Understanding Tornado Categories: A Guide to Tornado Preparedness

Tornadoes are some of the most destructive natural disasters, capable of causing widespread devastation in a matter of minutes. Understanding the categories of tornadoes and their potential impact is crucial for effective preparedness. In this guide, we will explore the Enhanced Fujita (EF) Scale used to classify tornadoes, the characteristics of each category, and essential tips to stay safe.


Tornadoes can strike with little warning, making it vital to understand their classification and potential damage. The Enhanced Fujita (EF) Scale categorizes tornadoes based on their wind speeds and the severity of damage they cause. In this article, we will break down the EF Scale, providing insights into each category and how you can prepare to protect yourself and your loved ones.

Tornado Categories Breakdown:

  • EF0 (65-85 mph): EF0 tornadoes are the weakest, with wind speeds ranging from 65-85 mph. They cause minor damage, such as broken branches, shallow-rooted trees uprooted, and minor roof damage. Preparation includes securing outdoor items and staying informed about weather alerts.
  • EF1 (86-110 mph): With wind speeds of 86-110 mph, EF1 tornadoes can cause moderate damage. They can uproot trees, flip mobile homes, and cause more significant roof damage. Ensure you have a safe room or basement to take shelter in and keep an emergency kit ready.
  • EF2 (111-135 mph): EF2 tornadoes have wind speeds of 111-135 mph and can cause considerable damage. They can tear off roofs, demolish mobile homes, and snap or uproot large trees. It's crucial to have a well-constructed storm shelter and an emergency plan in place.
  • EF3 (136-165 mph): With wind speeds of 136-165 mph, EF3 tornadoes can cause severe damage. They can destroy entire stories of well-constructed houses, overturn trains, and uproot most trees. Immediate action to reach a safe shelter is necessary during such events.
  • EF4 (166-200 mph): EF4 tornadoes have wind speeds of 166-200 mph and can cause devastating damage. They can level well-constructed houses and toss vehicles through the air. Only underground shelters or reinforced safe rooms provide adequate protection against EF4 tornadoes.
  • EF5 (Over 200 mph): EF5 tornadoes are the most severe, with wind speeds exceeding 200 mph. They cause incredible damage, completely leveling buildings and stripping bark from trees. Survival depends on having an underground shelter or a specially designed tornado safe room.
