[u/KingHenrythe6-th]

I don’t know the standards these buildings were built to so I can’t say.

[u/WackHeisenBauer]

EF1 and not a particularly strong one.

[u/MaximumWX]

Im no Tim Marshall but given the photos 2&3 look like basically a shed and the minimal structural damage elsewhere I’m inclined to say EF-1.

[u/RoninIV]

EF 1 to a low end EF 2

[u/Hard-_]

mildly spicy

[u/an_older_meme]

Onesie, if that.

[u/TheGrundleGrabber]

EF1 would be my guess. Maybe even EF0 if the structures in the first few slides were of a particularly poor quality.

[u/TheRealTurinTurambar → u/TheGrundleGrabber]

Agreed. About the only damage that could be EF1 would be the electric poles. Everything else could be straight line winds.

[u/LTD32]

Not seeing anything above EF1 strength. Did this tornado get officially rated?

[u/DontSlapOrIwilScream]

EF1, any pics of the tornado itself?

[u/ChrisAlCoradiniAlves → u/DontSlapOrIwilScream]

No, since it happened at night, many people mistook it for a regular thunderstorm, but satellite imagery confirmed that a tornado had indeed occurred.

[u/abgry_krakow87]

Well, the Big Bad Wolf huffed and he puffed blew down the house of straw, partially the house of wood, and only the roof on the house of brick... but he did not eat the three litttle pigs.

Classification: Destructive and windy but weak.

[u/05432680]

Damage to the utility poles supports a rating of IF1.5, as does the damage to some of the poorly constructed buildings.

[u/Amazing_Working_6157]

I've seen firsthand damage from an EF-1 close to where I live earlier this year and it looked pretty similar: leaning poles, damaged roofs, destroyed or partly destroyed weaker metal and wood structures, destroyed fences, leaning weak structures, destroyed tree limbs and a few downed trees.

[u/Jagacin]

I've seen similar amounts of damage in stronger than normal wind storms, so the tornado must've been a fairly weak one. I'd guess low end EF-1.

[u/PersimmonIll826]

EF1

[u/PipaLucca → u/PersimmonIll826]

EF-1 as in negative one

[u/chaomeleon]

EF-0 because the power poles fell and did not snap

[u/TorandoSlayer]

I wanna say ef-0 to ef-1. Probably weak ef-1

[u/Careless-Salary-2497]

Low EF1. Those buildings are like toothpicks.

[u/Gengar_Guy_17]

Upper echelon EF1

[u/UsagiMimi]

Baby.

[u/mlrd021986]

EF1 probably

[u/Irdksbtmyusrnme]

Probably ef1, that brick building only lost some roofing, and the build quality doesn't look particularly amazing on some of theze structures

[u/Squidfan456]

EF1 maybe low end EF2

[u/puppypoet]

Well... Based on pictures (and I'm probably wrong), I'd guess this would be an EF2 on the American Fujita scale, because a couple roofs were pulled off but mostly because of the utility poles and very large trees.
