VALID 00Z FRI 31 JUL 2026 - 00Z FRI 07 AUG 2026
THE RECENT DISRUPTION TO THE TRADES CAUSED BY FAUSTO MOVING WELL
NORTH OF THE ISLANDS, ENDS EARLY THIS FORECAST PERIOD, WITH MORE
NORMAL TRADES EXPECTED FRIDAY INTO THE WEEKEND. THE AXIS OF HIGHER
THAN AVERAGE PW VALUES TRAILING TO THE SOUTH OF FAUSTO WILL LINGER
ACROSS THE ISLAND THROUGH FRIDAY, WITH LOWER THAN AVERAGE PW THEN
MOVING ACROSS THE ISLANDS THROUGH TUESDAY. TRADES WILL AGAIN
WEAKEN BY MONDAY AS UPPER TROFFING DEEPENS WELL TO THE NORTHEAST
OF THE ISLANDS ALONG 150-155W. THE DEEPENING TROF TO THE NORTHEAST
OF THE ISLAND WILL HELP DRAW ABOVE AVERAGE PW VALUES BACK ACROSS
THE ISLANDS WEDNESDAY AND THURSDAY. THE RETURN TO NORMAL TRADES
WILL ALLOW PRECIP TO RETURN TO MORE CLIMATOLOGICAL GEOGRAPHIC
NORMS. THE INCREASING PW LATE THIS PERIOD, MAY SUPPORT HEAVIER
TRADE SHOWERS.
