Fair to partly cloudy conditions are anticipated during the early parts of Monday, whereas occasionally cloudy skies with shallow isolated showers are likely during late afternoon. A tropical wave should begin to affect St Vincent & the Grenadines around late Tuesday night, generating cloudy to overcast skies. Some moderate to heavy showers are forecast for Wednesday as its associated low-level moisture and instability cross the island chain.
Breezy conditions will persist as the Atlantic high pressure system remains dominant. Moderate to strong (25km/h to 40km/h) trades will cross the islands, decreasing slightly in speed (20km/h-30km/h) around Tuesday before returning to strong again at times on Wednesday. An east south easterly flow is anticipated on occasions over the next 72 hours as well.
Sea conditions will remain moderate in open water with swells peaking at 1.5m on the western coasts and 2.0m on the eastern coasts. Slight conditions (1.0m - 1.2m) are possible on the western coasts early Tuesday, but by nightfall, moderate conditions are expected once more.
Haze intrusion across the islands is forecast to thin out around late Monday, but may increase ahead of the anticipated tropical wave early Tuesday night.
