The Potential for flash floods and landslides for Central America still persist as the central American Gyre will be enhancing heavy rainfall over this region starting today.

Global models continue to suggest a Central American Gyre (CAG)
will form across the southwest Caribbean and Central America by
Fri, and then gradually shift west to northwest across Central
America through early next week. CAGs tends to enhance the
strength of SW monsoon flow, and lift the monsoon trough well
north of its typical position. This will increase convergent
surface winds and advect abundant moisture northward, triggering
widespread strong convection over Central America. Expect heavy
rainfall commencing across Panama and Costa Rica today, then
spreading to parts of Guatemala and Honduras. Extreme rainfall is
possible across the Pacific coasts of these countries, and also
over southern Honduras and northeast Nicaragua. This will
increase the potential for flash flooding and mud landslides,
especially near valleys in mountainous terrain. Please refer to
products issued by your local weather service for more
information.
