SYNOPSIS FOR THE E PACIFIC WITHIN 250 NM OF CENTRAL AMERICA,
COLOMBIA, AND WITHIN 750 NM OF ECUADOR
753 PM PDT THU JUN 4 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 AS DESCRIBED
ABOVE. ENVIRONMENTAL CONDITIONS APPEAR CONDUCIVE FOR DEVELOPMENT
OF THIS SYSTEM, AND A TROPICAL DEPRESSION IS LIKELY TO 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 HIGH CHANCE OF TROPICAL CYCLONE FORMATION IN 7
DAYS.
