As of Monday, September 14, 2026, the National Hurricane Center is tracking two systems in the eastern Pacific, but neither currently represents an immediate threat to the U.S. mainland. Tropical Storm Norbert is moving west-northwest and is expected to weaken, while Tropical Depression Fifteen-E could strengthen into a named tropical storm later Monday. The Atlantic, Caribbean and Gulf of America have no active tropical cyclones.
Norbert is expected to weaken over open water
Tropical Storm Norbert is located well east of Hawaii and far west of the southern tip of Baja California. The storm has maximum sustained winds of roughly 40 to 45 mph, latest advisory cycle, and is moving generally west to west-northwest.
The National Hurricane Center says Norbert should gradually weaken during the next several days. Forecast guidance has the system moving farther into the Pacific before it becomes a remnant low and dissipates. No coastal watches or warnings are in effect, and the storm is not forecast to make landfall.
That distance matters. Tropical systems can produce large swells and rough marine conditions well away from their centers, but Norbert’s current forecast track keeps the core of the storm over open water. For residents of Hawaii, the mainland United States and Mexico, the main takeaway is that the system is being monitored, not that a direct land impact is expected.
Fifteen-E could become the next named storm
Tropical Depression Fifteen-E is southwest of the southern tip of Baja California. Its maximum sustained winds are near 35 mph, just below the 39-mph threshold required for classification as a tropical storm.
Forecasters say the depression could become a tropical storm later Monday or early Tuesday if it gains enough organization and strength. The system is moving west-southwest to west over the eastern Pacific, and the current forecast keeps it away from land in the near term.
Even when a depression strengthens, that does not automatically mean a U.S. land threat is developing. The most important details are the storm’s direction, forward speed, wind field and interaction with surrounding atmospheric conditions. Those elements can change over several forecast cycles, which is why the National Hurricane Center updates its advisories regularly.
The Atlantic is quiet, but forecasters are watching one disturbance
The National Hurricane Center reports no tropical cyclones in the Atlantic basin. It is, however, monitoring a trough of low pressure more than 1,000 miles east-southeast of Bermuda. The disturbance is producing disorganized showers and thunderstorms.
Development is considered unlikely during the next 48 hours because of strong upper-level winds. The system could encounter more favorable conditions later in the week as it moves west-northwest across the central subtropical Atlantic. The center currently assigns it a low chance of formation during the next seven days.
That outlook is not a storm warning or a prediction of landfall. A formation percentage describes the chance that a disturbance will organize into a tropical depression or storm. It does not indicate the likelihood that a particular city will be affected.
Why the forecast is drawing attention
Interest in tropical storm forecasts typically rises during the peak portion of hurricane season, when people are checking travel plans, coastal conditions and possible threats to homes and businesses. September is also a period when weather systems can develop quickly, making official updates more useful than broad seasonal expectations.
NOAA’s updated 2026 Atlantic outlook calls for a below-normal season to be the most likely outcome. But NOAA also emphasizes that a seasonal outlook is not a landfall forecast. A relatively quiet basin can still produce a dangerous storm, while a busy season may send many systems away from the coast.
What to watch next
The next important developments are straightforward: whether Fifteen-E becomes a named storm, how quickly Norbert loses tropical characteristics and whether the Atlantic disturbance becomes better organized later this week.
Readers in coastal areas should rely on the National Hurricane Center and local National Weather Service offices for watches, warnings and location-specific guidance. Forecast cones and formation probabilities are useful planning tools, but they should not be treated as guarantees. For now, the latest tropical storm weather forecast points to active monitoring in the Pacific, a quiet Atlantic and no confirmed immediate U.S. mainland threat from the systems currently being tracked.
