Hurricane Otis is an active, explosively intensifying tropical cyclone in the eastern Pacific Ocean, currently threatening the Mexican state of Guerrero. The fifteenth storm, tenth hurricane and eighth major hurricane of the 2023 Pacific hurricane season, Otis originated from a disturbance several hundred miles south of the Gulf of Tehuantepec.

The NHC first noted on October 15 that an area of low pressure was expected to form south of Guatemala and El Salvador by the middle of the week.[1] A broad low-pressure area formed several hundred miles south of the Gulf of Tehuantepec on October 18 and was generating disorganized thunderstorms.[2] The system increased in organization over the next few days, becoming a tropical depression at 15:00 UTC on October 22. At that time, the depression had strong, increasing convective activity near its well-defined center.[3] Six hours later, the depression became a tropical storm and received the name Otis following a slight increase in organization. The nascent storm was moving slowly northward as it was located within a light steering flow between a low-pressure trough to its northwest and a high-pressure ridge to its northeast.[4] Overnight, deep convection pulsed on the northwestern portion of the circulation with the center becoming more embedded in the colder cloud tops.[5] However, this convective trend plateaued in the early hours of October 23 due to easterly wind shear, which hindered further organization and left the center partially exposed.[6] By 03:00 UTC on October 24, microwave satellite imagery depicted a low-level ring structure in the 37 GHz channel, despite the overall sheared appearance of the system. The NHC noted the imagery as possible evidence for an imminent rapid intensification event.[7]

Current storm information

As of 7:00 p.m. CDT October 24 (00:00 UTC October 25), Hurricane Otis is located within 20 nautical miles of 15°42′N 99°36′W / 15.7°N 99.6°W / 15.7; -99.6 (Otis), about 85 miles (135 km) south-southeast of Acapulco, Mexico. Maximum sustained winds are 145 mph (230 km/h), gusts up to 175 mph (280 km/h). The minimum barometric pressure is 941 mbar (27.79 inHg), and the system is moving north-northwest at 8 mph (13 km/h). Hurricane-force winds extend outward up to 30 miles (45 km) from the center, and tropical storm-force winds extend outward up to 70 miles (115 km).

Preparations and impact

Guerrero

In response to the approach of Hurricane Otis the Guerrero Government began preparing 396 shelters to accommodate residence displaced by wind and surge damage. Mexico's army and navy sent 8,000 troops to support aid and rescue operations. Authorities in Guerrero closed Acapulco's main port.[8] Schools across Guerrero were to be closed ahead of Otis anticipated landfall.[9]
