A broad area of low pressure is expected to form over the southwestern Caribbean Sea during the next day or so from a tropical wave currently located over northwestern Colombia and the south-central Caribbean Sea. Environmental conditions are forecast to be conducive for development, and a tropical depression is likely to form late this week or over the weekend while the system moves west-northwestward to northwestward over the northwestern Caribbean Sea.
This system could develop into a hurricane over the western Gulf of Mexico by early next week.
