  1. Today, 24 August 2020, marks the time three years ago when Hurricane Harvey began an RI in the Gulf of Mexico, as TS Laura appears ready to do shortly this evening. Harvey, in his Texas impacts, was actually two very different behaving storms. The initial fierce destructive high Cat 4 landfall on San Jose Island and the Rockport, TX area, then an inland excursion of about 80-90 miles NNE, with a loop-de-loop and subsequent ESE track back out to the GOM was one devastating event. The second event had a much different effect, with Harvey's further Gulf tracking and landfall east of Galveston and Houston in LA, which dumped billions of tons of rainfall, up to five feet in places, but had little wind. It all added up to the US's second most costly 'cane. Y'all maybe contrast and compare Laura with Harvey. I'll put a few links and images below. I'll try [later] to also add a few personal photos taken just before Harvey blasted into my homeport of Rockport. I got out in the last safe few hours, after securing my boat in it's slip and scooting for my inland home, which Harvey got real close to following me. Along with a few post-storm pics from various sources. This is difficult as my internet sucks.

  2. Nothing has changed, same forecast all the time, 90deg+ highs, 77-85 lows, offshore SST's 81-86deg, inshore higher. Most stations-of-record have recorded 90deg+ temps every day for 90+ days this summer. This is what Imelda, possibly Karen and/or a potential Melissa has to feed on, 27-31degC GOM bathwater: Corpus area Observations, incl GOM
  3. Indeed, 'sauna water'! As a surfer and sailor around South Padre [on that radar image, due east of Brownsville], water temps in the upper 80deg/lower90's, plus sun, with exertion would get you overheated. We [kids too] swam the very warm and saline Laguna Madre, the GOM surf, and would sail offshore 10-15 miles to swim the warm open bluewater. Until I hooked my first Great White shark... :] a young one, only about 7-8 feet long, she had beautiful dentition ^^^^. :]] If she's still out there, she's probably 16'+ now.
  4. Just for chuckles, here's a comparison of the NOAA WSR-88D radar long range base reflectivity scans of the proto-TS Imelda and the current TS Karen. The scans are from the CRP and JUA WFO's, IIRC the LR radar image scan diameter is ~500 miles. Note that the well-formed Imelda image is from about 11 hours before it's 'official' TS designation, but it wasn't being closely monitored att [surrounding gauges indicated baro falls and circulating windfield]. Imelda looked the part, but only brought an eventful rainfall and not much wind. If Karen eventually gets to the GOM it might be another major in all parameters. Pre-TS Imelda TS Karen
  5. NHC is now mentioning a "Disturbance 1" near the northeastern tip of Yucatan, it has a 10%/2day-20%/5day chance of becoming TD Melissa or 100L. I'd bet that this is the same wave that had been appearing on the earlier forecasts to the ESE of Jamaica and was dropped a couple days ago. Looks to be headed for Veracruz or Tampico, MX, but I'll just get a little nervous anyway :] . Anything around the very warm Bay of Campeche at this time of year has a chance of cooking off.

  7. Another very respected scientist and leader stands up for the good people of NOAA, and [too, imo] politely excoriates the incompetent, and sycophantic, who cravenly interfere with the scientists and technicians of NOAA. From the "Scientific American" * : Observations - Leadership In The Age Of The Surreal "Leadership in the Age of the Surreal The professionals at the National Weather Service deserve political leadership that will stand up for them—even when that puts the leaders’ own jobs in jeopardy. .Over the past two weeks, Hurricane Dorian destroyed portions of the Bahamas and posed a major threat to the southeastern U.S., before eventually making landfall in North Carolina. Given that we are in peak hurricane season, this is not an unprecedented story. In today’s age, however, the devastating hurricane became a backdrop to a political farce that, even in retrospect, seems unbelievable. ...

