By Madison B. It has to be a general tiny size to fall. Sleet is made with frozen rain. There can be a area of a big area of sleet. Unlike snow and raindrops pass a liquid from before freezing rain. The requite are not light or fluffy. If your in sleet stay inside and stay safe. It stares as snow and then it melts into frozen rain. Then it goes into sleet. Warning ice storms can be caused by freezing rain. It goes for eight houl hours.
