SYNOPSIS FOR THE E PACIFIC WITHIN 250 NM OF CENTRAL AMERICA,
COLOMBIA, AND WITHIN 750 NM OF ECUADOR
1245 AM PDT FRI JUN 5 2026
SYNOPSIS
SW SWELL WILL CONTINUE TO PROPAGATE ACROSS THE
REGIONAL WATERS, MAINTAINING MODERATE TO ROUGH SEAS THROUGH SAT
MORNING, WITH HIGHEST SEAS AROUND 8 FT EXPECTED BETWEEN ECUADOR
AND THE GALAPAGOS ISLANDS. A NEW SET OF LARGER SW SWELL IS
EXPECTED TO ARRIVE BY SAT NIGHT, PROPAGATING NE INTO EARLY NEXT
WEEK AND BUILDING SEAS TO 7 TO 10 FT AT A MINIMUM. OTHERWISE,
A TROUGH OF LOW PRESSURE OFFSHORE OF CENTRAL AMERICA IS
PRODUCING SOME DISORGANIZED SHOWER AND THUNDERSTORM ACTIVITY.
ENVIRONMENTAL CONDITIONS APPEAR CONDUCIVE FOR DEVELOPMENT OF THIS
SYSTEM, AND A TROPICAL DEPRESSION COULD FORM DURING THE NEXT
SEVERAL DAYS WHILE IT MOVES SLOWLY NORTHWARD. REGARDLESS OF
DEVELOPMENT, MONSOONAL SW TO W WINDS WILL INCREASE SOUTH OF THE
MONSOON TROUGH OVER THE WEEKEND. CURRENTLY, THIS SYSTEM HAS A
MEDIUM CHANCE OF TROPICAL CYCLONE FORMATION IN 7 DAYS.
