Tropical Storm Olga in Oct 2019 wrecked shite in N. MS and Tennessee last fall. Major power outages across the region and a cell tower blown down.


We were without power for 2 days and had 3-4 houses in the neighborhood with trees on them after Olga in Mandeville.

You don’t remember surprise 60-70mph winds last year?

GFS shift was about 30 miles east from LA/MS line to about Long Beach / Gulfport

Pressure drop at landfall from 994 to 977 mb.

That is very significant this late in the game, but another 6 hours will tell if it is a trend.

Outflow continues to improve and even encroach north a little as convection fires closer to center.

Winds
Post-tropical cyclone Olga produced strong and damaging winds over an approximately 300 n mi wide swath of the southern United States, including parts of Louisiana, Mississippi, and Tennessee. The highest wind observation over land was recorded at the LSU Coastal Studies Institute in Baton Rouge, Louisiana, where sustained winds of 48 kt and a gust of 62 kt were reported on 26 September 2019. Wind gusts as high as 63 kt were reported at Mandeville, Louisiana. A wind gust to 64 kt was reported near Ripley, Mississippi. Wind gusts of 40–50 kt were widespread across the above three states.

Was this the one that hit us around the Auburn game? That little storm packed a punch in my area.

I remember that! I live in Old Mandeville. That sucked!!!! So many trees on houses, power lines, and roads. It was nasty trying to sleep for 2 days in the heat.

Yes it was the same day as the Auburn game. My power was out for most of Saturday afternoon.

All that convection along the panhandle and southern Georgia worked to push the shearing ULL back this afternoon. Really noticed it backing away an hour or two ago.

Always hard to tell just looking at satellite but presentation definitely improved fast this afternoon.

I get confused with all these updates...it has been trending west now all of a sudden it jumped back East and stronger? Is this just one model predicting this right now?

18z ICON stronger and east. Maybe the HMON pulls the trick here since it was the 1st to pickup on this trend. Need to see the models hold because they could very well shift back at 00z.

It's a model showing it.

There has been a trend on ensemble products showing a stronger system turning north earlier and ending up east. It does make some sense why it'd do that.

It jogged back east over west st. Tammany but I don’t know about it getting stronger though wind wise.

EDIT: Nevermind. Just saw post afterwards talking about the other models. My bad, dawg.

When y’all are saying it looks better.... does that mean it looks stronger? Or it looks better like it’s weakening and better for our outcome?
