SNINCR is a remark that can be placed in Meteorological Aerodrome Reports (METARs) and stands for "Snow Increasing Rapidly". For example, "SNINCR 2/8" indicates 2 inches of snow accumulated in the past hour with 8 inches total on the ground. See the end of section 12.7.1 of the "Federal Meteorological Handbook No. 1" for more information.

THE OTHER "PERFECT STORM"

The unnamed hurricane which occurred from the end of October to the start of November 1991, made famous in the movie "The Perfect Storm", is shown in this NOAA GOES-7 satellite image. But another storm is also raging. Look at the satellite image again. Notice the big swirl of clouds over Minnesota, Wisconsin, and Iowa on the upper-left edge of the image. Those clouds are a big snowstorm that storm became known as the Halloween Blizzard of 1991. From October 31 to November 3, the storm buried eastern Minnesota and adjacent sections of western Wisconsin with 24+ inches of snow. The heaviest snow fell along Interstate 35 from Minneapolis to Duluth and into the arrowhead of Minnesota. Duluth received 36.9 inches, the largest snowstorm on record for the city.
