Quick Answer
A safe distance to move away from a storm varies depending on its severity, but as a general rule, it's recommended to be at least 1 mile away from the storm's edge, and at least 3 miles from the storm's center if possible.
Understanding Storm Danger Zones
When dealing with a severe storm, it’s essential to understand the different danger zones. The storm’s edge, or outer rain band, is typically the most unpredictable and prone to rapid changes in wind speed and direction. This is where lightning strikes are most common. Moving away from the storm’s edge is crucial to avoid being caught in the midst of a lightning storm.
Calculating Safe Distances
To calculate a safe distance from the storm, you can use the “30-30 rule.” If you see lightning, count the time between the lightning flash and the thunder. If the time is 30 seconds or less, the storm is within a 1-mile radius. If the time is 30-60 seconds, the storm is within a 2-mile radius. If the time is over 1 minute, the storm is at least 3 miles away. Another method is to use the “flash-to-bang” technique: if the time between the lightning flash and the thunder is 5 seconds or less, the storm is within 1 mile. This method works best if you’re in a rural area with minimal background noise.
Preparing for the Worst
While moving away from the storm is crucial, it’s equally important to prepare for the worst. If you’re caught in the open during a lightning storm, crouch down low with your feet together, and your head down. Avoid standing near tall objects such as trees or power lines, as these can attract lightning. If you’re in a vehicle, stay away from windows and doors, and avoid metal objects such as seatbelts or the steering wheel. If you’re indoors, stay away from windows and doors, and avoid using water or taking showers, as these can conduct electricity.
