yay! except if I have power I still have to telework...until the office loses power.

none did during the derecho but some of the city did. but in a case like this not sure underground stuff helps if everything goes down.

Residential power will go down before commercial customers in almost all cases. Also worth noting.... some commercial buildings have redundant power. This means there are fed off of two different points on the electrical grid and can switch between them utilizing a "tie switch". In that case, there is a higher likely hood of them maintaining power. Finally, some buildings (or portions of bldg.s) have 100% emergency back up power through the use of batteries (large rooms of them) and diesel generators with very large fuel tanks.

These types of electrical system are typically found in larger buildings and hi-rises.

Unfortunately, the main distribution (sub station) is often times located below grade (basement/sub basement). This can expose the equipment to water, which will usually find it's way to the lowest elevation within the building....point of no return.

Evidence of failure as result of poorly located distribution systems (below grade) was illustrated during Isabel. Numerous buildings @ Baltimore's Inner Harbor were rendered electrically inoperable as a result of flooding their internal substations.

Metro shutting down tomorrow.

http://www.wmata.com...?ReleaseID=5362

In light of updated forecast information from the National Weather Service projecting higher wind speeds, as well as the closure of Federal Government offices in the Washington area and the possibility of widespread commercial power outages, Metro has announced the following service changes for Monday, October 29, 2012:

  • The Metrorail system will be closed on Monday. Rail service on Sunday night will continue operate as scheduled until its normal closing time (midnight). No decision has yet been made on when Metrorail service will be restored after Monday.
  • All Metrobus service will be suspended as of the end of the service day on Sunday and remain suspended until further notice.
  • All MetroAccess service has been cancelled on Monday.

Metro service will only be restored when it is safe to do so. Following the storm, Metro personnel will need to perform a comprehensive damage assessment, including inspections of track, bridges, aerial structures, stations and facilities. Service restoration also will be contingent on adequate commercial power to support operations and repair of any storm-related damage.

Customers are encouraged to
for information regarding restoration of service as information is known.

Just got a call from the boss that the office is closed tomorrow. Wife's work is closed, too, so we'll ride it out with the pup tomorrow and hope for the best.

Wish my boss would make the call, otherwise I'm up early to "work" from home

many school districts here are closed, but neither my wife or my work have closed, though i'm sure they will let her out early. i highly doubt my work will close.

I'm now off tomorrow but my wife, a nurse, is not. And when she goes to work I have a feeling I won't see her again until Wed. Would be the first time since 09-10 she's been required to stay at the hospital.

No change from what happened all day today. Little sustained winds and gusts in the teens. The band that's coming over the bay might help to pick those sustained winds up.

Hasn't been windy here for the most part. Just now getting some gusts to close to 30. Was mostly calm until about 4 PM.
