Another Below Average Year For US Tornadoes
By Paul Homewood
Provisional data from the Storm Prediction Centre shows that the number of tornadoes in 2015 finished well be low average for the fourth year running, though higher than the last three years.
Local storm reports (LSRs) are always higher then final tornado counts, because of duplication, counting of non tornado events, etc. Final confirmation of tornadoes and EF’s categories takes about three months, but there were 948 confirmed tornadoes up to the end of September, and NOAA estimate a full year total of 1150.
Significantly, there were few strong tornadoes in 2015, with one EF-4 confirmed in April, and two more provisional in December. There were no EF-5’s at all, the strongest category.
Full analysis will be available in March.
