It may have been capable but I doubt it given that its short track over a fairly populated area. It certainly was violent though. There were frail buildings along its path for sure but reports and aerial photos indicate that the tornado leveled some fairly large and ostensibly well built homes as well.Incredible that 22 people were killed in the space of only 2 miles and likely a few minutes, I've head about this thing before and I do wish there were more high-quality photographs of its damage available; I can't help but wonder if this thing achieved F5 intensity but the construction material of the buildings it struck was likely dubious at best, so they couldn't go any higher than F4 with ranking it.
Ten members of the same extended family perished in the tornado as well. I think the area basically doubling or tripling in population due to Hilda, the erratic nature of hurricane spinups, and the time of day(630am) all contributed to the high fatality rate as well. Add in no basements and you've got a bad situation. Even today those circumstances and the violent nature of the tornado would make for a terrible end result.A death toll that high from such a brief tornado suggests that it was likely genuinely violent. That’s extremely impressive, and not to mention tragic.
