The Atlantic had 91L which turned out to be nothing tropical .Let's see what this disturbance does in the EPAC.

From the TPC EPAC Tropical Weather Discussion

AT THE LOW LEVELS...A BROAD AREA OF LOW PRESSURE HAS PERSISTED
IN THE TROPICAL E PACIFIC. A CYCLONIC SWIRL DEVELOPED THIS
MORNING NEAR 9N97W AND WAS ANALYZED AS 1007 MB. A FEW TOWERING
CUMULUS CELLS ARE BEGINNING TO ORGANIZE ALONG A BAND OVER THE SE
QUADRANT. EXPECT THIS CIRCULATION TO MOVE LITTLE THE NEXT 24
HOURS THEN BEGIN TO MOVE N IN RESPONSE TO A DEEPENING TROUGH
OVER THE GULF OF MEXICO.

Basically in the exact place with the exact motion as depicted by several models for 24+ hours previously....

Something to be remembered when all the tired old anti-model rants get posted this year.

Of course, it's far from guaranteed to make it across; Central America is mountainous and much depends on the speed and precise track, how wide the area crossed is.

Even if it doesn't cross, it will be unusual in that the Pacific coast of Guatemala or El Salvador almost NEVER have a landfalling storm.

So do you guys suspect that this system may make it to Tropical Depression One-E a little while down the line?

FOR THE EASTERN NORTH PACIFIC...EAST OF 140 DEGREES WEST LONGITUDE.

A BROAD AREA OF DISTURBED WEATHER EXTENDS FROM CENTRAL AMERICA
SOUTHWESTWARD FOR SEVERAL HUNDRED MILES OVER THE NORTHEASTERN
PACIFIC OCEAN. A WEAK LOW PRESSURE SYSTEM EMBEDDED WITHIN THE

AND EL SALVADOR. THIS SYSTEM HAS SOME POTENTIAL FOR ADDITIONAL
DEVELOPMENT OVER THE NEXT COUPLE OF DAYS AS IT MOVES NORTHEASTWARD
AT 5 TO 10 MPH.

ELSEWHERE...TROPICAL STORM FORMATION IS NOT EXPECTED THROUGH
TUESDAY.

Another run of the UKMET but crossover is not a sure bet because centralamerica is like a big hurdle.

UKMET has slow movement now and it really sort of gets wiped out over Central America.

Well, any EPAC to Atlantic or Atlantic to EPAC is a cross-over; Atlantic to EPAC is fairly common, EPAC to Atlantic is rare and more interesting.

Storms are renamed when they cross, btw.

That is exactly correct.A system crossing from the Eastern Pacific crossing CentralAmerica into the Caribbean or the Bay of Campeche.Dont be afraid to ask any question here because we will help you.
