Tropical Storm Dalila formed in the North Pacific Ocean Friday morning Mexico Central Time, according to the National Hurricane Center. The tropical storm had sustained wind speeds of 40 miles per hour.

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 a tropical storm is expected to form in the Pacific Ocean on Friday and continue strengthening on Saturday.
