Freezing Rain: GTA and Vicinity Alert

Freezing rain is a dangerous weather phenomenon that can quickly transform the Greater Toronto Area (GTA) and surrounding regions into a treacherous landscape. This article will explain what freezing rain is, the risks it presents, and what you should do to stay safe during a freezing rain alert.

Understanding Freezing Rain

Freezing rain occurs when rain falls as liquid water through a layer of above-freezing air and then freezes upon contact with surfaces that are below freezing (0°C or 32°F). This creates a coating of ice, often referred to as glaze, on roads, trees, power lines, and other surfaces. Unlike snow or sleet, freezing rain is transparent and can be difficult to detect until it's already accumulated a significant layer.

How Freezing Rain Forms

The formation of freezing rain requires a specific atmospheric condition: a layer of warm air above a layer of cold air near the ground. Rain falling through the warm layer remains liquid. However, as it reaches the colder layer near the surface, the temperature drops below freezing, causing it to instantly freeze on contact.

Risks Associated with Freezing Rain

Freezing rain poses several significant risks:

• Hazardous Driving Conditions: Glaze on roads makes driving extremely dangerous, significantly increasing the risk of accidents and collisions. Even small amounts of ice can make roads incredibly slippery.

• Power Outages: The weight of ice accumulating on power lines can cause them to snap, resulting in widespread power outages that can last for hours or even days.

• Tree Damage: The weight of the ice can also cause trees and branches to break, potentially damaging property and posing a risk to people and vehicles.

• Travel Disruptions: Freezing rain can lead to significant disruptions to travel, including delays and cancellations of flights, trains, and buses.

• Injuries: Falls on icy surfaces are a common occurrence during freezing rain events, leading to injuries ranging from minor bruises to serious fractures.

Staying Safe During a Freezing Rain Alert

Preparing for freezing rain is crucial to minimizing risks. Here are some important steps you should take:

Before the Storm:

• Monitor Weather Forecasts: Pay close attention to weather warnings and advisories issued by Environment Canada.
• Prepare an Emergency Kit: Gather essential supplies such as flashlights, batteries, blankets, first-aid kit, bottled water, and non-perishable food.
• Charge Electronic Devices: Ensure your cell phone and other electronic devices are fully charged.
• Clear Your Property: Remove any loose branches or debris that could fall and cause damage.

During the Storm:

• Stay Indoors: Avoid unnecessary travel during a freezing rain event. If you must go out, exercise extreme caution.
• Drive Carefully (if necessary): If you must drive, reduce your speed, increase your following distance, and avoid sudden braking or acceleration.
• Check on Vulnerable Neighbors: Check on elderly neighbours or those who may need assistance.
• Report Power Outages: Contact your electricity provider to report any power outages.

After the Storm:

• Clear Ice Carefully: Be cautious when removing ice from your property. Use appropriate tools and avoid overexertion.
• Inspect Your Property for Damage: Check for damage to trees, power lines, and your home.

Freezing rain is a serious weather event. By understanding the risks and taking appropriate precautions, you can significantly reduce your risk of injury and property damage. Stay informed, stay prepared, and stay safe.
