WIND: Tropical storm conditions are expected to reach the coast within the warning area by Tuesday morning, making outside preparations difficult or dangerous. STORM SURGE: The combination of storm surge and tide will cause normally dry areas near the coast to be flooded by rising waters moving inland from the shoreline. 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. For a complete depiction of areas at risk of storm surge inundation, please see the National Weather Service Peak Storm Surge Graphic, available at hurricanes.gov/graphics_at5.shtml?peakSurge. RAINFALL: Tropical Depression Five is expected to produce rainfall totals of 3 to 6 inches with maximum totals of 9 inches for parts of the Upper Texas Coast inland through east-central Texas, with potential for 2 to 3 inches in far Southwest Louisiana. This rainfall is likely to produce flash flooding, especially in low-lying and urban areas. River flooding may also be possible.
