The Gulf Coast Could Face a Serious Hurricane Early Next Week

The exact track is still coming into focus, but nowhere in the Gulf Coast should sleep on the storm that's forecast to become Hurricane Ida.

We’re heading into the peak of Atlantic hurricane season with a storm on the horizon. And unfortunately, it could be a very serious one.

Tropical Storm Henri brought plenty of rain to the Northeast and parts of the Caribbean last week, but what’s forecast to become Hurricane Ida could be on another level. Tropical Storm Ida is currently in the Caribbean, and will plow through Cuba and the Cayman Islands in the next 24 hours before hitting the warm waters of the Gulf of Mexico. Once there, everything is lining up for it to become a beastly hurricane as it moves northwest. Ida will be poised to wreak havoc somewhere on the Gulf Coast on Monday, almost a year to the day after Hurricane Laura hit western Louisiana and 16 years after Katrina struck New Orleans.

If you live in the region, absolutely start paying attention to the forecast. The track will likely change in the coming days as soon-to-be Ida moves closer, but the risk of a life-threatening storm is very real.


Where Things Stand Now

Ida was a tropical depression for much of Thursday before being upgraded to a tropical storm after Hurricane Hunter aircraft found wind speeds of 40 mph (64 kph). That was to be expected, and the National Hurricane Center had already issued tropical storm warnings for the Caymans and Cuba in anticipation of what will be Tropical Storm Ida reaching those countries in the next 36 hours. The Caymans will likely feel tropical-storm-force winds by this evening.

This is already a pretty big system; while Jamaica isn’t forecast to be hit by the storm head-on, it is expected to be drenched by Ida as bands of rain wrap around the strengthening system. The NHC is calling for up to 15 inches (38 centimeters) of rain on the island, located 230 miles (370 kilometers) east of the Caymans. Cuba and the Cayman Islands themselves will see widespread rainfall totals of 6 to 10 inches (15 to 25 centimeters) of rain, with some areas getting 20 inches (50 centimeters). That could mean floods and landslides across each of those nations.

The NHC also warned of up to 4 feet (1.2 meters) of storm surge that would be accompanied by “large and destructive waves.” In short, while Ida will “only” be a tropical storm, it has the potential to do major damage in the region.


What Happens Once Ida Reaches the Gulf of Mexico

Ah, the million-dollar question. Once Ida clears Cuba’s western tip, the storm will be in the Gulf of Mexico. Waters there are plenty warm to help Ida become a hurricane.

Outside an area churned up by Hurricane Grace off the Yucatán Peninsula last week, most of the Gulf is abnormally warm. And the waters where Ida is forecast to go are particularly toasty, running up to 3.6 degrees Fahrenheit (2 degrees Celsius) above normal for this time of year. Critically, those waters are 86 degrees Fahrenheit (30 degrees Celsius) or hotter, a threshold that tends to help storms rapidly intensify. Your regular reminder that hotter than normal waters is also a hallmark of climate change.


By Sunday morning, the NHC forecast indicates that Ida could be a shade below a Category 3 hurricane, what’s considered a major ‘cane. So far, there’s only been one major hurricane in the basin this year. Hurricane Grace attained Category 3 status over the Bay of Campeche between the Yucatán and the Mexican state of Veracruz. We’ll see how Ida develops, but it could be this year’s second major hurricane if conditions stay favorable.

Right now, the forecast track puts it somewhere off the coast between Louisiana and Texas. That is particularly worrisome given that the region was walloped by Hurricanes Laura and Delta last year, as well as the deep freeze that hit the South this winter.


It’s too early to be talking about exact landfall or impacts in the U.S., and the track will likely shift. That said, everything indicates this is not a storm to be trifled with. Major storm surge, rain, and wind are all in the cards. If you live along the Gulf Coast, this is basically the “ready” phase of “ready, set, go” in terms of preparation. That means it’s worth watching the track closely over the next few days, and as the track becomes clearer, perhaps shifting into “set” mode.

The Peak of Hurricane Season Is Nearly Here

The map of the tropics is starting to look a little busier. In addition to the storm in the Caribbean, the NHC is also tracking two other areas of interest in the Atlantic. The agency has been expecting an above-average season in terms of activity, and the statistical peak is in mid-September so things are ramping up right on time. Unfortunately.


The agency also upped what an “average” season is this year after a decade of new data showed we’re seeing more storms form in the Atlantic. That’s due to climate change as well as better observations. So cluttered maps like the one currently on the NHC site—and last year’s record-setting season from hell—are precursors of the future.
