Tornadoes in/around the Lake Anna Area are quite rare. Only 41 confirmed touchdowns have been documented since 1950. Most tracks are fairly short (less than 2 miles). The longest track (22.2 miles) is one of the earliest documented tornadoes that moved from near Lake Louisa to Partlow in 1962. Due to the sparse population, cities & towns, dollar losses are relatively low.
There have been no deaths and two injuries from these tornadoes.
Most tornadoes occur between the months of May through September, with May having the most tornadoes. We can get tornadoes in the winter, but they are quite rare.
Tornadoes are rated on the EF-Scale (before 2010 it was the F-Scale). The F-Scale was developed by Dr. Ted Fujita after years of tornado damage analysis. The scale was changed to the EF-Scale (E=Enhanced) after more thorough research into tornado damage. The strongest tornado for the Lake Anna area has been an F3 in Orange County, in 1990.
The biggest outbreak was on 9/17/2004 when the remnants of Hurricane Ivan moved through Virginia with a record 58 tornadoes. Five of these tornadoes crossed Orange/Louisa & Spotsylvania counties.
