Daily email summary to staff and HQ My thanks to everyone for an outstanding job for an historic event. I have nothing but extreme kudos for our work during this event. For the second time in a couple of weeks, Jim Cantore (TWC) has specifically stated our graphicasts are the best he sees across the NWS and he uses them often. As far as where we stand, here is a quick summary. Tom Bradshaw is flying in Thursday night and will working out of our office for a few days. Since we are "ground zero", he will be feeding NWSHQ information directly, trying to help alleviate us doing the work. Two forecasters will be working shifts. Camp Parks, TLH, will work day shifts over the next few days (beginning with a K on Fri). KrissyScotten will be working midnights, beginning Saturday morning. This will allow us some flexibility for us to do surveys. Tim Marshall, who is used extensively by the NWS across the country for survey ratings of violent tornadoes, will be arriving at the office tomorrow morning and we will develop a game plan on the fly. John will be the post-event coordinator for the event and is setting up the teams for additional surveys. As far as media requests, I have attached talking points. Jody will post these on the WIKI page and let you know where they are located. They will be amended as new information occurs. You are welcome to give media interviews, but please do not stray from these talking points to keep everyone on the same page. If unsure, tell them to call tomorrow, or give them my GOVERNMENT cell number.
Summary ~88 % of all tornadoes EF0-1, ~11% are EF2-3 Most tornadoes are survivable “if” there are properly constructed shelters and actions taken This was a very rare, historic event, BUT… IT’S NOT A QUESTION “IF” IT WILL HAPPEN AGAIN, IT’S “WHEN” AND “WHERE”
