These graphics depict a simulation of the direction and speed of potential ash cloud motion from Cleveland. IF a significant ash cloud were generated
by the current eruption. It does not mean that such an ash cloud has been produced. These models are run every 6 hours independent of the current eruptive
state of the volcano. Each colored line indicates the direction a cloud would travel at different altitudes (see key below map plot).
