WeatherUnderground shows the potential wind speeds from Hurricane Irene.
Starting from the hurricane icon off the coast of Ocean City, those in the closest rings will have hurricane force winds. As you’ll note they are stronger on the right side than they are on the left. What I’m talking about below is for the circle WHEN the hurricane is in the position in Ocean City area, not when it is moving up to that area.
The next ring is tropical storm winds > 50 knots per hour but less than 73 knots. This includes parts of the Eastern shore just about to Cambridge.
The next ring, the largest ring, is tropical storm winds > 34 knots and < 50 knots. This includes basically everyone East of Bethesda, East of Woodbridge, East of the Mixing Bowl.
Please note the storm will be moving, which is why toward the bottom you see the remnants of other circles drawn. There you will see a large swath of hurricane strength wind to the right of the storm when it the hurricane icon (not seen) is south of Newport News. In this ‘circle’ you’ll see hurricane strength winds extending over nearly the ENTIRE Eastern Shore.

During Isabel, we lost a few dozen roofing shingles along with having quite a bit of water flood into our house through the ceilings. All told I think it was about $10,000 in damage after FEMA and the insurance companies finished arguing. I also lost quite a bit of soil on my seawall, which spent hours underwater. The nearby towns of Chesapeake Beach and North Beach were heavily flooded, with 4 feet of water heading inland a few hundred yards and National Guard troops called out to control security. We were also without power for 7 days.
- The posts are normally 6 feet above sea level
So how will Irene stack up to this storm? It’s slower moving, stronger, but also further away than Isabel. The most similar track was that of Hurricane Floyd in 1999, which caused considerable rain and flooding along with some tropical storm level winds.
As you can see from the pictures, I’m not really worried about a storm surge taking my house. That would be basically a biblical level Tsunami to get up the 40 odd foot cliff to my actual house. I do anticipate my seawall getting another battering from this storm, which means I might need to rearrange the rocks (again) before the coming winter squalls.
The rain is going to be a big pain in that the soil is already pretty wet in the area. The super saturation along with the winds will likely result in a number of trees falling over in the forests just North of my property. I just have to hope they don’t come to rest on my roof. They are a shallow root trees and even a good thunderstorm takes out more than a few, dropping power lines in the process.
For much of the other areas around me, I anticipate some pretty heavy flooding in Southern Maryland mixed with near hurricane force winds. Tropical Storm winds that will hit the middle Bay will be annoying but many homes there are built with hurricanes in mind (we have hurricane struts in our roofing).
Still, I’m plenty nervous. This will be a very long weekend staring at computer screens and the weather.
