WIND: Tropical storm conditions are expected to reach the coast within the warning area by Tuesday morning, making outside preparations difficult or dangerous.

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... High Island, TX to Vermilion/Cameron Parish Line, LA...2-4 ft Vermilion/Cameron Parish Line, LA to Morgan City, LA...1-3 ft The deepest water will occur along the immediate coast near and to the right of the center. Surge-related flooding depends on the relative timing of the surge and the tidal cycle, and can vary greatly over short distances. For information specific to your area, please see products issued by your local National Weather Service forecast office.
