Tropical Depression 05E formed on July 11, 2016, off the coast of western Mexico and strengthened into a tropical storm named Darby on July 12. By 21:00 UTC on July 13, Darby became the third hurricane of the 2016 eastern Pacific hurricane season. Additional strengthening is forecast during the next 48 hours.
At the time, the center of Hurricane "Darby" was located about 920 km (570 miles) SSW of the southern tip of Baja California, Mexico. Its maximum sustained winds were 120 km/h (75 mph), making Darby a Category 1 hurricane on the Saffir-Simpson Hurricane Wind Scale. The system was moving west at 19 km/h (12 mph), and this general motion is expected to continue during the next few days. Its minimum central pressure was 992 hPa.

At 03:00 UTC on July 14, Darby's center was located about 950 km (590 miles) SSW of the southern tip of Baja California. Its maximum sustained winds have increased to near 130 km/h (80 mph). The system is still moving west at 20 km/h, with minimum central pressure of 989 hPa.
Hurricane-force winds extend outward up to 35 km (25 miles) from the center and tropical-storm-force winds extend outward up to 150 km (90 miles).
There are no coastal watches or warnings in effect.
At the same time, the center of Tropical Storm "Celia" (04E) was located about 2 130 km (1 325 miles) east of Hilo, Hawaii. Celia, the second hurricane of the 2016 eastern Pacific hurricane season, was moving toward the west-northwest near 20 km/h (13 mph), with maximum sustained winds near 85 km/h (50 mph).
Additional weakening is forecast, and Celia should degenerate into a remnant low during the next couple of days. Its estimated minimum central pressure was 1 000 hPa. Celia officially lost its hurricane status at 09:00 UTC on July 13.
