Tropical Storm John formed quickly off the coast of southwestern Mexico around the same time as Ileana, which is just east of John. Infrared data from NASA's Aqua satellite provided forecasters with temperature data that showed the cloud top temperatures in John had cooled indicating the storm was strengthening.
John formed as a tropical depression on Sunday, Aug. 5 about 320 miles (515 km) south-southwest of Manzanillo, Mexico.
Tropical Storm Ileana formed quickly close to the coast of southwestern Mexico around the same time as John, which is just located west of Ileana. Infrared data from NASA's Aqua satellite provided forecasters with temperature data that showed the storm was strengthening as cloud top temperatures in Ileana had cooled.
Ileana formed as a tropical depression on Saturday, Aug. 4, south of the Gulf of Tehuantepec and about 250 miles (400 km) south-southeast of Puerto Angel, Mexico.
