The tropical storm had maximum sustained winds at 40 mph (65 kph) and is moving at 13 mph (20 kph) . Dalila was expected to bring up to 6 inches (15 centimeters) of rain to parts of Guerrero, Michoacán, and Colima states on Saturday.

Most spaghetti models, or computer models illustrating potential tropical cyclone paths, show the storm veering west into the Pacific, although one shows it taking a more northerly track through Mexico, with some impacts such as heavy rain possibly stretching into the U.S. Southwest.

The National Hurricane Center said Tropical Storm Dalila has formed in the Pacific and will continue strengthening in the next couple of days.
