St Kitts and Nevis Meteorological Forecast

This detailed weather forecast, valid until 8 PM on Wednesday, September 24, 2025, paints a picture of a region bracing for a period of significant rainfall and potential thunderstorms. Issued on September 23, 2025, the forecast highlights the influence of an active tropical wave traversing the area. This atmospheric disturbance is expected to amplify the likelihood of widespread showers and thunderstorms over the next 24 hours. The predicted rainfall accumulation, ranging from 25.4 mm to 76.2 mm (1 to 3 inches), suggests a moderate to heavy rainfall event, posing potential challenges for local infrastructure and daily activities. The forecast also provides specific details regarding temperature fluctuations, wind conditions, and sea state, offering a comprehensive overview of the anticipated weather patterns.

The forecast for the night of September 23rd predicts cloudy to overcast conditions, with showers expected and a moderate 60% chance of thunderstorms. This suggests a night characterized by persistent cloud cover and intermittent periods of rain, punctuated by the possibility of more intense thunderstorm activity. Residents should be prepared for potentially disruptive weather conditions overnight and take necessary precautions to ensure safety and minimize inconvenience. The combination of cloud cover and precipitation will likely contribute to a relatively humid and muggy night.

Looking ahead to Wednesday, September 24th, the forecast indicates mostly cloudy skies with a high 70% chance of showers and a moderate 40% chance of thunderstorms. This suggests that while the cloud cover will persist, the likelihood of showers remains high throughout the day. The slightly reduced chance of thunderstorms, compared to the overnight forecast, indicates a potential shift towards more consistent, widespread rainfall rather than isolated, intense storm cells. However, the possibility of thunderstorms still warrants attention and preparedness for potentially heavy downpours and associated risks, such as localized flooding and lightning strikes.

The forecast also provides crucial information regarding wind conditions and sea state. Winds are predicted to be from the southeast, blowing at speeds between 19 and 33 km/h (12 to 21 mph), with gusts reaching as high as 52 km/h (30 mph). These sustained winds, combined with the potential for stronger gusts, indicate the possibility of breezy to windy conditions, which could exacerbate the impact of the rainfall and contribute to a heightened sense of discomfort. The relatively strong winds will likely influence outdoor activities and may pose challenges for navigation and transportation, especially for smaller vessels.

Sea conditions are expected to be moderately rough, with wave heights ranging from 1 to 1.5 meters (3 to 5 feet). This increase in wave height, likely driven by the combination of wind and the passing tropical wave, suggests potentially hazardous conditions for marine activities. Boat operators and coastal residents should exercise caution and closely monitor weather updates before venturing out to sea. The rough seas could also contribute to coastal erosion and increase the risk of rip currents, further emphasizing the need for vigilance and preparedness.

Finally, the forecast provides the times for sunrise and sunset on Wednesday, September 24th. Sunrise is predicted for 6:01 AM, while sunset is expected at 6:06 PM. These timings offer a sense of the daylight hours available and can be useful for planning outdoor activities, though the predicted weather conditions may limit such opportunities. The relatively equal lengths of day and night reflect the time of year, approaching the autumnal equinox, when the day and night are roughly equal in duration across the globe.

In summary, this detailed weather forecast provides a comprehensive overview of the anticipated weather conditions for the next 24 hours, characterized by the influence of an active tropical wave. The forecast predicts significant rainfall, a moderate to high chance of thunderstorms, breezy to windy conditions, and moderately rough seas. Residents and visitors are advised to take necessary precautions to ensure safety and minimize disruptions caused by the anticipated weather. This includes staying informed about weather updates, securing loose objects that could be affected by strong winds, and avoiding unnecessary travel, especially by sea. The forecast underscores the importance of preparedness and vigilance in the face of potentially challenging weather conditions.
