It is. But it keeps strengthening.

Yeah. Landfall was between the 48 and 72 hour positions. One of the experts can post the 60 hour position that they have access to that shows the pressure and location at landfall.

Gotcha.

I was looking at the 24 hour updates where it was 988 48hrs in and 988 72hrs in.

ETA: right before landfall & right after

Marco continues to weaken as the deep convection has been stripped
away from the center since this morning. An Air Force Reserve
Hurricane Hunter aircraft currently investigating the system has
reported peak 925 mb flight level winds of 38 kt. Although
there have been a few recent higher SFMR measurements that are due
to rain contamination, a recent ASCAT overpass revealed only
a small area of 30-35 kt winds.
Based on these data the initial
intensity is being lowered to 35 kt and a special advisory has been
issued to update the short-term intensity forecast and discontinue
warnings for the Gulf coast.

The showers and thunderstorms generating the tropical storm force
winds to the northeast of Marco's center are forecast by most
models to gradually dissipate through this evening.
Based on how
quickly the vortex has been spinning down and the anticipated
decrease of convection, it is reasonable to assume that sustained
tropical storm force winds will no longer reach the northern Gulf
coast. Therefore, all wind and surge warnings for the Gulf coast
associated with Marco have been discontinued.
Shortly after the
cyclone reaches the Gulf Coast later tonight it should degenerate to
a remnant low, with this low dissipating inland within a couple of
days. The latest intensity forecast was adjusted downward through 12
h, but remains the same as the previous NHC forecast thereafter.

Marco has been moving slowly all day, and an initial motion
estimate is now 320/5 kt. There is no change to the forecast track
reasoning. As the cyclone continues to weaken and degenerates to a
remnant low, a turn to the west-northwest is expected as the system
becomes steered in the low level flow. The latest forecast track
was adjusted slightly northward through 12 h, but remains the same
as the previous one until the system dissipates.

This special advisory package replaces the 100 PM CDT (1800 UTC)
intermediate public advisory.

Yeah I thought the same thing when I looked on tidbits until I saw that image posted.

yes... but you can kinda gauge wind speed off of the pressure

Every model on the planet said Marco was going to turn to swiss cheese and fizzle. Even worse than canceling in person school is they also canceled virtual school for this beautiful day.


These schools aren't making these decisions on their own. They are consulting with other government agencies, and the weather people.

Problem is, like we see with the Corona response, it's just easier to close things down, just in case.

It’s 2020. I believe anything is possible at this point. I would like to make a bet it doesn’t even land SWLA.

I don't think I've ever seen a special advisory product to DOWNGRADE a storm... crazy.

Sitting in my office looking towards Lake P... in the distance to the north, occasionally see dark clouds passing... no rain on radar... a nice little breeze and sunshine outside... this is just bizarre.
