What wind speed defines a hurricane warning?

A hurricane warning is issued when sustained wind speeds reach 64 knots or greater. This classification signifies the potential for significant damage, destruction, and dangerous conditions, prompting people in the affected areas to take immediate action to ensure their safety.

The terminology used for weather warnings is standardized, and understanding these categories is vital for effective preparedness. A hurricane warning implies that hurricane conditions are expected within 36 hours in the specified area. This allows residents and authorities to react appropriately, minimizing risk and damage.

The other ranges of wind speeds provided in the options represent different levels of wind or storm alerts but do not fall under the hurricane warning category. For example, wind speeds of 34-47 knots indicate a tropical storm warning, not a hurricane, while lower wind speeds suggest less severe conditions altogether. Understanding this classification helps clarify the severity of the situation and the corresponding necessary precautions.
