Re: EPAC: INVEST 98E
Disorganized showers and thunderstorms extending several hundred
miles south and southwest of Acapulco, Mexico, are associated with
a tropical wave. An area of low pressure is expected to form during
the next day or so, and environmental conditions appear conducive
for this system to become a tropical depression over the weekend
while it moves west-northwestward at 10 to 15 mph.

Re: EPAC: INVEST 98E
An area of low pressure developing several hundred miles southwest
of Acapulco, Mexico, is producing disorganized shower and
thunderstorm activity. Environmental conditions appear conducive
for additional development, and a tropical depression is likely
to form during the next couple of days while the system moves
west-northwestward at 10 to 15 mph, away from the coast of Mexico.

Re: EPAC: INVEST 98E
Satellite data indicate that the area of low pressure located
several hundred miles south of Manzanillo, Mexico, is becoming
better defined. Shower and thunderstorm activity has also been
increasing and becoming better organized, and a tropical depression
is likely to form later tonight or on Friday while the system moves
west-northwestward at 10 to 15 mph, away from the coast of Mexico.

is likely to form later tonight or on Friday while the system moves
west-northwestward at 10 to 15 mph, away from the coast of Mexico.

Re: EPAC: INVEST 98E
Likely classifiable now. RapidScat and visible imagery suggests a closed center, and this has become much more organized.

It's looking really good. Not sure if they'll pull the trigger or wait another cycle or two.

Re: EPAC: INVEST 98E
Satellite presentation seems to be degrading for now.
As for the intensity forecast., this has 3 days over 27C+ waters to deepen, not taking into account the upwelling from the previous 3 storms. Should be enough for a minimal hurricane, but I'd be surprised if this was anything more than a Cat 1/2.

Re: EPAC: INVEST 98E
Shower and thunderstorm activity associated with an area of low
pressure located a few hundred miles south of Manzanillo, Mexico,
continues to gradually become better organized. Satellite wind
data indicate that the circulation is well defined, and conditions
are conducive for the development of a tropical depression later
today or tonight. This system is expected to move west-
northwestward at 10 to 15 mph, away from the coast of Mexico over
the next couple of days.
* Formation chance through 48 hours...high...90 percent

Re: EPAC: INVEST 98E
This was from 04Z last night. Only needs a solid convective burst and it will be a TC.

Re: EPAC: SIX-E - Tropical Depression
TROPICAL DEPRESSION SIX-E DISCUSSION NUMBER 1
NWS NATIONAL HURRICANE CENTER MIAMI FL EP062016
900 AM MDT FRI JUL 15 2016
The eastern North Pacific July tropical cyclone outbreak continues.
Visible satellite and overnight ASCAT data indicate that the large
low pressure area located southwest of the coast of Mexico has
acquired a well-defined circulation and enough convective banding
to classify the system as a tropical cyclone. This marks the fifth
tropical cyclone formation in the eastern Pacific this month. The
earlier ASCAT data showed maximum winds of 25 to 30 kt, and this is
the basis for the initial wind speed of 30 kt. The depression is
forecast to remain over warm water and in a low-shear environment
during the next few days, but the large size and current lack of
inner-core convection will likely result in only gradual
strengthening through tonight. After that time, steady strengthening
is forecast, and the cyclone is forecast to become a tropical storm
by early Saturday, and reach hurricane strength in a couple of days.
After that time, the system is expected to move over water that has
been cooled by the previous couple of hurricanes, and only a little
additional intensification is predicted. The NHC intensity forecast
is a little lower than the SHIPS guidance, and follows the
multi-model intensity consensus closely.
The initial motion of the depression is a somewhat uncertain 290/7
kt. A climatological west-northwestward heading is forecast through
the entire forecast period, to the south of a strong mid- to
upper-level ridge extending westward from northern Mexico. The
track guidance is in very good agreement, and the NHC forecast is
near the middle of the model envelope.
