On June 1, Typhoon No. 1 Alvin in the 2025 Northern Hemisphere's typhoon season weakened into a post-tropical cyclone, ending a short but warning journey in the waters of the eastern Pacific, off the coast of Mexico.
However, as the name Alvin has just been removed, a new low pressure has appeared, even with the potential to become the next storm - storm No. 2 Barbara.
Alvin was named on May 28, just one day after forming off the southern coast of Mexico. The storm's strongest winds reached 96 km/h on May 29, before weakening rapidly due to entering cool water and unfavorable atmospheric conditions. As of the morning of May 31 (local time), Alvin was still a post-tropical cyclone with maximum sustained winds of 56 km/h.
Although the storm has dissipated, large waves and the Alvin-caused offshore flows still affect the western coastal areas of Mexico and Baja California peninsula. Authorities warn of the risk of life-threatening offshore flows, especially for tourists.
As soon as Alvin dissipated, the US National Hurricane Center (NHC) shifted its attention to a new low pressure area located near where Alvin had formed, in the sea between Mexico and Guatemala.
This low pressure has been upgraded to an "average" level in terms of development potential within the next 7 days.
Storm models predict that the low pressure may strengthen in the middle of next week, with a high probability of becoming a tropical storm Barbara by the end of the week, as sea temperature and upper winds become more favorable.
FOX Weather meteorologist Bryan Norcross said: The 2025 Pacific hurricane season is on schedule. The sea off the southern coast of Mexico is warm enough and the current atmospheric model is very favorable for the formation of tropical cyclones.
The warming of the ocean's water is always a decisive factor in the formation and development of storms. The 26 degrees Celsius water level is considered warm enough to provide energy for the storm to strengthen. Currently, many areas of the eastern Pacific are maintaining this temperature, while some others are cooler, making the storm's path unpredictable.
According to the forecast of the Mexico Meteorological Agency, the 2025 typhoon season in the Pacific will have more typhoons than average, with about 18 named storms and 10 hurricanes reaching typhoon level (hurricane level).
The storm season in the East Pacific lasts from May 15 to November 30, and the early appearance of Typhoon No. 1 Alvin - despite weakness - along with a new low pressure has signaling a busy storm season ahead.
