There is not an awful lot to report this month. The extremely low level of tornadoes in August continued the pattern of the year so far.

According to data from the Storm Prediction Center, during August, there were 52 preliminary tornado reports. This is less than the 1991-2010 August average of 83 tornadoes, and once the final tornado count is confirmed, the August 2012 number could be revised lower. This marks the least active August since 2003, in terms of the number of tornadoes reported, when 44 tornadoes were confirmed. The majority of the tornadoes during the month were weak and associated with Hurricane Isaac as it traversed the Florida Keys and made landfall along the Louisiana coast at the end of August. The below average tornado activity during August is similar to the rest of 2012 to-date. The preliminary number of tornadoes during the January-August 2012 period was 800, including 76 tornado confirmations still pending for July and August, marking the lowest January-August tornado count since 2002.

Figure 1, which gives provisional information right up to date at 25th September, shows, on a year to date basis, tornadoes running at 71% of normal.

 

I was hoping to include the actual confirmed data for May by now, but NOAA still do not have it available, so I will be reporting on this next month, hopefully with June’s data as well.

 

In the meantime, a little quiz. Which state has had most tornadoes between 1991 and 2010, relative to its area?

 

P.S. Please remember all monthly tornado reports can be accessed on the Tornado Category on the top bar. I now have a full database of every tornado since 1970, so if anybody has a specific request for information, please let me know, and I will do my best.
