National Hurricane Center Monitoring Caribbean, Gulf
Posted on 09/19/2024
An area from the northwest Caribbean to the southern Gulf of Mexico is being watched closely for the possible formation of a tropical storm next week. It's too early for specific details, but the U.S. Gulf Coast should watch closely to see how this forecast evolves in the coming days.
The area to watch: The National Hurricane Center has outlined an area between Cuba and Mexico's Yucatan Peninsula for the possible formation of a tropical depression or storm in the next seven days. At this time, there is no system to track in this region, as the general lack of storminess in the satellite view below shows.
What could happen by early next week is that a broad area of low pressure forms in association with what's called the Central American Gyre, giving rise to increasingly stormy weather. That's when we'll watch this region closely for tropical development.
When a tropical storm could develop: The first half of next week is the earliest chance a tropical depression or storm might form in the northwest Caribbean or southern Gulf from this broad area of low pressure. The next storm names are Helene and Isaac.
For that to happen, the broader low would need to spin off a more well-defined low-pressure system with persistent shower and thunderstorm activity.
If a storm forms, here's where it might track: This possible storm could track north or northeast toward the U.S. Gulf Coast or northwest toward the Yucatan Peninsula and then the southwest Gulf.
The greater the influence from that jet stream, the more likely the system would get drawn north toward the U.S. Gulf Coast. If it has less of an influence, then the system might move northwest toward the Mexico's Yucatan Peninsula and the southwest Gulf, with its future track beyond that point uncertain.
The timing of any potential U.S. impact might not be until at the earliest late next week or beyond.
Could it become a hurricane? It's certainly possible. Oceanic heat content is one favorable ingredient for intensification, and the map below shows there is plenty of deep, warm water in the northwest Caribbean and parts of the Gulf of Mexico.
But there are other factors that also matter, like whether or not the upper-level wind pattern is favorable for strengthening. It’s also unknown if any nearby dry air or land interaction, such as with Mexico's Yucatan Peninsula, could be hindrances to intensification.
For now, interests along the U.S. Gulf Coast should monitor the situation closely while also making sure hurricane preparedness plans are in place. Check back with us at weather.com and The Weather Channel app for updates through the weekend and beyond as we fill in more details on what to expect.
