Storm type
triangle Extratropical cyclone, remnant low, tropical disturbance, or monsoon depression

On August 12, a tropical wave traversing Central America producing widespread rain showers and thunderstorms entered the far eastern Pacific.[19] A broad area of low pressure developed within the wave on August 14, off the southern coasts of Mexico, Guatemala, and El Salvador.[20] The disturbance gradually became better organized during the following day, and when a well-defined circulation along with developing convective banding features were observed on the morning of August 16, it was classified as Tropical Storm Hilary by the National Hurricane Center (NHC).[21] Convection near the storm center increased as the day progressed, dense overcast started to develop over the growing storm as a result, and an eye began to form at its center.[22] Consequently, Hilary quickly strengthened into a Category 1 hurricane by 12:00 UTC on August 17, while located about 320 mi (515 km) southwest of Manzanillo, Colima.[23] It then proceeded to rapidly intensify, reaching Category 4 strength at 06:00 UTC the following morning.[24]

As of 6:00 p.m. MDT (00:00 UTC) August 18, Hurricane Hilary is located within 15 nautical miles of 19°06′N 112°24′W / 19.1°N 112.4°W / 19.1; -112.4 (Hilary), about 95 mi (155 km) west of Socorro Island and about 310 mi (500 km) south-southwest of Cabo San Lucas, Mexico. Maximum sustained winds are 130 mph (215 km/h), with gusts up to 160 mph (260 km/h). The minimum barometric pressure is 948 mbar (27.99 inHg), and the system is moving northwest at 12 mph (19 km/h). Hurricane-force winds extend outward up to 50 mi (80 km) from the center and tropical storm-force winds extend outward up to 275 mi (445 km).
