A storm surge watch has been issued for the northern Gulf of Mexico coast from Indian Pass to Arepika, Florida, and from Grand Isle, Louisiana, to Ocean Springs, Mississippi, including Lake Borgne.

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:

At 10 a.m. CDT, the center of Tropical Depression Cristobal is located about 40 miles (65 km) east of Campeche, Mexico. It’s moving toward the north near 12 mph (19 km/h). On the forecast track, the center will move back over the southern Gulf of Mexico this evening, over the central Gulf of Mexico on Saturday, and be near the northern Gulf of Mexico coast Sunday evening.

Maximum sustained winds are near 35 mph (55 km/h) with higher gusts. Some strengthening is forecast to occur during the next 48 hours, and Cristobal is expected to regain tropical storm strength later today. Some additional strengthening is forecast thereafter.

Isolated significant river flooding is possible along the central Gulf Coast.

Rises along smaller-order streams are possible across the Mid-Mississippi Valley. This degree of rainfall is expected to lead to flash flooding.
