What phenomenon does a "hurricane watch" signify?

A "hurricane watch" signifies that conditions are favorable for hurricane activity, indicating that there is a possibility of a hurricane developing or approaching an area. This alert serves as a way to warn residents and local authorities to prepare for the potential impact of a hurricane. While it does not guarantee that a storm will occur, it indicates that persons in the area should be vigilant and ready to take protective measures.

In contrast, a hurricane warning would indicate that hurricane conditions are expected within a certain timeframe, and it would require immediate preparation and action. The other options—such as hurricane force winds being expected, an official declaration of a hurricane, or an active hurricane in the region—do not accurately reflect the meaning of a "hurricane watch." These terms represent stronger alerts that come into play once a storm poses a more imminent threat.
