Nope.
If it was, there would be no questions about where on the EF scale a storm scored.....but the scoring is always done post-storm by experts on the ground after damage surveys.
When they did the damage surveys after the North Carolina tornado outbreak in 2011, I remember the arguments people had about whether this one was an EF2 or that one was an EF3...didn’t seem to make a whole lot of difference given that peoples’ homes were just as flattened regardless, but I guess for research and posterity these things have to be done.

The question was windspeed, not force. That’s going to depend on the size of the storm and how much debris it picked up as well as wind speed.
