In the scope statement it is mentioned there is a strong possibility of a hurricane impacting the schedule at any given time. This notation would be considered a(n):

An assumption is a factor believed to be true for planning purposes without proof, not a potentially harmful future event with acknowledged uncertainty.

An issue is a problem or concern that has already occurred and requires immediate action, whereas a hurricane in this context is only a possibility.

A constraint is a limiting factor already imposed on the project (such as a fixed deadline or budget cap), not a future uncertain event.

A risk is defined as an uncertain event or condition that, if it occurs, has an effect on project objectives such as schedule, cost, or scope. A hurricane is a potential future event with an uncertain probability of occurrence that could delay the schedule, making it a risk by definition.
