A violent early season blizzard raked Minnesota and the Dakotas. Winds
gusted to 70 mph at Yankton SD, and snow drifts 10 to 15 feet high were
reported in northwest Iowa and southeast South Dakota. Saint Paul MN
reported a barometric pressure of 28.65 inches on the 16th. Railroads were
blocked by drifts of snow which remained throughout the severe winter to
follow. Gales did extensive damage to ship on the Great Lakes. (15th-16th)

Hurricane Hazel struck the Carolina coastline. The hurricane demolished
every pier along a 170 mile stretch from Myrtle Beach SC to Cedar Island
NC, and obliterated entire lines of beach homes. Hurricane Hazel also
destroyed 1500 homes as it moved inland with seventeen foot tides. Winds
between Myrtle Beach SC and Cape Fear NC gusted to 150 mph. Hurricane Hazel
caused 163 million dollars damage, and claimed the lives of 98 persons.
(David Ludlum) (The Weather Channel)
Iowa experienced its worst late season tornado of record. In just one
minute a twister tore through the town of Belmond leveling 75 percent of
the businesses, and 100 homes, causing more than eleven million dollars
damage. (The Weather Channel)
Unseasonably cold weather continued in the eastern U.S., with thirteen
cities reporting record low temperatures for the date. The low of 34
degrees at Montgomery AL was their coldest reading of record for so early

City IL. (Storm Data) (The National Weather Summary)

when their vehicle was blown off the Galveston seawall into the pounding
surf. Total damage along the Upper Texas Coast was estimated at fifteen
million dollars. Thunderstorms produced severe weather in Lower Michigan
during the late morning. Two persons were injured when a tree fell on their
camper at the Traverse City State park. While strong northerly winds
ushered much colder air into the central U.S., unseasonably warm weather
continued in the south central and eastern U.S. The afternoon high of 82
degrees at Bluefield WV was a record for October. (The National Weather
