Where is Hurricane Isaias now?

At 10 a.m. CDT on Thursday, the center was near 23.7°N, 90.2°W, about 380 miles south of the mouth of the Mississippi River. The storm was moving east-northeast at 10 mph with maximum sustained winds of 85 mph. The NHC forecast landfall somewhere within the northern Gulf Coast warning area late Friday or early Saturday. A precise landfall point was not certain.

Storm surge and hurricane warnings

A storm surge warning extended from the mouth of the Mississippi River to the Suwannee River, Florida. A hurricane warning covered Ocean Springs, Mississippi, to the Bay/Gulf County line in Florida. The NHC forecast potential peak surge of 5–7 feet in some areas between Ocean Springs and Indian Pass, including Mobile Bay, if peak surge coincided with high tide. Local conditions will vary.

Rainfall, flooding and tornado risks

Forecast rainfall of 3–7 inches was possible across the central Gulf Coast, with localized totals as high as 15 inches, especially in parts of the Florida Panhandle and Big Bend. Flash flooding, river flooding and isolated tornadoes were also possible. Residents should not drive through flooded roads and should follow evacuation instructions from local officials.

What happens next?

The NHC expected further strengthening into early Friday. Coastal residents should prepare for possible power interruptions and transportation disruption. The forecast is not a guarantee that every warned location will experience the same conditions.
