#PTCNine - Twitter Hashtag

9 months ago

Quite the difference between the operational Euro and the AI model, with ops being west impacting the Carolinas with #PTCNine (advisories coming at 5PM EDT per NHC) - and the AI out to sea. Google Deepmind also has some ensemble members staying off shore - a good challenge to see if AI can handle binary interaction with #Humberto - or if the interaction/proximity issue is overdone in the physics based models. Does seem the DeepMind ensembles lose the circulation near Cuba almost immediately, lots of uncertainty coming this weekend. If in the SE US - dust off your hurricane plan today please.

I've been working with our GIS team @BaronWeather on a hurricane impacts dashboard for enterprise. I'm curious what the night owls think. Imagine a company's assets instead of population. Helpful? Feedback welcome! #Helene #PTCNine

Va a haber ajustes a la trayectoria a las 11 PM. Más al sur, por lo que se puede apreciar. Y quizás hasta la bauticen. Tan pronto salga el boletín lo comparto. #PTCNine #Isaias

No flights into #PTCNine since this morning. So leave it up to a satellite to remotely see surface winds from space. Will #Isaias be baptized by 11 PM?

It has taken the better part of 36h, but the latest #ASCAT pass finally shows fairly good evidence of a closed, well-defined vortex with #PTC9, near the convective blow up happening well south of #PuertoRico (15.5N/66W). Also, note all the >34kt winds north of the island.

For those with family in #PuertoRico, here is what we will likely see for wind speeds in #SanJuan from #PTCNine #PTC09 over the next 24 hours. For the USA, we still need to see where the center is past #Hispaniola.

Did this 2330Z flight get cancelled? Why are we not flying into #PTCNine? No flights since this morning.

Latest GFS run of #PTCNine / #PTC09 has the storm turning north short of #Florida - impacting the western Bahamas which took the worst from record breaking #Dorian a year ago.

NHC 11 PM: "The disturbance has not become any better organized since the previous advisory". Clearly they're expecting a center to form on the southern side of the large gyre linked to #PTCNine. Still tons of uncertainty on the future of what is still a tropical wave.
