Because freezing rain does not hit the ground as an ice pellet (called “sleet”) but still as a rain droplet, it conforms to the shape of the ground, or object such as a tree branch or car. This makes one thick layer of ice, often called “glaze”. Freezing rain and glaze ice on a large scale is called an ice storm.

Ice pellets are a form of precipitation. Ice storms occur when precipitation particles melt and then fall through a layer of cold air near the ground. Sleet results when the layer of subfreezing air at the surface extends upward far enough so that raindrop freezes into a little ball of ice.

Freezing rain develops when warm oceanic air rises up and over the cold air, producing liquid precipitation that falls through the cold layer. The falling droplets become supercooled and freeze on impact with the cold surface.

Ice pellets form when snowflakes start to melt as they fall from the cloud, then fall through sub-freezing air where they re-freeze into grain-like particles. Sometimes the snow may only partially melt and fall as snow pellets encased in a thin layer of solid ice.

Sleet (a.k.a. ice pellets) are small, translucent balls of ice, and smaller than hail.

A thicker wedge of cold air beneath the warm air refreezes the partially melted snow into ice pellets. For freezing rain to occur, the warm air layer is thicker. The snow melts into rain then refreezes just as it hits the cold ground. Sleet is made up of ice pellets that bounce off objects.

Go slow and avoid heavy braking, which could cause you to skid and lose control of your vehicle. Make sure to leave extra time to get where you’re going so you can drive at a safe speed without feeling stressed. Keep a safe distance. We all know this rule, but don’t always practice it.

That rain is followed by a fast moving cold front in the evening that drops temperatures 15° in just a few hours. That means wet roads will quickly freeze over as air temperatures hover in the middle 20s.

Is it dangerous to drive in freezing rain? Unlike snow, which is highly visible to the eye, freezing rain can be undetectable and dangerous. Because these conditions are less visible, they can actually be more dangerous to drive in than more visible conditions such as snow.

Half an inch of ice can add as much as 500 pounds to a power line, and damage can begin when accumulations exceed a quarter of an inch.

According to most meteorologists, just one quarter of an inch of ice accumulation can add about 500 pounds (230 kg) of weight per line span. Damage from ice storms is easily capable of shutting down entire metropolitan areas.

Ice rolling involves attaching a roller to the end of a long pole or rope which is then hung onto a conductor. We pull the roller along the power line, cracking the ice off as it goes. This is a manual procedure often done in freezing rain and storm conditions. Rolling is done when melting is not an option.

I don’t see any reason to knock ice off a utility wire. Whether power line, phone line or, cable line, they are all reinforced and designed to hold up to ice and wind loads. When power lines break during ice storms it is almost always due to a tree branch loaded with ice/snow that breaks off and falls on the wire.

Wet snow can cause significant damage to lines even when accompanied by strong winds.

During winter, ice build-up on the power lines makes them too heavy to be carried by poles or towers increasing their chances of failure. Apart from temperature and ice build-up, sagging is also affected by wind. Wind is known to cool down cables, thus allowing them to transmit more power than they normally do.

Temperature affects how electricity flows through an electrical circuit by changing the speed at which the electrons travel. This is due to an increase in resistance of the circuit that results from an increase in temperature. Likewise, resistance is decreased with decreasing temperatures.

The short answer is yes, cold weather can be the reason for a power outage. One reason is because on cold days the electric heaters are turned up throughout the electrical system which can cause an equipment overload.

It takes a lot more energy, or heat, to get protons moving. As their motion becomes more random, these protons are more likely to get in the way of the electrons. That disrupts the current flow. As a result, the higher the temperature, the higher the resistance to the flow of electrons — and electricity.

Overheating is a phenomenon of rising temperatures in an electrical circuit. Overheating causes damage to the circuit components and can cause fire, explosion, and injury. Damage caused by overheating is usually irreversible; the only way to repair it is to replace some components.

Called “standby” electricity loss because it’s so often associated with electronics in standby or idle mode, it’s also known as “phantom” or “vampire” electricity (for obvious reasons). Even turned off, many appliances keep drawing power. Same goes for all those chargers — whether or not a device is charging!

Due to the wires having electrical resistance, which means that they resist the motion of electrons, the electrons bump into atoms on the outside of the wire, and some of their kinetic energy is given to the atoms as thermal energy. This thermal energy causes the wire to heat up.
