People in Guadalajara, Mexico, woke up on Sunday to a thick blanket of ice over areas of their city, after a freak hail storm that damaged houses and left cars partially buried.

This is particularly strange because it’s the middle of summer. In the past month, temperatures most days have hit 90 degrees Fahrenheit or over.

Authorities say more than 450 homes were affected by the heavy hail, including some where the ice pushed through doors and windows, according to the local El Informador newspaper.

Guadalajara’s mayor, Ismael del Toro, told the newspaper that 10 people had been treated for symptoms of hypothermia.

The Mexican army and local authorities were deployed to use heavy machinery to dig out the city of nearly 1.5 million people, which is among the most populous in Mexico.
