What is a Class 0 tornado?
What is a Class 0 tornado?
EF-0 tornadoes are considered ‘weak’ and usually pack winds around 105 and 137 kilometres per hour. Typical damages include the loss of shingles, gutters, awnings, or metal siding. Shallow trees may fall over, and large trees could lose branches, potentially leading to downed power lines and outages.
How bad is a EF 0 tornado?
The Enhanced Fujita Scale or EF Scale, which became operational on February 1, 2007, is used to assign a tornado a ‘rating’ based on estimated wind speeds and related damage….The Enhanced Fujita Scale (EF Scale)
| EF SCALE | |
|---|---|
| EF Rating | 3 Second Gust (mph) |
| 0 | 65-85 |
| 1 | 86-110 |
| 2 | 111-135 |
What is the lowest level tornado?
Tornado Classification
| Weak | EF0, EF1 | Wind speeds of 65 to 110 mph |
|---|---|---|
| Strong | EF2, EF3 | Wind speeds of 111 to 165 mph |
| Violent | EF4, EF5 | Wind speeds of 166 to 200 mph or more |
How strong is an EF 0 tornado?
EF0 Tornado Facts An EF0 tornado has wind speeds between 65 and 85 mph (105 and 137 km/h). Damage from an EF0 tornado is described as minor. In the United States, between Feb 1st, 2007 and 2017, there was 7,326 confirmed EF0 tornadoes.
What percentage of tornadoes are F4 or F5?
Tornadoes that are intense enough to warrant an F4/EF4 or F5/EF5 rating are classified as “violent.” Fortunately, these tornadoes are extremely rare, accounting for only about two percent of all tornadoes.
What are the 3 stages of a tornado?
The formation and life cycle of tornadoes can be explained in a series of stages:
- Stage 1 – Storm development. Sunshine heats the ground which in turn heats the air near ground level.
- Stage 2 – Storm organisation.
- Stage 3 – Tornado formation.
What should you know about tornado threat levels?
Threat levels depicted account for forecast errors and incorporate a reasonable safety margin. The threat levels depicted are meant to answer the following question: Given the latest information, what should I be planning for?
Which is the weakest category for a tornado?
The Enhanced Fujita Scale classifies storms from Category 0 to Category 5, with the top category reserved for only the most devastating and catastrophic storms. The Enhanced Fujita Scale contains six categories. The weakest, EF0 tornadoes, involve sustained winds between 105 to 137 kilometers per hour (65 to 85 mph).
How are tornadoes rated by the National Weather Service?

How are tornadoes rated on the Fujita scale?
To track and classify these storms, the National Weather Service bases tornado ratings on tornado wind speed and damage patterns to determine the intensity of the tornado. The Enhanced Fujita Scale classifies storms from Category 0 to Category 5, with the top category reserved for only the most devastating and catastrophic storms.
