Dean is starting to look a little ragged right now. Likely beginning to see an ERC take place, since the main "CDO" area has expanded a bit, as has the windfield, although the eye continues to shrink. An ERC should be underway this afternoon.

Looking at the steering currents, could it move WSW and hit Belize instead of the Yucatan?

so all the model tracks COUNT on/DEPEND on a high pressure ridge building in and the ULL continuing to move at a GOOD RATE of speed , i guess as long as the Ull keeps moving like it has since midnite the Ull will be in position to allow the ridge to build in, the question i have is will it (the ridge) and is the ull movement since last nite (wsw) in line with what was forecast.

Agreed, which is REALLY bad news for Jamaica and maybe Hispaniola, as strengthening will likely take place after the ERC, and Category 5 could be achieved.

the 12z GFS is once again initializing the storm way too weak (1002mbs).

Pretty pathetic considering this is actually a sub-930mb Category 4!

Well for one it could mean that the center would stay over water instead of making a 146 mile trek down the length of Jamaica. It would also bring some of the mountains in Cuba into play a little more on the north side of Dean. The worst impact is that it brings it a little closer to the ULL which could impart track further to the north.

Re: Hurricane DEAN: Global Models=12z GFS is rolling in

#7994 Postby LSU2001 » Sat Aug 18, 2007 10:34 am

I thought one of the pro-mets (wxman57 maybe) was taking about how storms are not really affected by the idea of momentum because of the fluidity of the system. In my experience I have seen storms make very sharp turns even when they were expected to maintain a relatively straight course. Not saying this will happen but with strong hurricanes but I never rule anything out until well after landfall.
JMHO,
Tim

24hrs.. http://www.nco.ncep.noaa.gov/pmb/nwprod ... n_024l.gif
500mb.. http://www.nco.ncep.noaa.gov/pmb/nwprod ... 0_024l.gif

Shows a 1005mb storm..which by GFS standards would probably indicate a ~1000mb TS. Not very impressive and WAY too weak considering this will likely be a Category 5 storm in 24 hours.

I am not surprised that the bananas were all destroyed. Banana trees do not stand up well in wind.
Mount Pelee is the volcano you are talking about and it is in the Northern part of the island.
We are still concerned at the lack of more news from the island.

Should the winds be raised to 155 mph?
