Authorities in central Mexico were on alert early Saturday for possible mudslides and flooding as the remnants of Hurricane Karl pushed inland hours after the storm swept onto the Gulf coast and killed two people. Out in the Atlantic, meanwhile, Hurricane Igor strengthened into a Category 2 storm and became better organized on a track to approach Bermuda late Sunday. Karl, which caused widespread property damage as a hurricane in the port city of Veracruz, weakened to a tropical depression Friday night and was expected to quickly dissipate over the mountains, the U.S. National Hurricane Center in Miami said. A landslide buried a house in the town of Nexticapan, killing a 61-year-old woman and a 2-year-old girl and injuring two other people, said Aru Becerra, a spokeswoman for Civil Protection in Puebla, a state bordering the Mexican capital. Authorities across central Mexico prepared for possible flash floods and mudslides. Mexico City officials put hospitals on alert and sent workers to evaluate hillside neighborhoods and flood-risk zones. Officials in the capital and nearby Cuernavaca put crews on alert and designated schools and other buildings as possible shelters. The Mexican capital was in a state of «blue alert,» meaning the risk was considered moderate, city Civil Protection Secretary Elias Moreno said. The storm had sustained winds of 115 mph (185 kph) when it hit land at midday about 10 miles (15 kilometers) northwest of Veracruz. Its winds were down to 35 mph (55 kph) by nightfall, the Associated Press reported.
