Tropical Major Hurricane Laura

"It's already beginning. Take note that these photos were taken in Golden Meadow and Leeville, Louisiana, well to the east of where Laura will actually make landfall. Also, this is already happening, even though Laura won't make landfall until late tonight. Sadly, what's shown in these photos pales in comparison to what's about to happen in southeast Texas and southwestern Louisiana. Photos shared by the Lafourche Parish Sheriff’s Office -Matthew"

That is insane and Laura is still 12 hours out. Prayers and thoughts for all those going to be affected by Laura. This goes well inland even into where I am at in TN.

I have a friend from New Orleans whose family intended to ride out Katrina, but changed their minds when a police officer insisted that my friend's mom write her social security # on her arm in sharpie while he watched when she was stopped at a road block headed back into the city the day before it hit, after doing an errand in Baton Rouge.

Good tactic by officer to bring home true impact
 
If that surge map is accurate, or even close, Lake Charles is gonna be in a world of hurt. I'm not familiar with the topography there and how that city is situated in relation to sea level, but a 15-20 ft surge coming up that river is going to put a lot of ground under water in a hurry.

Is there a reason the 12z models are initializing with pressure at 971mb?

Hour 6 still has higher pressure than what it is now

Resolution of the model. If you put the actual pressure at the single point the entire grid point however many km it is on the model would register at that pressure. That would create chaos within the model as you try to fill in the adjacent grid points with rapidly increasing pressures and the end solution would be a wonky mess. The model has to spread and raise the pressure to handle the physics correctly.

Its also why on many globals in the summer you see big areas of green across the south during the afternoon convection period but may only have a few scattered storms.
