Huge amounts of rainfall in under 2 hours left areas of Mexico City suffering severe flooding on 7th September. Some reports claim water levels reached 1.6 metres in Iztapalapa. As many as 3,7000 homes were flooded there. Mexico’s National Weather Service reported that the heavy rainfall was “historic” with more than 86 litres per square metre falling in the Valley of Mexico.
The worst affected areas also include Colonia Cuauhtemoc and Tláhuac. Police and firefighters have been carrying out rescues and evacuations. Several metro stations have been closed due to flooding. Some roads and bridges have also been closed to traffic.
Some local media reports are blaming poor or blocked drainage systems for making the flooding worse. However, the National Water Commission, Conagua (Comisión Nacional del Agua) claim that the floods would have been much worse if drainage systems had not been in place and that the floods would have lasted days rather than hours. A few days ago, head of the Federal District government, Miguel Angel Mancera, had announced an investment of 200 million pesos for the construction of water works, amongst other things, to help reduce the risks of flooding in Iztapalapa, Tláhuac, Venustiano Carranza and Xochimilco.
Mexico has seen heavy rainfall over the last few days, since it first began on 6th september. The rains are as a result of Tropical Cyclone Lorena, which passed along Mexico’s north west coast from 5th September.
In the north western state of Nayarit, Mexico, flash floods on 7th September in Huajicori resulted in the death of one person, with two others missing.
