Marine advisory still in effect: Meteorology Division

The Samoa Meteorology Division has cancelled a strong wind advisory but warned that a marine advisory still remains in effect for all of Samoa.

The Meteorology Division advised in a marine severe weather information bulletin issued late Monday that their marine advisory remains in effect.

"The high-pressure system continuously migrates eastward while maintaining moderate to fresh Easterly winds over Samoa as well as wind and waves and swells of 2.5-3 meters," the bulletin reads.

According to the bulletin, observations by the Meteorology Division points to a decreasing trend of wave and swell activity, though they are predicted to conditionally increase towards the middle of the week due to the movement of another high pressure system.

"Therefore the previously issued wind advisory is now cancelled, though the marine advisory remains for all marine waters," the bulletin further states. 

Potential impacts of the forecast by the Meteorology Division include strong current and rough seas with fresh winds at times.

As for the forecast for the days ahead, the Meteorology Division says from Tuesday through to Sunday, global model prediction reveals a prolonged trade wind weather pattern for the week ahead.

"Winds may commence reduction during the beginning of the week. However, another high-pressure system centered further southwest may bring another surge of fresh and strong winds towards the end of the week.”

The Meteorology Division said its models have not indicated any major rain-maker synoptic system over Samoa, aside from brief wind-driven showers, particularly at windward locations and elevated areas.

They are also forecasting that the high-pressure system continues to migrate further southeast from Samoa while maintaining fresh winds over the country’s marine waters.

"Current waves observation as of this morning range from 2.5-3 meters diminishing. Therefore the marine Warning is now cancelled. Conditions may gradually ease later in the evening. 

“Wave-watch models and severe weather guidance products hinted at another set of swells to reach our marine waters midweek.”

The Samoa Meteorology Division is part of the Ministry of Natural Resources and Environment based at Mulinu'u.
