High Winds & Prolonged Rainfall in Northeast Ohio – October 29-30, 2012 – Part 2

Posted by in Weather Events | October 31, 2012

On-going high winds and prolonged rainfall in Northeast Ohio finally came to an end on the afternoon of October 30 after beginning late on the afternoon of October 29, 2012.   Local television and radio news media have reported damage from storms throughout Northeast Ohio.  Winds up to 46 MPH were recorded at Hopkins International Airport with gusts up to 68 MPH.  Both were out of the north northwest.  Maximum winds at Burke Lakefront Airport were measured at 46 MPH with gusts to 67 MPH, October 29, 2012.  Peak winds and gust measured at other weather stations were reported as follows:

Location                                                                        Peak Wind/Peak Gust in MPH (Direction)

Lakefront East of Downtown Cleveland                           N/M               68  (N)

MacIntosh Farms, Broadview Hts                                    18 (SW)         27 MPH  (Sheltered from North)

Mill Stream Run, Strongsville                                           33 (NNW)    38 (NNW)

I-77 &I-480, Independence                                             32 (N)            55 (NNW)

Westlake                                                                           17 (WNW)     31 (WNW)

North Royalton (on the hill)                                               35 (NNW)      67 (NNW)

For windspeeds in your area go to Weather Underground and search for your area, find the close weather stations and review the data for the week of October 28, 2012.  Note that some weather stations may have lower values as the wind meter is reported to be shielded  for winds from a particular direction.

There have been numerous reports and verified observations of downed trees, damaged trim to dwellings, power outages, and leaks at plugged roof drains and poorly flashed walls and windows on the north sides of buildings.  The tree and trim damages observed appear to be consistent with damages described in the Beaufort Scale for the wind and gust speeds recorded.  Fallen trees were generally spotted by this Writer on properties at the higher elevations (up on a hill) although some damage was observed at lower elevations.

This Writer observed that the downed trees were generally large pine trees although some deciduous trees were observed to be fallen.  All the trees observed had a relatively shallow root system.  The uprooting of some trees was probably assisted by prolonged rainfall softening the soil just prior to the high winds.  All the fallen trees were observed to have fallen generally north to south.

So now I would like to know, “Where are those ‘I Survived Superstorm Sandy!’ t-shirts?”

The next article will discuss the terms “peak wind” and “gusts.”  What is the difference?

(Please note that the fallen tree and dwelling above were seen while driving and reviewing damages in the area.  We did not provide any services for this dwelling.)
