A forecast map from the National Hurricane Center has tracked a developing system in the eastern Pacific that's poised to strengthen into a tropical storm.
If it does, it will take the name Tropical Storm Dalila.
Why It Matters
The 2025 eastern Pacific hurricane season began on May 15 and has already seen the formation of Tropical Storms Alvin, Barbara and Cosme. Dalila, which is expected to form on Friday, would become the fourth named storm system of the season.
The NHC said the system could bring periods of heavy rainfall to parts of Mexico—including the states of Guerrero, Michoacán and Colima—through the weekend. These downpours may lead to localized flooding and mudslides, particularly in steep terrain.
What To Know
The NHC's map indicates the system will track north and west parallel with Mexico's southwestern coast.
Designated a potential tropical cyclone at the time of writing, the system is anticipated to strengthen and reach tropical storm status later on Friday, according to the agency.
This map from the National Hurricane Center shows the predicted path for Potential Tropical Cyclone Four-E, which is expected to strengthen into Tropical Storm Dalila.

Forecasters at Fox Weather said the system was forecast to follow a path much like Barbara's, which quickly weakened as it moved north over cooler waters. Similarly, the outlet anticipated that Dalila would have limited effects on land.
The NHC said tropical storm watches were in effect for the coast of southwestern Mexico.
What People Are Saying
National Hurricane Center Pacific said in a Friday morning update on X, formerly Twitter: "Potential Tropical Cyclone #Four-E Advisory 3: Disturbance Expected to Become a Tropical Storm Later Today. Tropical Storm Watch Remains in Effect For the Coast Of Southwestern Mexico."
Meteorologist Phil Ferro wrote on X on Thursday: "Thursday Evening Potential Storm 4-E Advisory & Cone. It's forecast to become a full tropical storm Friday. It will be named Dalila. It should run into a high pressure dome, bounce off it, and get redirected away from Western Mexico."
Meteorologist Ryan Maue wrote on X on Thursday: "A tropical storm (Dalila) will form in the next 48-hours off southern coast of Mexico in the Eastern Pacific and probably become a hurricane."
AccuWeather senior meteorologist Tom Kines previously told Newsweek: "There's no doubt three named storms so early is highly unusual. The first hurricane doesn't usually occur until last week of June."
What Happens Next
The National Oceanic and Atmospheric Administration is predicting a likely below-normal season this year in the eastern Pacific, with 12 to 18 named storms expected. Of those, five to 10 may strengthen into hurricanes, and two to five could reach major hurricane status.
The 2025 eastern Pacific hurricane season runs through November 30.
