context_page_description: Hurricane Pauline was one of the deadliest Pacific hurricanes to make landfall in Mexico. The sixteenth tropical storm, eighth hurricane, and seventh major hurricane of the 1997 Pacific hurricane season, Pauline developed out of a tropical wave from Africa on September 16, 1997, moving across South America and into the Pacific Ocean. On October 5, the depression intensified into a tropical storm early the next day and by October 7, Pauline had reached hurricane intensity. It initially moved eastward, then turned northwestward and quickly strengthened to reach peak winds of 135 mph. It paralleled the Mexican coastline a short distance offshore before weakening and making landfall near Puerto Angel, on October 9, and dissipated the next day.
  Hurricane Pauline produced torrential rainfall along the Mexican coastline, peaking at 32.62 inches in Puente Jula. Intense flooding and mudslides in some of the poorest areas of Mexico killed between 230 and 500 people, making it one of the deadliest Eastern Pacific storms in recorded history.
context_section_description: A tropical wave exited the coast of Africa on September 16. It traversed steadily westward, with the southern portion of the wave axis moving across northern South America. On September 26 the wave entered the eastern Pacific Ocean near Panama, and slowly organized. A weak low-level trough extended from the Caribbean Sea to south of Mexico, disrupting the normal flow of westward steering currents. On October 3, the tropical wave developed a distinct area of deep convection, and began to drift eastward to the south of Mexico. Two days later a low-level circulation formed, and midday on October 5 the system developed into Tropical Depression Eighteen-E while located about 250 miles (410 km) south-southwest of Huatulco in the state of Oaxaca.
  With an absence of vertical wind shear, the depression drifted just south of due east and steadily organized. The system developed banding features and a central dense overcast, and early on October 6 the depression intensified into a tropical storm and was named Pauline while located about 295 miles (475 km) south-southeast of Salina Cruz, Oaxaca. A strong high pressure system eroded the trough over southeastern Mexico, which turned Pauline to the northeast. An eye feature developed late on October 6, and early the next day Pauline intensified into a hurricane about 265 miles (425 km) southeast of Salina Cruz after turning to the north and northwest.
  Pauline rapidly intensified after becoming a hurricane with favorable conditions for continued development, and 18 hours after becoming a hurricane it attained a peak intensity of 135 mph (215 km/h). The winds of the hurricane weakened slightly to 115 mph (185 km/h), but on October 8 Pauline re-strengthened to reach winds of 135 mph (215 km/h) a short distance off the coast of Mexico. The hurricane turned more to the west-northwest while paralleling the southern coast of Oaxaca, and Pauline quickly weakened due to interaction with the mountainous terrain before landfall near Puerto Ángel as a 110 mph (175 km/h) hurricane early on October 9. The tropical cyclone continued to weaken as it paralleled the coast a short distance inland. On October 10, Pauline dissipated over the state of Jalisco.
