The typhoon season in the East Pacific is entering an unusually vibrant period with 3 consecutive storms forming in less than 1 month and not stopping there. The latest tropical storm, Cosme, has just been officially named and is likely to strengthen into a Category 1 storm in the next few days.
According to the US National Hurricane Center (NHC), Cosme developed from tropical depression 3-E on the afternoon of June 8 (local time), with maximum sustained winds of 80 km/h - the official threshold to be classified as a tropical storm.
On June 9, Cosme moved about 1,015 km southwest of the extreme south of Baja California peninsula (Mexico). It is forecasted that by the morning of June 10, the storm will slow down, then turn northeast and accelerate again from late June 10 to June 11.
Although not expected to make landfall, Cosme could have an indirect impact with high waves and heavy rains along the coast of Mexico.
Notably, Cosme is the third named storm of the 2025 typhoon season in the eastern Pacific, after Typhoon No. 1 Alvin (dispersed) and Typhoon No. 2 Barbara, which are still active east of Cosme.
Hurricane Barbara is bringing heavy rain and strong waves to the west coast of Mexico, although it is unlikely to make landfall.
Not stopping there, the fourth storm could appear this week. According to AccuWeather's storm forecast, the sea area from June 13-15 is likely to form a new tropical cyclone. If it develops into a tropical storm, it will be named Dalila and is likely to affect Mexico.
AccuWeather meteorologist Alex DaSilva said: This year's storm season in the eastern Pacific has started unusually quickly. Last year, it was not until July 4 that the first storm was named.
Meanwhile, historically, Typhoon No. 2 was recorded around June 24, Typhoon No. 3 on July 6 and Typhoon No. 4 on July 15.
The East Pacific typhoon season runs from May 15 to November 30 every year. With the current acceleration, 2025 is likely to be a vibrant and unusual storm season, requiring countries along the Pacific Ocean to be highly vigilant.
