Atlantic Hurricane Season 2026: Tropical Storm Isaias Could Become the First Hurricane

Atlantic hurricane season 2026 has been unusually quiet, but conditions could change this week. Tropical Storm Isaias is expected to strengthen into the season’s first hurricane and make landfall somewhere between Mississippi and Florida by the end of the week.

Isaias Could Strengthen Into a Category 2 Hurricane

El Niño turned the Atlantic Basin into a graveyard by changing wind patterns and tearing storms apart high in the atmosphere. As a result, tropical cyclone activity has fallen to near-record lows, and the number of hurricanes has remained at zero. However, that could change quickly.

Isaias is moving through the Gulf of Mexico with winds of 105 mph, according to the latest information from the U.S. National Hurricane Center. That intensity is just below hurricane strength. The storm is expected to pass over unusually warm water, which could provide additional fuel for strengthening.

Isaias could become a Category 2 storm with winds of up to 110 mph as it turns northeast. The storm is then expected to weaken before making landfall somewhere along the Gulf Coast, although severe winds could still pose a serious threat.

Hurricane Watches Issued Along the Gulf Coast

The NHC has issued hurricane watches for the entire coastlines of Mississippi and Alabama, as well as parts of the Florida Panhandle. Tropical storm watches also extend to Louisiana.

People in the affected areas could receive up to 7 inches of rain. Some locations in the Florida Panhandle could see as much as 10 inches. Storm surge may reach 7 feet, and tornadoes are also possible. Residents should take the storm seriously and follow guidance from local officials.

Could Isaias Set a Record for the Latest First Hurricane?

Isaias could also make history as the latest first Atlantic hurricane on record. The current record was set in 1905, when the season’s first hurricane occurred on October 8. Isaias still has one more update scheduled for Wednesday, so it could miss the opportunity to match that record.

Why the 2026 Atlantic Hurricane Season Has Been So Quiet

Regardless of whether it sets a record, Isaias demonstrates how quickly conditions can change during hurricane season. This year’s Atlantic hurricane season was expected to be below normal, but activity has been even quieter than anticipated because of El Niño.

This El Niño event has been described using terms including “super,” “Godzilla,” and “supersized.” Meteorologists note that these are informal superlatives rather than official designations. El Niño is measured by ocean temperatures in parts of the tropical Pacific, and this year’s event reached record highs throughout the summer and early fall.

The intensity of El Niño is affecting atmospheric patterns around the world, including over the Atlantic Ocean. Sahara dust is also helping suppress storm development by making the air extremely dry in one of the main hurricane-prone regions.
