Tropical Storm Isaias is strengthening in the Gulf of Mexico and is forecast to reach major hurricane strength before making landfall along the north-central Gulf Coast late Friday or early Saturday, according to the National Hurricane Center. Hurricane and storm surge watches are in effect from Mississippi to Florida.

As of Wednesday afternoon, Isaias had maximum sustained winds of 65 miles per hour and was located about 500 miles south-southwest of the mouth of the Mississippi River, moving east-northeast at 8 miles per hour. The storm's central pressure had fallen about 10 millibars since the morning, indicating strengthening.

NHC Director Michael Brennan said Isaias is expected to move northeastward to east-northeastward through Thursday while rapidly strengthening into a hurricane. It is forecast to turn north-northeastward on Friday and reach at or near major hurricane strength before coming ashore Friday night or early Saturday as a strong hurricane.

A hurricane watch extends from Bay St. Louis, Mississippi, to Indian Pass, Florida, including Mobile, Pensacola and Panama City. The watch also extends inland into parts of the Florida Panhandle and south-central Alabama. Tropical storm watches cover additional areas inland and on either side. Tropical storm conditions could begin along the affected coast Friday afternoon or evening, followed by hurricane conditions as the center comes ashore.

A storm surge watch stretches from the mouth of the Mississippi River to Yankeetown, Florida, covering the Mississippi and Alabama coasts, the Florida Panhandle and the Big Bend region. Water could rise 5 to 7 feet above ground level along portions of the Mississippi, Alabama and Florida coasts, including Mobile Bay, especially near and to the right of where the center makes landfall.

“The size of Isaias is expected to be quite large,” Brennan said, warning that dangerous storm surge could extend hundreds of miles east of the landfall location.

Rainfall could reach 10 inches near where the storm’s core comes ashore. A level three out of four risk for flash flooding is forecast from Friday into Saturday across an area including Mobile, Pensacola, Panama City and parts of south-central Georgia.

Isaias is expected to weaken into a tropical storm and then a tropical depression as it moves through the southeastern United States. Its moisture could bring scattered flash flooding across much of the region through the weekend. “You’ve got tonight and all day Thursday to get ready for the storm,” Brennan said.

Analysis

Why This Matters

  • Residents along the Mississippi, Alabama and Florida coasts face dangerous storm surge, hurricane-force winds and flash flooding from Friday onward.
  • Isaias is forecast to become a major hurricane, increasing the potential for property damage and prolonged power outages in affected areas.
  • The storm’s large size means impacts could extend hundreds of miles east of the landfall point, affecting communities far from the center.

Background

The Atlantic hurricane season runs from June 1 to November 30, with October historically active. Isaias formed as a tropical storm and is now expected to strengthen rapidly over warm Gulf waters. The National Hurricane Center issues watches and warnings to give coastal residents time to prepare.

Key Perspectives

Coastal residents: Those in the watch areas face decisions about evacuation, securing property and stocking supplies before conditions deteriorate Friday. Emergency managers: Local authorities in Mississippi, Alabama and Florida are monitoring the forecast and may issue evacuation orders as the storm approaches. The hurricane watch gives 48 hours of possible conditions. NHC forecasters: They stress the storm’s large size and potential for life-threatening storm surge, urging preparation by Thursday.

What to Watch

  • The storm’s exact track and whether it intensifies to Category 3 or higher before landfall.
  • Rainfall totals and flash flood risks, especially in already saturated areas.
  • Storm surge heights along the coast, which could be highest to the right of the landfall point.
