very good question. the terrain of the area would not support any sort of enhanced wind speeds. i am not sure you could have such a narrow straight line wind damage event... but who knows. im sure its happened before. what storm processes could have such narrow wind damage?-when terrain doesnt appear to be an issue?Originally posted by Steven Williams
How narrow a damage trail could straight line winds do?
Shane, it is accepted practice (although not always followed) to rate conservatively, and then look for evidence that it may have been worse. Tim Marshall says, "Sometimes the evidence is in what was not damaged" in reference to things like "sliders".Originally posted by Shane Adams
I don't get why it's policy to assume it's not a tornado if the evidence is inconclusive. Who decided that straight line winds get the automatic nod without overwhelming edvidence to the contrary?
