Tropical Weather Update - October 19, 2025

Near the Windward Islands and the Caribbean Sea (AL98): Recent satellite wind data and surface observations indicate the tropical wave (Invest 98L) currently crossing the Windward Islands still lacks a closed circulation. However both radar and satellite images indicate the associated shower and thunderstorm activity is starting to show signs of organization. The system is still moving quickly westward at 20 to 25 mph and environmental conditions are forecast to become more favorable as it slows down in the central Caribbean Sea by the middle of this week. A tropical depression is likely to form by the middle to latter portion of this week in the central Caribbean Sea.
