Update: Hurricane, Storm Surge Watches Issued for Florida Panhandle Ahead of Isaias

Update: The National Hurricane Center issued the first U.S. coastal watches for Tropical Storm Isaias at 10 a.m. CDT (11 a.m. EDT) on Wednesday, October 7, 2026. A Hurricane Watch now covers the coast from Bay St. Louis, Mississippi, to Indian Pass, Florida, and a Storm Surge Watch runs from the mouth of the Mississippi River to Yankeetown, Florida. Forecasters expect Isaias to become a hurricane by Thursday and approach the northern Gulf Coast on Friday. This is a developing story.

This post updates our earlier report from this morning, Tropical Storm Isaias Forms in Gulf; Hurricane Forecast for Northern Gulf Coast, which was written before any watches were in effect.

What Is New

Advisory Number 4 put three watches in place along the northern Gulf Coast (National Hurricane Center):

• Hurricane Watch: Bay St. Louis, Mississippi, to Indian Pass, Florida. This includes the Mississippi and Alabama coasts and the western and central Florida Panhandle.
• Storm Surge Watch: Mouth of the Mississippi River to Yankeetown, Florida. This covers the Panhandle and the Big Bend coast of Florida.
• Tropical Storm Watch: From the Jefferson and Plaquemines Parish line in Louisiana to west of Bay St. Louis, and from east of Indian Pass to the Aucilla River in Florida.

The advisory also gave the first storm surge height forecasts for the United States. If peak surge arrives at high tide, water could reach these heights above ground (National Hurricane Center):

• Ocean Springs, Mississippi, to Indian Pass, Florida, including Mobile Bay: 5 to 7 feet
• Mouth of the Mississippi River to Ocean Springs, Mississippi: 3 to 5 feet
• Indian Pass to the Aucilla River, Florida: 3 to 5 feet
• Aucilla River to Yankeetown, Florida: 2 to 4 feet
• Lake Pontchartrain: 1 to 3 feet

What Is Confirmed

At 10 a.m. CDT the center of Isaias was near 22.4 North, 93.6 West, about 260 miles west-northwest of Progreso, Mexico, and about 540 miles south-southwest of the mouth of the Mississippi River. Maximum sustained winds had increased to 45 mph, up from 40 mph early this morning, and the central pressure had fallen to 1000 millibars. The storm was moving east-northeast at 8 mph, and tropical-storm-force winds extended up to 45 miles from the center (National Hurricane Center).

Air Force Hurricane Hunter data showed the center re-forming closer to the mid-level circulation, and forecasters said that change could make rapid strengthening easier given light to moderate wind shear and near-record sea surface temperatures (National Hurricane Center forecast discussion).

The official forecast now calls for the following (National Hurricane Center forecast discussion):

• Thursday morning: hurricane strength, with 75 mph winds.
• Friday morning: a peak near 110 mph over the central Gulf.
• Friday evening: winds near 105 mph with the center near 29.2 North, 87.5 West, just off the coast.
• Saturday morning: inland and weakening, with winds near 50 mph.

Tropical storm conditions could begin in the watch areas around midday Friday, and hurricane conditions could begin in the Hurricane Watch area late Friday. Rainfall of 3 to 6 inches, with local totals up to 10 inches, is expected along the central Gulf Coast from Friday through the weekend, with 1 to 3 inches and local totals up to 5 inches across much of the Southeast (National Hurricane Center). In its key messages, the hurricane center told people in the Hurricane Watch area to "prepare for the possibility of long-duration power outages" (National Hurricane Center forecast discussion).

What Is Not Yet Known

The exact landfall point is still uncertain. The hurricane center said the model guidance remains split, with one group of models favoring the eastern side of the forecast envelope (National Hurricane Center forecast discussion). The storm is also expected to grow in size as it nears the coast, so impacts will reach well beyond the center.

No watches are in effect for the Tampa Bay area. The Storm Surge Watch ends at Yankeetown, on the coast north of Tampa Bay, and Orlando station WKMG reported that Central Florida is not expected to see direct impacts, although added tropical moisture could reach the region into the weekend (ClickOrlando). The same report notes that a hurricane on October 8 would tie the record, set in 1905, for the latest first hurricane of an Atlantic season. No watch has been upgraded to a warning yet, and this report does not cover local evacuation orders or emergency declarations, which are issued by state and county officials.

What It Means for Owners and Contractors

A watch means hurricane conditions or life-threatening surge are possible in the area, generally within 48 hours. For jobsites from coastal Mississippi to the Florida Big Bend, that turns general readiness into a schedule. With tropical storm conditions possible by midday Friday, the working window for outdoor preparation is the rest of Wednesday and Thursday.

• Use the surge numbers. Sites and laydown yards near the water between Ocean Springs and Indian Pass should plan around 5 to 7 feet of water above ground. Move equipment, fuel, electrical gear and moisture-sensitive materials to higher ground or upper floors.
• Finish crane and scaffold work early. Follow manufacturer and engineer requirements for tower cranes, mobile cranes, hoists and scaffolding before winds rise on Friday.
• Clear loose material. Secure or remove formwork, sheet goods, dumpsters, portable toilets and fence screening.
• Prepare for rain. Check dewatering, erosion controls and storm drains, and protect open excavations and unfinished roofing ahead of rainfall that could reach 10 inches in places.
• Plan for power loss. Owners of operating plants, cold storage and distribution buildings in the Hurricane Watch area should test generators, confirm fuel supply and review restart procedures.
• Document and notify. Photograph site conditions, and send any weather delay or force majeure notices your contracts require within the stated time limits.
• Put people first. Follow local evacuation orders, and release crews with enough time to secure their own homes and travel safely.

Projects in the Florida peninsula, including Tampa Bay, are outside the watch areas but should expect possible weekend rain and delays for deliveries that move through the Interstate 10 corridor and northern Gulf ports.

What to Watch

• The next full advisory at 4 p.m. CDT (5 p.m. EDT) Wednesday, with an intermediate advisory at 1 p.m. CDT (National Hurricane Center).
• Whether watches are upgraded to Hurricane and Storm Surge Warnings, which usually come about 36 hours before conditions arrive.
• Any shift of the forecast track east or west, which would change where the highest surge and strongest winds occur.
• Evacuation orders and emergency declarations from state and county officials.

Forecasts for this storm are changing with each advisory. Use the latest products from the National Hurricane Center and your local National Weather Service office for decisions, not this summary.
