Remnants of Hurricane Sandy Impact
Northern OH and NW PA

Hurricane Sandy tracked up the east coast of the United States and merged with an upper level trough on October 29, 2012. Hurricane Sandy transitioned to a post-tropical cyclone and came onshore around 8 pm EDT in Southern New Jersey with an impressive central pressure of 946 mb or 27.94 inches. The post-tropical cyclone tracked west across Pennsylvania overnight on October 29 and brought damaging winds and prolonged rainfall to Northern Ohio.

The Visible Infrared Imaging Radiometer Suite (VIIRS) on the Suomi NPP satellite acquired this image of the storm around 3:35 am EDT on Oct 30th.

Impacts from High Winds

-------------- On Land --------------

tree damage from Erie Co. Numerous trees were downed all across northern Ohio, with the hardest hit areas from Lorain County through Lake County. To the left: a large pine tree fell in Erie Co. Below: Downed trees caused significant damage to property and power lines.
tree and powerline damage in Lorain Co.

Northerly winds were especially strong downwind of Lake Erie due to the un-obstructed flow and deeper mixing heights over the warm water. High winds impacted the lakeshore counties of northern Ohio.

The strong winds caused extensive tree damage with widespread power outages and even structural damage to some buildings. The Cleveland metro area was particularly hard hit with numerous school closures (some for multiple days).

Buoy 45005 Lake Erie

wave heights from 45005

Storm Force winds (50 knots) generated waves of 15 to 18 feet.

Waves reached as high as 14 feet from buoy 45005 located 16 NM northwest of Lorain (shown in the graph above).

Below are charts from (National Ocean Service) equipment at Cleveland that records water level and various meteorological data. The water level was nearly 3 feet above low water datum (a nautical reference mark). This was 1 to 2 feet above recent levels. Before and after the storm readings were just under 20 inches.

Prior to the arrival of Hurricane Sandy to the east coast, a continental (mid-latitude) weather system was making its way across the Midwest and Great Lakes. This brought rainfall to the local area on Friday night (10/27) and Saturday morning (10/28). Rainfall amounts ranged from 0.5 inches to 1.5 inches as shown by the images below of rainfall reports from our Cooperative Weather Observers.

24-hr rainfall ending 10/25 morning24-hr rainfall ending 10/26 morning24-hr rainfall ending 10/27 morning24-hr rainfall ending 10/28 morning

This system interacted with and absorbed the tropical system, Sandy, moving north just offshore of the east coast. By the time Sandy made landfall in NJ, it had lost its tropical characteristics and was considered post-tropical (or extra-tropical).

The cold front that had crossed the area on Friday night stalled just to our east and was re-invigorated by the developing hybrid storm. Additional rain fell Sunday and Sunday night (1.0"-1.5"). By Monday the precipitation shield from the merged system reached as far west as western Ohio.

24-hr rainfall ending 10/29 morning24-hr rainfall ending 10/30 morning

Rainfall from Monday and Monday night (8 AM EDT Mon - 8 AM EDT Tues): rainfall from this 24-hr period ranged from under a half inch in northwest OH to 1.5 to 3.5 inches across north central Ohio into northwest PA. On the outskirts of the precipitation shield late Monday night into Tuesday, snow fell from Findlay to Mansfield and Columbus. The Mansfield Airport reported 2.5 inches of snow.

The rainfall led to flooding along area rivers. The Cuyahoga River reached into major flood status. The Huron, Vermilion, Chagrin, and Black Rivers reached into minor and moderate flood status. Along the Cuyahoga River the worst flooding occurred in the Valley View area where many roads were blocked and basements inundated. With the winds forcing large waves on Lake Erie and a rise in water level along the southern shore, rivers were not draining as efficiently. The combination of lake-induced flooding and river flooding from rainfall resulted in flooding in the towns of Willoughby and Vermilion, where homes near the mouth of the rivers were inundated.

rainfall from 8am Mon-8amTue

Rain continued the remainder of the week as the influence of the low lingered. The center of the low reached western PA late Tuesday and then began to slowly pull away Wednesday onward. Precipitation is locally enhanced by Lake Erie and from upslope flow across the higher terrain of northeast Ohio.
