SYNOPSIS FOR THE E PACIFIC WITHIN 250 NM OF CENTRAL AMERICA,
COLOMBIA, AND WITHIN 750 NM OF ECUADOR
913 PM PDT FRI JUN 5 2026
SYNOPSIS
SW SWELL WILL CONTINUE TO PROPAGATE INTO THE
REGIONAL WATERS, MAINTAINING MODERATE TO ROUGH SEAS THROUGH SAT
MORNING. NEW LARGER SW SWELL IS EXPECTED TO ARRIVE SAT NIGHT,
PROPAGATING NORTHEASTWARD AND INTO THE AREA COASTAL WATERS BY
LATE SUN, BUILDING SEAS TO 7 TO 10 FT. SW TO W MONSOONAL WINDS
ARE EXPECTED TO STRENGTHEN SAT NIGHT THROUGH SUN AND AID IN THE
DEVELOPMENT OF LOW PRESSURE OFFSHORE OF CENTRAL AMERICA.
DISORGANIZED SHOWER AND THUNDERSTORM ACTIVITY IS ALREADY
OCCURRING ACROSS THESE WATERS THIS AFTERNOON. ENVIRONMENTAL
CONDITIONS APPEAR CONDUCIVE FOR DEVELOPMENT OF THIS LOW PRESSURE
SYSTEM, AND A TROPICAL DEPRESSION COULD FORM DURING THE NEXT
SEVERAL DAYS WHILE IT MOVES SLOWLY NORTHWARD TOWARD THE COAST OF
CENTRAL AMERICA. REGARDLESS OF DEVELOPMENT, FRESH TO STRONG
MONSOONAL WINDS WILL INCREASE OVER THE WEEKEND, LIKELY LEADING
TO HEAVY RAINFALL ACROSS PORTIONS OF NICARAGUA, EL SALVADOR, AND
GUATEMALA. CURRENTLY, THIS SYSTEM HAS A MEDIUM CHANCE OF
TROPICAL CYCLONE FORMATION WITHIN THE NEXT 7 DAYS.
