The Miami, Florida-based National Hurricane Center says they expect Tropical storm Dalila to form today in the Eastern Pacific which would make it the fourth named storm of the 2025 hurricane season which started in that basin on May 15. While Dalila is expected to form today, the National Hurricane Center expects the Atlantic basin, where Hurricane Season began on June 1, to remain quiet for at least the next 7 days.
With tropical storm formation likely, the Mexican government has issued a Tropical Storm Watch for the area between Tecpan De Galeana and Manzanillo. A Tropical Storm Watch means that tropical storm conditions are possible within the watch area, generally within 48 hours. The National Hurricane Center cautions that a Tropical Storm Warning may be required for portions of the watch area later today; Tropical Storm Watches may also need to be issued north up the coast.
As of the latest advisory from the National Hurricane Center (NHC), the developing storm system, now known as “Potential Tropical Cyclone 4-E”, is located about 295 miles south of Zihuatanejo, Mexico. With maximum sustained winds of 35 mph the storm system has a minimum central pressure of 1006 mb or 29.71″.
This system is moving toward the north-northwest near 9 mph . A turn toward the northwest is expected later today by the NHC, with a turn toward the west-northwest forecast by Sunday. On the forecast track, the disturbance is forecast to move parallel to, but offshore of, the southwestern coast of Mexico. As it advances up the coast, strengthening is expected during the next couple of days. The system is forecast to become a tropical storm later today and continue strengthening on Saturday as it moves parallel to the coast of southwestern Mexico.
Once the system is classified as a Tropical Storm it would be named Dalila.
Rainfall totals of 2-4″, with localized amounts up to 6″, are possible across portions of the Mexican states of Guerrero, Michoacán, and Colima through this weekend. This rainfall may lead to areas of flooding and mudslides. Swells generated by the developing system will affect portions of the coast of southwestern Mexico during the next few days. These swells are likely to cause life-threatening surf and rip current conditions.
