An area of wind, known as a trough system, has moved past Vanuatu this week, causing unsettled weather across parts of the country.
According to Ellen Luke from the Vanuatu Meteorology and Geo-Hazards Department (VMGD), the trough has now shifted west of Fiji, but its impact continues to be felt, especially in southern parts of the country, including Efate and Tafea Province.
“Marine warnings are still active across the group,” Ms. Luke said. “We are expecting south-west winds to gradually shift to a more southerly direction this afternoon, then turn south-east tonight. Wind speeds today remain between 21 to 25 knots, causing rough seas with wave heights reaching up to 2.5 meters.”
An inland wind warning has also been issued, particularly for Tafea, where people are advised to take precautions.
“We’re warning people to be careful with strong winds inland. Dry branches, loose roofing, or objects not tied down could fall or fly. Please avoid staying under coconut trees during this time,” Ms. Luke added.
The bad weather affecting the south is expected to ease by tomorrow morning, while other parts of the country should begin seeing improved weather conditions from later today.
Tonight, residents should expect cooler temperatures due to changes in weather patterns. A new high-pressure system is pushing cold air up from the south, which will bring cooler air over the islands.
“This evening, Vanuatu will feel a drop in temperature due to a high-pressure system pushing cool air over the islands,” Ms. Luke explained. “Expect tonight to feel a bit colder than usual.”
In addition, the northern parts of the country may experience some rain early next week as another trough system approaches.
“A new band of rain associated with another trough system is expected to move across Vanuatu by early Thursday morning,” she said. “It’s not a cyclone threat, as cyclone season ended in April, but troughs and high-pressure systems can still bring strong winds and cooler temperatures.”
