Weather outlook: There are scattered showers across our area, ahead of the approaching tropical wave. The relatively dry axis should cross our area this evening, but moisture behind the axis should bring scattered showers overnight into Friday. Isolated thunderstorm activity is possible by late Friday with a trailing trough.
Few isolated showers are possible Saturday and Sunday as weak shearline features associated with a broad area of low pressure, propagate across the islands.
The broad low pressure system is about 1380 miles away from the Lesser Antilles continues to produce a large area of disorganized showers and thunderstorms. Gradual development is possible for the next day or so while the system moves west-northwestward at 10 – 15 mph across the central tropical Atlantic Ocean. Conditions are forecast to become more conducive for development with a high (70%) chance of a depression just east of the Lesser Antilles during Saturday. The system could be near Tropical depression/strong tropical wave strength as it approaches the island chain on Monday…. Persons across the Lesser Antilles should be Alert! This system is being closely monitored for any development near the island chain.
Moderate surface winds (20 – 30 km/h) from the north-east should continue this afternoon. Wind speeds should gradually decrease to gentle during Friday…
Sea conditions are slight to moderate in open water with easterly swells… No dust concentrations are expected, but occasional thin patches may be noticeable on our horizon over the weekend.
