Synopsis for the E Pacific within 250 nm of Central America,
Colombia, and within 750 nm of Ecuador
145 AM PDT Mon Jun 8 2026

.SYNOPSIS...Low pressure, Invest EP92, offshore of Central 
America has showers and thunderstorms which are starting to show 
signs of organization. Environmental conditions appear conducive 
for further development of this system, and a tropical depression
is likely to form during the next day or two while the system 
moves slowly northward and then northwestward toward the coast of
Central America. Interests along the Pacific coasts of 
northwestern Costa Rica, Nicaragua, Honduras, El Salvador, and 
Guatemala should monitor the progress of this system, as heavy 
rainfall and life-threatening flash flooding are possible through
the middle portion of this week. Gale-force winds are forecast 
with this system regardless of tropical development by this 
afternoon if not sooner. Otherwise, large, long period cross- 
equatorial swell with seas of 8-12 ft will continue to impact the
offshore waters through the early part of the week resulting in 
large surf at the coasts. Refer to your local meteorological 
information for more details in the surf zone. Mainly gentle to 
moderate winds will prevail away from Invest EP92 through the 
week.
