Nicaragua and northern Costa Rica through this evening, and emerge
off of the Pacific coast of southern Nicaragua or northern Costa
Rica by early Friday.

accumulations of 3 to 6 inches with total rainfall amounts of up to
10 inches over the higher terrain of far western Panama and southern
Costa Rica through Friday.
Additional rainfall amounts of 1 to 3 inches can be expected tonight
