GULF OF MEXICO...
A BROAD AREA OF LOW PRES IS CENTERED OVER THE SE GULF ABOUT 240
NM NNE OF CANCUN MEXICO DRIFTING SLOWLY WWD AWAY FROM THE FL
STRAITS. THE SURFACE PRES OF THE LOW CONTINUES TO SLOWLY DROP
AND IS NOW ESTIMATED AT 1008 MB BASED ON A BUOY OBSERVATION N OF
THE CENTER. STRONG UPPER LEVEL NLY FLOW...ON THE E SIDE OF A
STRONG UPPER HIGH OVER SRN MISSISSIPPI...CONTINUES TO STREAM
FROM THE CAROLINA COAST SWD INTO THE NW CARIBBEAN AND IS
PROVIDING 10-15 KT OF VERTICAL SHEAR OVER THE SYSTEM. A
SHORTWAVE TROF HAS DROPPED SWD FROM W CUBA TO THE N YUCATAN
COAST AND BROAD UPPER LEVEL DIVERGENCE S OF THIS AXIS IS
FOCUSING SCATTERED MODERATE CONVECTION S OF THE SURFACE
CIRCULATION FROM 20N-25N BETWEEN 80W-90W. IF THE SHEAR CAN RELAX
A BIT MORE AND ALLOW TSTMS TO RE-DEVELOP NEAR THE CENTER...THE
SYSTEM DOES HAVE THE POTENTIAL FOR TROPICAL DEVELOPMENT OVER THE
NEXT SEVERAL DAYS. ELSEWHERE...A MID/UPPER LEVEL LOW/TROF ALONG
THE MEXICAN GULF COAST IS PRODUCING MODERATE SUBSIDENCE TO ITS
E...BRINGING RELATIVELY DRY WEATHER TO MUCH OF THE W GULF WATERS.
