You’ve seen movies and cartoons, right? Ever watch a forlorn character with a single
rain cloud over his or her (its?) head, drowning them in a mini-storm? While this is
quite amusing, it is also true. On June 14, 1878, the village of Weston near Bath,
England, was the victim of point precipitation, a highly localized downpour that occurs
when storm clouds saturated with water dump all their moisture on one location. Seeing
only a light rain falling, none of the residents expected a flood. But water soon crashed
down the main street in four-foot-high waves, damaging houses and moving large stones.
Apparently, the localized rainfall had focused over a nearby hill, with the rainfall
running down into the town.
