Even if you aren’t in the storm’s path, it’s a good time to make sure you’re prepared with tips from the Naval Safety Center . Before
Be informed and know your hurricane terminology
Tropical depression: A system of clouds and thunderstorms with a defined surface circulation and sustained winds that do not exceed 38 mph.
Tropical storm: A system of clouds and thunderstorms with a defined surface circulation and sustained winds 39-73 mph.
Hurricane: A system of clouds and thunderstorms with a defined surface circulation and sustained winds 74 mph or higher.
Storm surge: An abnormal rise of water pushed ashore by a storm, over and above the predicted astronomical tide. Storm surges, which are often the greatest threat to life and property, are affected by a number of complex factors and can vary in magnitude despite hurricane categories. For example, Hurricane Katrina, a category 3 hurricane, had a storm surge of 28 ft., while Hurricane Charley, a category 4 hurricane, had a storm surge of 6-8 ft.
Storm tide: A combination of storm surge with normal tide, increasing the amount of water (e.g., a 15-foot storm surge with a 2-foot normal tide creates a 17-foot storm tide).
Hurricane/tropical storm warning: Hurricane/tropical storm conditions are expected within 36 hours in specified areas.
Hurricane/tropical storm watch: Hurricane/tropical storm conditions are possible within 48 hours in specified areas. Stay tuned to radio or TV for further information.
Short-term watches and warnings: Provide detailed information about specific threats during hurricanes, such as flash flooding or tornadoes. Understand the categorization of hurricanes Categorization adapted from the Saffir-Simpson Hurricane Wind Scale courtesy of the National Hurricane Center Category 1: Winds 74-95 mph, 64-82 kt, 119-153 km/h, very dangerous winds will produce some damage. Category 2: Winds 96-110 mph, 83-95 kt, 154-177 km/h, extremely dangerous winds will cause extensive damage. Category 3: Winds 111-129 mph, 96-112 kt, 178-208 km/h, devastating damage will occur. Category 4: Winds 130-156 mph, 113-136 kt, 209-251 km/h, catastrophic damage will occur, well-built framed homes can sustain severe damage with loss of most of roof structure and/or some exterior walls. Category 5: Winds exceeding 157 mph, 137 kt, 252 km/h, catastrophic damage will occur, high percentage of framed homes will be destroyed with total roof failure and wall collapse. Category 3, 4, and 5 hurricanes are considered “major hurricanes.” Understand conditions of readiness Tropical Cyclone Conditions of Readiness (TCCOR) are the Navy’s guidelines for estimating how long a region has and the actions necessary before it will be hit by destructive winds. Destructive winds are defined as winds of 58 mph or greater. At each TCCOR level, installations and tenant commands have set actions or checklists to complete prior to the storms arrival. These […]
