NARRATIVE SYNOPTIC DISCUSSION FOR AMERICAN SAMOA AND THE
INDEPENDENT STATE OF SAMOA

...TONIGHT THROUGH WEDNESDAY...

LAYERED CLOUDS CONTINUE TO BE FOUND ACROSS SAMOA THIS AFTERNOON. THE
THICKEST LAYERED CLOUDS LIE JUST TO THE SOUTH OF THE ISLANDS WHERE A
TROUGH CONTINUES TO BE FOUND. WIDELY SCATTERED SHOWERS ARE FOUND IN
YOUR AREA WITH AN ISOLATED THUNDERSTORM OR TWO. TROPICAL CYCLONE
PAULA IS LOCATED ABOUT 1670 MILES TO THE EAST OF SAMOA...BUT WILL
LIKELY NOT DIRECTLY IMPACT SAMOA OVER THE NEXT COUPLE OF DAYS. LOOK
FOR MOSTLY CLOUDY SKIES TO CONTINUE WITH A FEW SHOWERS. A
THUNDERSTORM OR TWO CANNOT BE RULED OUT AS WELL. WINDS WILL BE
NORTHWEST AT 5 TO 15 MPH.

BINARY DATA SUGGEST A FRESH NORTHWEST SWELL OF 3 TO 4 FT ARRIVING
TONIGHT.

...OUTLOOK FOR THURSDAY THROUGH SATURDAY...

MOSTLY CLOUDY SKIES WITH A FEW SHOWERS WILL CONTINUE THROUGH THE
EXTENDED PERIOD. SHOULD ANOTHER TROPICAL SYSTEM DEVELOP TO YOUR
SOUTHEAST AS HINTED AT IN THE AVN MODEL...YOU WILL SEE AN INCREASE
IN NORTHWESTERLY WINDS TO 15 TO 20 KNOTS.

NARRATIVE DISCUSSION FOR TUVALU

SCATTERED CLOUDS ARE OVER MUCH OF TUVALU WITH MOSTLY CLOUDY SKIES
OVER THE SOUTHERN ATOLLS. TROPICAL CYCLONE PAULA IS LOCATED ABOUT
1050 MILES TO YOUR WEST-SOUTHWEST BUT WILL HAVE LITTLE IMPACT ON
YOUR ISLANDS. EXPECT VARYING AMOUNTS OF CLOUDS WITH THE HEAVIEST
CONCENTRATION OVER THE SOUTHERN ISLANDS. PASSING SHOWERS WILL ALSO
BE POSSIBLE WITH NORTHEAST WIND 5 TO 15 KT.
