NCDC added Alaska climate divisions to its nClimDiv dataset on Friday, March 6, 2015, coincident with the release of the February 2015 monthly monitoring report. For more information on this data, please visit the Alaska Climate Divisions FAQ.
According to data from the Storm Prediction Center, during April, there were 83 preliminary tornado reports. This is well below the 1991-2010 average of 155 for the month, and marked the slowest April in terms of tornadoes since 1992. The last April with fewer than 100 tornadoes was in 1993. April is typically one of the more active tornado months, with annual tornado activity peaking in May and June. The below-average tornado activity during March and April has contributed to a below-average tornado count for the year-to-date period. For January-April, 114 tornadoes have been confirmed with 101 tornado reports still pending for March and April. The 1991-2010 average tornado count for January-April is 300.
