Tropical Storm Vance, which formed on Wednesday, October 21, 2026, as the twenty-third named storm of an unusually active 2026 Pacific hurricane season, strengthened into a hurricane and peaked as a Category 2 hurricane with maximum sustained winds of 110 mph on 23 October — but it never became the major hurricane forecasters had warned it could become by the weekend. Instead, wind shear tore at the storm, and by 2am on Wednesday, 28 October, it had weakened back to a tropical storm with maximum sustained winds of 40 mph about 280 miles west of Manzanillo, with no coastal watches or warnings in effect.

In its 9:00 AM CST advisory on Thursday, October 22, the U.S. National Hurricane Center (NHC) placed Vance's center near latitude 9.7 degrees north and longitude 101.0 degrees west — about 505 miles (810 km) south of Acapulco, Mexico, and roughly 680 miles (1,095 km) south-southeast of Manzanillo. Maximum sustained winds had increased to near 60 mph (95 km/h) with higher gusts, and the storm was drifting toward the northwest at just 3 mph (6 km/h). The estimated minimum central pressure was 997 millibars, and tropical-storm-force winds extended outward up to 90 miles (150 km) from the center.

The NHC forecast calls for Vance to keep strengthening, reaching hurricane strength — sustained winds of at least 74 mph — tonight or early Friday, October 23. From there, the storm could continue intensifying into a major hurricane by the weekend, meaning Category 3 or higher with winds of at least 111 mph. Forecasters have specifically flagged the potential for rapid intensification as Vance moves over very warm Pacific waters with favorable upper-level conditions.

Rapid intensification happens when a tropical cyclone's maximum sustained winds increase by at least 35 mph in 24 hours. It requires a near-perfect setup: warm ocean water to feed the storm, low wind shear so the storm's structure is not torn apart, and moist air through a deep layer of the atmosphere. When those ingredients align — as they currently are over the eastern Pacific — a storm can jump categories in a single day, which is why forecasters treat rapid intensification as one of the most dangerous aspects of tropical cyclones: it shrinks the window communities have to prepare.

Where exactly Vance goes remains the biggest question. The latest NHC forecast shifted the projected track well to the northeast, near a blend of the latest American (GFS) and European (ECMWF) computer models. Some model runs keep Vance's core entirely offshore, while others bring it closer to Mexico's west coast or the Baja California peninsula. Forecast guidance even shifted substantially overnight as a mid-level ridge over Mexico weakened faster than expected, and some advanced modeling aids sit more than a degree east of the official forecast by day four — a reminder that long-range tropical forecasts carry real uncertainty.

Even if Vance's center stays offshore, Mexico's coastline will feel it. The NHC warns that swells generated by Vance are expected to begin affecting portions of the southern and southwestern Mexico coast this weekend and continue into next week, likely causing life-threatening surf and rip current conditions. In the Los Cabos region at the tip of Baja California Sur, local authorities say there is no immediate threat and no reason to cancel travel plans, but they are advising residents and tourists to keep a close eye on the forecast as the traditionally quiet late-October period delivers one last curveball.

Alex DaSilva, AccuWeather's lead hurricane expert, warned that residents and businesses across western Mexico should closely monitor Vance's progress. "The exact track of the storm will play an important role in determining the severity of impacts to western Mexico, or whether the storm remains offshore entirely," DaSilva said. The next complete NHC advisory was scheduled for 3:00 PM CST, with updates issued every six hours as long as the storm remains a forecasting challenge.

Vance could also have ripple effects far beyond Mexico. DaSilva noted that leftover tropical moisture from the storm's remnants could move into Texas and Oklahoma next week, potentially bringing heavy rain to parts of the southern United States. It would not be the season's first cross-border moisture story: earlier this month, Tropical Storm Rachel slammed Southern California, a reminder that eastern Pacific systems can reach deep into the U.S. Southwest.

Vance arrives as the 2026 Pacific hurricane season refuses to wind down. The season officially runs through November 30, and this year's crop of storms has been unusually prolific — Vance is already the twenty-third named system. Earlier in October, Hurricane Trudy rapidly intensified off Mexico's Pacific coast with a forecast track toward Colima and Jalisco, while Hurricane Simon reached Category 4 strength in the same waters. In the Atlantic, meanwhile, Storm Josephine is spinning out without threatening land.

Forecasters are also watching a separate area of disturbed weather in the central Pacific, a few hundred miles west of Hawaii and west-southwest of Johnston Atoll. The NHC gives it a medium chance of developing into a tropical depression or storm between October 25 and 28, with environmental conditions appearing conducive for gradual development over the next seven days.

The setup echoes Hurricane Trudy earlier this month, which strengthened to 90 mph off Mexico's Pacific coast on October 15 and was forecast to rapidly intensify into a Category 4 major hurricane as it approached Colima and Jalisco — a case study in how quickly eastern Pacific storms can escalate when ocean heat and atmospheric conditions align.

Vance is not the only storm making headlines this week. In Europe, deadly flooding has struck southern France, where at least four people died as storms battered the region and Storm Austen bore down on the northwest — while earlier in the month, Storm Adam brought deaths and evacuations to eastern Spain.

How Vance Weakened: From 110 mph to a Remnant Low

Vance never made landfall. The National Hurricane Center expected it to become a post-tropical remnant low on Thursday, 29 October, as it neared the coast of northwestern Mexico, and issued its final advisory that evening, when Vance no longer had a well-defined centre and its maximum sustained winds had fallen to 30 mph. Its remnant moisture was expected to spread into western Mexico and the south-central and southwestern United States. The storm's main legacy on land was rain: the NHC forecast 2 to 4 inches across central and southern Sinaloa, western Durango and northwestern Nayarit, with isolated totals up to 7 inches in Sinaloa, bringing a risk of flash flooding and mudslides.
