What is indicated by a Hurricane Warning?

A Hurricane Warning indicates that dangerous conditions associated with a hurricane are imminent or already occurring in the specified area. Specifically, this warning is issued when sustained winds of 64 knots (approximately 74 miles per hour) or greater are expected within 36 hours. This classification serves as a crucial alert for individuals to take immediate protective measures, as these wind speeds can cause significant damage to structures, disrupt power, and create hazardous conditions on the water.

Understanding wind speed classifications is essential for proper preparation and response to hurricanes. The other options reference different wind speed ranges that are not associated with the severe implications of a hurricane. Winds between 34 and 47 knots might suggest stormy weather but do not meet the hurricane criteria. A wind speed of 50 knots also falls short of the threshold necessary for a hurricane warning. Winds below 18 knots indicate calm conditions, not warranting any warning at all. Therefore, recognizing the precise threshold of 64 knots is vital for assessing the seriousness of the storm and the required safety responses.
