10/18/05 NOW: Hurricane Wilma

"I dunno how they do it, but WeatherTAP is updating the satellite every ten minutes or so with a picture that's only a few minutes old when it posts."

GOES-East is in rapid scan mode, which they do always for hurricanes and quite often for severe weather events when requested by a WFO.
 
The same can be seen at http://www.cira.colostate.edu/RAMM/Rmsdsol...ol/RSOMAIN.HTML (the RAMSDIS Rapid Scan page) and http://www.cira.colostate.edu/RAMM/Rmsdsol...l/TROPICAL.html (the RAMSDIS tropical page, as you probably could have guessed -- has nice rapid-scan, zoomed visible loops). The motion is NNW as others have mentioned, though there was a recent wobble to the nw. I'm not as skeptic as those who are skeptic of the model solutions of meandering Wilma around the Yucatan for a while (that doesn't really make sense, but hey, it 415am).

The western eye wall has filled with convection rather stoutly over the last couple hours. Perhaps a Cat 5 but a few mph is not going to make much difference on Cozumel and around Cancun. Unfortunately, I think we will see tremendous damage on the news over the next few days. Hurricanes have either aimed at or gobbled up population centers this year.
 
Here are a couple of links for Cancun and Cozumel with some impressive data.
Cancun: http://smn.cna.gob.mx/productos/emas/pagin...nas/cancun.html
Cozumel: http://smn.cna.gob.mx/productos/emas/pagin...as/cozumel.html

Those wind gusts ~220km/h in Cancun are insane! Also a sweet value of pressure in Cozumel, 927hPa.

Anyone noticed this thing is NHC AN26:
WILMA IS EXPECTED TO PRODUCE 10 TO 20 INCHES OF RAIN THROUGH
SUNDAY ACROSS PORTIONS OF WESTERN CUBA AND THE YUCATAN PENINSULA...WITH ISOLATED AMOUNTS OF 40 INCHES POSSIBLE. OUTER RAINBANDS WILL CONTINUE TO AFFECT PORTIONS OF SOUTHERN FLORIDA... ESPECIALLY THE KEYS... WITH SOME 2 TO 4 INCH RAINS POSSIBLE THROUGH SUNDAY.

Wilma is moving towards NNW pretty slowly, this ain't a good thing.
 
A dropsonde picked up 137 knots at the surface in one of the eastern eyewalls.

Now that's insane! :shock:

EDIT: Now the site says 1638mm/24h!

WOW... That's roughly 65 inches of rain in 24 hours... Absolutely incredible.
 
The eye has filled in as Wilma remains almost stationary across the Cancun area. Has anyone heard of any chasers that were able to reach Mexico? That would be a very long chase.

Looks like the eye is very near the water now. I did find a site with a bunch of pics on it... Go to http://stormcarib.com/reports/2005/mexico.shtml -- scroll through and click on the 'attachments'. Recent near the top, older at the bottom. I started at the bottom, and thought 'eh, not too bad'... They get worse near the top, presumably as the eyewall nears. Nothing incredibly impressive, as they're pretty much on the water -- interesting nonetheless.
 
I've been noticing that the storms locally here in Central Florida have had some anomalous persistent velocity return signatures. Here is an example of one:

I added the black line from the storm center (via regular old base reflectivity) through the radar site. To me, this small cell appears to have very weak rotation, but I'm not exactly sure, because it isn't a perfect 'regular' couplet. It almost looks more like a cross between a rotating storm and a heavy rainer. Sunday's forecast here calls for an increasing tornado threat, albeit a low one. Are these things related? If not, I'd like an explanation.

Edit: My apologies. The greens are inbounds.
