Mexican Interior Ministry declared a state of emergency in six cities of the eastern state of Veracruz on Thursday after heavy rains slashed eastern Mexico.
In a press statement, the ministry said the General Coordination for Civil Protection will provide immediate aid to Zapata, Ixhuaxan de los Reyes, Naranjos Amatlan, Panuco, Pueblo Viejo and Tlaltetela.
Fifteen of the 31 states of Mexico were on maximum alert for downpours after seven people were killed on Wednesday by landslides and floods.
Adverse weather has affected half of Mexico and has left many families without communication in the states of Chiapas, Tabasco and Veracruz, where the government has already launched relief efforts.
Four rivers in Veracruz, the hardest-hit state, have overflowed and floods have left about 10,000 families homeless in 111 municipalities.
The Interior Ministry has instructed the Fund of Natural Disasters (Fonden) to deliver food, medicine and shelters to people in the flooded regions.
