Pouring Precipitation

Rain, Hail, Snow, and Sleet

All the Types!

There are four major types of precipitation

•hail

•snow

•rain

•sleet

These can change your daily activities and cause big problems like damage to house and even death.

Rushing Rain

Rain is one of the most common types of precipitation in most places. If the temperature is above 32°F it will most likely fall as rain instead of sleet, snow, or hail. Rain can be very hard and cause flooding. (look to dangerous precipitation) It also is part of storms like hurricanes and thunder storms. (look to precipitation in storms) With the ice it can create (look to freezing and icy rain) rain can be very dangerous and cancel activities.

Water Cycle

If you click the link below you can watch a video about the water cycler which is the never ending cycle of water leaving Earth and returning to it. There are three major stages of the water cycle. Evaporation, condensation, and precipitation.

How it forms

Water droplets form from condensation. After the cloud forms many tiny water droplets are inside. As they form they become heavier and begin to fall. If they are in larger clouds there will be bigger raindrops. If it is a smaller cloud the rain drops will be smaller since they had less time to form.

Soft snow

Do you want to build a snowman? Well to build a snowman you need some snow. Snow can only fall at around 32°F and under. Snow can pile up very high and cause car accidents and cancel activities or school. It is a big part of blizzards too. (look to precipitation in storms)

How it Forms

There are different types of snow. The first one is "wet snow". That type is formed at warmer temperatures with more water vapor. The snow sticks together and is larger. There is also "powder". This type of snow forms at cooler temperatures and is great for skiing. Watch out for your next snow storm!

Sleet and Hail

Slippery Sleet

Sleet is common in temperatures around 35°F to about 39°F. It forms when rail falls through a thick layer of very cold air and freezes just before it hits the ground. It can cause slippery roads which can lead to car accidents and delays or no school.

Heavy Hail

Hail forms in violent thunderstorms. They start in clouds a small clusters of ice. As they fall through supercooled cloud droplets they form "onion" like layers of ice. Hail can get as big as a softball! They can be very dangerous and give you injuries. (look to dangerous precipitation) Watch out!

How precipitation can effect you

Dangerous Precipitation

Precipitation can be very dangerous. Rain can cause flooding which is very bad. People can have their houses destroyed. Snow is a big part of blizzards and blizzards can leave you stuck in your house with no power or heat which is not fun. Hail can destroy cars and houses. Sleet can create slippery roads and you can slip off the road and die.

Precipitation in storms

Many storms include precipitation. One of these storms is a blizzard. These include heavy snow and high wind speeds. Hurricanes usually bring lots of rain and very high winds. Tornadoes often start as violent thunder storms which can bring hail. Also thunder storms may include rain and hail. Sleet sometimes can be a part of blizzards.

Freezing and Icy Rain

When temperatures start above 32° then become below 32° you may be left with icy rain or sleet. This icy rain can cause many accidents and dangerous roads. Also if rain is left on the road from a rainy day and the temperature drops to below 32° it can create ice or black ice. With roads being icy schools can be delayed or even cancelled.
