This is a high-risk outlook.
A 60 percent tornado outlook would mean that the SPC anticipates an extremely intense tornado outbreak with multiple violent tornadoes. Only one such outlook has been issued. It was on April 7, 2006. The event was far less severe than anticipated.

What does the 2 percent tornado probability from the spc typically mean?
A 2 percent tornado probability typically means that isolated and probably weak tornadoes are possible.
What does the 30 percent tornado probability from the spc typically mean?
This qualifies as a high-risk outlook. A 30 percent tornado probability typically means that the Storm Prediction Center anticipates a major tornado outbreak with the potential for multiple long-track and violent tornadoes.
What does the 45 percent tornado probability from the spc typically mean?
This qualifies as a high-risk outlook. Such an outlook generally means that the SPC anticipates a major tornado outbreak with the potential for multiple long-tracked and violent tornadoes. Since the SPC started publishing outlooks online in 2003, only four days have featured 45% or greater tornado outlooks.
What does the 5 percent tornado probability from the spc typically mean?
It can vary considerably as the is a fair degree of uncertainty. Usually it will mean a few scattered and mostly weak tornado will occur. Tornadoes stronger than EF2 are probably unlikely, though there are exceptions. This qualifies as a slight risk outlook.
What does the 15 percent tornado probability from the spc typically mean?
This qualifies as a moderate risk outlook. A 15 percent tornado probability outook can have a variable meanin due to uncertainty inherent in such forecasts. However, they may often predict moderate tornado outbreaks and sometimes major outbreaks. In such cases strong tornadoes are not uncommon and there is sometimes potential for violent tornadoes. As with other outlooks, some systems are far less severe than anticipated.

What does the 45 percent severe wind probability from the spc mean?
If the Storm Prediction Center (SPC) issues a 45% probability of severe wind for any specific location, it means that there is a 45% chance of a wind gust of at least 58 mph within 25 miles of that location. This may seem like a low number, but relative to a typical day it is quite high.
Has the 60 percent Tornado risk from the SPC ever been used?
The 60 percent tornado risk from the Storm Prediction Center (SPC) is used to highlight areas with a higher likelihood of tornadoes within a specific severe weather outlook. It is based on meteorological data and modeling, and it serves as a tool for emergency preparedness and response by indicating where the greatest tornado risk exists.
Why are tornado watches issued in 5 percent tornado areas from the SPC?
A 5% risk area for tornadoes suggests an environment fairly favorable for tornado development, enough to warrant a slight risk outlook. Such conditions are sometimes favorable enough to warrant a tornado watch.
What does silver hallmark SPC mean?
"SPC" Stands for Silver Plated Copper.
What does the 10 percent tornado probability from the spc typically mean?
Such an outlook is categoriezed as a slight risk. Tornado activty in such an instance can vary quite a bit as such outlooks come with a high degree of uncertainty. To a large degree what is likely to happen depends on the area covered. Such outlooks often indicate a few tornadoes, some of which may be strong, can occur, especially if there is a hatched area included. In some cases a moderate tornado outbreak may occur. Sometimes there is potential for one or two violent tornadoes. Again, though, as there is a high degree of undertainy in many cases, sometimes the forecast tornadoes fail to develop.
Has there ever been a tornado watch in a 2 percent tornado threat area from the SPC?
Yes. The most recent instance was on March 29, 2014. A tornado watch was issued for part of North Carolina event though it was only within the 2% area for tornadoes. Two tornadoes touched down within this watch area.
