Mammatus clouds over North Delta (Scott Rd. @ 64th Av)
These are beautiful clouds, but they are indicative of a major/severe thunderstorm nearby. Taken on October 26th, 2009, at 5:15pm. The storm missed all of Metro Vancouver luckily, but to our south Bellingham/Mount Vernon got hammered. These cloud are so rare to see in Vancouver, that I've only ever seen them 3 times including this one in my whole life. The others were in July of 1997, where Metro Vancouver was put under a severe thunderstorm warning for probably the first and only time in it's history, and May of 2002.
