Heavy rains produced by Cyclone Yaku cause severe flooding and landslides in western Ecuador

Heavy rain caused by Cyclone Yaku produced severe flooding and landslides in western Ecuador, resulting in the deaths of at least 3 people. The worst affected was Chone Canton in Manabí Province. The National Meteorology and Hydrology Service of Peru (Senamhi) described Yaku as an unusual and unorganized tropical cyclone.

The Risk Management Secretariat of Ecuador (SGR) reported that three people lost their lives due to the extreme weather, with two fatalities caused by a landslide and one due to the overflow of the Mosquito River. Furthermore, approximately 2 000 people have been affected, and one house has been destroyed.

According to El Comercio, 90% of downtown Chone was flooded on March 7. In addition, damaged homes and crops were reported in nearby rural areas, forcing authorities to declare a state of emergency.

Two additional rivers, Garrapata and Chone, have broken their banks, causing further damage and danger to residents in the area.

National authorities have taken swift action to provide assistance and humanitarian aid to those affected. However, with the floods causing the evacuation of the Chone Basic Hospital, the situation remains challenging.

Despite the efforts made by the authorities, further rainfall is forecast for March 9. However, there is hope that the situation may improve by March 10, with drier conditions expected across the affected Manabí Province.

The National Meteorology and Hydrology Service of Peru (Senamhi) has reported an unusual “unorganized tropical cyclone” off the north and central coast of Peru earlier this week.

This clockwise low pressure system is also responsible for the extreme rainfall in Tumbes, Piura, and Lambayeque, as well as the anticipated intensification of rains in La Libertad, Lima, and Ancash in the coming days.

Senamhi specialists identified the formation of this system at the end of February and have been closely monitoring its progress and potential impacts.

Cyclone Yaku, as it is known, is associated with the warming of the sea surface temperature and the second band of the Intertropical Convergence Zone (ITCZ).
