Hurricane Maria

Cyclone Tracy · Unread post by **Cyclone Tracy** » Tue 19/09/2017 12:45

Maria has turned from a Tropical storm to a Cat 5 Hurricane (U.S scale) within 48 hours. Incredibility has dropped from 981 hPa to 928 hPa in the last 24 hours. The eye cleared out in the last 6 hours. She warmed within the core on the cloud tops from -42c to +10c during this time. Currently smashing Dominica.

Currently 924 hPa - winds around 260 km/h, gusts to 315 km/h. Solid Cat 5

Maria has just ripped Dominica to shreds. Landfall has weakened her to 942 hPa , sustained winds around 250 km/h but she is going over water again and gaining. Heading to Puerto Rico and the Virgin Islands now.

She has dropped to low 930s again, core is also warming. Dominica completed wiped out by 300 km/h winds.

She is now around 929 hPa, sustained 260 km/h, gusting over 300 km/h. Maria is a cat 5 again. Another gargantuan warm cored gyre within 10 days of Irma. If the high pressure ridge weakens, she will travel more NW and maybe miss the U.S but who knows....the big models got Irma drastically incorrect 7 days out.

920 hPa, sustained winds around 270 km/h, Cat 5.

Hurricane Jose now plays a critical role for a Maria U.S landfall. If Hose hangs in there and keeps weakening the ridge, Maria will drift north away from Florida and go into a hurricane graveyard. If Hose weakens and disapates in the next few days, the ridge will strengthen and steer Maria NW towards Florida.

Hurricane hunter just recorded 916 hPa, inside the eye now 21c. She is still maturing ATM.

Cyclone Tracy · Unread post by **Cyclone Tracy** » Wed 20/09/2017 09:53

Now dropped to 913 hPa and 275 km/h sustained winds.

She is still bombing, 910 mb, around 280 to 290 km/h. Core holding temperature. Gusting well into KABOOM territory. Some would say she is heading towards category 6 stage.

Check out her evil face on a recent sat snap

909 mb, surface sea temps now near 30c, very favourable wind shear. Eastern side of the eye wall has weakened slightly but it's still overall holding strong.

She is heading straight for Puerto Rico which has a population of 3.4 million.

Cyclone Tracy · Unread post by **Cyclone Tracy** » Wed 20/09/2017 16:15

Currently around 908 mb, 290 to 300 km/h sustained and gusts in the eye up to 350 km/h. Temperatures around the eye and eyewall are remaining stable. She is a atomic.

Cyclone Tracy · Unread post by **Cyclone Tracy** » Wed 20/09/2017 19:41

Steady at 913mb, she has double eye wall structure now. Getting very close to landfall.

Cyclone Tracy · Unread post by **Cyclone Tracy** » Thu 21/09/2017 15:15

She officially made landfall as a high cat 4, 917 mb, sustained winds around 250 km/h, gusts near 300 km/h. The devastation on Puerto Rico is now just emerging. It's basically catastrophic.

She now is downgraded to a cat 2 but is slowly strengthening over water again, heading NW.

Still a cat 3 and inching NNW. Could become a cat 4 again with favourable conditions in 36 hours. Interestingly, GFS is now slightly pushing NNW with the ridge strengthening. This has come about with former Tropical Storm Jose starting to collapse. U.S landfall is still only a 20% chance but it was 1% chance 48 hours ago.

This footage is incredible around the eyewall of Maria. I've heard of this before but never seen it. Basically mesovortices from multiple directions within 3 minutes.

Uncanny seeing the white car move

Hard to find shelter with the wind attacking from multiple directions so quickly.
Thanks for the link, Cyclone Tracy

No worries Orion.

It's a phenomenon that is truly hard to explain. It would be a storm chasers worst nightmare if they are sheltering on one side of a building. By far more dangerous than the normal sustained winds of a cat 5 hurricane / cyclone.... and that is saying something.

Eye walls don't normally have lightning but I have seen Harvey, Irma, Maria and cyclone Debbie all spark when maturing in the last year. Basically, they are spawning atomic thunderstorm cells near the inner warm core and this video is what they can produce

I thought the video was rather boring.
I was expecting images of the wall of the hurricane?

Wow, that is awesum. I'm not sure if I'd love to see that for real, or to be very afraid of being caught out by something like it.

Harvard study estimates that Hurricane Maria official death toll of 64 was grossly underestimated. If the study is accurate, it would be that greatest death toll in American hurricane history.
