Slow move W noted on Radar

#1 Postby Frank P » Sat Sep 04, 2004 2:56 pm

Last couple of frames show the inner side of the west eye wall moving slowly west...... also reported on TWC but I needed to see it to believe it...

just hit me how amazing the forecasting on this storm was....considering the model divergence......ft pierce has been pegged for days.

although the intensity forecast left someting to be desired...especially considering the models they use to forecast strengthening was calling for weakening and that was ignored...

I compared two radar loops that end at 18:16 UTC and the other at 19:57 UTC and it does appear to have moved a little west, or slightly north of west. Also, the convection coming onshore is much stronger now.

the western eyewall is not 60 miles offshore.....landfall is defined when the outermost of the eye touches land......that will be in about 3 hours at present rate.

No, I understand landfall as when a hurricane crosses the shore (meaning the lowest barometric pressure is read onshore). If the outer eyewall of Frances touches the shore, it (the center) will still be over water, thus not making it 'land' falling.

Based on GR Level III, I'd say it's moving west, or just south of it.

I've been watching this loop (small - 4 frames) for the last couple of hours, and it has moved to the west some. Interesting little vortex rotating around in the larger eye feature. Also looks like Melbourne's about to get some bad stuff.

That is correct! Now if a storm has no closed eye what is the call then? Since they would use recon for fixes(find lowest press.) and NOT radar I would say the last recon before shore line would be a close enough fix to call it!

Also looks like the squalls/bands that come on shore are maintaining themselves pretty well. If theis motion continues, SWFL will soon be under the gun (again)...

Can I clear up the direction arguement:

11:00am 26.9N Latitude 78.8W Longitude

2:00pm 26.9N Latitude 79.0W Longitude....-Moving West

5:00pm 26.9N Latitude 79.3W Longitude....-Moving West

In short, the storm is drifting west.

I thought eye wall too, but unless I totally misunderstood them, TWC said landfall was considered when the CENTER of circulation crossed the shore, which with Frances was in the middle of what we see as the big eye.

Looks like W Palm Beach will see the eye if Frances is moving west.
