AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN JUAN PR
517 AM AST FRI OCT 23 2009

DISCUSSION...THE CAPECO/GULF TANK FARM EXPLOSION AND FIRE IN
SOUTHERN CATANO HAS DOMINATED THE WEATHER FOCUS THIS SHIFT. WINDS
ARE SOUTHEAST AT LOWER LEVELS DUE TO THE HIGH PRESSURE AND NEARLY
CALM AT THE SURFACE. THIS SITUATION WILL CONTINUE UNTIL SEA BREEZE
INFLUENCES CAN OVERCOME THE GENERAL FLOW AND FORCE SOME OF THE
SMOKE PLUME BACK INTO NORTH CENTRAL PUERTO RICO. TIMING...
DURATION AND WIND SPEEDS OF THE SHIFT FROM THE GENERAL FLOW TO
THE SEA BREEZE CONDITIONS ARE UNCERTAIN AND WINDS MAY VACILLATE
BETWEEN THE TWO CONDITIONS DURING THE DAY AS THE GENERAL FLOW
FIGHTS THE INFLUENCE OF THE SEA BREEZE. WINDS WILL CARRY THE PLUME
OUT TO SEA AT LEVELS ABOVE ABOUT 3 TO 5 THOUSAND FEET...BUT DUE TO
UNSTABLE CONDITIONS SMOKE MAY RISE TO ABOVE 15 THOUSAND FEET FROM
TIME TO TIME DURING THE DAY. SMOKE SHOULD DISPERSE WIDELY AFTER
ABOUT 10 AM AST. SCATTERED SHOWERS ARE EXPECTED BUT SHOULD BE
CONFINED TO NORTHWEST PUERTO RICO TODAY. ISOLATED SHOWERS ARE
EXPECTED ELSEWHERE. THE NORMAL DIURNAL SHOWER PATTERN WILL
CONTINUE THROUGH TUESDAY. AFTER THE UPPER LEVEL LOW MOVES PAST
PUERTO RICO MODELS INDICATE BETTER MOISTURE OVER THE AREA AND
BETTER DYNAMICS SHOULD CONTRIBUTE TO INCREASED PRECIPITATION
WEDNESDAY AND THURSDAY.
