+60: 02/1800: 18.6S 146.4E: 190 [355]: 105 [195]: 926


If those figures are right this cyclone has the potential to be one of the worst to ever strike the Queensland coast. Storm surge can be a huge problem with Queensland cyclones, and the penchant in recent decades for living on the waterfront, putting far more people potentially in harm's way than when similar systems have hit in the past, is likely to lose a lot of its appeal if /when this one hits.

The Queensland chamber of commerce has already come out and I quote , said "this could be the largest cyclone to ever hit this region" I think that is pretty significant

No reason this system doesn't go on to become a 4/5 on the US scale yet alone on the Aussie scale, system is looking large and impressive at this stage and a big landfall looks just about certain right now.

Going to be a very nervy few days I feel for those in the possible firing line, esp with such a large radius of high winds expected by the models.

Mind you the inner core is a little on the large side, they don't tend to wrap up too well when they are as chunky as that I tend to find so we'll have to wait and see...

REMARKS:
311500Z POSITION NEAR 13.5S 159.5E.
TROPICAL CYCLONE (TC) 11P (YASI), LOCATED APPROXIMATELY 875 NM
EAST-NORTHEAST OF CAIRNS, AUSTRALIA, HAS TRACKED WESTWARD AT
19 KNOTS OVER THE PAST SIX HOURS. ANIMATED INFRARED SATELLITE
IMAGERY SHOWS DEEP CONVECTIVE BANDS WRAPPING TIGHTER INTO THE LOW
LEVEL CIRCULATION CENTER, FUELED BY EXCELLENT RADIAL OUTFLOW. THE
CURRENT INTENSITY IS BASED ON A SOLID DVORAK ESTIMATE OF 90 KNOTS
FROM MULTIPLE AGENCIES INCLUDING KNES, PHFO, NFFN, AND PGTW. TC 11P
IS TRACKING ALONG THE NORTHERN PERIPHERY OF A DEEP SUBTROPICAL RIDGE
(STR) POSITIONED TO THE SOUTH. THE SYSTEM IS EXPECTED TO TRACK
WEST- BECOMING SOUTHWESTWARD AS THE STR SHIFTS EASTWARD WITH THE
APPROACH OF A MID-LATITUDE SHORTWAVE TROUGH FROM THE WEST. UPPER
LEVEL ANALYSIS INDICATES THE SYSTEM HAS DEVELOPED A MESOSCALE
ANTICYCLONE ALOFT AND CONTINUES TO TRACK ALONG AN AREA OF LOW
VERTICAL WIND SHEAR. IN VIEW OF THE FAVORABLE ENVIRONMENT, TC YASI
WILL CONTINUE TO INTENSIFY, PEAKING AT 125 KNOTS BY TAU 36. THE
AVAILABLE NUMERICAL GUIDANCE IS IN EXCEPTIONALLY CLOSE AGREEMENT
THROUGHOUT THE FORECAST PERIOD. TC 11P IS FORECAST TO MAKE
LANDFALL JUST SOUTH OF CAIRNS AS A LARGE 100+ KNOT SYSTEM AFTER TAU
48 AND SHOULD DISSIPATE OVER LAND BY TAU 72. MAXIMUM SIGNIFICANT WAVE
HEIGHT AT 311200Z IS 23 FEET. NEXT WARNINGS AT 010300Z AND 011500Z.//

I think given its large size and wind distribution, the winds might be a bit less than Dvorak estimates. But this thing is so huge the IKE if measured would be enormous...

Wow thats quite insane forecast, with 125kts at landfall expected and its massive size this one really is going to be the one to watch, probably the biggie of this season from the looks of things.

This is going to need close watching.

Still not super impressed though with the inner core, its still struggling and IMO these struggle to go above 100kts...but then again with the sheer insane size of it, 100kts is still dangerous for sure...its going to be very similar to Ike!
