07/02/12 70 W - + 2 - 5 Derecho


Defined by Wikipedia as "a widespread and long-lived, violent convectively induced straight-line windstorm that is associated with a fast-moving band of severe thunderstorms in the form of a squall line usually taking the form of a bow echo." Here's a timelapse of the storm system that produced the "super derecho" that struck the DC area on Friday, and that still has millions without power.
 





Mike, in this storm the Derecho arrived about 15 minutes prior to the actual line of thunderstorms and presented itself suddenly as a wall of wind. it actually went from dead calm to 80 mph winds in about 2 seconds. ( the nearest official weather station is in Galax and regestered the initial wind wall @ 81mph) The destruction especially to the power grid in West Virginia and South West Virginia reminds me of what North Carolina experienced during Hurricanes Floyd,Fran or Hugo. Friday night shortly after the storms had passed it was reported that 70% of West Virginia was without power. There was 1 Line of Duty Firefighter death a couple of counties over in Franklin County Virginia. A Volunteer Firefighter was responding to a call when a tree fell on top of his vehicle. He died this morning.

Wait, I thought only 30% of West Virgina had power to begin with.

No, you’re confused with teeth.

And your foreign-language lesson for today is:

In Spanish, “derecho” means “right”.

There is nothing “right” about what happened from this storm. Oddly enough, though, they played the Congressional Tournament even without power in the buildings or a gallery. Hm.

My limited understanding of the word’s etymology is this, found on the web: As an adverb, derecho typically means “straight ahead” or “in a straight line” as in anduvieron derecho, they walked straight ahead.
