Sandra developed over the warm eastern Pacific waters on November 24, 2015 and quickly intensified into a hurricane. The system is now a major Category 4 hurricane, about 800 km southwest of Mexico and moving northwards. The hurricane poses no threat to the mainland at the moment, however the states of Nayarit, Jalisco, Colima, Michoacan, Guerrero and the islands of the Revillagigedo Archipelago could receive large amounts of rainfall over the next 24 hours.

Tropical Storm "Sandra" formed on November 24 and intensified into a hurricane on November 25. Sandra has continued to intensify and is now a Category 4 hurricane system, thus becoming the season's latest major hurricane on record.

Hurricane "Sandra" was located about 810 km (500 miles) southwest of Cabo Corrientes Mexico and 925 km (575 miles) south of the southern tip of Baja California and moving north at 19 km/h (12mph), on November 26, 09:00 UTC, according to NHC. Maximum sustained winds were estimated at 230 km/h (145 mph) with gusts reaching 277.8 km/h (172.6 mph). Minimum central pressure of the system was 935 hPa at the time.

Winds of hurricane force extend up to 55 km (35 miles) from Sandra's center, and tropical storm force winds currently extend up to 185 km (115 miles) outward.

Sandra is expected to turn toward north-northeast on November 27 and its center could pass near Socorro Island by the morning of November 27.

The system is expected to weaken to a storm strength over the next 48 hours, as its center passes south of the southern portion of the Baja California. In the next 3 days Sandra is forecast to dissipate to a remnant low over Mexico's mainland, according to NHC.

No coastal watches or warnings have been in effect so far, however, residents of the southern portions of the Baja California Peninsula are encouraged to monitor hurricane's progress, as portions of the area may require tropical storm or hurricane watches by the end of the day. Over the next 24 hour heavy rainfall could affect the states of Nayarit, Jalisco, Colima, Michoacan, Guerrero and the islands of the Revillagigedo Archipelago.
