Tropical Depression Twelve-E was a tropical cyclone that formed on October 12, 2011 and dissipated on October 12, 2011. As soon as advisories began, warnings were issued. The storm began as an invest south of the Gulf of Tehuantepec. The depression became post-tropical shortly after landfall late on October 12.

On October 13, the NHC noted the possibility of the remnants regenerating in the Caribbean Sea.

Meteorological history

Early on October 7, an area of disturbed weather formed a few hundred miles south of the Mexico coast. The disturbance quickly became more organized and two days later, the National Hurricane Center (NHC) noted that the low would likely deepen into a tropical depression because its atmospheric circulation had became more defined. However, thunderstorm activity diminished greatly near the center, with what little activity there was left displaced to the east due to heavy amounts of wind shear. On October 12, the system was finally declared a tropical depression. Twelve-E made lanfall in South-Western Mexico, and caused landslides and flooding in the country, as well as in Nicaragua, Guatemala and El Salvador. Guatemala was hit hardest, with a confirmed 13 dead. A total of 18 people died as a result of Twelve-E, with four in Nicargua and one in El Salvador. Damage is unknown as of October 13.

Preparations and impact

Upon the formation of a tropical cyclone, a tropical storm warning was issued for areas from Barra De Tonala to the Guatemala–Mexico border. The depression dropped intense precipitation over large parts of Central America, with many areas still receiving heavy rains. In Guatemala, extensive flooding and multiple landslides caused heavy damage to roads, cutting them off to traffic. The profuse rainwater filled up rivers, causing them to overflow and exacerbating the flooding. According to preliminary reports, heavy downpours caused extensive infrastructural damage and the collapse of six bridges in Nicaragua. Several telephone and electricity poles were downed, disrupting the services to customers. Storm-related incidents caused the deaths of four people and affected at least 1,622 others to some degree. Similar impact was reported in El Salvador, where up to 1,805 residents sought shelter in schools, churches and public centers. At least 10 rivers burst their banks due to the flooding rains, while up to 75 mudslides inflicted damage to roads. Overall, 18 were killed, 13 of which in Guatemala. Four died in Nicaragua, and 1 died in El Salvador.
