Tehuantepec is associated with a westward-moving tropical wave.
Environmental conditions are forecast to be conducive for
development of this system over the next several days, and a
tropical depression is expected to form well south of the coast of
Mexico over the weekend.
* Formation chance through 48 hours…medium…50 percent.
* Formation chance through 5 days…high…90 percent.

2. Another tropical wave is forecast to move over southern Central
America later today, and then move into the far eastern Pacific by
late Friday. Environmental conditions should support some
development early next week south of Central America while the
system moves westward to west-northwestward.
* Formation chance through 48 hours…low…near 0 percent.

Atlantic satellite image:

The Global Infrared Satellite image shows clouds by their temperature. Red and blue areas indicate cold (high) cloud tops. Infrared (IR) radiation is electromagnetic radiation whose wavelength is longer than that of visible light, but shorter than that of terahertz radiation and microwaves. Weather satellites equipped with scanning radiometers produce thermal or infrared images which can then enable a trained analyst to determine cloud heights and types, to calculate land and surface water temperatures, and to locate ocean surface features.
