The Thomas Jefferson National Accelerator Facility will conduct the monthly test of its tornado warning siren at 10:30 a.m. on Friday, Feb. 5. Depending on weather conditions at the time of the test, the siren could be heard by anyone within a 1.5-mile radius of the lab.
The test will be carried out over a period that could last up to three minutes. The test will be of the wavering tone (also called high-low-high or 10-4-10).
