A mix of rain and melted snow is commonly known as sleet. This form of precipitation occurs when raindrops pass through a layer of cold air, partially freezing before hitting the ground. Sleet can create slippery and hazardous conditions on roads and walkways, so it’s essential to exercise caution during such weather events.
