A less severe rating of 2 denotes hazardous driving conditions. Residents are discouraged from traveling unless it is unavoidable. Those choosing to travel are advised to call ahead to their destination, and contact their place of work to confirm that they are open for business before departing from home. Level 1 is the least dangerous warning, but drivers are still warned that roadways will be hazardous and that they must use extreme caution when traveling.
These different ratings initially caused confusion in the state due to misunderstandings. However, making warning levels clearly defined has made reporting dangerous conditions less subjective and much more streamlined. Rather than declaring this or that road closed, authorities can simply update the emergency rating with local news outlets and law enforcement in order to communicate the current threat level to drivers. Even with this warning system in place, it will likely take a severe winter before the majority of the motoring public fully understands the system and what each emergency level really means.Learn more about Snow
Snow, which is made up of millions of ice crystals and air pockets, reflects all of the wavelengths of light in the visible spectrum. When combined, the reflected light wavelengths create a white color. All objects in the world get their color based on which wavelengths of light they absorb and which ones they reflect.Full Answer >

Snow is cold because it is formed by water crystals combining, a process that can only occur when the temperature falls to 35 degrees Fahrenheit or below. When the temperature is over 35 degrees Fahrenheit, the precipitation is made of sleet or rain.Full Answer >
Snowflakes form in the atmosphere when extremely cold water droplets form frozen crystals around tiny particles of dust or pollen. When these ice crystals fall closer to the ground, water vapor freezes onto the primary crystal and snowflakes grow larger with more crystals. This frozen water creates six-sided crystals.Full Answer >
