Tropical Storm Warning for The Gulf Coast from Morgan City, Louisiana, to Sargent, Texas

Meaning of the warning

A Tropical Storm Warning means that tropical storm conditions are expected somewhere within the warning area, in this case within 24 hours.

Hazards affecting land

Wind. Tropical storm conditions will continue spreading across portions of the Louisiana and Texas coasts within the warning area into the evening.

Storm surge. The combination of storm surge and the tide will cause normally dry areas near the immediate 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…

Port Bolivar, TX to Port Fourchon, LA…1-2 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.

Rainfall. Bertha is expected to produce total rainfall amounts of 2 to 4 inches with isolated totals to 6 inches through Thursday night along Texas Gulf Coast and South Texas. This rainfall may produce isolated flash flooding, especially in urban areas.
