Looks to be rapidly closing up

It also looks to be tracking significantly farther east than even the HWRF. At this rate the formative eye could just “scrape” the easternmost Isla de la Juventud.

No not really. There's huge confidence in the forecast track


There is never “huge confidence” in any forecast track. That’s why the cone of error is there. It also appears to be doing what Shell Mound said.

I'm going to take that value with a grain of salt as the hurricane hunters were rapidly ascending during the pass.


Yeah, I take this back. That second pass confirmed 990mb. Dropsonde was a little higher @ 992mb. Ida is quickly deepening & will likely be a hurricane soon.

My posts are my own personal opinion, defer to the National Hurricane Center (NHC) and other NOAA products for decision making during hurricane season.

996 to 992 in one pass, and to think that once this gets the gulf conditions will be better for rapid strengthening.

996 to 992, the time difference between those two passes was just over 2 hours.

Not really a joke as Ida has consistently been north and east of any projected track. It has major implications for the city of New Orleans if it keeps happening.

I was kind of thinking Betsy, but she was on a sharper NW trajectory with no curve around to the north when she hit SE Louisiana, and also the center passed closer to the city. Then I thought about Andrew, and the angle of approach is pretty similar, but he made landfall a bit west of current projections. I don't recall Andrew causing dramatic impacts for NOLA. Certainly not trying to downplay, but am wondering whether the current track, with the center crossing over Baton Rouge, would likely spare NOLA from much beyond Cat-1 winds and storm surge outside the levees and sea walls. IF it follows the exact NHC track forecast right now. I know flooding in the city from excessive rainfall will also be a major problem no matter where this lands.

Camille


Camille wasn’t on this track. Went east of New Orleans and hit Mississippi.

So I guess we won't get any further recon in the storm until it crosses over Cuba and emerges into the Gulf?

WOW grabbed a couple hours sleep, and wake up to what feels like a gut punch looking at the the models. And I knew it would be a monster since yesterday, but dang this is so worse case!

What makes you so sure? It is on radar heading to the eastern side of the island. Probably going to make landfall.

Definitely seems like there was a bit of a reformation/snap of the center towards the deeper convection, which was (and still is) mostly on the northern side.

Given the current rate of intensification Ida could conceivably approach MH status at LF on western Cuba. I think 80–90 kt/970–975 mb seems quite likely, given the observed rate of deepening and organisation observed by radar, satellite, and reconnaissance. Ida’s current track, along with its relocated centre, would minimise interaction with the Isla de la Juventud and would maximise the storm’s time over the Gulf of Batabanó prior to landfall on the Cuban mainland. If I recall correctly, the most aggressive model run to date only suggested that Ida would approach ~70 kt/~985 mb at landfall on western Cuba. Ida currently looks to be at least 10 kt/mb stronger than that by the time it impacts western Cuba.

But Camille went east of New Orleans, although wow. The track is eerily similar other than that!

Is recon done for sure? They just took a north turn

It’s going to spend much of tomorrow over the Loop Current and might be a hurricane upon entering the Gulf…this is a very, very bad combination. I could see it reaching major hurricane intensity as early as tomorrow’s 2pm intermediate advisory.

This is gonna explode tomorrow afternoon.

I am only a meteorology enthusiast who knows a decent amount about tropical cyclones. Look to the professional mets, the NHC, or your local weather office for the best information.
