Tropical Storm Karina is now projected to strengthen into a major hurricane as more forecasting models show a potentially destructive path to California.
The National Hurricane Center (NHC) revealed that Karina, which currently has sustained winds of more than 50 mph, is expected to reach hurricane status as early as Friday night.
By Sunday morning, forecasts show the giant cyclone strengthening into a Category 3 hurricane, meaning its winds will exceed 111 mph.
New spaghetti models, which track all possible paths of tropical storms and hurricanes, show multiple routes that would take Karina straight into the California Coast, potentially impacting millions of Americans.
Early predictions from the American forecasting model, known as GFS, showed several possibilities for a historic landfall in San Diego or Los Angeles.
The so-called European model, also known as the EPS Ensemble, was more skeptical of a US landfall on Thursday, predicting that Karina would stay away from the California Coast and move out to sea.
However, both prediction models were updated on Friday, with both now showing potential paths to Southern California and points further north.
A hurricane has never made landfall in California in recorded history, according to the National Weather Service, and the last time a tropical storm directly impacted the state was in 1997.

Forecasts predict Karina will reach hurricane status by Friday night
A tropical storm has not taken such a path, from the Pacific Ocean straight into the California Coast, in nearly a century, when the Long Beach Tropical Storm landed in 1939.
It is important to note that forecast models can shift dramatically once storms form and get closer to making landfall. The farther into the future a forecast model tries to predict, the weaker the certainty of it being correct gets.
Spaghetti models, which show a large sampling of weather predictions, also reveal a great amount of uncertainty about a hurricane when they show paths going in several different directions – which is the current case with Karina.
The more tightly clustered the spaghetti models are, the more confident meteorologists are in the route of a storm.
Tropical Storm Karina is currently less than 1,400 miles south from San Diego and is moving northwest at 13 mph far offshore from the coast of Mexico.
Three years ago, Hurricane Hilary impacted Southern California, but weather officials later determined that the storm was no longer a named cyclone when it made landfall.
The last time the state was struck by an actual tropical storm was in 1997 when a weakening Hurricane Nora crossed from Mexico into the US still at tropical storm strength.
In 2026, AccuWeather’s lead long range forecaster Paul Pastelok has warned that the stage is set for a historic storm to reach California, thanks to the emergence of the weather phenomenon El Niño.

El Niño is a natural weather phenomenon that simply means that the Pacific Ocean has become noticeably warmer than its historical average.
However, this warming flips global weather patterns, causing storms to become more potent and capable of lasting longer in the Pacific, while weakening in the Atlantic.
AccuWeather meteorologists have predicted that this year’s El Niño will likely be the strongest in recorded history, with sea-surface temperatures in the Pacific rising by 4.8°F (2.66°C).
This would count as a ‘Super’ El Niño, meaning Pacific temperatures have risen by more than 3.6 degrees Fahrenheit (2.0 degrees Celsius).
This is a breaking story. More details to follow.
