September - rain You are here: Home Photo gallery Clouds Severe weather Updraft cumulus


At well-organized storms, the updraft is usually visible at the flank of the storm, where the flanking line connects to the storm tower. If the storm is severe, one can usually visually see the updraft cumulus grow towards the anvil of the storm explosively. Updraft towers are sometimes accompanied by clear hail fallstreaks. Generally, the stronger the updraft, the larger the hail which will fall out of it. Next to the updraft is usually a downdraft (rainfall).
