Hurricane Sandra (22E) over Mexico

At 4 p.m. EST (2100 UTC) on Nov. 23, Tropical Depression Twenty-Two-E was born near latitude 10.8 north, longitude 102.9 west. Twelve hours later it strengthened into a late-season tropical storm. By the early morning hours of November 24, Tropical Storm Sandra became the 18th named storm of the Eastern Pacific hurricane season and on November 25 Sandra became a strong hurricane taking aim on Mexico’s western coast.

Hurricane Sandra’s winds peaked on November 26 with maximum sustained winds near 143 mph (231 km/h), making it a Category 4 storm on the Saffir-Simpson Hurricane Wind Scale. This was the latest Category 4 storm on record for either the eastern Pacific or Atlantic basins. The previous late record was set by Hurricane Kenneth which formed on November 22, 2011.

Fortunately, the storm began to interact with unfavorable conditions and began to dissipate rapidly as it approached Mexico. By mid-day on November 28 Sandra became a tropical depression and the National Hurricane Center (NHC) issued its last advisory on the system on November 29. Although Sandra and her remnants brought rain to the region, Mexico was spared a landfall.

The Moderate Resolution Imaging Spectroradiometer (MODIS) aboard NASA’s Terra satellite captured this true-color image on November 27, 2015. The center of the weakening storm is located southeast of Cabo San Lucas on the Baja California peninsula and to the west of the Isla Maria Madre and Isla Maria Magdalena. Wind shear is pushing most of the rain to the east of center, and rain bands reach over much of southwest Mexico and part of Baja California.
