Areas where tropical development is possible in the coming days are highlighted above. The red area over the Atlantic’s main development region is the most concerning.
El Niño has been hitting the snooze button on Atlantic hurricane season for weeks, largely preventing the basin from waking up and churning up storms, but at least one potential tropical troublemaker has a chance to shake the season out of its slumber
The National Hurricane Center is outlooking an area in the tropical Atlantic that has about a 70% or “high” chance of becoming at least a tropical depression late this week. There’s also another area in the northern Atlantic that has a much lower chance to develop, and only in the next day or two
The next tropical storm that forms anywhere in the basin will be named Cristobal

Mid-August is typically when the tropics enters its busiest stretch, but any upcoming contenders for tropical development are going to be fighting an uphill battle to form and stay alive against El Niño’s influence
The main challenge these systems face is El Niño’s abundant storm-killing wind shear. It’s a force that’s more likely to stick around as El Niño grows into a potentially record-breaking Super El Niño in the coming months
Wind shear is a change in wind speed or direction at different levels in the atmosphere that can prevent storms from forming in the first place, keep them from strengthening or tear them apart completely. It’s now firmly in place over what should be the most active parts of the Atlantic
Air rises above the warmer Pacific (El Niño conditions), then sinks down over parts of the western Atlantic basin, helping suppress the storms that could grow into a tropical system.
The sinking air over the western half of the Atlantic basin, coupled with increased wind shear, is what tamps down tropical activity during El Niño.
This is the exact setup that prompted numerous predictions for a below-average season in the first place. Hurricane season has certainly been living up to those expectations so far: It’s been the least active start to the season since 2009
Arthur and Bertha have been the only tropical storms to date. Both came alive right along the Gulf Coast and were battered by wind shear every step of the way, which prevented them from strengthening significantly and limited their impacts overall
The upcoming tropical chances may face a similar story, just in different locations
The area outlooked with the high chance in the eastern Atlantic marks the first time all season a system could actually form somewhere other than near the United States’ coastline
This area of the Atlantic — called the main development region — should be getting very active at this point in a typical season as wind shear relaxes and ocean temperatures soar, providing tropical systems with ample fuel
But thanks to El Niño, that wind shear remains stubbornly in place and has recently become record strong a hurricane expert with Colorado State University
There could be a window after Wednesday for the potential system with a high chance of development to get enough of a boost of energy to overcome some of the shear
It could become a tropical depression as soon as Thursday as it tracks west across the tropical Atlantic. But it’s unclear how much stronger it could become
Computer forecast models are also still uncertain exactly where the system could track from there. Some take it toward the eastern Caribbean late this weekend, where it would face more wind shear. Others curve the system northeast of the region, where it could eventually escape the worst shear and head toward the open Atlantic if it survives that long
The other potential development area has a slimmer time frame to spin to life before conditions get more hostile around midweek
A normal Atlantic hurricane season typically has at least three tropical storms by August 3 and four by August 15. Bertha — the season’s second storm and the last to roam anywhere in the basin — impacted the US Gulf Coast in late July
The season is also behind on hurricanes: The first hurricane of the season typically forms around August 11. Hurricane Erin formed just a few days after that threshold in 2025 and 2024 had already seen two hurricanes by that point
Mid-August to mid-October is when most tropical storms and hurricanes form, so there’s still plenty of time for tropical systems to make an attempt. However, multiple groups including the National Oceanic and Atmospheric Administration and Colorado State University are growing increasingly confident in their forecasts for a muted season overall
NOAA released a forecast update last week that upped their chances of a below-average season from 55% to 75%. That forecast also notably dropped its range for the overall number of major hurricanes — Category 3 or greater — from one to three to zero to two
If the 2026 season ends without a major hurricane, it would be the first time without such a powerful storm since 2013
