I seem to recall many cyclones weakening just prior to landfall, which makes me curious if dry air is playing a role? Hopefully we can see something similar happen with Patricia.


There was some discussion of that a few pages back. This storm could be a good study for future.

I have not felt this sick watching a hurricane since Katrina.

Some locations along the Coastal Plain from S Texas to the Upper Texas/SW Louisiana Region could easily see 12+ inches depending on where the Coastal Low tracks and where the 700/850mb vort from Patricia tracks.

This is Haiyan all over again - and I have friends there.

I hope so much that radar images were taken of this hurricane from recon, the same with photos from inside to capture the pinhole eye with its grand stadium (under good moonlight conditions and lightning in the eyewall). I don't know how bad the flight was for these heroes so maybe it was chaos at the time and this wasn't possible. Wouldn't it be stupid crazy to see all that?

To see the forecast calls for strengthening to 180 knots, yeah that's a new level of absurd that none of us ever thought we'd see. No one has mentioned this, but if the SS scale continued this would be a legit category 6 hurricane. In terms of media attention, CTV news here in Canada did a good job at the start of the 6:00 am broadcast to mention how it was the most powerful hurricane in the WHEM and Epac, followed by some other details. CNN mentioned it briefly at 6:46 am EDT.

Its not, you may not have been here but if you followed it since last evening it was truly among the most insane things I've ever seen in weather overall. Its definitely the most spectacular thing to happen in the Epac and in the Top 3 for the western hemisphere, Top 5 worldwide.

You can just see the furious power of this thing and how a good chunk of MX is already getting its cloud shield/rain. The way its behaving on satellite is really amazing and different, bands just popping everywhere around the buzzsaw and how it just pops or morphs rapidly out from the main CDO...very freakish. Never seen anything like it, I think its hanging out in the 870s club bigtime.

Cyclenall, well stated! You can not express enough how surreal it was watching Patricia make history overnight. I have run out of superlatives to tell you the truth!

Yeah, that's all fine, but it sounded like the guy needed a cigarette.

A Tropical Storm Warning is in effect for...

hours. Preparations to protect life and property should be rushed to
completion.

A Tropical Storm Warning means that tropical storm conditions are
expected somewhere within the warning area.

A Hurricane Watch means that hurricane conditions are possible
within the watch area.

For storm information specific to your area, please monitor
products issued by your national meteorological service.


DISCUSSION AND 48-HOUR OUTLOOK
------------------------------
At 700 AM CDT (1200 UTC), the eye of Hurricane Patricia was
located near latitude 17.3 North, longitude 105.6 West. Patricia
is moving toward the north-northwest near 12 mph (19 km/h). A turn
toward the north is expected later this morning, followed by a turn
toward the north-northeast this afternoon. On the forecast track,
the core of Patricia will make landfall in the hurricane warning
area this afternoon or evening.

Maximum sustained winds remain near 200 mph (325 km/h) with higher
gusts. Patricia is a category 5 hurricane on the Saffir-Simpson
Hurricane Wind Scale. Some fluctuations in intensity are possible
today, but Patricia is expected to remain an extremely dangerous
category 5 hurricane through landfall.

Hurricane force winds extend outward up to 30 miles (45 km) from the
center and tropical storm force winds extend outward up to 175 miles
(280 km).

The estimated minimum central pressure is 880 mb (25.99 inches).


HAZARDS AFFECTING LAND
----------------------
WIND: Hurricane conditions are expected to first reach the
hurricane warning area this afternoon. Tropical storm conditions
are beginning to spread across portions of the warning area.
Preparations to protect life and property should be rushed to
completion. Hurricane conditions are possible in the hurricane
watch area later today.

RAINFALL: Patricia is expected to produce total rainfall
accumulations of 8 to 12 inches, with isolated maximum amounts of 20
inches, over the Mexican states of Nayarit, Jalisco, Colima,
MIchoacan and Guerrero through Saturday. These rains could produce
life-threatening flash floods and mud slides.

STORM SURGE: An extremely dangerous storm surge is expected to
produce significant coastal flooding near and to the right of where
the center makes landfall. Near the coast, the surge will be
accompanied by large and destructive waves.

SURF: Swells generated by Patricia are already affecting portions
of the southern coast of Mexico, and will spread northwestward
during the next day or so. These swells are likely to cause
life-threatening surf and rip current conditions. Please consult
products from your local weather office.


NEXT ADVISORY
-------------
Next complete advisory at 1000 AM CDT.

Ah I'll just agree to disagree. I mean the last pass had 192kt flight level winds and 180kt SFMR winds were confirmed through VDM. The pressure was still falling as well.

Jup, I would've liked to see them go sub-880 and to their forecasted peak of 180 knots

I think Patricia will be bumped up to 180 kt at the TCR, with a pressure of 877mb. But it is a matter of semantics, really. Either way, the damage will be like that of Haiyan in Tacloban.

I don't know if a storm of this intensity is even possible in the Atlantic...or in the EPAC outside a strong El Nino.

Patricia is forecast to slightly strengthen? I have zero knowledge on how strong hurricanes can possibly get but I have to think there's got to be a speed limit based on earth's physics at some point.

Maybe super storms are not prone to ERC's?


Haiyan did. It's just that it did not weaken at all during the eyewall replacement

I would say a post-season upgrade depends on 18Z recon.

A couple of points one way or the other is only for statistics now. Can't imagine the coastline there tomorrow.

Had Wilma not lost its core over Cozemul, it may have made a run at this intensity in the southeast Gulf given the very favorable upper level pattern it had. Remember, it intensified very quickly despite not having a core
