When the official center of the storm gets off shore, will the rain and weather increase over the western side southwest of the storm? I have too, noticed that all day long the bulk of the convection has seemed to be southwest. It seems like weather is triggered a lot further from the center of the storm.

This is probably better being answered by a MET. I've noticed the same 'runup' on the SW Quadrant.
My best guess is either lifting or forcing of the air currents. Or both. Wind currents over the GOM are picking up warm moist air and it's rising and condensing once it arrives over land.
Strange that it's not doing the same over the Atlantic side. The SSTs there shouldn't be much different that the GOM. ( 2 degrees cooler in the Gulf Stream...maybe )

Pressure in Merritt Island is 998. Looks like as more of the COC is off the coast, that the pressure is starting to drop.

It's not quite there yet. CCAFS mesonet data shows it's almost there, but still over Merritt Island as of 0200 UTC.

what direction is Ernesto moving in right now and will this motion continue? Also should I still look for a landfall in or close to Charleston, SC and if not where? I believe landfall will be Cape Romain, SC . Here's a map to find it because I ad a hard time myself especially not being in/from SC. SC MAP

If I'm reading the Melbourne Wind Profiler correctly. It's not taking long for the above ground wind speeds to incease.
From 0127Z to 0215Z.
At 2000ft above ground level: Increase from 25kts to 35kts.

Titusville has been reporting NW winds since 10pm (per TWC website) wouldn't that put the center North and East of them?

EDIT: 10:25pm WNW

The center is still passing over KSC. Our wind direction range from 20-332 degress. Wind speed in 1 minute averages is ~6 knots, and that is also the 10 minute peak average.

It would if it was a reliable wind direction. I think it was off by a little, however, since KTIX was due east at 0100 UTC (9PM). As of 02 UTC (10PM) the Cape Mesonet showed winds out of the N and NNE around that area. Winds on the southeast side of the tower network were from the south. You could clearly see the center was not quite out onto Merritt Island, Just NE of the city of Cocoa. As of 1030 PM it was out over the island and will just be moving offshore right around 11PM.

Looks like Ernesto is above to get an eastward shove from the front/ trough passing throught Panama City Beach area.

would that shove take him farther away from the coast and Ernesto could end up brushing the outer banks and not make landfall in SC or NC right?

Ernesto [Re: danielw]
      #72893 - Wed Aug 30 2006 11:18 PM

The Melbourne VAD Profiler is now-0309Z, up to max wind of 38kts at 2000ft.

Dr Steve Lyons, at TWC, just mentioned the 'possibility' of NHC issuing a Special Statement to bring Ernesto back to Tropical Storm strength during the night.

Yes, that would be one of the possibilities. It depends on how much "push" the front has to it.
The dry air portion of the front (seen on the GMX loop) has pushed across SW MS in about 5 hours.

is there a site or map I can see that tells me the strength of fronts like one that tells the strength of low pressure areas?

Caution [Re: danielw]
      #72898 - Wed Aug 30 2006 11:36 PM

For those that are currently north of Ernesto in Ga, SC, NS and the Mid Atlantic States.
Please pay close attention to your Local NWS Ofice Bulletins, Watches and Warnings. Current forecasts are based on Ernesto's current status. Forecasts can and will change should Ernesto regain Tropical Storm status.

The Weather Channel has just updated the NHC advisory to bring Ernesto back to Tropical Storm status~danielw
