The water could reach the following heights above ground somewhere in the indicated areas if the peak surge occurs at the time of high tide... Port Bolivar, TX to Mouth of the Mississippi River, LA...1-3 ft The deepest water will occur along the immediate coast. Surge-related flooding depends on the relative timing of the surge and the tidal cycle, and can vary greatly over short distances.
