..SPECIAL FEATURES
SIGNIFICANT RAINFALL OVER CENTRAL AMERICA:
A FRONTAL BOUNDARY HAS STALLED FROM THE TURKS AND CAICOS ISLANDS,
SOUTHWESTWARD ACROSS EXTREME EASTERN CUBA TO THE N COAST OF
HONDURAS. FRESH TO STRONG N TO NE WINDS PREVAIL NORTH OF THE
FRONT. THIS SCENARIO IS PRODUCING STRONG AND MOIST ONSHORE FLOW,
PARTICULARLY INTO THE NORTHERN COAST OF HONDURAS AND NE NICARAGUA,
LEADING TO SCATTERED SHOWERS AND THUNDERSTORMS. SCATTERED MODERATE
TO STRONG CONVECTION IS OCCURRING IN THE WESTERN CARIBBEAN,
GENERALLY WEST OF 80W AND SOUTH OF 18N. A MIDDLE TO UPPER LEVEL
RIDGE WILL EXTEND INTO THE W CARIBBEAN AND CENTRAL AMERICA BY
THURSDAY, WEAKENING THE FRONTAL BOUNDARY AND LEADING TO LESS
PRECIPITATION OVER EASTERN HONDURAS. THE BOUNDARY WILL THEN SLOWLY
MOVE NORTHWARD, LEADING TO HEAVY PRECIPITATION OVER NORTHERN
BELIZE AND SOUTHERN QUINTANA ROO-MEXICO FROM THURSDAY INTO FRIDAY
MORNING. MEANWHILE, A LOWER LEVEL TROUGH WILL CONTINUE TO PRODUCE
HEAVY PRECIPITATION OVER NICARAGUA AND COSTA RICA THROUGH FRIDAY,
WITH THE HEAVIEST RAINFALL OCCURRING DURING THE AFTERNOON HOURS ON
THURSDAY AND FRIDAY. THIS RAINFALL IS LIKELY TO RESULT IN LIFE-
THREATENING FLASH FLOODING AND LANDSLIDES. THIS INFORMATION WAS
PROVIDED BY THE INTERNATIONAL DESK AT THE WEATHER PREDICTION
CENTER.
PLEASE REFER TO YOUR LOCAL METEOROLOGICAL SERVICE FOR MORE
DETAILS.
AGADIR GALE WARNING: THE PRESSURE GRADIENT BETWEEN A STRONG
STATIONARY LOW IN THE NE ATLANTIC AND HIGHER PRESSURES OVER N
AFRICA AND N ITALY WILL LEAD TO SUSTAINED STRONG TO NEAR-GALE
FORCE SW WINDS OFFSHORE AGADIR LATER THIS EVENING AND OVERNIGHT.
GUSTS EXCEEDING GALE FORCE CAN BE EXPECTED, AND METEO-FRANCE HAS
ISSUED A GALE WARNING FOR THE AGADIR ZONE FROM 13/03 UTC THROUGH
