Sparky Posted February 24, 2011 Share Posted February 24, 2011 i think it's fairly windy here, not as bad as this winter usually but it's not like we never get wind pretty much agree. Oct - Apr is pretty windy at times. The rest of the time it is rather tranquil going into summer which is nice! Link to comment Share on other sites More sharing options...
BethesdaWX Posted February 24, 2011 Share Posted February 24, 2011 When was the last time we had a windstorm without westerly winds? Isabel in 2003?...and it wasn't even that bad, yet everyone lost power. I'd bet 5 grand that if we were to see a day of HHW caliber winds out of the East, instead of the West, alot of us would be in the dark for several days. Wind direction can make a huge difference in tree damage. The trees around here are Shaped by the NW winds. Alot of that is due to the Exposure & Drop-off in the Land, but alot of it also is just the way the Mid-Atlantic Is. Put in a 70mph East wind, alot of trees may not do so well.

Are you seriously saying that Isabel wasn't that bad? I remember reading somewhere that winds peaked in our area at an 83mph gust. This plus extremely heavy rain (soft ground) made it bad for a reason. I remember walking to a friends house and watching whole branches (as the storm moved in) blow out of the trees and land on power lines. Seemed pretty bad to me. Put in a 70MPH west wind and NO trees will do well...reference the derecho in 2008.......... Link to comment Share on other sites More sharing options...

I lost power during the Day, and so did most of bethesda after midnight it was another story completely. Could have lost power for another reason. I know that Bethesda has a lot of odd lines (see the PEPCO criticism in the media recently) - they have a lot of feeders that cannot sustain a lot of usage or damage. What time did you lose power in that? We lost it while it was still light. Link to comment Share on other sites More sharing options...
BethesdaWX Posted February 24, 2011 Share Posted February 24, 2011 Speaking of Isabel, I think my point was the direction of the wind made things worse then they would have been, no power for 8 days is alot for 70mph gusts. I believe Silver Spring had an 83mph wind gust. I didn't have a rooftop weather station then, and it was pitch black when the Big Gusts hit, but it was scary for me, I was only 11 years old. I remember during the day, it was just "windy". Power went out around 1PM, and at that time, winds were 35mph at best. That is unacceptable.

You probably have a point with your comment about direction of wind - it definitely makes sense. But my point is 70mph in ANY direction will cause damage. Many people were out for 4-5 days (a few people were up to 7-8 days) during the 2008 derecho...those were west winds. Link to comment Share on other sites More sharing options...

I remember there were powerpoles snapped right in my nieghborhood (Glen Echo), which happened during the big overnight gusts. Since I was 11yrs old, I don't remember as well. I do know for a fact that we lost 3 large trees and our gutter+ siding was torn up. But 8 days without power? Are you kidding me? 7/25 had stronger winds, and similar damage, but that was 4 days, not 8. Link to comment Share on other sites More sharing options...

June 4, 2008 was one of the most memorable severe weather days of my lifetime so far. No damage here.............It obviously hit you alot harder than me.......kept power, highest gust was 41mph. It didn't meet severe qualifications here. I'm surprised 7/25 isn't tops for you.........my heart is still beating fast from that one! I knew it was coming, so I had my Vantago pro data streaming live to my laptop in case power was lost. The data streaming to the laptop: For 10 minutes.....winds gusted between 68-92mph, and never got below 50mph or so. 16 gusts over 75mph, highest was 92mph, also hit 87 85, 82, 81, 81, those are the highest ones I'm looking at now. ..... Computer software can also be purchased for the Vantage Pro2 specifically to stream and record. I'm thinking about putting my station on WXbug.

BethesdaWX Posted February 25, 2011 Share Posted February 25, 2011 Derecho definitely topped 7/25 for me. 7/25 was still intense though. The one thing about 7/25, the "intense" damage was very local. 500 yards away the damage was quite minimal. There was another corridor of "intense" damage near Whittier blvd and Walt Whitman HS, where entire White Pine rows were snapped off 1/2 way up. If you drive along river Rd tomorrow, and look at the Walt Whitman Field, you'll see pockets of Pine Trees that are snapped about 15 feet up. Pyle Road still had snapped trees everywhere in the woods next to it I drove into NW DC along military rd to 16th street, and it was like nothing happened. Drove back, then north, N potomac was hammered, then another break with no damage just SW of Rockville, before another area of heavy damage a bit further north, probably going right through Rockville, I'm sure they got hammered. FYI, I was only following River Rd, so I may have missed stuff in the nieghborhoods themeselves. Link to comment Share on other sites More sharing options...

Are you thinking a couple places top 60? maybe but it had hours and hours of 50 mph+ winds. those do damage regardless of fires. there were not a ton past 60 I guess tho. MOS has been advertising upper 20s/low 30s kts sustained. it looks like there's a window in there where 60+ is definitely possible. Link to comment Share on other sites More sharing options...
