StormChaser4Life Posted October 31, 2020 That island definitely impacted Goni. Eye has shrink considerably after passage over it. Hopefully this can bring the intensity down some but regardless this will still be a catastrophic cat 4-5 across the Philippines 1 Quote Share this post Link to post Share on other sites

StormChaser4Life Posted October 31, 2020 Goni has definitely degraded quite a bit on satellite in its inner core. Curious what the intensity is now Quote Share this post Link to post Share on other sites
vortex95 Posted November 1, 2020 Goni as strong as Haiyan? Going strictly by satellite here. I did a comparison of EIR and BD geostationary imagery (4 km resolution) at Goni's and Haiyan's peak intensity of 170 kt. Goni EIR 10/31/20 18z 170 kt https://rammb-data.cira.colostate.edu/tc_realtime/products/storms/2020wp22/4kmirimg/2020wp22_4kmirimg_202010311800.gif Haiyan EIR 11/7/13 1830z 170 kt https://rammb-data.cira.colostate.edu/tc_realtime/products/storms/2013wp31/4kmirimg/2013wp31_4kmirimg_201311071830.gif Goni BD 10/31/20 18z 170 kt https://rammb-data.cira.colostate.edu/tc_realtime/products/storms/2020wp22/4kmsrbdc/2020wp22_4kmsrbdc_202010311800.jpg Haiyan BD 11/7/13 1830z 170 kt https://rammb-data.cira.colostate.edu/tc_realtime/products/storms/2013wp31/4kmsrbdc/2013wp31_4kmsrbdc_201311071830.jpg Haiyan looks more symmetrical with a thicker/colder CDO ring and warmer/clearer eye. ----- Comparison of Polar EIR imagery (1 km resolution) Goni EIR 10/31/20 1225z https://rammb-data.cira.colostate.edu/tc_realtime/products/storms/2020wp22/1kmirimg/2020wp22_1kmirimg_202010311225.gif Haiyan EIR 11/7/13 1640z https://rammb-data.cira.colostate.edu/tc_realtime/products/storms/2013wp31/1kmirimg/2013wp31_1kmirimg_201311071640.gif Polar imagery is not at the same time but still Haiyan looks so much more impressive overall for its cold COD ring and a warmer/clearer eye overall. Geostationary imagery for Goni at 18z does not suggest its satellite presentation improved to this level from 1225z. 1 Quote Share this post Link to post Share on other sites

Morris Posted November 22, 2020 Even in a year full of RI events, what Gati has done today is extremely impressive. LOOK: Tropical Cyclone 03A (#Gati) "explosively" intensified from a minimal Tropical Storm to a (Category 3-equivalent) Severe Cyclonic Storm in just 12 hours. According to JTWC, it is now bearing down on Somalia with 1-minute maximum sustained winds of up to 185 km/h. https://t.co/IqtOEWXsSS 1 Quote Share this post Link to post Share on other sites

Gati came out of nowhere, was not modeled by any guidance near this intensity. There is no historical record of a Cat 3 landall in Somalia, though I suspect in years where upwelling off of the NE Somaliaan coast, OHC at near surface might be warm enough on occasion. Still, generally too arid an environment to support such intensities. Takes more than SST support. Just a really phenomenal cyclone. Gati does appear to be weakening into landfall. Unfortunately it may be too late for weakening to mitigate impacts to higher population center as these folks have rarely ever experienced hurricane force impacts to a weak infrastructure. 1 Quote Share this post Link to post Share on other sites
Calderon Posted November 22, 2020 I've been tracking that from over here because I'm responsible for that region & JTWC dropped the ball big time. 2 days ago there were 2 well-defined clusters with evident surface circulation, and in the span of 2 hours last night, one group of storms exploded & closed off the eye. It was bombs away very fast then. Already forecasting flooding in Djibouti, because well, it happens in a scenario like this with ease over there.

Windspeed Posted December 15, 2020 Fiji looks to be on the receiving end of a cat 3 landfall in a couple of days if the track forecast holds.Make that a Cat 5 on the Aussie scale. JTWC presently has it at 110 kts and expectss further intensification.

Without recon we will never know for sure what these WPAC beasts are really obtaining. Once you start maxing out T it’s hard to differentiate between 175kts and 200 and 900 and 870. 2 Quote Share this post Link to post Share on other sites
