As the summer season brings warmer temperatures, changing weather conditions, and increased outdoor activity, it is important for all members of the Trent University community to stay informed and prepared.
Lightning is one of the most dangerous weather hazards in Canada, causing more fatalities than hail, wind, rain, and tornadoes combined. While lightning strikes are rare, they can pose serious risk, particularly for individuals who work, study, or participate in activities outdoors.
Most lightning-related incidents occur between June and August, often affecting people in open spaces or those sheltering under trees.
Know the Signs
Thunderstorms can develop quickly, especially during the summer months.
- If you can hear thunder, you are close enough to be struck by lightning.
- Lightning can strike up to 16 kilometres away from a storm.
- A loud crack of thunder indicates lightning is nearby.
- Darkening skies, increasing winds, and distant thunder are signs to seek shelter immediately.
When Thunder Roars, Go Indoors
The safest place during a thunderstorm is a fully enclosed building with electrical wiring and plumbing and/or fully enclosed metal-roofed vehicle with windows closed.
Avoid unsafe shelters such as:
- Tents
- Picnic shelters
- Dugouts
- Carports
- Greenhouses
- Sheds and other small structures
Remain sheltered for at least 30 minutes after the last sound of thunder.
If You Are Caught Outdoors
If no suitable shelter is available, move away from trees, poles, fences, water, and metal objects. Seek lower ground such as a ditch or valley while remaining aware of potential flooding and spread out if you are in a group. Do not lie flat on the ground.
High Winds
High winds may be the result of a storm, hurricane, tornado or other weather event. Hazards could include:
- Dust or debris causing eye injuries
- Wind-blown objects
- Falls
- Breaking of branches or uprooting of trees
- Broken power lines
- Reduced visibility
- Wildfire spread
In the event of high winds,
- Stop work that becomes too dangerous due to high winds
- Secure equipment, tools, or materials
- Take shelter and stay indoors.
- If you cannot find shelter, move to an area where you will be less likely to be hit by falling trees or power lines.
- Use buildings or vehicles to avoid wind.
