Hurricane Sandy Likely to Damage Windows in High-Rise Buildings
Posted on October 28, 2012
Hurricane Sandy is a massive storm. Winds of tropical storm strength or greater currently stretch out for over 520 miles. Damage to windows in high-rises in the impacted major urban areas will be just one of the many impacts from the storm. It won't be a big of a problem as surge, flooding and power outages, but it will be add to the damage from Sandy and could open up buildings to potential water damage.
The high wind warnings for the New York City area from Hurricane Sandy calls for a long duration event - 6 am Monday to 6 pm Tuesday of strong winds sustained in the 35 to 55 mph, with gusts of 70 to 80 mph. Winds will be higher in high-rise buildings. A Wall Street Journal report says winds are expected to reach up to 90 mph in higher floors of skyscrapers in Manhattan. The National Weather Service indicates there is the possibility of broken windows due to flying debris.
