Waterspout : What It Is and How to Respond
Imagine a calm day on one of Canada’s stunning lakes, an ideal setting for a day of boating or fishing. Out of nowhere, a funnel-shaped cloud begins to descend, twisting as it touches the water below. This remarkable, yet hazardous, phenomenon is known as a waterspout.
For anyone who enjoys Canada's vast coastlines and tranquil inland waters, knowing how to stay safe when a waterspout occurs is essential. This guide will explain what a waterspout is, how to react, and offer tips on how to prepare for these powerful weather events to ensure your safety.
What Exactly Is a Waterspout?
To know how to respond to a waterspout, it’s important to first understand what it is. In simple terms, a waterspout is a rapidly rotating column of air that forms over a body of water. It’s essentially a tornado that occurs over water. The visible funnel consists of condensed water vapor, while the base is made up of water spray lifted from the surface.
The Main Types of Waterspouts
In Canada, the most common type of waterspout is the fair-weather waterspout, which typically forms under calm, non-stormy conditions. These waterspouts develop from the water's surface and, although impressive, are generally weaker and shorter-lived than tornadoes.
While they can still pose a risk, they are far less dangerous than their more severe counterparts. The tornadic waterspout, on the other hand, is significantly more threatening. These waterspouts are essentially tornadoes that form over or move across water and are closely linked to severe thunderstorms. Accompanied by powerful winds, intense lightning, and heavy rainfall, tornadic waterspouts can be far more destructive, making them a serious concern for anyone in their path.
Difference Between a Waterspout and a Tornado
Although a waterspout is a form of tornado, it’s important to understand the distinction to gauge the level of threat it presents. While both share similar characteristics, the conditions under which they form and their overall intensity can vary greatly, especially when compared to the far more destructive force of a 1912 tornado in Saskatchewan. Recognizing these differences is essential for accurately assessing the risk and knowing how to respond appropriately.
| Feature | Waterspout | Tornado |
|---|---|---|
| Formation Location | Over a body of water (lakes, oceans) | Over land |
| Typical Formation | Often forms from the water upward, often in fair-weather conditions | Almost always forms from a severe thunderstorm (supercell) |
| Strength & Wind Speed | Generally weaker (EF0-EF1 equivalent), but can be strong. | Can range from weak to catastrophic (EF0-EF5), with wind speeds over 300 km/h. |
| Parent Cloud | Can form from cumulus clouds in fair weather or from thunderstorms | Almost always forms from a severe thunderstorm |
A key point to understand is that a tornadic waterspout can be just as dangerous as a land-based tornado. However, it’s important to note that even the more common fair-weather waterspouts should not be underestimated or taken lightly, as they still pose a significant risk.
Are Waterspouts Dangerous?
Yes, waterspouts are indeed dangerous.
While most waterspouts in Canada tend to be weaker, their rotating winds can easily surpass 100 km/h. This level of force is more than enough to capsize or damage boats, injure or even kill people, and pose a significant threat to shoreline areas if they move onto land and become tornadoes. For these reasons, it’s crucial to treat every waterspout as a serious threat, regardless of its strength.
When and Where Do Waterspouts Occur in Canada?
Canada’s expansive coastline and numerous lakes create an ideal environment for waterspouts to form. Being aware of when and where they are most likely to occur can help you plan your activities with safety in mind.
Typical Seasons in Canada
In Canada, the waterspout season typically spans from July to October. During this period, the large bodies of water are warm enough to supply the moisture and heat required for these phenomena to develop, while cooler air higher in the atmosphere creates the instability needed to trigger rotation. The peak of the season generally occurs in late summer, from August to September.
Common Regions for Waterspouts
Waterspouts can form on any sufficiently large body of water, but certain regions in Canada are especially known for their frequent occurrence:
The Great Lakes: Lake Erie and Lake Ontario are particularly prone to waterspouts, as their warm waters during the summer and fall provide the perfect conditions for their formation.
Lake Huron and Georgian Bay: These regions also experience a significant number of waterspouts each season, particularly when cold fronts move over the warmer lake waters.
St. Lawrence River and Gulf: The expansive surface area and distinctive weather patterns in this region make it another frequent hotspot for waterspout activity.
Other Lakes: Large inland lakes such as Lake Winnipeg and Lake of the Woods, along with smaller lakes that have the right conditions, can also see waterspouts develop.
