Description:"This report provides climatological summaries and maps for tornadoes in the United States, with specific information concerning tornadoes during 1998-1999. The years 1998 and 1999 were quite active for tornadoes in the U.S., with well-above average numbers of fatalities. It is interesting to note that the winter-spring of 1998 was dominated by El Nino conditions, while the winter-spring of 1999 was dominated by La Nina, thus showing that active tornado seasons may occur in either situation. However, the 1998 season was much more active in the southeast, while 1999 saw a shift of activity farther west very much as expected. Also, these 2 years produced a total of 3 tornadoes of F5 intensity and 11 tornadoes of F4 intensity, for a total of 14 in the violent F4-F5 category"--Introduction.
