About EF1 Tornadoes

Wind Speeds: 86-110 mph (Enhanced Fujita) / 73-112 mph (Original Fujita)

Damage Characteristics: EF1 tornadoes represent moderate damage and comprise about 31% of all tornadoes. They mark the transition from light to significant structural damage potential.

Typical Damage: Roof surfaces peeled off, mobile homes overturned or badly damaged, exterior doors and windows broken, moving automobiles pushed off roads, attached garages may be damaged, and moderate damage to well-constructed homes.

Historical Context: Many notable tornado outbreaks include significant numbers of EF1 tornadoes that, while not the strongest, contribute substantially to the overall damage footprint of severe weather events.

Data Analysis

Monthly Distribution of EF1 Tornadoes

Monthly breakdown shows seasonality patterns and when EF1 tornadoes are most likely to occur.

Annual Trends of EF1 Tornadoes (1950-Present)

Yearly trends show how EF1 tornado frequency has changed over time, revealing patterns and potential climate influences.

Note: The apparent increase in weaker tornadoes over time is partly due to improved detection and reporting systems, not just climate factors.

Top 10 States for EF1 Tornadoes

Geographic distribution shows which states are most affected by EF1 tornadoes, highlighting tornado-prone regions.

EF1 Tornadoes by Decade

Distribution across decades shows long-term patterns and historical trends in EF1 tornado occurrences.

The increase in recorded tornadoes since the 1950s reflects both improved detection technology and possibly climate factors. Weaker tornadoes were often missed in early decades before modern radar and storm spotter networks.

Path Length Distribution of EF1 Tornadoes

Shows how far EF1 tornadoes typically travel, providing insights into their duration and geographic impact.

Fatality Distribution of EF1 Tornadoes

Shows the human impact of EF1 tornadoes, revealing what percentage caused fatalities and in what numbers.

Note: This chart uses a logarithmic scale to better show the distribution of fatalities, as most tornadoes cause zero deaths. Although most weak tornadoes don't cause fatalities, they can still be deadly when hitting vulnerable structures or populations.
