TROPICAL STORM ALMA DISCUSSION NUMBER   5
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL   EP012008
200 PM PDT THU MAY 29 2008
 
SATELLITE IMAGES INDICATE THAT THE EYE FEATURE IS CROSSING THE
NORTHERN PACIFIC COAST OF NICARAGUA NEAR THE CITY OF LEON.  THE
CLOUD PATTERN CONSISTS OF A VERY TIGHT CONVECTIVE COIL SURROUNDING
THE EYE FEATURE. DVORAK T-NUMBERS SUPPORT AN INITIAL INTENSITY OF
55 KNOTS. SINCE THE CENTER IS ALREADY MOVING INLAND AND A LARGE
PORTION OF THE CIRCULATION IS ALREADY INTERACTING WITH THE HIGH
TERRAIN...A GRADUAL WEAKENING IS ANTICIPATED. HOWEVER...TORRENTIAL
RAINS SHOULD CONTINUE OVER A LARGE PORTION OF CENTRAL AMERICA.
 
ALMA IS MOVING TOWARD THE NORTH AT 8 KNOTS. THE CYCLONE SHOULD
GRADUALLY TURN MORE TO THE NORTHWEST AS A HIGH PRESSURE SYSTEM
BUILDS OVER THE GULF OF MEXICO...AS INDICATED BY THE GLOBAL MODELS.
THIS PATTERN SHOULD KEEP THE CYCLONE OVER LAND FOR THE NEXT 24 TO
36 HOURS UNTIL DISSIPATION.  THIS TRACK FORECAST IS CONSISTENT WITH
NUMERICAL GUIDANCE WHICH UNANIMOUSLY TURNS THE CYCLONE
NORTHWESTWARD AND WESTWARD OVER CENTRAL AMERICA.
