Hurricane Jova, churning west across the open Pacific Ocean, strengthened into a major Category 5 hurricane for a time in the Eastern Pacific. However, the storm poses no immediate threat to land, AccuWeather hurricane experts say.
The powerhouse hurricane, the first to achieve Category 5 status on the Saffir-Simpson Hurricane Wind Scale in the basin since there were three such storms in 2018, may soon have company in the Atlantic, as Hurricane Lee strengthens into this weekend. AccuWeather, however, does not expect both hurricanes to be at their peak strength at the same time. Advertisement
A Category 5 hurricane is one with maximum sustained winds of at least 157 mph, the highest category on the scale.

As of Friday morning, local time, Jova was centered about 550 miles to the southwest of the southern tip of Baja California, Mexico, and was moving away from the country, to the west-northwest at 16 mph.
“Jova will track to the northwest through the weekend and is not expected to bring direct impacts to land,” AccuWeather meteorologist Brandon Buckingham said. “It will, however, bring rough surf and rip currents to the west coast of Mexico and potentially into coastal Southern California.”
Packing maximum sustained winds of 155 mph, Jova was a Category 4 hurricane, down from peak intensity at Category 5 status with 160-mph winds from Wednesday evening into early Thursday. A gradual loss of wind intensity is expected to continue through Friday and the weekend, as Jova moves over colder waters in the open Pacific, AccuWeather forecasters say.
While the loss of wind intensity for Jova will be slow to occur, its ramp-up to Category 5 status on Wednesday happened at a tremendously fast rate. When the day began, Jova had just become a hurricane, with 85-mph winds, and by the time the day was over, it was a Category 5 storm, with 160-mph winds.
The pace of increase in Jova’s wind intensity was more than double the National Hurricane Center’s official definition for rapid strengthening, which is an increase of 35 mph over a 24-hour period. Over just an 18-hour period on Wednesday, Jova gained 75 mph of wind intensity. The storm’s minimum central pressure also fell by 1.89 inches of mercury (64 millibars) in a 24-hour period, also indicative of explosive strengthening.

On Thursday morning, Jova exhibited a symmetrical “buzzsaw” shape and a clear eye on satellite imagery, cementing its status as the strongest storm the Western Hemisphere has seen so far in 2023.
With AccuWeather forecasting Hurricane Lee in the Atlantic Ocean to become a Category 5 hurricane soon as well, a question has arisen: Have there ever been two concurrent hurricanes at peak scale intensity in both basins? The answer is no — at least not since reliable records began earlier last century.
As Jova slowly continues to lose wind intensity late this week and Lee gains it into this weekend, it appears that the milestone of Category 5 hurricanes churning across both basins at the same time will be missed again.
This year, however, would become only the second on record where each basin records at least one Category 5 hurricane, if Lee achieves that status this weekend, as forecast by AccuWeather. The last time that occurred was in 2018 when Lane, Walk and Willa roamed the Pacific and Michael churned in the Gulf of Mexico.

It is possible that prior to the 1960s multiple Category 5 hurricanes roamed each ocean at the same time, but it is impossible to know for sure since the first weather satellite, TRIOS, was not launched until 1960. Advertisement
Jova also became the first Category 5 hurricane in the Eastern Pacific since Willa achieved that status on Oct. 22, 2018.
The last Category 5 hurricane in the Atlantic occurred just last year (Ian on Sept. 28).
