Hurricane & Tropical Storm Guide: Safety & Preparation

Introduction

Hurricanes and tropical storms are powerful weather events that can cause significant damage and pose serious risks to life and property. Understanding these storms, their potential impacts, and how to prepare for them is crucial for anyone living in or visiting coastal areas. This guide provides comprehensive information on hurricanes and tropical storms, covering everything from formation and classification to safety measures and recovery efforts.

Understanding Hurricanes and Tropical Storms

What is a Hurricane?

A hurricane is a type of tropical cyclone, a rotating, organized system of clouds and thunderstorms that originates over warm tropical or subtropical waters and has a closed low-level circulation. Hurricanes are characterized by strong winds, heavy rainfall, and storm surge, which can cause widespread flooding and devastation. In the North Atlantic and Northeast Pacific, a tropical cyclone is classified as a hurricane when its maximum sustained wind speeds reach 74 miles per hour (119 kilometers per hour).

What is a Tropical Storm?

A tropical storm is a tropical cyclone with maximum sustained winds between 39 and 73 miles per hour (63 and 117 kilometers per hour). Tropical storms are less intense than hurricanes but can still cause significant damage due to heavy rainfall, strong winds, and potential flooding. Once a tropical cyclone reaches tropical storm status, it is assigned a name from a predetermined list to help with identification and tracking. — DP World Tour: Everything You Need To Know

How Hurricanes and Tropical Storms Form

Hurricanes and tropical storms form through a process that involves several key factors:

1. Warm Ocean Waters: Warm ocean waters (typically at least 80°F or 27°C) provide the necessary energy for these storms to develop. The warm water evaporates and rises, creating instability in the atmosphere.
2. Atmospheric Instability: Unstable atmospheric conditions allow the warm, moist air to continue rising, forming thunderstorms.
3. Low-Pressure System: A pre-existing low-pressure system or disturbance is required to initiate the development of a tropical cyclone. This low-pressure area draws in surrounding air.
4. Coriolis Effect: The Coriolis effect, caused by the Earth's rotation, deflects the moving air, causing it to rotate around the center of the low-pressure system. This rotation is counterclockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere.
5. Low Wind Shear: Low wind shear (minimal change in wind speed or direction with height) is essential for the storm to organize and intensify. High wind shear can disrupt the storm's structure and prevent it from strengthening.

The Saffir-Simpson Hurricane Wind Scale

The Saffir-Simpson Hurricane Wind Scale is a 1-to-5 rating based on a hurricane's sustained wind speed. This scale estimates potential property damage. Hurricanes reaching Category 3 and higher are considered major hurricanes because of their potential for significant loss of life and damage.

The categories are defined as follows:

• Category 1: 74-95 mph (119-153 km/h) - Very dangerous winds will produce some damage.
• Category 2: 96-110 mph (154-177 km/h) - Extremely dangerous winds will cause extensive damage.
• Category 3: 111-129 mph (178-208 km/h) - Devastating damage will occur.
• Category 4: 130-156 mph (209-251 km/h) - Catastrophic damage will occur.
• Category 5: 157 mph (252 km/h) or higher - Catastrophic damage will occur.

Understanding Hurricane Forecasts and Warnings

Hurricane Forecasts

Hurricane forecasts are issued by meteorological agencies, such as the National Hurricane Center (NHC) in the United States, to provide information about the predicted path, intensity, and potential impacts of a tropical cyclone. These forecasts are based on a combination of weather models, satellite data, and observations from aircraft and surface stations.

Hurricane forecasts typically include:

• Track Forecast: The predicted path of the storm's center over time.
• Intensity Forecast: The predicted maximum sustained wind speeds of the storm over time.
• Cone of Uncertainty: A graphical representation of the possible paths of the storm's center, based on historical forecast errors. The cone widens over time, reflecting the increasing uncertainty in the forecast.
• Discussion: A written summary of the forecast, including the reasoning behind the predictions and any uncertainties.

Hurricane Warnings and Watches

Hurricane warnings and watches are issued to alert the public about the potential threats from a tropical cyclone. Understanding the difference between a watch and a warning is crucial for taking timely action.

• Hurricane Watch: A hurricane watch is issued when hurricane conditions (sustained winds of 74 mph or higher) are possible within the specified area. A watch typically covers a broad area and is issued 48 hours before the anticipated first occurrence of tropical-storm-force winds.
• Hurricane Warning: A hurricane warning is issued when hurricane conditions are expected within the specified area. A warning is typically issued 36 hours before the anticipated first occurrence of tropical-storm-force winds. During a hurricane warning, it is crucial to complete your preparations and be ready to evacuate if necessary.
• Tropical Storm Watch: A tropical storm watch is issued when tropical storm conditions (sustained winds of 39-73 mph) are possible within the specified area within 48 hours.
• Tropical Storm Warning: A tropical storm warning is issued when tropical storm conditions are expected within the specified area within 36 hours.

Preparing for a Hurricane or Tropical Storm

Develop a Family Disaster Plan

A family disaster plan is a crucial step in preparing for a hurricane or tropical storm. This plan should outline how your family will communicate, evacuate, and shelter in place during a storm. Key components of a family disaster plan include:

• Communication Plan: Establish a way for family members to communicate with each other if separated. This may include designating a meeting place or identifying an out-of-state contact person.
• Evacuation Plan: Determine evacuation routes and destinations. Identify multiple routes in case one is blocked or congested. Have a plan for transportation, whether it's using your own vehicle or relying on public transportation.
• Shelter-in-Place Plan: If evacuation is not necessary or possible, develop a plan for sheltering in place. Identify a safe room or area in your home that is away from windows and exterior walls.
• Emergency Contacts: Create a list of emergency contacts, including family members, friends, neighbors, and local authorities.
• Practice Drills: Conduct regular drills to ensure that everyone in the family knows the plan and what to do in an emergency.

Assemble a Disaster Supply Kit

A well-stocked disaster supply kit is essential for weathering a hurricane or tropical storm. This kit should include enough supplies to sustain your family for several days, as it may take time for emergency services to reach your area. Essential items to include in your disaster supply kit are:
