SYNOPTIC DISCUSSION

THURSDAY 18thAPRIL 2024 – PM SHIFT

TONIGHT:

The most recent satellite data shows that the cloud band linked to the previously mentioned weather system is retreating westward, leading to an improvement in weather conditions. However, despite this retreat, the islands could still see periods of moderate rainfall due to the easterly winds and localised convections. As a result, the Heavy Rain Advisory that was previously issued for all land areas has now been lifted.

SATURDAY THROUGH THURSDAY:
A speed convergence zone is expected to approach the islands from the south tomorrow afternoon with minimal rainfall activities. Meanwhile, Easterlies will be predominant across the group, with fewer precipitation predictions by Saturday through the latter part of the outlook period. Therefore, mostly fine weather conditions, apart from some showers, are expected throughout the outlook forecast. However, we will keep monitoring the latest model updates for any weather changes and will be advised accordingly.

MARINE OUTLOOK:
The latest observations indicate waves now ranging below the advisory threshold, such was evident in the exit of the area of strong winds which drove the elevation of wave activities. Therefore, the Marine Advisory previously enforced for all marine waters is now cancelled. Moreover, the long-term wave predictions will fluctuate between 1.5 and 2 metres by Friday throughout the latter part of the outlook period. Furthermore, another surge of combined waves and swells is expected to move near the country’s coastline by Saturday next week.

ADVISORY/WARNING:

CANCELLED: MARINE ADVISORY
CANCELLED: HEAVY RAIN ADVISORY
