context_page_description: The effects of Hurricane Isabel in Pennsylvania were primarily related to tropical storm force winds across much of the state. Hurricane Isabel formed from a tropical wave on September 6, 2003 in the tropical Atlantic Ocean. It moved northwestward, and within an environment of light wind shear and warm waters it steadily strengthened to reach peak winds of 165 mph on September 11. After fluctuating in intensity for four days, Isabel gradually weakened and made landfall on the Outer Banks of North Carolina with winds of 105 mph on September 18. It quickly weakened over land and became extratropical over western Pennsylvania the next day.
  On September 19, Tropical Storm Isabel passed through southwestern Pennsylvania, though its large circulation produced tropical storm force winds throughout much of the state. The passage of Hurricane Isabel resulted in $160 million in damage and two indirect deaths in Pennsylvania. One person suffered from carbon monoxide poisoning, believed to be caused due to improperly ventilated generators in an area affected by the power outages.

Hurricane Isabel formed from a tropical wave on September 6, 2003 in the tropical Atlantic Ocean. It moved northwestward, and within an environment of light wind shear and warm waters it steadily strengthened to reach peak winds of 165 mph (265 km/h) on September 11. After fluctuating in intensity for four days, Isabel gradually weakened and made landfall on the Outer Banks of North Carolina with winds of 105 mph (165 km/h) on September 18. It quickly weakened over land and became extratropical over western Pennsylvania the next day.
  On September 19, Tropical Storm Isabel passed through southwestern Pennsylvania, though its large circulation produced tropical storm force winds throughout much of the state. The passage of Hurricane Isabel resulted in $160 million in damage (2003 USD, $187 million 2008 USD) and two indirect deaths in Pennsylvania. One person suffered from carbon monoxide poisoning, believed to be caused due to improperly ventilated generators in an area affected by the power outages. Moderate winds left about 1.4 million customers without power across the state as a result of trees falling into power lines, with dozens of houses and cars damaged by the trees.
