Given that it's already a TS as per the best track they'd probably issues advisories as a post-tropical system if it transitions before reaching the coast.

The cold air has wrapped to the eastern side of the low now (the front). It may have some warm air aloft, but it’s a frontal low.

Definitely starting to degrade in appearance on satellite = transitioning to frontal. I doubt they go through the trouble of issuing TS Warnings. I've already done my gumbo and booze grocery store run, that's the cool thing about having fall tropical systems in south Louisiana :lol: .

One thing this system has that Nestor never had is a well defined LLC, like I mentioned earlier today.

Second pass coming in from the SE quadrant, still showing a warm core, with no signs of the LLC being attached to the frontal boundary.

The cooler air/front is just a few miles away from the LLC on the NW quadrant.

I believe post season this will likely be extended back 12 hours as a tropical storm. Has looked about the same since around that time frame.

What I have been saying all afternoon, that the LLC is not yet attached to the front:

    Tropical Storm Olga Discussion Number 2
    NWS National Hurricane Center Miami FL AL172019
    400 PM CDT Fri Oct 25 2019

    Although Tropical Depression Seventeen began looking less and less
    like a tropical cyclone in satellite imagery, scatterometer data
    and reports from an Air Force Reserve Hurricane Hunter aircraft
    indicate that so far the tropical cyclone remains just ahead of the
    approaching cold front, with the aircraft showing the front located
    about 25 n mi from the center in the southwestern quadrant
    . In
    addition, the aircraft and scatterometer data indicate that the
    cyclone's winds have increased to 35 kt in the northeastern
    quadrant. Based on this, the depression is upgraded to Tropical
    Storm Olga. It should be noted that a large area of 35-45 kt winds
    is occurring west of the cold front over the western Gulf of Mexico,
    although these winds are more due to the cold air surging across the
    Gulf than to the cyclone's circulation.

Well, the Euro did much better with this system than with Nestor of this becoming a TS.

Heavier rains filling in now over the area, looks like the worst will be from now until about midnight for the Lafayette area.
