Disorganized showers and thunderstorms located just over 1000 miles
southwest of the southern tip of the Baja California peninsula are
associated with a trough of low pressure. Environmental conditions
are forecast to be conducive for some development during the next
few days, and a tropical depression could form later this week while
the system moves west-northwestward at around 15 mph.
* Formation chance through 48 hours...low...30 percent.

I wish I could be that optimistic.

[Chris90]

We might be able to squeeze out a hurricane from this. I have my hopes and dreams.

I wish I could be that optimistic.

I'm losing optimism with each passing day. The storms in this basin this year are a bunch of exhibitionists, they love exposing their LLCs.
The only reason why I'm somewhat optimistic with this one is because it's far enough west. Storms have been doing better farther out here. My cynicism increases the closer storms are to Mexico. Henriette already burned me in the past 24 hours. I thought a mid-grade TS was decently possible, said so, and she promptly stripped off her convective outfit and left her LLC out there for the whole world to see.

[Yellow Evan]

Disorganized showers and thunderstorms located just over 1000 miles
southwest of the southern tip of the Baja California peninsula are
associated with a elongated trough of low pressure. Environmental
conditions are forecast to be conducive for gradual development
during the next few days, and a tropical depression is likely to
form later this week while the system moves west-northwestward at
10 to 15 mph.

[Yellow Evan]

Disorganized showers and thunderstorms located about 1100 miles
southwest of the southern tip of the Baja California peninsula are
associated with an elongated trough of low pressure. Environmental
conditions are forecast to be conducive for some development during
the next few days, and a tropical depression could form later this
week while the system moves west-northwestward at 10 to 15 mph.
* Formation chance through 48 hours...medium...40 percent.
* Formation chance through 5 days...medium...60 percent.

Down to 10/10.

[AJC3]

An elongated area of low pressure located about 1700 miles west of
the southern tip of the Baja California peninsula is producing
intermittent showers and thunderstorms. Environmental conditions are
not conducive for development and tropical cyclone formation is not
anticipated. The low is forecast to move generally westward at 10 to
15 mph for the new couple of days.
* Formation chance through 48 hours...near 0 percent.
* Formation chance through 5 days...near 0 percent.