  8. No rational, logical, science-related or based US government policies will be possible until the place is cleaned up, reformed, until the 'swamp' is truly drained out. It's currently mostly controlled by and for anti-science, anti-factual, cultist grifters who act on a far different plane than a patriotic 'for the good of the nation' basis; when not acting on behalf of foreign interests [like RU, MbS, DPRK, etc].
  9. An apt quote, but you should attribute it to George Orwell's great [and scary] book, "1984", which I think too few today are aware of. Yet, here we are, nearly living in it. Nineteen Eighty-Four: A Novel, often published as "1984" George Orwell presented a situation where people struggle to live in a atmosphere of deceit under the pervasive rule of "Big Brother". An atmosphere of deceit where "that which is truth" is totally controlled by an authoritatively positioned ruling party. “What you’re seeing and what you’re reading is not what’s happening”
  10. The American Meteorological Society, the 'pro mets' professional group, issued a statement of support for the working NOAA staff [below]; especially those of the Birmingham, AL WFO, who corrected the 'Met-in-Chief's' absurd Sharpie forecast and his subsequent doubling down on Sharpiegate. The NOAA upper level management and spokesperson types who folded under that wholly unjustified and corrupt WH political pressure, with that unattributed public rebuke of the Birmingham WFO, should be instantly removed, no later than on 22 Jan 2021. IIRC, NOAA still only has an 'acting' director, not a permanent one, yet another example of the gross negligence of this maladministration [and subservience to VP/RU]. "Only the Best"... https://www.ametsoc.org/index.cfm/ams/about-ams/response-to-noaa-statement/ https://www.ametsoc.org/index.cfm/ams/ "Response to NOAA Statement The American Meteorological Society fully supports our colleagues at NOAA, who consistently put the safety of the American public first and foremost. They work tirelessly employing state of the art science to keep Americans safe. With respect to the press release that was issued by NOAA on Friday, 6 September, regarding the forecast of Hurricane Dorian, AMS believes the criticism of the Birmingham forecast office is unwarranted; rather they should have been commended for their quick action based on science in clearly communicating the lack of threat to the citizens of Alabama.
  11. Anybody know what the turning radius of a 280 mile wide, 70,000ft high, multi-billion ton, 185-220mph, spinning mass of water, water vapor [and some debris] might be? Anxious Floridians and EC'ers would like to know. Pls reply: Box DUG, Cheyenne Mountain, CO. Not your grandmum's Buick at all.
  12. TS Chantal is aliiive... fairly odd to have formation so far north [40N], but she's supposed to bend south into warmer SST, but more unfavorable atmo layers, at least for a while, then... 000 WTNT44 KNHC 210232 TCDAT4 Tropical Storm Chantal Discussion Number 1 NWS National Hurricane Center Miami FL AL042019 1100 PM AST Tue Aug 20 2019 Recent scatterometer wind data and passive microwave satellite images indicate that the small low pressure system that the NHC has been monitoring for the past few days has developed a well-defined surface wind circulation and contains tropical-storm-force winds south of the cyclone's center. Therefore, the low has become Tropical Storm Chantal. The initial motion estimate is 085/19 kt. NHC model guidance is in excellent agreement that Chantal will move eastward around the northern periphery of the Bermuda-Azores high and gradually slow down during the next 48 hours. Thereafter, the cyclone is forecast to drop southward around the eastern portion of the ridge, possibly stalling over warmer waters. The NHC forecast track lies close to the consensus models HCCA and TVCN. Chantal is expected to remain in a moderate southwesterly to westerly vertical wind shear regime for the next 48 hours or so, followed by a significant decrease in the shear through 120 h. After 48 hours, the southward motion is also expected to move Chantal over warmer water with SSTs around 27C. However, mid-level moisture is expected to be quite sparse with humidity values forecast to be less than 40 percent based on the GFS and ECMWF SHIPS intensity guidance. Therefore, little or no significant intensification is expected throughout the forecast period, and the official intensity forecast closely follows a blend of the HCCA and IVCN consensus models. Although the official forecast calls for Chantal to remain a tropical cyclone through the 120 h, the abundance of dry air that the cyclone will be moving through could result in erosion of the deep convection sooner than currently expected.
