RIDGING DOWN THE EASTERN SEABOARD AND WESTWARD FROM THE BAHAMA
ISLANDS. SURFACE RIDGE AXIS REMAINING OVER SOUTH FL/FL STRAITS
RESULTS IN A WESTERLY/OFFSHORE FLOW. WEAK PRESSURE GRADIENT WILL
ALLOW AFTERNOON SEA BREEZES TO FORM...PUSH INLAND WHERE THEY WILL

92L is gone from the navy site RIP~ NOT...& rose from the dead as 93L less than a day later. It is Hurricane Gordon.
HURRICANE GORDON ADVISORY NUMBER 17
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL AL072006
1100 PM AST THU SEP 14 2006
...GORDON STILL A MAJOR HURRICANE OVER THE CENTRAL NORTH ATLANTIC...
THE 1100 PM AST POSITION...30.6 N...54.3 W. MOVEMENT
TOWARD...NORTHEAST NEAR 9 MPH. MAXIMUM SUSTAINED WINDS...115 MPH.
MINIMUM CENTRAL PRESSURE...960 MB.
Watching the interaction with the ULL to the NE...behind this is a building high that is suppose to weaken the ULL...It's proved interesting, Gordon has strengthed so he's scaring the ULL away as it is weakend...Today the ULL got caught in the middle of a triangle of Gordon, Florence & the high...it's no more.
TROPICAL STORM HELENE ADVISORY NUMBER 11
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL AL082006
1100 PM AST THU SEP 14 2006
...HELENE CONTINUING WEST-NORTHWESTWARD OVER THE EASTERN TROPICAL
THE 1100 PM AST POSITION...14.5 N...38.9 W. MOVEMENT
TOWARD...WEST-NORTHWEST NEAR 15 MPH. MAXIMUM SUSTAINED WINDS...45
MPH. MINIMUM CENTRAL PRESSURE...1003 MB.
That's what's on spagetti models at the moment...There has been a general trend of the models moving it farther westward befor a recurve. At this point Bermuda is at greater risk than a few days ago. Helena has been slow to organize, her monsterous girth will slow her even more. The longer she stays a TS the farther she should go west. Also the 1st trough that was planning to grab her looks to be trying to break off a low east of Northern Fl. This would shorten the trough enough to miss her. Should be more troughs to follow...Don't freak yet:)
There is a blob on the NE side of the Windward Islands ~ got the inverted V shape happening. Watch on...
Back to the blob tryin to form east of Jacksonville. Tailend of a front that moved through today...surface observations in the area. Saw as low as 1004 mb in the area earlier. 1010.7 when it crossed here. Probibly be an invest moving NE at best, though one model formed it to a TD.
