Which weather warning signal indicates winds of 48 knots or more?

A Storm Warning is issued when there are forecasted winds of 48 knots (approximately 55 miles per hour) or more. This warning indicates that severe weather conditions are imminent or occurring, which can pose significant risks to vessels on the water.

Understanding the meaning of different weather warnings is crucial for the safety of boaters. A Gale Warning is issued for less severe winds, specifically between 34 to 47 knots, while a Small Craft Advisory warns smaller vessels of potentially hazardous conditions but does not specify the extreme wind speeds associated with a Storm Warning. A Hurricane Warning pertains to conditions related to a hurricane, which involve not only high winds but also storm surges and heavy rains, but it specifically signifies the approach of a hurricane.

Thus, the Storm Warning is the key signal that alerts mariners to take serious precautions due to extremely high winds that can lead to dangerous boating conditions.
