Pittsburgs greatest danger during the hour of the shift will be the river coursing through the town. A strong and well established drainage in an area not subject to mountain building will find itself utilized aggressively to drain the deluges that will fall during the shift. Hurricane force winds, passing over ocean water, will pick up water tonnage and drop this suddenly in horrendous downpours when updrafts along mountain ranges occur. Those who have not witnessed rampaging water, moving with great force when under pressure from water upriver creating water pressure that seeks a release, will be shocked to watch the speed and height that such raging water can attain. Those along the headwaters of the Ohio, where it passes through ravines in well established drainage conduits, will be advised to stay well away from and above this anticipated flood.
