CLEVELAND - According to the Cleveland National Weather Service, 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.
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). 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. Waves 25 to 30 feet high hit the break wall along the East Shoreway of Interstate 90, causing big head aches for motorists.
At 68 mph wind gust was recorded at Cleveland Hopkins Airport at 11:25pm on October 29th. A 67 mph wind gust blew threw Burke Lakefront Airport at 9:32pm that evening. A few hours later (12:25 am, October 30th), a wind gust of 49 mph was measured at the Akron/Canton Regional Airport. Mansfield measured a gust of 46 mph at 2:40 am, October 30th.
Rainfall totals were impressive as well! Prior to the arrival of Hurricane Sandy on the east coast, a storm 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). That rainfall, combined with the rains from the remnants of Sandy added up to some impressive amounts:
*Rainfall from Friday, 10/26 thru the next Thursday, 11/1:
CLEVELAND HOPKINS AIRPORT: 7.29 inches
AKRON/CANTON REGIONAL AIRPORT: 3.63 inches
MANSFIELD LAHM AIRPORT: 3.89 inches
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. 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.
