Freezing Rain Followed by Rain: A Dangerous Combination

Freezing rain followed by rain is a weather phenomenon that poses significant risks. Understanding the differences and dangers of this sequence is crucial for staying safe. This post will delve into the science behind this hazardous weather event, the dangers it presents, and what precautions you should take.

Understanding the Science Behind Freezing Rain and Rain

Freezing rain occurs when rain falls through a layer of sub-freezing air near the ground. This causes the raindrops to supercool, remaining liquid even though their temperature is below 0°C (32°F). Upon contact with surfaces like roads, trees, and power lines, these supercooled droplets instantly freeze, forming a coating of ice. This is different from snow, which forms directly from ice crystals in the atmosphere.

Rain, on the other hand, is simply water that has condensed in the atmosphere and falls to the ground as liquid. The transition from freezing rain to rain typically happens as the temperature above freezing rises, melting the ice crystals before they reach the ground.

The Dangers of Freezing Rain Transitioning to Rain

The sequence of freezing rain followed by rain is particularly dangerous because:

• Initial Ice Accumulation: The initial freezing rain creates a layer of treacherous ice on all surfaces. This glaze of ice makes roads extremely slippery, increasing the risk of car accidents. Power lines become heavy and prone to breaking, leading to power outages.
• Weight of the Rain: The subsequent rain, while not freezing, adds weight to the already ice-covered surfaces. This added weight can further stress power lines and trees, increasing the likelihood of damage. The weight also makes walking on icy surfaces even more hazardous.
• Hidden Ice: The melting ice can create hidden patches of ice, making it difficult to discern safe areas for walking or driving. These hidden hazards are particularly dangerous as they are not readily visible.
• Flooding: If the rain is heavy enough, it can lead to localized flooding, further compounding the hazards posed by the initial ice.

Staying Safe During Freezing Rain and Rain

When freezing rain is forecast, or already occurring, it’s crucial to take precautions:

• Stay Indoors: Avoid all unnecessary travel during freezing rain and the transition to rain. The risk of accidents is significantly increased.
• Prepare Your Home: Have an emergency kit ready, including flashlights, batteries, warm blankets, and non-perishable food and water.
• Check on Vulnerable Neighbors: Check on elderly neighbors or those with disabilities to ensure they are safe and have access to necessary resources.
• Driving Precautions: If you must drive, proceed with extreme caution. Drive slowly, increase your following distance, and ensure your tires have good tread. Consider carrying tire chains.
• Power Outages: Be prepared for potential power outages. Know how to safely operate any backup generators.

Protecting Your Property

• Trees and Branches: Be aware of the potential for falling tree branches, especially large, heavy branches weighed down by ice and rain. Try to clear away any potentially hazardous branches before the storm hits.
• Gutters and Downspouts: Ensure your gutters and downspouts are clear of debris to prevent ice dams and water damage.

Monitoring Weather Forecasts

Staying informed about weather forecasts is critical. Pay close attention to weather alerts and warnings issued by your local meteorological service. Understanding the difference between freezing rain and rain, and the potential dangers of this combined event, is paramount for staying safe. Be prepared, and stay informed. Your safety is your responsibility.
