Sep 20, 2003
On September 18, 2003, Hurricane Isabel made landfall on the North Carolina Coast. Its wind field extended for hundreds of miles from the storm's center. As bad as it was across Maryland and Virginia, it could have been much worse. The air at the surface was relatively cool. Temperatures had been in the 60s during the day and the strongest winds came at night. Most areas saw wind gusts of 50 to 60 mph. However, wind sensors on building tops in and around DC recorded winds averaging 70 to 80 mph
