The "White Hurricane" was the result of two separate weather systems that merged into one huge system that covered the entire eastern half of the country. In some respects the evolution of this system has some similarities to the evolution of Superstorm Sandy last year. On November 7-8 a strong low was moving across the northern U.S. trailing a strong Arctic cold front. This system primarily impacted Lakes Superior and Michigan, producing storm force winds, heavy snow, and high waves. Several large ships were damaged or run aground as this system moved across the lakes. In the meantime, weak low was moving northeast out of the Gulf states and over the southeastern United States on November 8.

Over the next 24 hours the low over the Great Lakes phased, or merged, with the low in the southeast, resulting in explosive and rapid intensification, what we call a meteorological "bomb". On the morning of November 9, 1913 the intense storm was centered over Washington DC.

Instead of moving out to sea, the storm turned to the north northwest. The circulation of the storm was tapping the cold Arctic air on it's west side and feeding off abundant moisture from the Atlantic. By the morning of November 10 the center of the storm was located over Lake Ontario.
Winds associated with the storm were estimated to be at hurricane force (74 mph or greater) for a period from 10 to 20 hours over the Great Lakes. Survivors reported wind gusts to 90 mph on Lake Huron on November 9. Winds on Lake Erie were 50 to 70 mph with gust to 85 mph. The ferocious winds for a prolonged period of time over he lakes produced waves up to 35 feet occurring as often as every three minutes. Ships of the day were not capable of withstanding these extreme conditions, especially with whiteout conditions and buildup of ice on the ships . A total of 12 ships were lost and 33 others were damaged during the four-day period. Several ships lost during the storm were never located.

Snowfall blanketed much of the Great Lakes region from this storm. Heavy snow fell across eastern Ohio, West Virginia, and western Pennsylvania with moderate snowfall extending west into Michigan. The Great Lakes were still relatively warm in early November, and the frigid Arctic air streaming over the warm waters resulted in heavy lake enhanced snow. Record snowfall occurred in Cleveland, OH with 17.4 inches falling in a 24 hour period and a three day total of 22.2 inches.
