AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN JUAN PR
1201 PM AST SAT DEC 6 2003

GENERAL FORECAST LEFT UNCHANGED...HOWEVER MAJOR CHANGES TO THE
COASTAL WATERS FORECAST TO BRING IN A SOUTH TO SOUTHEAST SWELL AS A
RESULT OF TS ODETTE...ESPECIALLY ACROSS THE MONA PASSAGE. ADDITIONAL
MODIFICATION WILL BE MADE IN THE COASTAL GRIDS DURING FOR THE 4 PM
PACKAGE. HSA TO CONTINUE FOR THE ATLANTIC COASTAL SECTIONS BUT WILL
LIKELY BE DROPPED LATER THIS AFTERNOON.

THIS WILL INTENSIFY AN ALREADY DANGEROUS SITUATION AS THE RIVERS
ALONG THE SOUTH COAST ARE VERY FLASHY AND RAINFALL WILL NOT BE
ALLOWED TO EXIT IN TO THE OCEAN WHICH WILL RESULT IN A PILING UP OF
WATER ALONG THE RIVERS FORCING RIVERS OUT OF THEIR BANKS. THE
SOUTHEAST SECTIONS OF PUERTO RICO ARE UNDER FLASH FLOOD WARNINGS AND
WILL CONTINUE TO DO SO AS HEAVY SHOWERS CONTINUE TO MOVE ACROSS THE
AREA.

EASTERN HISPANIOLA THROUGH THE MONA PASSAGE...WESTERN PUERTO RICO
AND INTO THE ATLANTIC. HOWEVER...BESIDE SPOTTY AREAS OF HEAVY

AN AREA OF SHOWERS FORMING SOUTHEAST OF PUERTO RICO WILL BE
AFFECTING THE SOUTHEAST AND SOUTH COAST THE REST OF THE EARLY
