Freezing rain forms as snow, melts as it passes through a warmer layer of air and then becomes a super-cooled liquid, which freezes on impact. Freezing rain normally forms on the leading edge of a warm front overtaking a... More »

When one speaks of weather, the term freezing equates to the freezing point of water, 32 degrees Fahrenheit or zero degrees Celsius. It is at this point that precipitation is likely to fall as snow, sleet or freezing rai... More » Science Weather & Tides

Meteorologists classify freezing fog as a type of fog containing very cold water particles; these particles remain in a liquid state as low as 14 degrees Fahrenheit in the air, but turn to ice upon contacting colder surf... More » Science Weather & Tides Clouds

Sleet forms when snows travels through a layer of warm air, melting into raindrops, before re-freezing into tiny ice pellets upon hitting a colder layer of air. More »

A mudflow is the downhill movement of soft, wet earth and debris made fluid by rain or melted snow. Mudflows occur when water mixes with soil and rock. They are most common in mountainous regions when a long dry season i... More » Science Weather & Tides Storms

Winter storms develop when low pressure systems come into contact with a cold front or a warm front, which causes low temperature precipitation such as snow and freezing rain. Common types of winter storms caused by low ... More »

An ice storm is a dangerous weather event that occurs when snow melts in a warm layer in the atmosphere before freezing as it reaches the ground. Ice storms cause build-up of ice on roads, buildings, cars and trees. Driv... More » Science Weather & Tides Storms
