A long-lived and intense thunderstorm dumped hail that ended up being measured in feet in some parts of Mexico City Sunday afternoon and evening.
City tunnels and roadways became impassable in some locations and emergency workers were forced into action to free vehicles and open roads. Heavy equipment was needed to clean up the hail, similar to the clean-up efforts needed after a blizzard.

According to AccuWeather Meteorologist Mark Paquette, storms of this nature are not uncommon for Mexico City around this time of year.
"It's hail season for them," he said.
Mexico City sits at an elevation of roughly 7,000 feet which creates conditions where intense storms can barrel through the city, dropping heavy rains and even hail. Paquette likened the city to Denver, Colorado, which has a lower elevation but a similar setup in the late summer that allows powerful storms capable of spawning hail to form.
Unique to Sunday's storms was the extreme amount of hail that pounded the area. There were reports of hail stacking to the point where plows had to shovel the roads in efforts to make them clear.

In addition to the hail, torrential rain caused flash flooding adding to the travel woes. Storms hit other regions of Mexico as well as Loreto faced heavy storms that brought intense rain.
