I know this is not a invest but I think it should be because the models have been making a lot of noise about this system. Mods can change the title if they want.
A broad area of low pressure is expected to form over the
southwestern Caribbean Sea in a couple of days from a tropical wave
currently located over the central Caribbean Sea. Environmental
conditions are forecast to be conducive for development of the low
if it remains over water, and a tropical depression could form late
this week or this weekend while the system moves northwestward over
the northwestern Caribbean Sea, across the Yucatan Peninsula of
Mexico, and into the southwestern Gulf of Mexico by Sunday.
* Formation chance through 48 hours...low...10 percent.
* Formation chance through 5 days...medium...60 percent.
