Freak flooding in Guadalajara after a massive hail storm. Pictures on BBC:

Six suburbs in the Mexican city of Guadalajara were carpeted in a thick layer of ice after a heavy hailstorm. The ice was up to 1.5m (5ft) thick in places, half-burying vehicles.

[...] Hailstorms form when warm, moist air from the surface rises upwards forming showers and storms. Temperatures higher up, even in summer, can get well below 0C and so ice crystals form along with something called "supercooled water" which then grows into pellets of ice.

In severe thunderstorms, air can rise rapidly and is able to hold up these hailstones and allow them to expand in size. Eventually they get too heavy and fall to the ground.

In warmer parts of the year, such as in Guadalajara which has maximum temperatures of around 31-32C [(87-90 °F)] in June, more moisture is available, contributing to the formation of hailstorms.

Temperatures this month have been higher than normal with Torreon, to the north of Guadalajara, reaching highs of 37C [(99 °F)].

Hm, I wonder if somebody is going to mention anthropogenic warming with this?

    I didn't think of Steely Dan - I heard James Taylor singing instead.

    Just yesterday morning they let me know you were gone
    Susanne the plans they made put an end to you
    I walked out this morning and I wrote down this song
    I just cant remember who to send it to
