It's only there because the guy who invented the scale (Dr. Tetsuya Fujita) decided to put that letter there because it's his initial of his last name, "Fujita".

The EF scale for tornado intensity uses the "F" to denote the Fujita scale, named after Dr. Tetsuya Theodore Fujita who pioneered the scale. The scale ranges from EF0 to EF5, with higher ratings indicating stronger tornadoes based on estimated wind speeds and resulting damage.
EF on the tornado scale stands for Enhanced Fujita scale. It is used to classify tornado intensity based on the damage caused by the tornado, ranging from EF0 (weakest) to EF5 (strongest). The EF scale takes into account the strength of the wind and the type of damage observed.
The "F" in tornado ratings stands for "Fujita," referring to the Fujita scale developed by Dr. Tetsuya Theodore Fujita for classifying tornadoes based on their estimated wind speeds and damage caused. This scale ranges from F0 (weakest) to F5 (strongest), with F5 tornadoes having wind speeds exceeding 200 mph.
A tornado warning means that a tornado has been spotted or indicated by weather radar in your area. This is a time to take shelter immediately and follow safety precautions to protect yourself from the approaching tornado.
The debris and objects that were lifted by the tornado will fall back to the ground. Depending on the intensity of the tornado, the damage to buildings and structures can be severe. Recovery efforts, cleanup, and assessment of the affected area typically follow after the tornado dissipates.
The F-scale, a measurement used to categorize the intensity of a tornado, is measured on the Fujita scale based on the damage caused by the tornado. The scale ranges from F0 (weakest) to F5 (strongest) and is assigned after a thorough survey of the impacted area to determine the extent of damage to structures.
