Winds Slowly Diminishing

| January 10, 2013 @ 10:44 pm

It has been a wild night of high winds across Central Alabama as a dying convective system triggered a gravity wave and wake low setup.

The result was widespread 40-50 mph sustained winds with some higher gusts. Winds just off the surface were roaring at near hurricane force. Luckily, we didn’t have any convection to bring those high winds to the ground.

But the 40-50 mph winds with frequent gusts above 60 mph did cause numerous reports of trees and power lines down. The result was scattered power outages.

Many trees fell on houses. Fortunately, we haven’t received any reports of injuries. There was significant damage to the roof of an apartment complex on Princeton Avenue in southwestern Birmingham.

The winds are slowly diminishing, but gusts in the 40-50 mph range could affect eastern sections of Alabama. Higher elevations could see higher gusts.


An interesting notes from Steve Jones at the Alabama Quake Center. He reports that the wind actually caused vibrations in the ground that were picked up by their seismographs.

“Thought you might be interested in what the passage of tonight’s gravity wave looked like at the AlabamaQuake seismic station here in Huntsville. It appears on the seismogram that there were THREE main pulses of winds in the wave’s passage thru Huntsville, with the first being at 8:27 pm, and the last at 9:09 pm, the seismic signature being created due to the pressure impact of the gusty winds on the surface of the local terrain and the trees rooted there; the ground’s vibrations are of course detected on the seismograph.”

Thanks Steve!

And thanks to our skywatchers tonight for their excellent reports!

Tomorrow will be showery but mild, with highs around 70F.
