Hazy conditions should continue this afternoon, inhibiting shower activity. However, an increase in low level moisture and instability should be noticeable across the islands from tonight, with Tropical Storm Kirk moving in on the Eastern Caribbean Islands. A Tropical Storm watch is in effect for St.Vincent and the Grenadines, and periods of rain, occasional moderate to heavy showers with gusty winds
are expected across our areafrom tonight. Wind speed strength could possibly reach storm force and conditions could deteriorate Thursday afternoon with haze gradually thinning out across our area. Persons in areas prone to flooding are advised to take precautions as rainfall accumulations 2 to 4 inches (50 - 100 mm) and possibly higher in mountainous areas. …. Instability should remain elevated on Friday as moisture associated with Kirk trails across the islands. A reduction in shower activity, cloudiness and wind speeds can be expected by late Friday.

Then gentle and occasionally calm conditions by midday with variable directions, becoming fresh to strong (35-50 km/h) by evening. A veering to southerly is expected Friday with Kirk passing to our north.

Barometric Pressure readings should be ranging 1009 mb - 1011 mb for the rest of today, falling to (1007- 1010 mb) by Thursday as Kirk crosses the islands. Readings should be rising on Friday. Sea swells are originating from the north-east with heights 1.5m – 2.5 m, further increase is expected by Thursday with easterly swells to peak near 2.0m on west and near 3.5 m on east coasts associated with Kirk. Late Friday, northerly swells generated by Post-Tropical cyclone Leslie, are expected to propagate southwards with swells 1.2 to 2.5 m (6 to 10 ft) on our northern and eastern coasts. Low-lying coastlines could be particularly vulnerable especially at times of high tide. Large waves and dangerous rip-tides can create unsafe conditions for small-craft operators, sea-bathers and other users of the sea. A High-Surf Advisory and Small-Craft Warning will be in effect from 6:00 pm Wednesday, 26th September, 2018 until 6:00 a.m Monday, 1st October.
