Tornadoes - June 2019

This analysis is based on preliminary data available from the Storm Prediction Center. Final tornado counts published by the Storm Prediction Center and NCEI's Storm Events Database might differ from this report. For a more detailed climatology, please visit our tornado climatology page.

According to data from NOAA's Storm Prediction Center, during June, there were 202 preliminary tornado reports. This is below the 1991-2010 average of 243 tornadoes for the month of June. Many of the June tornadoes occurred throughout the month in counts of 10 or fewer tornadoes per day. The most notable tornado event of the month occurred during June 15 and 16, in which 45 confirmed tornadoes developed across Illinois and Indiana with scattered tornadoes across the surrounding states. There were no reported deaths for this event. A second notable tornado event occurred on June 5 and 6, as 25 confirmed tornadoes were reported. The majority of these tornadoes were clustered in southern Louisiana. Several injuries but no deaths were reported.

Tornado Count

Final monthly tornado counts are typically less than the preliminary count. This can be due to some phenomena being inaccurately reported as tornadic activity or a single tornado being reported multiple times. Tornado accounts are reported to the local National Weather Service forecast offices who are responsible for going into the field and verifying each tornado reported. This process often takes several months to complete. Once all reports have been investigated, the final count is published by the Storm Prediction Center.

The monthly climate reports are written using the preliminary numbers because the final data is not available at the time of production. Historically, for every 100 preliminary tornado reports, at least 65 tornadoes are confirmed. An error bar is depicted on the tornado count graphic representing this uncertainty in the preliminary tornado count.
