Tropical Storm Alvin 2025: These cities of Eastern Pacific will face hurricane

A tropical storm is forming in the eastern Pacific Ocean and is expected to become the first named cyclone of the 2025 season. The system, which could soon be named Tropical Storm Alvin, is organizing several hundred miles south of the Mexican coast. The National Hurricane Center (NHC) has reported a near-100% chance of tropical development within the next 48 hours. If confirmed, Alvin would mark an early start to the Pacific hurricane season, which officially began on May 15.

Where is Tropical Storm Alvin?

As of Tuesday, May 27, satellite imagery showed clusters of showers and thunderstorms developing near a low-pressure system off the coast of southern Mexico. Though the storm does not yet have a well-defined circulation, forecasters say environmental conditions—such as warm ocean waters and low wind shear—are favourable for further strengthening. The system is currently moving in a west-northwest direction at around 10 miles per hour.

If Alvin continues to strengthen, it could reach tropical storm status by Wednesday and potentially become a hurricane by Thursday. Forecast models indicate the storm will likely track west-northwest before turning slightly north.

By the weekend, it could encounter less favourable conditions, such as cooler waters and stronger wind shear, which may weaken it. There is still uncertainty about whether Alvin will dissipate at sea or move toward the Mexican coast in a weakened state, according to AccuWeather.

Even if the storm remains offshore, parts of Mexico’s Pacific coastline could still face dangerous impacts. High surf and strong rip currents are expected west of Acapulco later this week. Bands of heavy rain could also lead to flash flooding and mudslides, particularly in mountainous regions. These risks will increase depending on how close the storm moves to the coast and how much it intensifies in the coming days.

When does 2025 Atlantic hurricane season begin?

The Atlantic hurricane season starts on June 1 and ends on November 30. It lasts for six months. Some storms have formed early in May in recent years. The busiest time of the season is usually around September 10.

The development of Alvin would place it well ahead of the historical pace for tropical storms in the Pacific. On average, the first named storm of the eastern Pacific season forms around June 10.

Last year, the first storm—Aletta—did not form until July 4, making it the latest start to the season in the satellite era. This year’s early activity suggests a shift in patterns, though the overall Pacific season is still expected to be less active than average.

According to NOAA’s seasonal forecast released on May 22, the eastern Pacific is likely to see a below-average number of storms in 2025. Meanwhile, the Atlantic hurricane season, which begins on June 1, is expected to be more active than normal, with 13 to 19 named storms predicted. Of those, 6 to 10 may become hurricanes, and 3 to 5 could reach major hurricane strength.

Timeline of events

Tropical Storm Alvin is not expected to affect the United States directly. Eastern Pacific storms typically stay out to sea and rarely make landfall in the U.S. However, past storms like Hurricane Hilary and Hurricane Otis have shown that powerful Pacific cyclones can still cause significant damage if they strike land. Forecasters will continue to monitor Alvin’s development and update projections as new data comes in.

As of now, people along Mexico’s Pacific coast should remain alert to changing weather conditions. The potential for coastal hazards like flooding and rough surf will become clearer as the storm’s path and strength evolve over the next few days.
