Flags and pennants hoisted by the National Weather Service indicating unfavorable winds over 55 mph are known as?

The correct identification for flags and pennants hoisted by the National Weather Service that indicate potentially hazardous wind speeds exceeding 55 mph is known as a Storm Warning. This warning serves to alert individuals, particularly mariners and those in coastal areas, that severe weather conditions are imminent, making it crucial for them to take precautions.

A Storm Warning signifies that a significant weather event is on the horizon, typically involving severe winds that can lead to dangerous conditions, and is a higher level of alert compared to other warnings. In contrast, other options like a Hurricane Warning specifically relate to tropical storms that may bring sustained winds at or above 74 mph, while a Gale Warning refers to wind speeds between 34 and 40 knots (39 to 46 mph), which are less severe than those addressed in a Storm Warning. Small Craft Warnings are issued for smaller vessels at risk due to winds between 20 and 33 knots (23 to 38 mph), indicating conditions are not optimal for smaller boat operation.

Understanding these distinctions helps ensure that individuals are prepared for severe weather emergencies and can respond appropriately.
