    Note that the instruments could be calibrated slightly different which would result in slightly different readings. Dropsondes should be around 912-914mb since extrap tends to be a bit low.

    Aviation and shipping are still in knots and wind affects them more than people day to day. Impressive pass. Doing the typical 10% deduction from flight level winds to get SFC results in 135kt/155mph.

    There’s not a double wind maxima showing yet on any passes so not an EWRC yet. Also, I haven’t seen any double eyeball structures on the morning microwave satellite passes.

    NOAA2 only got 127kt SFMR unflagged in the NE eywall. It got 139kt max flight level so I feel like 125-130kt is where it’s at. 140130 2602N 07311W 7523 02098 9565 +156 //// 117117 136 127 042 01 140200 2603N 07311W 7531 02181 9677 +135 //// 117136 139 122 058 01

    How an SFMR works: https://www.prosensing.com/crb-product/sfmr/ TLDR: It uses brightness temperature at the surface to calculate wind speed.

    Not showing as flagged on Tropical Tidbits. VDM will confirm whether it’s flagged or not when we get that. It seems anomalously high to me compared to the pass NOAA just made through the NW eyewall.

    AF302 just got 131kt flight level, 141kt SFMR in the NE eyewall. 144kt SFMR was flagged

    ADT from NOAA and UW CIMSS both still under CI#6.

    I'm not a modeling expert, but from my understanding the grid spacing in global models is too large to accurately resolve the minimum pressure. This results in the scaling issues mentioned above. The overall storm is modeled well enough that the globals can handle the track.

    WC130J aircraft entered service in 2005. RPAs have extensive limitations when it comes to making quick corrections which limits the current RPAs, especially in bad weather. Basically humans are still way better at flying through the turbulence of a hurricane than an RPA.

    NOAA2 is going to be heading into the storm very soon. Current CI#=5.8 per UW CIMSS which estimates 950mb/110kt. I could see it being slightly higher than the estimate but I don’t think it’s above 120kt based on the current satellite presentation.

    The downstream effects on the east coast from it. A stronger ridge west will weaken ridging on the east.

    Down to 970mb per last eye dropsonde.

    AF303 has turned around and is heading back west. Looks like no recon for a while after AF302 departs the storm.
