FOR THE EASTERN NORTH PACIFIC...EAST OF 140 DEGREES WEST LONGITUDE..
SHOWERS AND THUNDERSTORMS ASSOCIATED WITH AN AREA OF LOW PRESSURE
LOCATED ABOUT 400 MILES SOUTH-SOUTHEAST OF ACAPULCO MEXICO HAVE
CONTINUED TO BECOME BETTER ORGANIZED TODAY. ENVIRONMENTAL
CONDITIONS APPEAR CONDUCIVE FOR FURTHER SLOW DEVELOPMENT...AND THIS
LOW COULD BECOME A TROPICAL DEPRESSION DURING THE NEXT DAY OR TWO.
THERE IS A HIGH CHANCE...60 PERCENT...OF THIS SYSTEM BECOMING A
TROPICAL CYCLONE DURING THE NEXT 48 HOURS
AS IT MOVES SLOWLY
NORTHWESTWARD.

This system doesn't look too bad right now, could well end up forming but the models have backed off with this one at the moment.

There's alot of spread in the BAM suite models which suggests that the upper level environment isn't going to be very conducive for strengthening - different directions of wind flow at different levels of the atmosphere imply a sheared environment.

But it does look good right now, and the models seem to be sniffing a weakness in the ridge. This could be one for Mexico to watch, even if it ends up being mainly a rainmaker.

This one is getting there but will it make it before it hits land which is looking increasingly possible at the moment.

Looks like even if the system doesn't make landfall its going to be close enough to probably somewhat disrupt this system...though that obviously doesn't preclude development!

Looks like most of the convection has moved inland:

But maybe "center" still hanging offshore?:

Its very close to land indeed, I'd imagine it'll probably end up just moving inland from the looks of things.
