Reports indicate significant rainfall in the city of Castries and surrounding areas, with some flooding reported in the southern region. While the rain subsided for a brief period, conditions worsened by 5:00 p.m., as gloomy skies and rain persisted into the night.
The northern zone and other parts of the island were also affected by the heavy rainfall and thunderstorms.
As of October 6, forecaster Maclean Jn Baptiste predicted winds blowing from the east to east-southeast at approximately 20 mph (31 km/h), with occasional gusts. The forecast calls for generally cloudy weather with scattered light to heavy showers and isolated thunderstorms.
Residents and motorists in flood-prone and landslide-prone areas were advised to remain vigilant and exercise caution. The seas are expected to be moderate to locally rough, with waves and easterly swells ranging from 5 to 7 feet (1.5 to 2.1 meters).
Small craft operators and sea bathers should also be cautious due to the rough sea conditions.
Speaking to The VOICE on Tuesday, meteorologist Emmanuel Descartes reported that the tropical wave affecting the island was moving away, and weather conditions are expected to improve. He attributed the adverse conditions to “a little moisture and instability” contributing to the heavy rainfall and thunderstorms.
Descartes reassured residents that there is “no reason to panic” as improvements are anticipated in the coming days, but authorities urged Saint Lucians to continue exercising caution during this time.
In preparation for the 2026 Hurricane Season, Prime Minister Philip J. Pierre convened a meeting at the National Emergency Management Organisation (NEMO) Headquarters in June to review Saint Lucia’s readiness for the upcoming season. Key agencies and stakeholders provided updates on operational readiness, contingency plans, and available resources to ensure the protection of lives and property in the event of an emergency.
As the tropical wave continues to influence weather patterns, citizens are urged to remain vigilant, especially motorists traveling through areas susceptible to flooding where visibility may be reduced due to heavy rainfall.
The Meteorological Services have warned of possible localized flooding in low-lying areas and advise the public to monitor official updates closely.
The weather is creating potentially hazardous conditions at sea, impacting not only Saint Lucia but also the wider Lesser Antilles.
