Hurricane Ida

Unread post by Cyclone Tracy »

Ida has formed into a tropical storm overnight south of Cuba. The latest super ensemble 2608 run 18z set for EPS and GEFS is showing a track bullseye for Louisiana in just over 3 days. Given the very warm gulf waters and low wind shear in the short term, this could be a major hurricane on landfall for the U.S. GFS is current projecting a hit on New Orleans.

Poor Louisiana. Their coastal communities are still a mess after Laura and her mates visited last year. I think surge is going to be a huge issue with Ida due to the large wind field.

NOAA hurricane hunter aircraft is currently flying through Ida. They have recorded a 4mb pressure drop in the last hour and a half. Ida will be a beast in 12 hours time.

This is the 2nd Hurricane/TC to be called Ida. TC Ida passed close to Northland on the 15th of March 1959 resulting in a lot of damage up there.

That’s a neat bit of trivia! I dare say the name Ida will be retired by the NHS after this. Now a category 4, drop of 6mb in the past hour.

GFS latest run is projecting the inner eyewall approaching New Orleans near high tide in 9 hour and 40 min from now.

Satellite (ADT) estimate coming in at 934 hPa, 127 knots. Hurricane hunter recon mission is now on its way towards the beast to drop in the new weather toys and get the actual obs. Ida has the unofficial look of a cat 5.

The new hurricane hunter data will be interesting. Cat 5 certainly on the cards. Data due in a few minutes time.

Landfall - pressure 930 hPA, 130 knots (150 mph, 241 km/h). High end cat 4. Preliminary wind estimates would tie that strength with strongest ever Louisiana canes of Laura 2020; Last Island 1856.

Ida is looking just as strong as when she first made landfall, all that hot swampy water below. Multiple mesovortices within the inner eyewall and intense rain on the outside of them. The eye is heading for the town of Houma where several storm chasers are hunkered down. They should get the stadium effect if it stays course.

Reed Timmer currently live driving in the eye around Lockport. Around 940 hpa. https://fb.watch/7HMO7UL_qm/

Still a deep very strong major cane. I'd say it associated with the Brown Ocean effect over the swamps.

7 hours after landfall, Ida still has an eye and eyewall. The damage is going cataclysmic.

Total power failure in New Orleans. Catastrophic damage to the grid that will take months to repair according to local media. Flash flood emergency now as well due to the lack of pumps that are operational. Only a few work on the back up generator power. The strength of this system blows my mind. The warm moist waters of the gulf continuing to fuel Ida through her own storm surge and swamp areas of the bayou.