If you're planning to be in these regions during the summer and fall, staying informed about weather conditions is an essential safety precaution.
How to Respond to a Waterspout
Encountering a waterspout can be a terrifying experience, but remaining calm and responding quickly can make all the difference between a narrow escape and a disaster.
If You Spot a Waterspout While Boating
This is the most critical situation. Your top priorities are to distance yourself from the waterspout and seek shelter as quickly as possible.
Steer away immediately
Do not attempt to get closer for a better view or a photo. Head in the opposite direction, at a right angle to the waterspout's path. Avoid trying to outrun it by moving parallel to its course.
Put on a life jacket
Even if the weather appears calm, put on a life jacket as soon as you spot a waterspout. The strong winds from the waterspout can create intense turbulence, and there's a risk of being thrown from the boat.
Head for shore or a marina
If possible, head toward the nearest safe location. While waterspouts typically have a short lifespan, you don’t want to be on the water when it dissipates or changes direction.
If You're Camping or Sightseeing Near Shore
Although you might feel safer on land, a waterspout can still be dangerous, particularly if it's a tornadic waterspout or if it moves ashore.
Seek indoor shelter immediately
If you spot a waterspout, do not stay outside to watch it. Seek shelter in a permanent building or a sturdy structure immediately. If it takes time to reach indoor shelter, ensure you have reliable lighting and a way to stay connected. A portable power station, like the EcoFlow River 2 Pro, can keep your emergency lights and communication devices powered until you're safe.
Avoid flimsy structures
Tents, lean-tos, and even small sheds provide little to no protection against the powerful winds of a waterspout.
Stay away from windows
If you're inside a building, head to an interior room and avoid windows and doors for protection.
How to Prepare in Advance
Being prepared is your best defense against the unpredictable nature of waterspouts. A bit of planning can make a significant difference in an emergency.
Pay Attention to Weather Warnings
Before you head out, always check the weather forecast. Pay close attention to warnings from Environment and Climate Change Canada (ECCC) for:
Severe thunderstorm watches and warnings
Tornado watches and warnings
Special marine warnings
If you're on the water, consider using a weather radio to receive real-time updates and alerts.
Understand and Plan for Shelter
Familiarize yourself with your surroundings. If you're in a new area, take a moment to identify nearby shelters.
Boaters: Familiarize yourself with the closest marinas, bays, or coves where you can quickly seek shelter and secure your boat.
Campers/Sightseers: Locate the nearest solid structure, such as a park facility, restaurant, or visitor center, where you can seek shelter.
Prepare Portable Emergency Equipment
A bit of preparation such as preparing for power outages can make all the difference in an emergency. Having the right gear on hand could turn a close call into a safe escape. Here’s a closer look at the essential items you should always keep with you.
Life Jackets (Personal Flotation Devices)
Make it a habit for everyone on the boat to wear a properly fitting life jacket (or PFD). The powerful winds of a waterspout can throw you overboard in an instant, and it’s far too late to find one once an emergency strikes.
In a waterspout emergency, losing power can cut off access to essential tools like weather updates, GPS, or communication with rescue teams. That’s why having a reliable portable power source on hand before you head out is crucial.
For example, the EcoFlow River 2 Pro and EcoFlow Delta 2 portable power stations are exceptional tools for ensuring reliable power in unpredictable situations. These devices offer long-lasting, dependable power in a compact, easy-to-carry design. On a boat, they can keep your marine radio, GPS, and emergency lights running for hours, helping you navigate and stay connected during a waterspout emergency. On land, they can charge smartphones and other essential devices, even when the grid goes down. Thanks to their fast recharging capabilities and multiple output ports, the EcoFlow River 2 Pro and EcoFlow Delta 2 ensure you stay informed, safe, and connected—no matter how unpredictable the weather becomes. Their efficiency and versatility make them an indispensable addition to your emergency preparedness gear.
Emergency lights
During a waterspout, heavy clouds and rain can drastically reduce visibility. A reliable light source becomes essential to help you navigate through the chaos. A headlamp allows you to keep your hands free for other tasks, while a portable lantern or flashlight can provide crucial illumination to help you assess your surroundings.
Communication devices
Always ensure your phone is fully charged before heading out. If you're boating far from shore, a marine radio is a must-have. Unlike cell phones, marine radios often work in areas without cell service and are continuously monitored by the Coast Guard and other vessels, offering a more reliable means of calling for help in an emergency.
