Although predictions of seasonal hurricane activity have been issued
for years, there is no analogous system for predicting how active a
spring tornado season might be. By relating precipitation data from
rain gauges and satellites to a tornado database (1951–2006), the
authors find that drought conditions in fall and winter usually lead to
a below-average number of tornado days the following spring across
north Georgia.
