• After witnessing the continued decrease of involvement in the SpotterNetwork staff in serving SN members with troubleshooting issues recently, I have unilaterally decided to terminate the relationship between SpotterNetwork's support and Stormtrack. I have witnessed multiple users unable to receive support weeks after initiating help threads on the forum. I find this lack of response from SpotterNetwork officials disappointing and a failure to hold up their end of the agreement that was made years ago, before I took over management of this site. In my opinion, having Stormtrack users sit and wait for so long to receive help on SpotterNetwork issues on the Stormtrack forums reflects poorly not only on SpotterNetwork, but on Stormtrack and (by association) me as well. Since the issue has not been satisfactorily addressed, I no longer wish for the Stormtrack forum to be associated with SpotterNetwork.

    I apologize to those who continue to have issues with the service and continue to see their issues left unaddressed. Please understand that the connection between ST and SN was put in place long before I had any say over it. But now that I am the "captain of this ship," it is within my right (nay, duty) to make adjustments as I see necessary. Ending this relationship is such an adjustment.

    For those who continue to need help, I recommend navigating a web browswer to SpotterNetwork's About page, and seeking the individuals listed on that page for all further inquiries about SpotterNetwork.

    From this moment forward, the SpotterNetwork sub-forum has been hidden/deleted and there will be no assurance that any SpotterNetwork issues brought up in any of Stormtrack's other sub-forums will be addressed. Do not rely on Stormtrack for help with SpotterNetwork issues.

    Sincerely, Jeff D.

Looking over the information posted on the WFO DVN 4/13 tornadoes page, 'tornado #8' appears to have raked the same area only 45 minutes prior to the 915PM F1 tornado damage. Now that's what I call unlucky.
 
WoW! I have never heard of that before that is just wild! Has that ever happend before? This is the first time I have heard of it happening does anyone know?
 
Congrats on bagging your first tornado Sam!

Yes this has happened in the past but on a less notable level without that much time in-between. There have been 10 or so cases in the last 25 years where tornadoes with satellite vortices/tornadoes have hit buildings before the main funnel has passed.

I personally have never seen a report like the one you came across but then again I am not looking all that often so don't rely on me.
 
From the report Sam posted, this sounds like 2 separate tornadoes, not a satellite vortex type of situation.

I don't know about the same exact location being struck twice on the same day, but I can post this blurb, taken from Tom Grazulis' excellent book, Significant Tornadoes, 1680-1991 (see: Tornado Project Online)

Evnet #96
Apr 3 1974
Lawrwence, Morgan, Limestone, Madison Counties, Alabama
28 fatalities, 260 injured
F5
...The funnel passed across Wheeler Lake as a giant waterspout and entered Limestone County on a small peninsula. Here, it leveled a 3/4 mile-wide swath of trees. The reddish soil was dug up and plastered to the trees by the wind. A nearby mobile home park was damaged on the edge of the tornado, and an injured man was taken to a church. He died half an hour later when the church was destroyed by the second tornado to hit the area (see event #98)...

Event #98:
Apr 3 1974
Limestone, Madison Counties, Alabama; Lincoln County, Tennessee
22 fatalities, 250 injured
F4
Moved NE from just N of the TN River, 8mi SSW of Athens, just a half mile north of the track of event #96, which passed by a half hour earlier... Tanner, Capshaw, and Harvest were hit by both tornadoes... The tornado produced F3 or F4 damage for its entire path length...

If I'm not mistaken, I believe that this happened in Camilla, GA, back in 2000, with 2 F3s. However, I'm not sure if they hit common spots.

EDIT: They did overlap.

Also, the southern MI F4s (first one starting in Steuben Co, IN) on Palm Sunday '65 overlapped sometimes, other times the paths combining w/downdrafts to produce a 4 mile wide damage path.
