Late on October 6, a low pressure area formed several hundred miles south of the Mexican coast. The disturbance quickly became more organized and two days later, the NationalHurricane Center remarked that the low would likely strengthen into a tropical depression. However, thunderstorm activity diminished greatly near the center of circulation, with what little shower activity there was left displaced to the east due to high wind shear. On October 12, the system was finally declared a tropical depression. Although the depression was initially forecast to briefly reach tropical storm status, this did not occur; instead, it remained a large monsoon-like system with the strongest winds well removed from the center. Shortly thereafter, the depression moved ashore between Salina Cruz and Arriaga. Deep convection decreased after landfall and it dissipated within 24 hours after formation, early on October 13. But the storm's remnants continued to effect Central America, until late on October 13, when the remnants of Twelve-E were completely absorbed by a monsoon trough, directly to the remnant's east. The monsoon then developed into a strong upper-level low, and left Central America, and the storm began moving northeastward, while slowly strengthening.
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 24 hours, rainfall totals of more than 12 in were recorded 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. It affected at least 81 of the country's 333 municipalities, and about 340 homes sustained damage. Authorities confirmed the deaths of at least twenty three people, and there were up to 30,000 storm victims in the country. 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 service to customers. Storm-related incidents caused the deaths of at least five people and affected around 3,000 others to some degree. Similar impact was reported in El Salvador, where over 15.7 in of rain fell in several locations. At the risk of flooding, The maximum precipitation was in Huizucar, with 1513 mm, this being the highest cumulative rainfall for the country, up to 4,300 residents sought shelter in schools, churches and public centers. At least 21 rivers burst their banks due to the flooding rains, while numerous mudslides inflicted damage to roads. Heavy damage also occurred to crop, particularly in coffee, beans, and maize plantains. Overall, at least 24 people were killed when the storm damaged their residences. Elsewhere in Costa Rica, landslides and flooding damaged property and roads, but there were no fatalities in the country. In Honduras at least 9 people were killed and thousands evacuated.
