Hurricane Hurricane Barry (Gulf of Mexico)

[Kory]

Overwhelming under performance by Barry so far rain-wise. What a little upper level dry air will do.

They keep showing Mandeville’s lakefront on TWC. This happens every time there is a tropical system. Meanwhile my neighborhood is high and dry less than a mile away. Come to think of it, the streets are barely wet.

A few light sprinkles so far here; even a landfalling hurricane can't break the anti rain shield. Gonna have to start xeriscaping with cacti soon I guess.

Today might be the day where training bands set up. We've seen it already over Central LA into MS. A few tornadoes can't be ruled out.

The Alabama defensive line is holding. You'd think I'd posted in the wrong thread, but no.

Major flooding from Barry ongoing in Central and SW Louisiana.

That upper level low is helping pulling the moisture plume that Barry created up and over the same areas. Really curious where it goes, because it could keep training rain bands up for a while if it doesn't get on out of east texas.

Yep. Took a while but forecasts of 2+ feet of rain look to verify over southwest and central Louisiana. The media is already running with the story of Louisiana dodging the worst as people are being rescued from houses.

 

[Kory]

Storm surge forecasts underestimated Barry’s surge. 3-6 foot forecasts with actually 9+ foot readings.

Is there a local geographic feature there that may have amplified the surge? Seems like that might be an important question to answer for emergency preparedness there in the future.

Just wanted to include this local weather update from local channel 4 because it shows how HUGE (and, finally, well organized) TD "Barry" is now, and also gives rain totals in central Louisiana:

The bathymetry or the Gulf Coast, especially Mississippi and Louisiana, favor more amplified storm surges. But I’d think it’s more due to the fact the storm took forever to move in. Hurricane Issac in 2012 was the same. We had surges with Isaac that we’re well above the normal threshold for a strong category 1. It took almost a whole 24 hours to go from the Mouth of the Mississippi to Baton Rouge....a very slow mover.
