On the evening of 23 September, Hurricane John hit the southern coast state of Guerrero, Mexico. The category 3 hurricane then continued along the coast, causing flooding in different towns, including the tourist city of Acapulco.
Hurricane John brought four days of rain, the National Water Commission recorded rainfall of 1000 mm over 3 days, which caused flooding with water levels as high as 2 metres in neighbourhoods near rivers and streams. Many people were trapped in their homes due to flooding.
Emergency response teams in the resort city of Acapulco carried out rescue operations by boat, jet ski and helicopter, and residents waded through roads flooded up to waist height. At least 22 people have died, many due to mudslides that crushed houses.
