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.

...SPECIAL FEATURES...

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.
