data from a Reconnaissance aircraft flight into the storm found a minimum central pressure of , as the storm was drifting to the northeast at around near the western edge of a large-scale east–west ridge axis. The apparent eye became cloud-filled shortly thereafter, and a slight increase in temperature was discovered near the center. Despite this, upper-level outflow was favorable, leading to predictions of slight intensification. Shortly thereafter, Madeline attained peak winds of about southwest of San Blas, Nayarit. The hurricane maintained peak winds for about 18 hours while curving again to the northwest. With evidence of southern wind shear, only a small area of deep thunderstorm activity existed on October 19, and the system began to appear ill-defined of satellite imagery. The hurricane quickly weakened into a tropical storm, and by later that day, the storm became void of convection due to strong wind shear. On October 19, the storm was downgraded to a tropical depression, leaving just a swirl of low clouds midway between the southern tip of Baja California and mainland Mexico. By 0600 UTC on October 20, the remnants of Madeline had completely dissipated. Preparations and impact In anticipation of Madeline, the government of Mexico issued a tropical storm warning for the Baja California Peninsula southward from La Paz, and a hurricane warning from San Patricio, Jalisco to El Dorado, Sinaloa, including the Islas Marías. The storm was initially forecast to move ashore near Mazatlán, prompting officials to close the city's port. President Ernesto Zedillo advised potentially affected residents to stay indoors or seek refuge in shelters. Also, the threat of the hurricane canceled a fishing expedition in the Gulf of California due to rough surf. The expedition was to provide a new aquarium in downtown Denver, Colorado with about 8,500 fish. Mexican authorities deployed 2,000 soldiers in remote areas of the Pacific coast state of Sinaloa to prepare for the hurricane. Several thousand residents and tourists at the resorts of Puerto Vallarta and Mazatlan were put on standby to evacuate their homes. Authorities along the coast in the state of Nayarit went house to house, advising people about the oncoming storm. In addition, ships from Salina Cruz to Acapulco were advised to stay in port. Although Madeline never crossed the coast, numerous rainbands affected the Mexican coast, dropping up to . Despite this, no damage or fatalities were reported in Mexico. After the storm had
