NWS NATIONAL HURRICANE CENTER MIAMI FL
500 PM PDT SUN MAY 18 2014

For the eastern North Pacific...east of 140 degrees west longitude:

Systems with the potential to become a tropical cyclone during the
next 48 hours...

A large but disorganized area of cloudiness and thunderstorms
located several hundred miles south of southwestern Mexico is
associated with an elongated area of low pressure. Development of
this system, if any, should be slow to occur during the next
day or two. After that time, environmental conditions are forecast
to become unfavorable for tropical cyclone formation.
* Formation chance through 48 hours...low...20 percent
* Formation chance through 5 days...low...20 percent

Under a TCFA but only a LOW chance to develop. Probrably they don't want to increase the potential due to it's far location from any landmass with no harm to humans :D and if upgraded will just be weak...

Well it's lost almost all its convection now. It's nothing but some sad looking clouds and it certainly looks worse than any 30 knot invest I can remember. It looks like a random and disorganized patch of clouds right now, and I personally don't see this developing at all unless conditions improve. After all, storms do not form this far out and at this low latitude in May. However, I am not an expert, so maybe they are seeing something I can't, and don't use this as official.

Systems with the potential to become a tropical cyclone during the
next 48 hours...

An elongated area of low pressure located several hundred miles
south of the southern tip of the Baja California peninsula is
producing disorganized shower activity. Any development of this
system should be slow to occur during the next day or two while it
moves westward or west-northwestward. After that time,
environmental conditions are expected to become unfavorable for
tropical cyclone formation.

I agree, time to move on to something worthwhile.

As of this morning, on EPAC imagery, it's hard for me to recognise 91E. There isn't much there with the exception of a few leftover clouds. There is also no organisation, no banding, nothing characteristic of an invest with potential to develop.

An elongated area of low pressure located several hundred miles
south of the southern tip of the Baja California peninsula is
moving slowly westward. Associated shower activity remains
disorganized, and development of this system is becoming less
likely due to unfavorable environmental conditions.

No queda nada más cierto desorden. Once used to be an organizing disturbance turns out to be nothing left. Adios! At least I expected something less than 45 knots, 15 knots. :lol:

Next.

An elongated trough of low pressure located several hundred miles
south of the southern tip of the Baja California peninsula is
moving little. Associated shower activity has decreased
significantly this morning, and development of this system is
unlikely due to unfavorable environmental conditions.

Goodbye 91E, you became as much as 90E did. :)
