Is there any kind of precedent for violent tornadoes in coastal cities? I feel like they are extremely rare (the recent New Orleans tornado nearly meeting the criteria).

Not violent, it's pretty difficult. From Mothers Day to Labor Day we really take on a fully tropical climate which lacks the wind aloft in sea breeze thunderstorms to put down anything. Also most stronger lows do not affect us as they go poleward as deepening occurs out of OK/TX in the winter and stay to the west of the Apps. It's certainly rare to see things line up, but when it does you have ample moisture to bring those LCL's down like yesterday

I was able to find two cases:

Galveston:https://www.tornadotalk.com/galveston-tx-tornadoes-september-12-1961/

Georgia: https://www.weather.gov/chs/TornadoOutbreak-May2008

There's a possible third in Tampa but I can't seem to find any info on it (I'm not counting the 1966 long tracker as F4 damage for that one was more inland).

 

There are others that are more inland (one West of New Orleans) but I decided to research only truly coastal locations.

One of the wildest tornado videos in history was that Myrtle Beach tornado that developed along a sea breeze front and roared directly down the beach in front of the high rises for miles. I think that was EF-2. Coastal fronts 9 times out of 10 wreck havoc on storms as they approach the beach and almost always cause them to be undercut and become outflow dominant. However, violent tornadoes and outbreaks like yesterday are exceptionally rare and the setup for discrete super cells like we saw yesterday out in the clear rarely materializes in that area. Really was likely a historic day yesterday but thank the lord it hit some of the least populated areas in the southeast. A really really close call with Columbia as well.

I would imagine there are quite a few similarities to a typical Carolina Alley outbreak, just further south.

Yea it’s the same in all the Carolina’s. NC has more issues with wedge fronts in the springtime and many times tornadoes set up along the wedge front which bolsters activity in the Triad area in some events though those are rarely strong tornadoes. Really I think the limiting factors are storm track is usually west of the mountains and a lot of energy is lost coming over terrain and we being further from the actual low centers then In the Deep South/Mississippi valley.

 The McIntosh County, GA, 2008 tornado damage is still very evident looking at the trees along I-95 near mile marker 50, which is just north of the GA 251 exit. The damage there is nearly 1/2 mile wide! (2,100 feet).

 Here’s a link showing some of the awful damage:

 https://www.southeasternphotography.com/Journalism/EF4-Tornado-hits-McIntosh/

  I’m thankful that I live in an area where violent tornadoes have only very rarely been within ~50 miles. This one in McIntosh County as well as yesterday’s in the Pembroke-Ellabell area are the only two I’m aware of off the top of my head. Of course, any tornado is dangerous. 
 
 Our bigger concern is obviously hurricanes, which themselves have produced many tornadoes in the area.

If 17 wasn’t such a damn mess this time of day I’d for sure drive to it. Also to the east of Moncks Corner is very sparsely populated forest

Frances Marion has some pretty good roads and some pretty bad ones. Not the place to be when it rains. It gets washed out quick in areas.

Honestly the bridges would be the best place to see it

Good luck with that anywhere this time of day  :lol:   Actually Hell Hole Road would be the perfect place to intercept. 

EDIT: You'd have to know the roads well in the forest though  ;)

Brett Adair in Sumter County Ga showing a TOG

Awesome video in my opinion because it shows so well what the "tightening of the couplet" looks like in real life. Rapid condensation occurring around the funnel at the LCL but a broad and general swirl in the cloud, yet intense rotation at the actual funnel itself. It's incredible how quickly the velocity of wind intensifies around a tornado, you go from a solid breeze at the inflow to insanity pretty quickly
