After Gabriel, two tropical waves could spell out the trouble
Hurricane Gabriel is set to steadily lose its tropical status on its way across the Atlantic, but what will happen next in the tropical?
This week, complex weather dances are underway in the Central Atlantic, as the developing tropical systems are trying to put together their actions.
“There are two tropical waves moving through the Atlantic that could develop this week,” Accuweather hurricane expert Alex Dasilva said in an email to USA Today.
Since neither is a designated storm, the two systems have been called “Invest 93L” and “Invest94L” by the National Hurricane Centre.
The peak of the 2025 Atlantic hurricane season may have arrived later than historic average, but activity is clearly on the rise, predictors warned on September 23.
The developing system is in the background of what has been a quiet season so far, and there have been no hurricane landings this year. Gabriel, the second hurricane of the season, continues to scream towards the sea on his way to Europe.
The Atlantic System on the Move
“The two waves we’ve been tracking are now tagged as Invest 93L (the Eastern wave that looks a little more robust) and Invest 94L (the West). There’s still a lot of uncertainty about how these systems interact.”
“The 93L is quite likely to become a repeat hurricane similar to Gabriel. The 94L could take a more west coast truck and pose a threat to the east coast, but it’s not clear how strong it will become due to its interaction with the island,” Hazelton said. “And of course, these waves are close enough that we can see the direct and/or indirect interactions between them. Complex predictions!”
Atlantic hurricane predictions include “complete confusion”
The upper air pattern in the southwest Atlantic is “complete disruption,” meaning that uncertainty will increase dramatically, says Houston-based meteorologist Matt Lanza, who said he was “The Eyewall” in his subsack “The Eyewall” on September 23rd.
“The whole pattern is monitoring the East Coast for next week or so,” he said. “But the uncertainty is very high, and a lot is happening in small areas, and one feature is affecting the other areas.”
“People on the East Coast from Florida to New England will need to monitor the progress of these systems in the coming days to see if they can pull out signals from this, because they can’t now.”
Hurricane Gabriel ends the scene
“Hurricane Gabriel remains impressive as a Category 4 storm in the Mid-Atlantic Ocean,” said weather trader meteorologist Ryan Maue in the Materials Post on September 23.
The Hurricane Centre said the hurricane watch was wound up by Azores weather services. “Clocks are usually issued 48 hours before the expected first outbreak of tropical storm-force winds, a condition that makes external preparation difficult or dangerous,” the Hurricane Center said.
“Gabriel was able to bring a ferocious situation to the Azores from late Thursday until early Friday, but it’s too early to know if it’s going north of the Portuguese Islands or soon,” WPLG-TV Hurricane Specialist Michael Lowry said in the Subsack Post. “For now, the model suggests a more direct threat to less populated northern islands like Flores and Corvo.”
“It’s still a little too early to say how it will affect Europe, but the low approach left by early next week could be approaching Portugal.”
US influence from Gabriel
The US influence from Gabriel includes rough waves on the East Coast and dangerous swimming conditions.
“The swell created by Gabriel will continue to affect Bermuda, the US East Coast and Atlantic Canada for the next few days,” the National Hurricane Centre said. “These swells are expected to create life-threatening surfing and tear current conditions.”
The National Weather Service in Melbourne, Florida warned that “the risk of a flow of life-threatening clefts on the beaches as they swell from the major parts of faraway Hurricane Gabriel. No advice has been given to entering the waves.”
