Hurricane Ingrid lost intensity and was downgraded to a tropical storm before making landfall Monday near La Pesca, a town on Mexico's Gulf coast, weather forecasters said.
The storm was located about 40 kilometers (25 miles) from La Pesca and had maximum sustained winds of 95 kph (60 mph) at 1500 GMT, the U.S. National Hurricane Center, or NHC, said.
Ingrid is moving west-northwest at 13 kph (8 mph), the NHC said.
The Mexican government has discontinued the tropical storm warning south of La Cruz, but it remains in effect from La Cruz north to the San Fernando River.
The storm is expected to move inland and become a tropical depression later in the day, dissipating on Tuesday.
Ingrid, which was the second hurricane of the 2013 Atlantic season, could create dangerous conditions as it moves inland.
"Rains are likely to result in life-threatening flash floods and mudslides," the NHC said.
Tropical Storm Manuel, a system that affected Mexico's Pacific region over the weekend, has broken up.
"Satellite images and surface observations indicate that Manuel has dissipated over west-central Mexico," the NHC said.
The storm's remnants are expected to produce heavy rains in sections of the southern state of Guerrero and the western state of Michoacan, forecasters said.
Ingrid and Manuel killed at least 22 people in Mexico over the weekend, the Government Secretariat said Monday.
Fifteen people died in Guerrero, three in Hidalgo, three in Puebla and one in Oaxaca, the secretariat said.
About 238,000 people have been affected in Guerrero, located on Mexico's Pacific coast, by Manuel, national emergency management office chief Luis Felipe Puente said.
About 1 million people have been affected by the simultaneous storms, Puente said.
The two storms affected two-thirds of Mexico's territory over the past few days, Government Secretary Miguel Angel Osorio said. EFE
