TROPICAL WEATHER OUTLOOK
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL
500 AM PDT SUN JUN 1 2008
FOR THE EASTERN NORTH PACIFIC...EAST OF 140 DEGREES WEST LONGITUDE..
A LARGE AREA OF SHOWERS AND THUNDERSTORMS EXTENDS FROM THE GULF OF
TEHUANTEPEC SOUTHWARD FOR A FEW HUNDRED MILES OVER THE EASTERN
PACIFIC. THIS ACTIVITY IS ASSOCIATED WITH THE SAME BROAD AREA OF
LOW PRESSURE THAT HAS ALREADY PRODUCED TROPICAL STORMS ALMA AND
ARTHUR. UPPER-LEVEL WINDS ARE EXPECTED TO BECOME A LITTLE MORE
FAVORABLE FOR DEVELOPMENT...AND A TROPICAL DEPRESSION COULD FORM
WITHIN THIS AREA DURING THE NEXT DAY OR TWO. REGARDLESS OF
DEVELOPMENT...LOCALLY HEAVY RAINS ARE POSSIBLE OVER PORTIONS OF EL
SALVADOR...GUATEMALA...AND SOUTHEASTERN MEXICO.
ELSEWHERE...TROPICAL CYCLONE FORMATION IS NOT EXPECTED DURING THE
NEXT 48 HOURS.

Re: EPac disturbance (former Alma/Arthur): GTWO: Orange
If this one develops in the GOT, it may be able to crossover into the BOC. The models show a large and deep-layer trough digging into southern plains later this week, that would at least break down the ridge over GOM to allow this system to come northward.

Yes indeed I was thinking the same thing so we'll have to see how this all unfolds.

I don't think we'll see any development in the Carribean this week. The upper-level winds are becoming unfavorable again there.The Pacific will win again.

Alma to Arthur to Boris to Bertha would be incredible.

The 12z GFS brings 91E northward into the southern BOC as a 1008mb low in 36 hours... http://www.nco.ncep.noaa.gov/pmb/nwprod ... n_036l.gif
1007mb low in the BOC in 48 hrs... http://www.nco.ncep.noaa.gov/pmb/nwprod ... n_048l.gif
The GFS then strangely dissipates the BOC low in 60 hours and another 1007mb low forms near Belize... http://www.nco.ncep.noaa.gov/pmb/nwprod ... n_060l.gif
A 1005mb low reappears in the BOC in 72 hours... http://www.nco.ncep.noaa.gov/pmb/nwprod ... n_072l.gif
The low is inland in eastern Mexico in 102 hours, but there continues to be quite a bit of moisture hanging over the Gulf. A new low may even be trying to form west of Florida... http://www.nco.ncep.noaa.gov/pmb/nwprod ... n_102l.gif

Re: EPAC: Invest 91E - Gulf of Tehuantepec
It is my belief that the current monsoon trough setup will be our focal point for awhile concerning EPAC and Atlantic/Caribbean Basins. Every year we have surprises, and this setup certainly is something to watch in my humble opinion.

Well once again as others have said we have another developmental battle. 91E may well end up forming first simply becuase it probably has a better set-up to work with but its goibng to have to form a closed circulation soon as models put it inland within 36hrs.
Once again the cross-over is going to have to be watched, should also be noted that current direction of this system in very close to being NE according to the data which makes the BAMS solution which brings it into the BoC fair more possible.
Also still have to watch the Yucatan region, we saw how Arthur formed pretty much straight after Alma decayed compeltely.

Remember Gatorcane..the bam models are meant for the deep tropics..they dont handle mid latitude systems so your right, the globals will be interesting.

Yep thats a good point they are just statistical models and so won't know about the developing trough that is going to help to erode the gulf high that sent Arthur to the WSW. Also right now BAMS is far the better one to use as it appears to have a better grip on how to handle this invest given its has it heading N/NN rather then NW like the other BAM's, which is line with the last 24hrs worth of movement from this invest region.
