd. Typhoon Hato reached maximum wind speed of 80kt at 23/0300UTC before making its landfall at Macau at 0600UTC.

Typhoon Hato left casualties and massive destruction in its wake.

The Bureau of Meteorology has downgraded the ENSO Outlook from El Niño WATCH to INACTIVE.  The tropical Pacific Ocean El Niño Southern Oscillation  is likely to remain neutral for the second half of 2017.

According to BoM, the trade winds and Southern Oscillation Index are well within the neutral range.  All eight international models surveyed by the Bureau now suggest tropical Pacific Ocean temperatures are likely to remain ENSO-neutral for the rest of 2017.

Eni has started gas production from the Jangkrik Development Project in the deep water of Makassar Strait ahead of schedule. The project comprises the gas fields Jangkrik and Jangkrik North East.

Offshore Weather Services is proud to be the weather forecast service provider for Technip and Saipem during their operations in the Jangkrik Field.

Eric Chiong, Company Director and Senior Weather Forecaster came on board Posh Arcadia on July 4-13, 2017 for Saipem during the anchor cable replacement of the Floating Processing Unit (FPU) Jangkrik.

The cable replacement was challenged by recurring squalls over the Makassar Strait but the OWS in-house high resolution WRF models with spatial resolution of 1.1km and hourly temporal resolution greatly assisted Eric in determining the risk of squalls 36 hours ahead.

Offshore Weather Services would like to congratulate the Shanghai Salvage Company on the successful lifting of the ferry Sewol from the seabed off southwestern South Korea on March 23, 2017. The ferry capsized on 16 April 2014 en route from Incheon to Jeju in South Korea while carrying 476 passengers.

In a very complex and lengthy salvage operation made more difficult by the cold waters, strong ocean currents and adverse weather conditions the vessel was finally brought to the ocean’s surface suspended between two large barges supported by wires running through 66 hydraulic jacks. It was imperative that the Sewol be brought to the surface without further damage and this was successfully achieved.

The stricken vessel will now be transported to Mokpo in South Korea where a search will be made for missing bodies and the cause of this tragic accident.

Offshore Weather Services are proud to have provided the weather forecast service to Shanghai Salvage for the entire salvage operation.

The latest ENSO Wrap-up issued by the Bureau of Meteorology (BoM), Australia on 14 February 2017 indicates that the El Niño-Southern Oscillation (ENSO) remains neutral with virtually all indicators close to their average values.

Either neutral or El Niño are considered the most likely ENSO state for the southern winter and spring. Model outlooks indicate a neutral IOD is likely through late autumn and early winter.
