Mexico news organization Azteca Noticias called it a “historical hailstorm”.
Pictures from Twitter are remarkable; parts of the low latitude city appear transformed into a winter wonderland in the dog days of August:

Hail is not uncommon in the Valley of Mexico, which includes Mexico City.
On Sunday, an area of low pressure at high altitudes generated the instability necessary for the vigorous, hail-producing storms.
